SiN is a first-person shooter developed by Ritual Entertainment (formely known as Hipnotic Interactive) – who previously made the Scourge of Armagon Mission Pack for Quake – released in 1998. Even though the game received generally favorable reviews from critics and even got a small cult following, SiN has ultimately lost in the competition with Half-Life. Despite the Wages Of Sin addon, a planned series of episodic games and a full-length anime film, the SiN franchise was never able to get the attention of a large audience and was ultimately abandoned and forgotten. In 2020 Nightdive Studios decided to re-release the original game and it’s addon as SiN: Gold, however, the updated edition still barely brought back the interest to the franchise. Later in 2021 Nightdive Studios announced a full-fledge remaster called SiN: Reloaded, yet as for 2025 the project is put on halt for an unknown time.

Because I almost could not find any guides for SiN online and there is generally little information on the game itself, I decided to write my own “secrets, objectives, and bonus missions” one to help the others beat the game on (or at least almost on) 100%. Before the main part though, I want to share some useful information about the game itself, which will help you in your playthrough.




1) I highly recommend playing on the Dominatrix[rohit.itch.io] source port as it properly scales the HUD for modern resolutions, adds a few extra options in the settings, and allows you to rebind all buttons via the config file in %appdata%/dominatrix/base/config.cfg (unfortunately, there is still no way to bind “reload” to a different button). If you are having trouble with the in-game monitors not fitting properly for your resolution simply change the FOV in the settings.

2) In SiN armor is very important – without it your HP will drain very quickly with each hit. It is displayed in the lower right corner and is separated into: helmet, torso, legs. The HP bar is one for the entire body. Enemies wear armor too and depending on what part of the body you are shooting at, the armor for that part will be damaged too once you loot the enemy’s corpse. So, for example, if you are lacking leg armor try to avoid shooting at the enemies’ legs.

3) The game can be very scarce for ammo, so try to use the best out of each weapon and save deadlier guns for deadlier enemies.

4) Similar to the ammo, some of the game’s levels are very scarce for health and armor pickups, so I highly recommend avoiding moving to next mission nearly dead. The missions that do restore your HP and armor at the start are: 6, 12, 13, 19.

5) Chaingun and Plasma Gun have alternative fire modes - press RMB (by default) to switch to them. Quantum Destabilizer shots can be charged by holding LMB; remember that it uses the same ammo type as Plasma Gun. Sniper Rifle activates zoom with RMB which deals significantly more damage than no scope shots. To be able to place several Spider Mines at once, press the weapon-assigned button to switch between the remote controller and the mines.

6) Plasma Gun is a semi-secret weapon that you will fully access only before the final fight. However, the game will give you two chances to get it earlier by collecting weapon parts scattered through the missions. There are two sets of parts - in the first and in the second half of the game; nonetheless, if you assemble Plasma Gun in the first half, in the second one the weapon parts will be absent. The missions that have weapon parts located on them are: 6, 7, 9, 20, 24, 25, 26.

7) The Speargun you get on Mission 20 is not assigned to any button by default, and unfortunately cannot be assigned even with the source port, so use the weapon wheel for swapping to it.

8) The game has the same door problem as the Build Engine games – they can damage and kill you when you get in their way. Moreover, the interact button is both responsible for picking up items and opening lockers, so be extra careful when vacuum cleaning closets for supplies.

9) I recommend playing on the medium difficulty (Officer) and avoid the max one (HardCorps), unless you are a masochist and ready for constant saving and loading. It is quite poorly balanced and you can easily end up in a situation with only machine gun ammo and 10 HP left against armored troops of chaingun and rocket launcher soldiers.

10) I recommend saving at the start of each level, so in case things go south you could always return to the start of the mission.

11) Remember that if you have a hard time finding something, you can always use the /noclip command to enable no-clip and explore the level from out of bounds.

Note 1: I decided not to create Primary Objectives subsection for each mission because most of the primary objectives are ticked off automatically as you progress through the game. However, I left hints for the missions that can be exited without finishing all the primary objectives.

Note 2: Some of the missions require you to collect/destroy all particular items or save all hostages scattered throughout the level. I decided not to include the spots of each individual hostage/item, since they are located in mostly obvious spots and the levels themselves are relatively small and most of them are backtrackable. Still, if you have trouble finding all hostages/items, remember to utilize the advice number 9.

Destroy all three trees in front of the bank's entrance and look at the building in front of you. A metallic man on a police motorcycle will ride out of window right into your chopper. This is a reference to a scene from the movie Terminator 2: Judgement Day.

If you shoot the billboard on the roof above the bank, it will fall down through the glass roof alternating the regular start of the next mission. However, if you let enemy rockets hit the chopper enough times, the pilot shouts, "controls are not responding" and the chopper will start to slowly descend. If it is not destroyed during the emergency landing, you will start the next mission on the street outside the bank. Nonetheless, going for that alternative starting point makes it much trickier to destroy all the turrets on this mission, thus completing all the primary objectives.



After the chopper turns around immediately shoot the crack in the right pillar at the banks entrance to crash the archway. The objective should be ticked off shortly.

You can pick up a coin in the fountain in front of the tellers’ counter and then use it at the telephones at the start of the level; a funny dialogue will play referencing the Evil Dead franchise.


You can open one of the drawers in the tellers' counter and take a pack of cash out of it; JC will make a witty comment on that.



In one of the rooms with a hostage, there is a portrait hanging on the wall. Interact with it to reveal a safe behind. Inside, there will be CD boxes of Sin Episodes - Emergence - the first episode of the cancelled episodic series of games that was supposed to be a sequel to SiN. In the original CD version of the game, there were boxes of Quake Mission Pack 1: Scourge of Armagon, which Ritual Entertainment (called Hipnotic Interactive back then) were the developers of, however, this secret was altered in the digital version of the game, when Sin alongside Sin Episodes - Emergence was released on Steam.



In the same terminal where you open the security doors and get the vault code, you can get access to the numbers and the PIN codes of the customers' accounts. There are two ways to do it. You can go to "Customer Accounts" menu and try to bruteforce the database by manually typing various account handles (customer surnames). However, there is a much better method, which is actually another easter egg. There is a "Command Prompt" option in menu which opens the terminal's console. This console actually supports real-life DOS commands and allows you to browse through the bank's file system. Unless you are not familiar working with DOS, here are the instructions how to get access to the custormers' data.

1) Select the "Command Prompt" option in the menu and press enter.
2) Type dir command and press enter, this will show you the list of folders and files in the current directory.
3) Type cd data and press enter, this will change the working directory to the data folder.
4) Type dir again and you will see the list of files in the data directory. There will be eight .pwd and one .ini file. The .pwd files contain the custormers' numbers and pincodes in the $account-number@pin-code format, the .ini file just contains this terminal's configuration settings.
5) Type type fcbsec01.pwd to see the contents of the fcbsec01.pwd file.
6) Now you can go through all the files like that by just changing the name of the required file before the type command and see all the account numbers and pincodes in the bank's database.

You can use the account numbers and PIN codes in the ATM machines located at the regular start of the level to tamper with the funds of the customers.


This secret is quite tricky and may require a few tries to get. Once you enter the vault, you can spot a health pickup lying on top of the deposit boxes wall. To get it, open the glass door into the deposit boxes room, jump onto the door's handle, then on top of the door, and finally make the jump onto the deposit boxes and take the health pickup. The door closes approximately 5 seconds after opening so you have to act fast.

At the very end of the level, one of the deposit boxes is actually openable and contains an evidence envelope inside. If you take it, the description text on the loading screen for the next mission will change.



Once you get to the security office, simply open all the security doors through the terminal.



There are several hostages located throughout the map. Make sure to avoid hitting them and once you kill all the enemies, interact with them so they can run away. Just explore the map thoroughly and remember to check the balconies in each hall. You will get the objective ticked off in a few seconds after the last hostage is saved. Unfortunately, the objective does not fail automatically if a hostage is killed, so be sure to save at the start of the level, just in case.

In the building where you need to walk up the beams to the roof, there are stairs going down in one of the corners. Follow them and you will end up in a small room with a pillar. Look closely into its far corner and you will see an opening. Crawl into it and you will end up in a small room with two bums, health pickups and glowsticks. Beware of the rats though.

After Mancini runs away once again and the wooden stairs to the third floor break under you, you will see another alleyway from the windows ledge. Jump down and find an opening with a bum inside. Crawl into it, then crawl under the fallen debris and shoot the pipe in the brick wall to blow it up. Crawl into the newly-created opening to get the secret. There are no items inside, however, interacting with the valve floods the elevator shaft on the next mission giving you access to one of the secrets there.


Most of the money bags are located in obvious places and can be easily spotted, so just explore level thoroughly. The entire mission is backtrackable except the booby-trapped basement but there are no moneybags before it. The bags that are kind of easy to miss are located in the large garbage container in the first alleyway. To get them, go the opened window on the second floor of the building where you need to walk up the beams to the roof. Crawl onto the window's ledge and jump into the container, it is a bit tricky but totally possible. The objective will be ticked off as soon as the last bag is collected.


1) Even though our protagonist is very badass, the rats still manage to bite him through the armor and drain his health, so beware of them on this and the next levels.

2) Remember that you can use glowsticks from your inventory to light up dark areas on this and the next levels. It is still very poor compared to an actual flashlight, but it's better than nothing.

Almost at the start of the mission, after you clear out the enemies in the alleyway and on the balconies above, go to the trash cans with a bum standing beside and there will be a quarter lying
between them.



Shortly after the previous hidden-not-a-secret, you climb to the balconies from the dumpster. After getting to the top look at the dark building to the right. You will see that one of the windows is slightly dented inside. Jump into it from the balcony to get some pistol ammo and food pickups.


After you make a jump from roof to roof, you will see a big AC unit right away. Destroy it and it will reveal a hidden went. Climb down into it and you will get into a small office with a shotgun, glowsticks, and some food pickups.


After you use the bulldozer to knock one of the beams on the first construction site, walk up that beam and climb up the nearby balcony. At the top you will see that one of the windows is slightly dented inside. Jump into it for some food pickups.

Closer to the end of the mission, you will come out of the pipes to another construction site. Deal with the enemies and walk towards the brick wall with a door ahead. There will be another quarter lying on the road.



Secret 4/4 (Inaccessible unless you collected Secret 2/2 on the previous mission) [/h3]
After you rescue the second hostage (see the objective below) walk up a small staircase and there will be a flooded elevator shaft to the left. Jump into the water and swim to the room below to find some health pickups. If you did not interact with the valve inside Secret 2/2 on the previous level, the shaft won't have any water and jumping down will instantly kill you, making this secret inaccessible.


After you jump down to the construction site and kill all the enemies, you will see a cabin with a door. Enter it but do not shoot the man inside; interact with him and he will give you the construction plans. The objective should be ticked off shortly.


There are two hostages on the level. One is located on the first rooftop you climb on and is easy to spot. The second one is a bit tricker. When you come out of the pipe to another construction site there will be two ways to proceed to the next level: break the door in the brick wall with a bulldozer or blow up a wooden fence and go through the flooded basement. Choose the latter one and once you swim out there will be the second hostage. To avoid getting tons of damage, try to climb under the wooden stairs on the left as soon as you jump out of the water. You will get the objective ticked off in a few seconds after the last hostage is saved. After that you can backtrack to the bulldozer in case you want to enter the next level from another side. Unfortunately, the objective does not fail automatically if a hostage is killed, so be sure to save at the start of the level, just in case.



1) After you come out of the dark corridor and fall into a pit there will be some pipes with a valve on the ground. Shoot the beams hanging from the crane above them to break the pipes and fill the pit with water. The inaccessible stairs with the double door are just a decoration, so there is no need trying to climb them.

2) After you jump down to the construction site/behind the barbed wire fence/into the pit, there will be no way to backtrack, so make sure you finished your business in the current part of the level.

3) If you choose the way through the wooden fence at the second construction site, you will shortly come out to a street with an ATV waiting for you. Even though the vehicle control in this game is terrible, you are invincible while riding one and can run over enemies to kill them.

Closer to the end of the level you will walk through the corridor with the escalators leading up on the right. Go up the escalators, turn right and there will be two telephones and a bum standing beside. The left telephone is broken and even though it requires a quarter to be used, it will actually spit out an additional coin. You can use it to interact with the working telephone on the right, however, if you collected all the quarters on the previous levels (you must have 3 of them by now then), you can save them for the next level to access a more interesting secret much later in the game.

Right after the previous hidden-not-a-secret, turn left from the telephones and walk to the end of the corridor. There will be a slightly visible crack in the wall on the right. Shoot it and inside the newly-opened passage you will find a foreshadowing of the game’s future events.



There will be a few bums standing in different parts of the level. Just avoid shooting them and once the mission is finished the objective will be ticked off on the loading screen. Unfortunately, the objective does not fail automatically if a civilian is killed, so be sure to save at the start of the level, just in case. Also when you will be approaching the end of the level, the mutant will kill one of the civilians before you; this is a scripted scene which does not affect the objective.



Just like in Mission 2 the money bags are scattered throughout the level and can be easily spotted. Just explore the level thoroughly and you should find all of them. The objective will be ticked off as soon as the last bag is collected. Beware though, that after you pass through the newly-opened passage from the big hall with bathrooms and escalators (see the picture below), the ceiling behind you will collapse and you won’t be able to backtrack, so make an extra save before that just in case.



1) Remember that once you sit on the train after passing through the corridor with the escalators leading to Hidden-Not-A-Secret 1/1, it will take you to the mission’s ending, so make sure to finish your business and collect all the moneybags before that.

Note: this is supposed to be a stealth mission but as you may guess, the stealth in this game is very broken. The enemies will spot you instantly if you cross their line of sight and will hear you instantly unless you crouch or walk, so I highly recommend turning off the “Always Run” option in the settings for this mission. Below, in the Secondary Objectives section, I will describe how to complete this mission collecting all the hidden-not-secrets and the weapon part without triggering the alarm. Also the guide section for this mission exceeded Steam character limit, so I had to split it into two parts.

On the second floor of the guards’ office, you can see a vent behind the window. You can shoot it with your pistol and jump into it from the fan. Crawl through it and you will find a large fan shaft with an interactable fuse box. You can open and shoot it which will turn off the fan in the next mission.



There is a vending machine in the cafeteria that can be used If you saved three quarters collected on the previous missions. Put the coins one by one by interacting with it and you will get a candy bar into your inventory. Unfortunately, you cannot use it to restore your health, however, it will prove handy much later on Mission 18: Freeport Waterworks – Part 2.

In the shower room, there is a breakable floor that unlocks access to a small vent giving you a glimpse of the next mission.



In one of locked the labs with the toxic goo floor, there is a weapon part lying on one of the shelves. Jump into that lab through the window, drop onto the table, take the component without falling down, and jump back out through the same window. For more info on how to get to that lab, see the Secondary Objectives section below.



See Secondary Objectives and Hints in the next section...

Remember to turn off the “Always Run” setting! At the start of the mission walk slowly towards the entrance, stand at an angle to the window and the door, so the secretary won’t see you. Wait until she leaves into the corridor (picture 1), and then quickly sneak into her office (picture 2), and hide behind the wall near the door (picture 3). As soon as she walks back, in quickly knock her out with you fists and carefully proceed to the corridor she initially walked into. There will be a guard standing at the other end (picture 4), wait until he leaves, then crouch under the windows hugging the right wall until you reach the end of the corridor. As you crouch past the windows, the staff inside the office will say something like “I swear I saw something” or “I think I heard something” – do not worry, these are scripted lines and they do not fail stealth.

When you reach the end of the corridor, turn right and you will come to the guards’ office. Go to the stairs leading up (picture 5) and shot them all. Do not worry – shooting in this room does not trigger the alarm. Collect the loot from corpses and one of them will have a silencer for you pistol, which can be useful in the subsequent levels. If you want to access Hidden-Not-A-Secret 1/3, shoot the window and the vent, then jump onto the fan and then into the vent (picture 6). Crawl through the vents and get to the fan shaft. Open the fuse box, make some distance, so the explosion won’t hurt you and shoot it (picture 7). The fan will stop and you can return back. There is another exit from the vents into the corridor below but I highly recommend returning back to the guards’ office, so you won’t trigger the alarm and get lost.

Picture 7


From the guards’ office, return to the corridor you came from and sneak into the first corridor on the right (picture 8). There you will see an elevator that requires a keycard and another corridor on the left (picture 9). Crawl under the windows hugging the right wall and quickly sneak to the left into yet another corridor. In that corridor you will see the door into the changing room on the left (picture 10). Go inside, and there will be the door to the Hidden-Not-A-Secret 2/3 on the right (picture 11). If you are going for it, there will be 2 staff members behind the door which will run for help as soon as they see you, so be ready to knock them out. After that, return to the door you came from and there will be a vending machine to the right of it (picture 12). Interact with it three times to use the quarters and get the candy bar in return.

Return back to the changing room, walk past the wall, and then turn right (picture 13). You will see some lockers in front of you and in one of them, you will find a suit and a keycard for the elevator (picture 14). If you want to access Hidden-Not-A-Secret 3/3, enter the door to the left from the lockers, knock out the staff member inside with your fists, go past the toilets into the shower cabin and break the cracked floor (picture 15).

Picture 15


Return to the corridor before the changing room. To access Weapon Part go to the left, and then turn to the first corridor on the right (picture 16). Walk that small corridor, turn right into another one with the glass door to an office at the end and an open window to a lab on the right close to you (picture 17). Be extra careful because the staff members can still spot you that far through that glass door! When they are not looking through the door, quickly sneak behind the pillar on the right and jump into the laboratory through the window and drop onto the table. Do not fall down into the green goo because you will die instantly. On one of the shelves, you will see a weapon part lying (picture 18). Carefully take it, and then return to the corridor you came from by jumping out through the same window. Now make sure the staff members are not watching through the glass door, and then quickly sneak back into the corridor with the door to the changing room.

Picture 16

Picture 18


The only thing left now is getting back to the elevator. Sneak past the corridor with windows on the right by hugging the left wall, so you don’t get spotted, and the stand at the corner right behind the corridor with the windows (picture 19). Now crawl under the windows hugging the left wall and then turn left to the elevator (picture 20). Use the keycard to call it, walk in and press the button inside to finish the mission. Congratulations! You’ve collected everything and visited all the hidden-not-secrets without being spotted!

1) For some reason the level is just called SinTEK Chemical Plant despite having a second part. It is likely that the second part was initially named differently, and later the developers simply forgot to change the mission’s title for the loading screen.

At the start of the level, among the laboratories there is a guard post you can visit. There is a hole in the staircase base you can crawl through to get some glowsticks.



After you drop down through the vent shaft to the lower level there will be a second weapon part in a locked room behind the glass. After you get access to the upper level, go to Lab 4 and take the blue keycard from the table there. After that you can unlock that room and take the weapon part along with some glowsticks.


Only accessible in no-clip. If you fly out of bounds near the level exit you can find a hidden Ocrana scull logo. Ocrana was a German esports club founded in 1996.



Incompletable. Even if you are lucky and eliminate all the guards before they reach the alarm, the farthest you can get without triggering it is up to the scientist in the U4 chamber. Unless there is some way to get to the upper level before that room, this objective is impossible to complete.



1) To pass through the laser corridor to the upper level after knocking out the scientist and taking their keycard, step into the corridor chamber right before the lasers and then interact with the scanner on the left. Once you reach the end of the corridor, do the same to open the door in front of you.

2) To get access to U4 samples and activate the elevator, read the name of the doctor from the computer in his office, then search his name in the terminal at the guard post (the one on the upper level after you drop through the vent shaft) to get the password for his computer.

After you crawl out of the sewers, there will be a few containers on the left. One of them is opened with ammo and armor inside.



This level has no secondary objectives.

1) Even though JC tells you to go stealthily, there is no objective for that on this mission. Still, it is possible to complete it without triggering the alarm but you must act quickly in the first half of the mission. Climb up the ladder to the left from the start of the mission, open the lid above you, shoot the enemies quickly (do not worry, the staff inside the checkpoint won’t hear the shots), and then jump into the bed of the passing truck, and hide there. After the truck stops crawl out and go to the right through the door into the checkpoint. Knock out all the staff members inside before they can trigger the alarm. Open Gate B through the terminal, and shortly after that there will be a door to another checkpoint on the right. Knock out all the staff inside before they hit the alarm as you did before and open Gate C through the terminal on the second floor. Now the tricky part comes. Behind the Gate C there is one guard walking left and right, and as soon as he hears you shooting, he will run to the right to hit the alarm. I recommend to come out to the checkpoint's balcony, jump onto the archway above Gate C, and quickly sniping that guard from there. Kill the remaining enemies and proceed to the next mission. Congratulations! You finished another mission without triggering the alarm!

In the room where a mutant leaps at you from the crate, there will be a lot of crates stacked upon each other and the elevator to the upper level. Ride the elevator up, and on the left you will see two planks connecting two crates just beneath the upper level's floor. Carefully drop onto them and climb under the catwalk to collect the third and final weapon part and assemble the Plasma Gun. Beware though, that the ammo for it is very scarce on the next levels, so I recommend saving it for tougher enemies. Another reminder: if you assemble the Plasma Gun in the first half of the game, you won't be able to do that in the second. Check the Mission 20: Underwater Pass – Part 1 section for more info.



After you install the remote modem (see Secondary Objectives), use the terminal in that room to open the safe. Take the documents from the inside and the secret must trigger shortly.



In the very first room with the turrets, there will be an opening to the room where the conveyor belt starts. Crawl through it and there will be some destructible crates with ammo and armor. I highly recommend turning off the turrets before getting this semi-secret though (see Hints).



In the first section with the turrets, after you ride the zigzag conveyor to another room, there will be a green screen terminal on the orange machinery. Interact with it to change the destination of the SinTEK shipment.



Throughout the level you will find several U4 containers, the first ones shortly after you ride the forklift into a big hall. The entire level is backtrackable, so just be attentive and shot the containers as you spot them. The objective will be ticked off shortly after the last crate is destroyed.



In the room where you disable the first section turrets, there will be a net link access point between the two servers. Interact with it to place the remote modem and the objective will be ticked off shortly. Now you can get access to Secret 2/2.



1) In the middle and the end of the level you will face some turrets shooting at you. They are invincible to your shots, so do not waste your ammo on them. Instead, hide behind the crates and the machinery to get to the terminals as soon as possible to deactivate them. The first terminal is located on the second floor after the zigzag conveyor belt ride. To avoid running up the stairs and getting unnecessary damage shoot the vent on one of the walls and crawl inside it (see the screenshot below). The second terminal is located close to the start of the second turret section, follow the wall on the right and you will see a door guarded by a turret. Run through it quickly, and there will be the second terminal on the second floor.

After you complete the third primary objective and will be at the other side of the security grid, there will be an open conveyor vent on the left. Crouch inside and you will find a passage into a small cave with a woman worshipping the logo of Ritual Entertainment - the developer of SiN.



This level has no secondary objectives.

1) The turrets in the security grid are protected by a forcefield. To cross it, simply crouch all the way to the door on the other side shooting the barrels and the panels on the right to complete the third primary objective.

This level has no secrets.

After you clear the first corridor, go to the left room from the start (Computer Center). After opening the door, the alarm will start, quickly kill the guards inside, turn off the alarm and prepare to fight two spider bots that will emerge from under the floor. One of the scientists will run and hide behind an interactable door while another one will stay near the computer panels. Make sure the latter one stays alive and interact with him after the fight is over. He will enter the password into a large screen terminal which will tick off the objective and unlock a bonus mission. The next level will be changed from Mission 13: Freeport Sewers – Part 1 to Mission 12 - Missile Silo.

1) After unlocking the security doors, the alarm enemy spawner in the first corridor becomes broken and starts spawning enemies infinitely. To fix it, go inside the computer center room, and quickly turn on and turn off the alarm.

2) Do waste your bullets on the two mini-boss biomechs before they start shooting you – they are invincible until that point.

This level has no secrets.

To get this objective pick up the walkie-talkie from the table on the second floor of the security tower before riding down the elevator. After going through the red-hand passcode door turn left and reach the next room where you hear the marines calling for you from under the floor, go down the ladder, destroy the wooden box that is placed on the hatch, interact with it and climb down. The objective will be ticked off after the dialogue.

1) At the end of the level you must act quickly to abort the missile launch. Two chaingun soldiers will be waiting for you at last terminal, to avoid receiving unnecessary damage shoot grenades or rockets into the manhole to kill them before climbing down the ladder. When you abort the launch through the terminal the system will require you to promptly enter the clearance code. Open the inventory menu (F11 by default) and cycle to the card that the military gave you when you rescued them. The password will be in the name of that card.

To get to the bonus level Mission 14: Freeport Aqueducts you have to fail the Find fastest route to Dam objective by falling down into the whirlpool closer to the end of the level. Check the Secondary Objectives for more info.



There will be a few bums at the start of the level. Simply ignore them and drop down to the sewers. The objective will be ticked off on the loading screen once the mission is finished. Unfortunately, it does not fail automatically if a bum is killed, so be sure to save at the start of the level, just in case.



This is where you will have to choose between the objective completion and a bonus level. Closer to the end of the level one of the supporting columns will be destroyed by the biomechs (if they somehow don’t do that, you can destroy it yourself), breaking the catwalk and causing a whirlpool in the water. Jump over the gap, open the door to the next room, climb up the ladder and proceed through a higher catwalk to reach the exit to Mission 15: Freeport Sewers – Part 2. If you fall down into the water, you will be sucked into the whirlpool down the pipe. The objective will be failed but you will get access to the Secret Exit to Mission 14: Freeport Aqueducts.

1) The locked hatches you find in the middle of the level are unopenable and have nothing behind them.

2) The Secret Exit is not in the black pit in front of you but in the red pipe to your left.

After you escape the rising water trap and jump into the stream again, you will see a broken ladder leading up to another catwalk in front of you. Climbing it is very tricky but possible. Align yourself with the ladder a few meters before it, then look up and hold W and Space at the same time. After a dozen of tries you should be able to grab the very bottom of it and stay in place. Slowly release the space bar and climb the ladder up holding the W. The secret will be behind the door with a few enemies and armor, ammo, and health pickups inside.



This level has no secondary objectives.

1) At the start of the level, after one of the enemies blows up the door valve, shoot the orange machinery on the left to blow it up and get the access to the maintenance vent.

This level has no secrets.

This level has no secondary objectives.

1) After you exit the sewers, beware of the snipers on the roofs at the dam entrance as they can easily kill you in one shot.

2) If you entered this level through Freeport Sewers – Part 1, the green door behind the wire gates near the dam entrance will be closed. The same applies for the sewer hatch if you came through Freeport Aqueducts.

There are two bananas lying on the roof of the checkpoint at the start of the level. To reach them, climb to the balcony where you get the sniper rifle, jump over the concrete elevation on the right, then on the Freeport Dam sign, and finally on the checkpoint's roof.

There are a few green barrels and two trucks located at the start and the end of the mission which are easy to spot. The level is entirely backtrackable, so just be attentive and shoot them on sight. The objective should be ticked off shortly once the last barrel is destroyed. WARNING! There seems to be a glitch where if a barrel/truck is destroyed by an enemy or an explosion not caused by you, it is not counted and the objective becomes impossible to complete. Make sure to save at the start and before the end of the level and shoot the barrels as soon as you see them.



1) The snipers in the beginning of this mission are wild and can easily kill you in one shot. Once you enter the level, go forward slowly looking back at the entrance and eliminate two snipers on top of it. Then run to the truck quickly, hide behind it and deal with the enemies on the ground. After that, slowly move back to the entrance peeking over the truck until you can shoot the sniper. After that you can go and pick up the Sniper Rifle from the balcony where the last sniper was.

2) The lower dam level after the elevator (see the screenshot below) is locked by a key which is impossible to get when you visit this level for the first time. To get access there, you must fail the primary objective on the Freeport Waterworks – Part 2 level. For more info, check the Mission 18: Freeport Waterworks – Part 2 section.

This level has no secrets.

This level has no secondary objectives.

1) You have to strictly follow the instructions for the objectives on this mission. For the first one, power off the clarifies through the red terminals inside the facility and then drain them in the courtyards by interacting with the valves on the tanks of the respective colors. For the third one, firstly turn off the pumps by interacting with the vales at the base of each pipe, and then close the valves at the top of them that are accessible from the higher catwalk. If you mix up the order, the machinery will blow up and the mission will be failed. The second objective can be completed at any moment though.

2) If you jump to the green area with some grey tanks to the right of the Sewage Intake entrance, you won’t be able to climb back due to the physics of Quake 2 engine and will get soft locked.

3) For some reason, the level is just called Freeport Waterworks despite having a second part. It is likely that the second part was initially named differently, and later the developers simply forgot to change the mission’s title for the loading screen.

If you got the candy bar from Hidden-Not-A-Secret 3/3 on Mission 6: SinTEK Chemical Plant now is the time to use it! Choose the bar in your inventory, come close to the boss, and press interact (not "inventory use") button while looking at it. The boss will take the candy and start eating it, sitting in place and ignoring you. This should give you enough time to severely damage or even kill it.



Here you will have to choose between accessing the locked area and completing the objective. For the former one, after you close the valves for the yellow waterway, a boss will emerge from the tunnel. Ignore JC's orders to close the rest of the valves and concentrate on killing the boss. After it dies, the primary objectives will be failed and you will get back to Freeport City Dam with the key to the locked area. You should finish the primary objective in 4 minutes, otherwise the mission will be failed. The area itself is not very interesting though. Simply run through the corridor to the dam's balcony and pick up the orange keycard from the table. Then return to the locked double doors, kill all the enemies inside, and turn off the turbines at the base of the room.

If you did not assemble Plasma Gun in the first half of the game, now there is a second chance to do that. In the room where you disable water circulation ports, there is a weapon part for lying on one of the shelves. If you did assemble it, the part (and all the parts on the subsequent levels) will be absent.



As you proceed through the base, you will find some machinery to blow up and disable. Because some of the spots may be unobvious, I will guide you through all of them one by one.

In the very first room there will be a few gas tanks to the right of the terminal.



Before diving down into the opened cargo door, proceed through the left door at the other side of the room to get to another room with a terminal. Use it to disable the water circulation ports.



As you swim through the underwater for the first time you will see a bunch of working machinery. One of them will be green color with a glass coverage; destroy it.



When you resurface for the first time, you will get into the room with the scuba gear equipment. There will be a few gas tanks standing on the shelf under a green pipe.



Much later in the level when you resurface for the second time, you will end up a room with two divers behind the glass and a closed door. There will be a gas tank on the pipe above that glass.



Shortly after the previous room, you will come into another one with an orange machinery and a gas tank attached to it. It is the last one but do not shoot it yet, as it will start the sealing sequence countdown (and be careful not to accidentally hit it, as there will be a biomech standing beside). Firstly, kill the biomech, proceed to the next room and disable the underwater security. After that shoot the gas tank and prepare to run back to room where you resurfaced. The objective should be ticked off as soon as you destroy the last machinery.

This level has no secrets.

This level has no secondary objectives.

In the area where you disable the first turret, look to the left of the upper platform: there are some bananas and chips lying on the ledge.



When you reach the Geothermal Station (see Secondary Objectives), there will be an elevator leading to Mission 23: Geothermal Plant – Part 1. Interact with the green scanner inside to activate it. WARNING! You will have to make a choice here. If you go through the Geothermal Plant and destroy it, the secret exit at Jungle Pass – Part 1 will become inaccessible. However, if you don't the secret exit at Mission 29: Containment Area 57 will become inaccessible instead. For more info check the Mission 26: Jungle Pass – Part 1 and the Mission 29: Containment Area 57 sections.



In the area where you disable the first turret turn back to the water you came from. Jump back and follow the underwater caves on the left; beware of the divers and the beasts lurking in the corners. After a short but relatively mazy section, you should surface to a small guard post with one enemy and health pickups. The objective will be ticked off once you reach it.

After you pass through the first turret section, there will be another one with a catwalk over the water. Kill the enemies but make sure not to hit the gas tanks and blow up the bridge! After that, turn off the turret, go through the door on the other side, quickly kill all the enemies and take the keycard to complete the second primary objective and return back to the turret terminal. Now, return back to the area where you disable the first turret, open the locked door and step inside a little (but not too far not to trigger the level change) to complete the third and final primary objective. After that, once again return to the second turret terminal, and now you can go for the rest secondary objectives. If you are not planning to visit Mission 25: Hidden Docks – Part 2, you can blow up the catwalk for the sake of it, otherwise I would recommend keeping it intact. Jump into the water and follow through a short cave to the door. Open it and resurface to a small guard post with one guard, some armor and Sniper Rifle ammo.



After you visited the Sniper Station, jump back into the water and swim to the door you came from. Open it and look up, there will a small passage right above it. Swim through it and you will surface at the entrance to the Geothermal Station. Inside there will be a biomech, some ammo, armor, and food pickups, as well as the Secret Exit.



1) After you follow the submarines into a bigger area and JC reconnects with you, do not go after them into the next room! If you do the door behind you will close and the enemies will spawn infinitely until you die.

2) In the same area mentioned above, do not surface from the water as there will be a turret and a rocket launcher soldier waiting for you. Instead swim through the door on the right, then through another door and surface in the next area (still beware of the divers, beasts, and the soldiers above), where you can climb up safely and disable the aforementioned turret. Also if you need to return back to the first turret terminal from the second half of the level, I would highly recommend jumping into water to this area to avoid unnecessary damage from the first turret.

Shortly after the beginning of the level you will see an elevator. Ride it up, come out to the third floor (yes, its the third by the level layot), and send it down. Then call it back again and crawl down under the bar and jump on top of the cabin just as it arrives. There you will see a ladder into a small room with an enemy and some health pickups inside.



2) I recommend activating this secret after you cleared the second floor which is accessed from under the pipes and got the keycard to the third one, otherwise the level becomes much harder to traverse. After stepping out of the elevator you will see some pipes and an area under them, climb down and press a lever then, then quickly climb up, go to the checkpoint room on the left from the ladder, and interact with the valve there. The pipes will blow up, and you can jump into one. This is tagged as a secret, however, there is nothing inside. Also be careful jumping out, because it is quite easy to get stuck in the debris below.



3) After returning from the Geothermal Plant – Part 2 via elevator, open the yellow keycard door in front of you, and follow the corridor to the first door on the right. Go inside and you will end up in a destroyed machinery lava cave. You can notice that the lava around the platform has solidified and you can go to a small cave on the other side. Inside you will find a mutant and a clip of plasma ammo.



This level has no secondary objectives.

1) You will achieve the third primary objective after the second part of this mission. To get there, destroy the vent on the third floor behind the room leading to the exit (see screenshot below). Beware of the rats inside the vent.



2) Second Visit. Due to a bug, once you complete the third primary objective, the previous two will reset and there is no way to re-complete them. So, unfortunately, you will see failed objectives on the loading screen. This does not affect the playthrough in any way though.

3) Second Visit. After you blew up Geothermal Plant – Part 2, you have a choice whether to visit Hidden Docks – Part 2 or go directly to the Jungle Pass – Part 1. For the former you have to return to the Hidden Docks – Part 1 via the elevator at the start of the level, swim back to the second turret section, and then run back to the regular exit there; if you didn't blow up the bridge there, it shouldn't be hard to do. For the latter, just proceed to regular exit on the third floor of this level.

After a few corridors you will enter the Siphon Control Room. Inside there will be a few pumps which you need to destroy. After they blow up and the floor becomes covered with muddy goo (don't worry, it does not damage you), the pass to the secret exit on Mission 29: Containment Area 57 will be unlocked. WARNING! Unlocking the secret exit for Mission 29: Containment Area 57 makes the regular walkthrough of that mission impossible; moreover, returning back to it after the bonus level breaks the main mission script, and you will have to use no-clip to proceed further. So, if you were planning to complete the game without using cheats, avoid blowing up the pumps!



There are a few health pickups hidden behind one of the pumps in the Siphon Control Room.



At the end of the level, once you get to the elevator leading back to Geothermal Plant – Part 1 there will be a few lockers in that room. There is another weapon part in one of them (unless you assembled Plasma Gun in the first half of the game).



When you come onto the catwalk above the first room where you blew up the generator, you will see a crack in the wall leading into a cave. It is a semi-secret exit that leads directly to Hidden-Not-A-Secret 1/1 at Geothermal Plant – Part 1. Unfortunately, due to a bug with the disappearing keycard (see Hints), you have to take the regular exit.



This level has no secondary objectives.

1) Even though you get a yellow keycard at this level, it disappears as soon as you return back to Geothermal Plant – Part 1. If you take the regular exit, you will end up in a room with another yellow keycard which lets you finish all objectives and get access to all the rooms. However, if you take the Secret Exit, the yellow door will be blocked and you will have to backtrack to Geothermal Plant – Part 2, to take the regular exit. It is not worth it since the Secret Exit leads to a hidden location at the Geothermal Plant – Part 1 which is accessible from the regular one anyway.

2) The music tends to break on this level after loading.

Closer to the end of the level, you will find a room with a staircase leading down. Follow it into the lower room, turn around and you will see a slightly lit panel behind the ladder. Interact with it and there will be some ammo and armor inside.

Return back to the upper floor, and go into the next room where you pick up the orange keycard. Now, make a save, just in case, then open the door making sure it doesn't damage you and crouch into the room without shooting. Just as you enter, there will be another interactable panel to the left of you; open it and there will be some ammo inside. The thing with stealth is that if you trigger the guards, the scientist standing near the panel will tuck into the corner blocking you the access to the secret. Of course, you can kill him but JC will chastise you for that.



In the same room as the previous secret, there will be another weapon part lying on one of the computer panels (unless you assembled Plasma Gun in the first half of the game).



In the very next room, after you destroy the navigation computer, you will see a catwalk with a med cabinet on the wall. Jump onto the crushed computer and then onto that catwalk. There will be another interactable panel to the right of the med cabinet with some ammo and armor inside.

Return to the room with the first secret and go through the door there. You will end up on a catwalk above the water. Dive down and you will see some pipes going into the caves. You can actually crawl through them and end up at a different starting point on Mission 26: Jungle Pass – Part 1.

This level has no secondary objectives.

1) To destroy the navigation computer, shoot the thick wires connecting it to the ceiling from the catwalk above the first turret room.

2) In the second turret room, you can pick up a glitched item among the other supplies. It is invisible, does not have a name and a picture, and cannot be used anywhere.

3) If you are taking the Secret Exit, don’t forget to interact with the orange keycard door to trigger the final primary objective.

Note: the level layout will be slightly different depending on whether or not you blew up the Geothermal Plant.

If you came from the Hidden Docks – Part 2 you will soon end up in the area with catwalk staircases above a small lake. If you came from Geothermal Plant – Part 1 turn left at the start of the mission and you will get to that area. Jump into the water and there will be some rocks on the left blocking the pass. Destroy them with the rocket launcher, swim inside, kill the beast, and swim up. You will find a small cave with a health pickup.

After as you reach Guard Station Gamma, there will be a weapon part along with some other goods on the rocks above and the station itself. To access them, return to the start of the jungle passage, turn around to the station and use the rocks on the left to climb up and jump onto the station and then on the rocks above. There will be some armor and ammo, as well as the third and final weapon part (unless you assembled Plasma Gun in the first half of the game).

After the Guard Station Gamma, you will traverse another passage with water or lava underneath you, depending on whether or not you blew up the Geothermal Plant. At the end of it, there will be a small guard post with ascending platforms. Kill the snipers and other enemies and get to the post. Turn around and use the left platform to go up, then jump onto the rocks in front and follow back to the start of the passage. There you will find a health pickup and, for some reason, the same weapon part you have already collected (unless you assembled Plasma Gun in the first half of the game).



If you didn't blow up the Geothermal Plant, there will be a water stream underneath the guard post mentioned in the hidden-not-a-secret 3/3. Jump down and then crawl into the small alcove at the end of the current. This will take you to the Jungle Pass – Part 2. I recommend visiting Guard Station Beta (it is just behind the door) beforehand, so you will have both primary objectives completed. If you did blow up the Geothermal Plant, there will be a lava pit instead of water. Even though the trigger is still technically down there, you will likely die in lava before you can touch it, unless you are playing on the easiest difficulty. From my personal tests, it is barely reachable on the max difficulty if you have 100% health and a spare Bio-Shield. And you likely won’t have that if you are playing on HardCorps. It is unreachable without a Bio-Shield even with 100% health and ammo.



This level has no secondary objectives.

1) Second Visit. Due to a bug, your primary objectives will reset after you return from the Jungle Pass – Part 2 even if the objectives menu has them ticked off. So, unfortunately, you will see failed objectives on the loading screen. This does not affect the playthrough in any way though.

At the very start of the level, after you climb out onto a small island, look around and you will see a log floating in the river. Use it to jump to the other side and you will find a small opening. Crawl through it and there will be a small cave with some ammo.



After you proceed through a small lake with two floating logs, you will go through a corridor with the logs rolling at you. After that, turn left and you will come onto a plane with a small cave at the other side. Jump onto the rock before the cave and there will be some ammo inside.

This secret feels more like a joke but is still counted. Later in the level, after you pass the concrete bridge, you will come onto a green platform above the canyon with some rocks on the right leading to a cave passage. Get to the cave passage and then carefully look to the left of it. You will see some bananas lying on the platform at the far end. To get there, you have to rocket jump from the very end of the rock you are standing on, so you land on the lighting pole and then drop onto the platform (the strafe running does not seem to work in this game, so don't bother with it). It may take some tries but it is possible. You will have to traverse the second half of the level again though, to get back to the jumping point.

This level has no secondary objectives.

1) On the island at the start of the level, walk onto the kneeling palm to make it fall and create a bridge to the other side of the river.

2) This level has a lot of traps, falling rocks, and rolling logs, so be extra careful while traversing,

Note: the level layout will be slightly different depending on whether or not you blew up the Geothermal Plant.

This level has no secrets.

This level has no secondary objectives.

1) Even though the game gives you an ATV, the vehicle control in this game is terrible, so it’s better to go on foot. Just be aware of the snipers at the third and the final outpost, and you will be fine.

2) The final primary objective has to be failed to progress through the story.

3) The music tends to break on this level after loading.

If you blew up the pumps on Mission 23: Geothermal Plant – Part 2, the second Darwin chamber will be drained and you will get access to the passage at the bottom. Jump down, open the three subsequent doors, and you will end up in a sort of a dumping bed. Make sure the claw above does not crush you, leap over the angled surface in front and get into the hole ahead to enter the Biomass Reclamation Center. Accessing the secret exit without blowing up the pumps on Mission 23: Geothermal Plant – Part 2 is impossible, since the goo damage is too high and you are stripped from all the items such as Bio-Shield. WARNING! Destroying the pipes on Mission 23: Geothermal Plant – Part 2 forces you to take the secret exit and makes the usual walkthrough of this level impossible; moreover, once you return from the bonus mission, the level script breaks and makes it impossible to complete it without using no-clip (see Hints).



This level has no secondary objectives.

1) Your HP will slowly drain while you are in the mutant form. Even though there is a lot of health pickups on your way, it is still better to act fast on this level, especially if you go for the Secret Exit.

2) Do not attack the yellow cyborgs while you are in the mutant form. Otherwise, you will trigger the security and won't be able to progress through the level.

3) While battling other mutants, aim at their heads to stun them, so they will attack you less.

4) Second Visit. You will return to the corridor that you could see from the start of mission but could not enter. Despite the previous mission, you still cannot attack the yellow cyborgs on this one. Gather the health pickups, open the door and proceed back to the Darwin chambers. Due to a bug, their opening order resets, however, even if you enter the first pipe, it won't drop you down again, soft-locking you. Since the second Darwin chamber is now considered complete and the objective is ticked off, go to the entrance to the third one and use no-clip (open the console with ~ and type /noclip, the same to turn no-clip off) to get inside. After that, proceed through the level as intended.

5) The underwater beasts in the last Darwin chamber spawn indefinitely, so just ignore them and swim straight to the exit.

6) After you return to human form, you can explore the rooms above the Darwin chambers and stack up on goods. However, the final door to the room with the Quantum Destabillizer is blocked by a cyborg (see the screenshots below), and there does not seem to be any way to move him except using no-clip, flying into the room, and making him switch to his attack state.

⠀
7) Second Visit. As funny as it is, even though the main level script breaks after you return, this is the only mission which does not reset your objectives on the second visit, and you can exit it with all of them ticked off.

Note: entering this mission breaks the main script for the previous one, and you will have to use no-clip to get over the soft-lock once you return.

Just after you climb out of the red mush on the other side, you will see some computers panels in front. Drop down and crouch under them, there will be an openable panel behind. Inside, you will find a small office with some health pickups and a board with developer jokes and references.

At the end of the level, where you need to activate the elevator, climb up on top of the ladder adjacent to it, and then leap onto some pipes behind. There will be another ladder with an openable panel on the left. Inside you will find some more health pickups.

This level has no secondary objectives.

1) Unlike the previous mission, the yellow cyborgs on this one will be aggressive to you, so get ready for a fight.

2) Just as in the previous mission, your HP continues to slowly drain, so you must act quickly. After dealing with the yellow cyborg and collecting the health pickups, climb up the ladder to a higher platform and press the big red button to stop the conveyor. Now, jump into the red mush pit the conveyor leads to. Beware that the machinery will re-activate once you get to the bottom, so cling to the left wall to evade it. You will emerge into a room with two grunts and Hidden-Not-A-Secret 1/2. Take the door on the left, pass through the corridor with more grunts and another cyborg, and you will get to the end of the level with Hidden-Not-A-Secret 2/2. To activate the exit elevator, press another big red button which starts the barrel transferring machinery. Climb up onto the elevator and tuck into a corner, so you won't accidentally get crushed by the machinery collision. Once the barrel is placed on the elevator, it will automatically go up returning you to Containment Area 57.

Shortly after the start of the level, you will enter a room with some lockers and a walkway up. Under the latter there is an interactable panel leading into the vent. Inside, there will be a few rats and an extra adrenaline.



As you enter the next room, look to your right and there will be three electric panels. The left one can be opened and leads to another vent with more rats, health pickups, and plasma ammo.



This secret is super weird: you do not get anything from it, it requires an adrenaline to access, and the trigger is located hanging in the air between the platforms. However, it is still counted, so I will give you step-by-step instructions how to get it without too much headache. Once you get to the final room of the mission, there will be a terminal with steep stairs and a door to the monster cage on the right (picture 1). Don't come close to the terminal and the stairs, as there is a trap on the floor which will teleport you directly into the cage! Instead, open the cage via the panel on the right, and carefully kill the monster from the outside. After doing that, make sure you haven't used the adrenaline collected in Secret 1/3; if you did, there is another one lying in this room on the operation table. Now, you can attempt climbing up the stairs. Their collision is quite wacky, but with enough effort you should be able to get into the corridor above.

Picture 1


Walk through the door at the end of the corridor and you will find yourself on the ledge above the first room of the level. There is a crane mechanism transporting the specimen containers from the top level to the bottom and then back (basically in a loop). Make a save file, so you won't have to climb all the way back if you fail, wait until the crane pulls out one of the lower containers and then drop onto it (picture 2). Now use the adrenaline, turn around back to the corridor you dropped from and prepare to make a tricky jump. The container will go up letting you access the platform above the corridor; the trigger, however, is located even higher in the air between the platforms that are not reachable even with the adrenaline active (picture 3). Jump into the trigger and you should technically be able to touch it with your head and then land on the platform above the corridor.

Picture 2


Picture 3


If the secret did not trigger but you still got onto that platform, crouch carefully to its ledge until about half of your body will be above the pit (picture 4). Jump up and land on the platforms above you, the secret must get triggered now (picture 5). If it still isn't, make another save file here and try to fall down between and slightly in front of the platforms to touch that pesky trigger area. If you triggered the secret and did not fall down to the bottom of the room, wait until the adrenaline runs out, crouch to the ledge of the platform and from there you should be able to drop back into the corridor you came from.

Picture 4


Picture 5


Congratulations! You got the most annoying and useless secret in the entire game!

This level has no secondary objectives.

1) The non-secret adrenaline intended for the third primary objective is lying on the operation table at the end of the level.

2) There are two interactable panels on this level with completely black screens. They do not seem do not much, however.

At the start of the level, you can see a mutant injection on top of a medical cabinet. It is barely reachable for grabbing with the interact button by jumping. Unlike on Mission 29, this mutant form only lasts 30 seconds, does not drain your health, increases your attack, makes you adrenaline fast and more resistant to enemy damage. However, you still cannot use any guns during this state.



Close to the start of the level, there is a prison chamber with a few mutants and two bosses spitting out acid. Kill all the enemies and then stand at the chamber's entrance. On the right you will see some ledges you can use to climb up. After that, you will end up on the ledge above the room adjacent to the chamber; look at the ledge on the other side and there will be an interactable panel leading into the vent. Walk the ledge around the room and open it. Inside you will find a Quantum Destabillizer.

Almost at the end of the level, you will find a room with a table and a big monitor. Climb up the obscure ladder on the wall and open the panel on the left. Inside there will be a few rats, and a rack with some health pickups and another adrenaline.



This level has no secondary objectives.

1) For some reason, one of the rats on this level spawns inside a door which prevents it from fully opening, so make sure to have an extra explosive not to get soft-locked.

In the hidden guard room, there is a locked door located on the ground floor. To get the key, go to the balcony of the room with a swaying exhibit and jump out of the long window outside (beware of the two snipers). The key will be on the ground to the right of the Bio-Shield. Now you can open the door. Inside, there will be an interactable camera monitor with an unusual surprise.

This level has no secondary objectives.

1) To get into the mansion without triggering the alarm, get into the hatch in the bushes to the right of the main entrance. It leads directly to the security room.

2) The Bio-Shield for the second primary objective is located to the left from the key for the locked door in the hidden guard room. (see Secrets).

3) To open the hidden guard room interact with one of the books in the cabinet on the first floor (see the screenshot below).



4) In the room that you access in the Hidden-Not-A-Secret 1/1 you can also find CD boxes titled WHY. Originally, they had a cover of Quake Mission Pack 1: Scourge of Armagon, which Ritual Entertainment (called Hipnotic Interactive back then) were the developers of. However, because Nightdive Studious did not have the rights to show id Software products, the easter egg was deleted in the SiN: Gold re-release.

At the end of the level, you will find a bed with a top coverage In Elexis's chamber. Climb to the top of that coverage via the cabinet, books, and the speaker and you will find another Bio-Shield there.



This level has no secondary objectives.

1) Beware of the snipers on the roof shooting you through the glass panels, as well as on the balcony outside.

2) To get to the terminal and subvert the security, interact with a tall book in the bookcase located at small circular staircase leading the large living room with glass panels (see the screenshot below). Ride the hidden elevator down, go through the stone corridor and there will be two grey doors at the end. Enter the one on the right, proceed through a small lake and you will find another door with a red stripe on it - the security terminal will be behind it. For some reason, this terminal sometimes gets buggy and either does not let you turn off the security or does not trigger the objective completion. I recommend getting there as soon as possible, avoiding being noticed by snipers and triggering the alarm. Also do not forget to save at the start of the level, just in case.



3) For some reason, turning off the security systems does not affect the lasers at the door to the Elexis's chamber, so prepare to fight some spider bots.

4) To open the level exit, press the button on the stairs railing at Elexis's chambers.
