Criteria: Kill 100 Specimens.

Start to play the game in beginner difficulty any map and you will get it soon once you will kill the 100th zombie.

Criteria: Cause a Specimen to Die by Luring them into Bloat Acid.

This should come naturally while playing as beginner. Bloats are such zombies which vomits acid. In each starting wave when you are captured by some other zombies a Bloat will come behind and it will try to vomit on you and for that reason the acid may fall on other zombies by whom you are surrounded and 1 will die. This can happen any time in other waves also.

Criteria: Kill 8 Specimens with One Grenade.

It is also a naturally obtainable achievement but yet at the very first wave lure the zombies taking knife at hand and when you will see a horde of them coming behind you throw a grenade pressing default key G. I will prefer the map WestLondon in beginner for this but can be done in any map.

Alternatively as commando spawn in the above subscribed map’s solo version and go to crawler zone and let some of those spawn standing at the circle and then throw a grenade on those.

Criteria: Kill 5 Halloween Specimens with any gun without reloading.

Reloading default is R. Never pressing this R, in the map HillbillyHorror in beginner difficulty kill any 5 zeds (zombies) by your default pistol or by any other gun and it will be done.

Criteria: Kill 15 XMas Clots, 5 xmas Stalkers, 5 XMas Crawlers, 1 XMas Siren and 1 XMas Bloat.

Xmas zombies are those which spawns in Xmas maps. I suggest play a short length game in beginner difficulty in IceCave / ThrillsChills map and before final wave you will get this achievement if you survive that far or any time before.

Criteria: Kill the Patriarch Before he has a Chance to Heal.

This can be done in many ways. But here I will write about the 2 easiest ways. To get these you will play a short game surely in beginner difficulty in any map. While final wave starting get a position quickly where the final boss Patriarch can come from only one way. You can play as demolition as your perk or as firebug. If you are playing as demolition then at the entrance of that 3 sides closed area place pipe bombs [default key 4] as many as you have at the entrance and when he steps on your pipe bombs it should be instant kill but you should fire on him at that same time / throw grenades. The other way is while you see him while playing as firebug throw grenades [G] on it while you are firing on it from your flame thrower at the same time not releasing the trigger. Being injured he will sit on the floor and continue throwing flame on him. (See: Ringmaster)

Criteria: Kill the "Ring Leader" (Circus Patriarch)

Play Lockheart’s Steamland in Objective mode or just normally in beginner difficulty. Do this achievement as part of "Straight Rush". I suggest to stand at the shop-door just opposite of the area where you had secured the 3 gold bars. (See: Golden 3 Crown Note)

Criteria: Kill 1,000 Specimens.

This will come naturally as you continue to play just killing 1K zombies. Yet you can go to the above subscribed map and kill there until 1k is not done.

Criteria: [2010 Xmas] Kill a Christmas Husk with any Pistol.

As sharpshooter play IceCave map at beginner difficulty a short length match and kill a husk [those zombies who throws fire]. However this can be achieved by using any other perk.

Criteria: [2010 Xmas] Kill the Christmas Patriarch.

When you will win in the map IceCave or any other Christmas map you will get it naturally by defeating the final wave.

Criteria: Give 1,000 Pounds to Teammates who have 50% of Your Cash or Less.

The custom map you have subscribed above that also have a co-op version. Start that with someone and there you will get unlimited money in spawning area. Press TAB to see how much you both have. Collect more than double of his money and give them 1000 by pressing B as default key.

Criteria: Kill 5 Circus Bloats in one game.

This will be done automatically as you will play Steamland in objective mode or even just normally. For them new players who still don’t know the specific names of different zombies, Bloats are those who vomits acid, slow moving, bulky body.

Criteria: Kill 3 Circus Clots in a wave with the Lever Action Rifle.

If you are playing as Sharpshooter you can buy it from shop or it may spawn at floor anywhere while you are playing Steamland. By it spam some fire on clots (the most ordinary slow moving zombies) and naturally 3 of those will die.

Criteria: [2010 Xmas] Kill 20 Christmas Clots in one wave.

In IceCave or any other Xmas map play in normal and it will be done solo once you finish the 3rd or 4th wave.

Criteria: Kill a Circus Gorefast with a Melee weapon.

While you are doing some of the above achievements I guess it is already done in Steamland when you had killed the dark reddish zombie with a sharp sword like weapon at its right arm. You need to kill it by using any melee weapon you have.

Criteria: In Co-op Mode, Use Syringe on Yourself 100 Times.

An extremely naturally done achievement once you heal yourself 100 times while playing co-op. Pressing default Q you can heal yourself. I got naturally but you can try it by setting a LISTEN server for at least 2 players or probably you already got it.

Criteria: Kill 1 specimen ONLY while expending a full M4 Assault Rifle magazine

In the above subscribed map as Commando buy a M4 rifle and kill a single clot or any other from full magazine. Then rest of the ammo of that magazine fire in the air not killing any zombie and reload [R].

Criteria: Aquire 5 Minutes of "Zed-Time".

Zed-Time is an event which happens when you get a 'Cool' kill. Such as a headshot, limb-removal, or absolute splatter of an opponent. It's random, so it will not happen every time, but headshots and such make it more common and that time you get in slow motion. You will get this achievement when summation of your all zed time will be equal with 300 seconds. So play on.

Criteria: Kill 6 Zeds with one magazine on an MKb42, without reloading.

At the above subscribed map play as Commando and buy a MKB42 and kill 6 clots not reloading. Very easy indeed.

Criteria: Kill 15 Specimens with a Fire Axe in a Single Wave.

As Berserker (Zerk) it’s a natural achievement. However can be done in the above subscribed map too by killing 15, but before you start killing let ‘em spawn at least 15.

Criteria: Kill a zed each with both the Bullpup and FN-Fal

In the above subscribed map spawn as Commando and buy a Bullpup and a FNFAL ACOG (FN-Fal). Now take some health of a zombie by Bullpup and then kill it by FN-Fal. I suggest to do it on scrake [zombie with a chainsaw].

Criteria: Finish off a Fleshpound using a Melee Attack.

In above subscribed map as Berserker take a melee weapon and kill a Fleshpound. (See: Have my axe)

Criteria: Kill 5 Circus Crawlers with a Bullpup in one wave.

While playing Steamland as Commando use Bullpup to kill 5 Crawlers [black spider like]. Yes 5 will spawn in a single wave sooner or later from 2nd wave.

Criteria: Kill 100 Sirens.

In the above subscribed map go to Sirens lane and there you may find a LAW beside it. Now killing 100 Sirens will take few seconds.

Criteria: Land the killing blow on a Circus Fleshpound with a Pistol.

I can’t perfectly remember where exactly I had done it but you can try it in the above subscribed map first. For this I will suggest you to play as commando such that you can see its health. First reduce its health to a minimum and then by a pistol take the head shot.

If it does not work there then try the same method in Mountain Pass map and it must work. And yes I suggest to do it in Beginner difficulty.

Criteria: Survive 10 seconds after being screamed at by a Circus Siren on Hard or above.

In Steamland while playing objective or normal map this will happen in some point if you can survive 10 seconds more after a Siren screams at you.

Criteria: Get 1000 points of burn damage with the MAC-10.

As Firebug go to the above subscribed map. Buy a MAC-10 and kill some zombies. You will get it soon.

Criteria: Kill 1000 Hillbilly Zeds.

As you will try HilibillyHorror map in various difficulties you should get it naturally. If not just play it in beginner difficulty & long games and kill 1K zombies and you will get it.

Criteria: Kill 4 Specimens with a Single Shot from a Hunting Shotgun.

As support specialist spawn at the above subscribed map and get a hunting shotgun or you may spawn with it if level 5 / 6. Kill 4 clots by 1 shot and you are done.

Criteria: Turn 5 Fleshpounds into Giblets.

Giblets are when you blow up an enemy and it turns into a fine red mist, or meaty chunks. But no real corpse left behind. So spawn as demolition to the above subscribed map and let spawn 5 Fleshpounds. Now get a M79 Launcher and right click to aim them and shoot from a little distance. After shooting 3 / 4 times you will be done.

Criteria: [2010 Xmas] Kill a Christmas Crawler with a Crossbow.

If you have not yet got it normally, then as sharpshooter start IceCave and get a crossbow and kill a crawler by it.

Criteria: Kill 200 Bloats.

Go to the above subscribed map. Stand at bloat zone circle and start to kill. When 200 will be done you will get it. Use flame thrower as firebug or shotguns as support specialist for faster kills.

Criteria: Obliterate 10 Zeds at once with the Pipe Bomb.

As demolition spawn at the above subscribed map and go to the crawler zone and let those spawn some. When there will be a lot of those, go in the zone and throw a pipe bomb and come out quickly. It should be hopefully done.

Criteria: Kill a zed that has injured a player (M7A3 rifle)

Spawn as field medic in the above subscribed map and get a M7A3. Let any zombie hit you and then you kill it by this.

Criteria: Kill a ZED with a direct (unexploded) shot from the Orca Bomb Propeller or the M-79/M32

As demolition spawn at the above subscribed map and kill a clot just by normal left click of M79 [no aiming by right click].

Criteria: [2010 Xmas] Kill 3 Christmas Zeds in 1 ZED time chain with a Melee weapon.

Another normally achieved achievement. In any Christmas map like IceCave when you get a 'cool' kill by any melee weapon, things happen in slow motion and while that slow motion is active, you need to kill more 2 zombies (preferably clots) within that where the 2nd kill also expected to be another 'cool' kill. I think if you are surrounded by clots then this may happen.

Criteria: As Firebug, kill the Husk with the Flamethrower before he hurts anyone.

This can be easily done in the above subscribed map. Play as firebug and let spawn a husk and avoid its fire and kill it by your flame thrower. If you are level 6 then you will have natural 100% resistance from fire damage of it.

Criteria: Kill 20 Stalkers with Explosives.

In the above subscribed map this will be done very easily. As demolition throw some pipe bomb or grenade to the stalkers after those spawns.

Criteria: [2010 Xmas] Get covered in Christmas Bloat Bile and live for 10 seconds on Hard, Suicidal, or Hell on Earth.

In any Christmas map like IceCave when you will play these higher difficulties may be this will happen at some point. If not, then in the initial wave in hard mode go near a blot and get vomited by it and heal and avoid other zombies. You will get it. Best perk I think as Berserker to do it as it has resistance from the bile.

Criteria: Kill 4 Circus Zeds in 1 ZED time chain with a Melee weapon.

See Deck the Halls with Buckets o' Blood above. This time do it in Steamland and for 4 instead of 3.

Criteria: Kill 10 Circus Clots with a Fire-based weapon.

You need to kill 10 clots in Steamland using any weapons which belongs to firebug perk. So, play as firebug at least the initial wave and you will be done. However, the default pistol is not countable for this.

Criteria: Deliver the Killing Blow to the Patriarch with a L.A.W. Rocket.

In the above subscribed map there exists Patriarch zone. Beside Serine zone you will get a LAW. Take that and kill the Patriarch with it. Best done as demolition I guess.

Criteria: [2010 Xmas] Kill the Christmas Scrake with a Fire-based weapon.

If you play any Christmas map like IceCave as firebug then it will happen. Play in beginner difficulty and kill a Scrake (chainsaw dude) by your any perk specific weapon.

Criteria: Push a scrake back with the direct fire from a Hunting Shotgun or alt fire from the Multi-Chamber ZED Thrower

As support specialist get a Hunting Shotgun in the above subscribed map. And kill a scrake. Don’t aim. By your fire it should go little back while dying at that moment and you will be done.

Criteria: Turn 500 Specimens into Giblets.

As demolition get a M79 in the above subscribed map. Then aim and shoot to clots / gorefast / stalkers / crawlers from a little distance. First let those spawn a lot. Once 500 kills are done you will be done too.

Criteria: Kill a Circus Scrake with a Crossbow.

As sharp shooter get a crossbow in Steamland preferably in beginner difficulty. When you will see a Scrake shoot at its head by the crossbow and it will die and you will be done.

Criteria: [2010 Xmas] Kill 3 Christmas Stalkers with a Lever Action Rifle without reloading.

In any Christmas map like IceCave play as sharpshooter and get a Lever Action Rifle. Even you may get it somewhere on the floor. Take it and when you see a stalker kill that by it and then don’t reload. For other kills switch to your other weapons immediately. When you see the 2nd stalker switch back to Lever Action and kill it and then switch to other weapon. Now after you kill the 3rd stalker by switching back to Lever Action you will be done. However, be careful about no reload between first and third kill.

Criteria: Kill 10,000 Specimens.

I will say not to bother about it. 10K kills will come naturally as you will play the game more and more. Alternatively go to the above subscribed map and while you will raise your different perks it will be done naturally with time. Kill any type of zombies and 10K in total.

Criteria: Kill 5 Hillbilly Zeds in 10 seconds with the Scythe or Axe

In the HillbillyHorror map as berserker in the beginner difficulty get an Axe. Then go close to the horde of clots / gorefasts / stalkers / crawlers and kill those rapidly as fast as you can. If the 5 kills are done within 10 seconds achievement should pop up.

Criteria: Kill a specimen with every shot from your Revolver for one magazine.

Spawn at the above subscribed map as sharpshooter and get a .44 Magnum. Now go to clot zone and start killing aiming at head. Never reload. You will get plenty of time to aim for each kill. If you miss a shot then reload and start from the beginning again. It’s not difficult.

Criteria: Kill 4 Stalkers in a game with the Vlad9000 Nailgun.

In the above subscribed map spawn as support specialist and get a Vlad the Impaler. Go to stalker zone and let 4 at least spawns there and kill those by it.

Criteria: Set 3 Hillbilly Gorefasts on fire with the Flare Pistol or Trench Gun

Play HillbillyHorror as firebug in beginner difficulty and in second round get a Trench gun and kill 3 gorefasts by it. Actually a natural type of achievement.

Criteria: Complete 10 Waves when the Rest of your Team has Died.

Yes complete total of 10 waves being alone. This is meant to be done in co-op games as I had done. May not be in a single game but in total. Yet just as experiment you can simply set a listen server and in server rule tab number of players as 1 and play a long game in any map in beginner difficulty. If you had won that game then I guess you should get this achievement after 10th wave or even before if you had any count already.

Criteria: Transit - Pick up the door key

Play Transit in objective mode and in beginner difficulty. During first wave you will be prompted to pick up door key. Do that and you will be done. So it’s a very natural achievement.

Criteria: As a Medic, Kill 8 Specimens using a Knife in a Single Wave.

In the above subscribed map spawn as field medic and let at least 8 clots spawn at a time. Then kill those using your default knife.

Criteria: Kill 4 different types of Zeds with headshots with 4 shots from the Long Musket or the M14 without reloading.

Spawn as sharp shooter in the above subscribed map. Get a M14 EBR shotgun. Now first go the scrake zone. Aim at its head carefully and kill it by a single head shot. If it does not die then reload and get another head shot. For every time you must reload but once it dies by the first head shot of the magazine no more reload. Then go to blots zone and kill one by head shot and then gorefast and a clot.

Criteria: Kill 12 clots with one magazine without reloading (MK23)

Spawn as sharp shooter in Mountain Pass map and play in beginner difficulty. After the initial wave buy a MK23 pistol and go to the road area where you will get enough space. Now whenever a clot will be near you shoot its head by that MK23 and after that switch to the other weapons for killing other type of zombies. Don’t reload for the MK23 ever. For certainty I will suggest not to reload any guns for this achievement. If you don’t even get 12 clots head shot in round 2 and you will be in shop but never reload your guns though you can buy ammo. In the next round same way kill clots by that M23 and this way when 12 perfect kills will be done by that full magazine you will get the achievement.

Criteria: Kill 20 crawlers in mid-air with the M79.

As demolition spawn at the above subscribed map. Get a M79 grenade launcher. Go to the crawlers zone and let those spawn. Notice that while those are spawning at the opposite wall those are falling from above. Aim your M79 at the middle position of that back wall and shoot. Those will die while falling down which means mid-air kill. Repeat it until you get the achievement.

Criteria: Heal others for 3000 points of health with the MP5 SMG

As Field Medic spawn in the above subscribed map and buy a MP5 SMG. Then go to the Medic Area and pressing middle mouse start to heal the “Fresh Meat”s. When 3K points will be done you will get this achievement. Another way is while you are playing Steamland in objective mode healing the Ringmaster also counts. For this dont kill the last clot and let it hit him and heal him.

Criteria: Protect the ringmaster during the defense mission so that he does not get hit more than 15 times.

As you are playing Steamland in objective mode and in beginner difficulty after reaching at the place opposite of a store entrance you need to keep alive ringmaster for some time. During this time stay very alert such that zombies can’t hit him. Yet if that happens and that hit count is not more than 15 times then you will get this achievement. I will suggest to stand just behind him and it’s a good position to look all sides of him.

Criteria: Kill 2 Scrakes with a Chainsaw in a Single Wave.

I suggest to play West London in beginner difficulty and a long game as Berserker. Around 3rd wave you will be able to buy a chainsaw and play on. After 5th wave there are chances to spawn 2 scrakes in a single wave. So you will get chance to kill both of those and achievement should popup.

Criteria: Kill 15 Hillbilly Crawlers in 1 game with the Tommy Gun or MKb42.

Play a medium length beginer difficulty game as commando in HillbillyHorror map and buy a MKb42. Whenever you see crawlers kill those by this gun and when 15 kills are done you will be done too.

Criteria: Decapitate a burning Halloween specimen in Bedlam.

Play Bedlam in Normal difficulty as firebug. Buy a Mac-10 at the beginning of 2nd wave. Now by that shoot a clot at its leg and then cut its head by a knife.

Criteria: Kill The Vampire Patriarch Ringmaster in Bedlam.

Actually it can be counted as a normal achievement but for ease play Bedlam a short and beginner difficulty game and when you will win the final wave by killing Patriarch you will get it.

Criteria: Kill 25 Burning Specimens with a Crossbow.

Play mountain pass in Normal difficulty. If you have perk sharpshooter in level 5 / 6 you will spawn with a cross bow. After the first wave when you are in the shop first change your perk as firebug and buy a Mac-10. But if you don’t have perks of sharpshooter of that level then first buy crossbow and then change your park as firebug and buy Mac-10.

Now with that Mac-10 shoot the zombies preferably at its legs and then by the cross bow try to get headshots and this way when 25 kills will be done the achievement will popup.

Criteria: Kill 1000 Specimens with the SCAR.

In the above subscribed map spawn as commando and buy a SCARMK17. Now kill 1K with it.

Criteria: Defeat the Patriarch on Suicidal.

If you win a game in suicidal or hell on earth difficulty then you will get this achievement. Alternatively in the above subscribed map you can try this and this will be far much easier.

Criteria: Heal 200 teammates with the MP7's medication dart.

In the above subscribed map spawn as field medic and buy a MP7M Medic Gun. Now go any of the medic area and heal fresh meats by that gun by clicking middle mouse.

Criteria: Kill 2 Circus Stalkers with a Melee weapon to the back in one wave.

Spawn as Berserker in mountain pass map. At the road area beside a trader’s shop there is a room. Wield the big door of that room. Now at the starting of 3rd wave stay beside the small door like this picture. Whatever will enter kill it from its back side and this way you will get 2 stalkers kill from their back side.

Criteria: [2010 Xmas] Kill 2 Christmas Gorefasts with a Melee weapon from behind in one wave.

See: Assistant Homicide.

Criteria: Turn 500 Zeds into Giblets using the M79.

In the above subscribed map spawn as demolition and get a M79. Go to the crawler zone and let those spawn a lot. Then from little distance aim and shoot at those. Just repeat this few times and you will be done.

Criteria: Kill 250 Halloween Specimens in Bedlam.

A straight forward and natural achievement as you play the Bedlam map in different difficulties this will come naturally.

Criteria: Hold dual 9mm, dual hand cannons and Dual Revolvers.

Play IceCave map as sharpshooter preferably in beginner difficulty. Buy duel 9mm, duel HCs, duel 44 Magnums (Revolvers). When the next wave will start you should get this achievement.

Criteria: Attach the crane hook within 125 seconds.

You will play Frightyard in objective mode and in beginner difficulty. There will be a time when you will be prompted to stand on an iron plate [crate job] on the floor. Yes, try this surely in solo and when you stand on the plate press F4 for third person view if needed and make sure that you never step off the plate. I got it in first chance but for you it may even take more than one chance, don’t give up.

Note: some says the crane takes 135 sec. But while i helped my friend she stood on the plate and she never step off the plate and got it in first chance.

Criteria: Kill the Patriarch when everyone is ONLY using Crossbows.

Play solo MountainPass in beginner difficulty and as sharp shooter a short game and kill the patriarch with cross bow. I suggest while the final wave stay near the L shaped area of the road where a trader shop and a room exists. There you will find a vehicle and stay hidden behind it. When Patriarch will come you may see it from far and aim at its head. You may be needed more than 1 shot.

Criteria: Kill a Hillbilly Husk and another Hillbilly Zed in the same shot with the Buzzsaw Bow or M99.

Play as sharpshooter the map HillbillyHorror a short match. Before 4th wave you must buy a M99 if not before. Now kill all but leave 1 husk and 2 / 3 clots. Now maintain a fair distance from those and try to get the husk and a clot at the same line of sight of M99. Once you get 2 of those, shoot. Once both the husk and a clot dies you should get this achievement.

Criteria: Hit a Scrake with the M203 Rifle grenade to kill him.

In the above subscribed map spawn as demolition and buy a M203. Let spawn a scrake and aim at its head and shoot.

Criteria: Kill a Circus Husk with a LAW.

In the above subscribed map spawn as demolition and get the LAW from beside serine zone. Then enter the husk area and let one spawn and kill it by this LAW.

Criteria: Kill 10 Halloween zeds in explosions using the Seeker 6 or the M32 within 5 seconds.

While playing Steamland in objective mode and in beginner difficulty you need to escort Ringmaster up to the point opposite of a shop. During this way try to protect him such that he does not get hit by any zombies preferably not more than 15 times. I suggest play as commando though not a criteria.

Criteria: Get into GLaDOS' core on Aperture.

Play Aperture map in beginner difficulty and as Berserker. There is a door which you need to un-wield and that will take very long time. So, to do this I had followed this…

https://www.youtube.com/watch?v=w7L3mtWeUrA
From the spawn point move forward and you will see a door at right side of it and go through it and then take left turn through stairs and take right and look left again. You will see a door and go through it to reach at that place. By the way… when the door will open enter that area and achievement should popup.

Criteria: Have 5 Breaker Boxes 100% repaired at the same time.

This is better to do with at least another player to make it easier just because boxes are 5 in number. In steamland play in objective mode and in beginner difficulty and in the 2nd stage you will be prompted to wield 5 boxes. Do those and don’t allow any zombie to break those. That second when the 5 boxes will be full wield the achievement should popup.

Criteria: Transit - Kill 250 Zeds before completing the welding objective.

Play Transit in beginner and objective mode. There will be a task to wield 2 boxes and you will see also about 250 bonus kill prompt. This phase will start just after the shopping. So I suggest to play as commando and keep 2 rifles with full ammo. Now standing by the side of the shop door start killing and if you can kill 250 then the achievement will be yours. You don’t need to start wield the boxes for this achievement. But be economical about the ammo consumption while killing 250.

Criteria: Drop 5 different Tier 2 weapons in one wave.

Play Abusement Park in beginner difficulty and as Berserker. When you will get enough money then buy one by one 5 Axe and drop those. This should be done in 1 shop time. However, you can drop any other tire 2 weapon playing as any perk.

Once you get that, spawn in the above subscribed map and you will find Z.E.D. gun on the floor just beside the wielding door. Take the gun and kill 20 clots. You can aim by right click and by middle mouse shoot. Once 20 kills are done you should get it.

Note: Though the Z.E.D. gun is available in that map always but I have doubt that this achievement will work or not except But It's All Red!.

Criteria: Heal yourself plus 5 other players with one grenade.

Spawn in the above subscribed map as field medic and go to one of the Medic Area and standing in the circle let spawns at least 5 (if not more) “FRESH MEAT”s and then from the circle go near them and you will start to lose health and quickly throw a bomb [G] near the feet and you should get this.

Criteria: Get all 3 gold bars without the carriers taking damage while they have them.

Play Steamland in objective mode and in beginner difficulty as Berserker and during the gold collection phase kill any other zombie except clots. If you are trying it solo then there will be 32 clots at a time in the map. However, you can neglect blots too as those walk slow. Make sure once you start carrying gold and until not this phase is finished nothing should touch you at all as some says this achievement is glitchy. Don't forget that if a siren screems and if you don't lose any health still the achievement may not popup. After all the golds are safe and you finished killing all the zeds and the phase is end only then the achievement will pop up.

Criteria: Transit - Get the Nitro to the Objective in 135 seconds or less.

While playing Transit in objective mode and in beginner difficulty you will be asked to carry Nitro to the objective area and during your way attacks will come and finally you will be needed to un-wield a door. Then enter there and go near the objective. You need to do all of these within 135 seconds to get this achievement. So from the start never stop, while killing always move forward.

Criteria: Kill 2 scrakes with one shot (M99).

In the above subscribed map as sharpshooter buy a M99 and go to the scrake zone and let several of those spawn. Then aim and shoot at head and this way you will get soon 2 scrakes kill by 1 shot.

Criteria: Get All of your Perks up to Level 5.

Keep your patience and besides playing the maps and various achievements as you progress, also raise all of your perks at least up to level 5 in the above subscribed map and you will get this probably longest awaited achievement.

Criteria: [2010 Xmas] Land the killing blow on a Christmas Fleshpound with a Knife.

If you are playing IceCave in beginner difficulty and as commando you can see the health of each zeds. When you see a fleshpound just reduce its health by gun shooting and then by your knife finish it.

Criteria: As Demolitions, kill 1000 Specimens with the Pipebomb.

As demolition spawn in the above subscribed map and go to the crawler zone. Let a lot of those spawn and go near those and throw a pipe bomb and immediately come out in some distance. Bomb will explode and some of those will die. Repeat until you get this achievement.

Criteria: Kill one of each type of zed in one round (HSG Shotgun).

Play KF-Office in beginner difficulty a long game and solo. Once you kill the Patriarch you should get it because he is the last type of zed. I hope that during the first 10 waves you will be able to kill all other type of zeds.

Criteria: Kill 15 Husks with the Husk Cannon.

As firebug spawn in the above subscribed map, buy a husk cannon and go to the husk zone. Now just kill 15 and you will be done.

Criteria: Get 25 headshots in a row with the EBR while using the Laser Sight.

As sharpshooter spawn in the above subscribed map and get one M14EBR. Now press middle mouse and laser sight should be active. You will see a red ray with a red dot at the end is coming out form the gun. Now go to clots zone and carefully place that red dot at its head BUT DON’T AIM. Now shoot and this way kill 25.

Criteria: [2010 Xmas] Kill a Christmas Siren with an undetonated LAW rocket.

Criteria: Kill 10 Specimens Feeding on Dead Teammates Corpses.

This achievement needs the presence of at least another player in the map. So start a co-op on any map and tell your partner to go away from you as far as possible. This is because he should be out of the sight of the zeds who are following you. He can be anything but you will be demolition. Start the game in beginner difficulty.

So during the first wave try to kill bloat / gorefast / stalker by your pistol. But avoid killing clot / crawler because clot and crawler are the specimens who eats the dead survivor. Now get surrounded by clots / crawlers and let them hit you. Since you are demolition so you will have pipe bombs and switch to one (default key 4). While your health is falling and when it reaches to 12 or 10 depending on by how many zeds are hitting you place pipe bomb at your feet position. You will die by their hitting immediately and while they will try to eat you the bomb should blast. Since other player is also in the map so even if 1 or 2 of those zeds dies that may add count for your achievement. After you die, tell your friend to do suicide. The game will auto take you both to the next map and do same there.

This achievement may take even 1 hour this way. It seems easy but it’s not that every map you do will add a count. Some will be simply 0 count. But don’t give up. The most important point is the timing when you place the pipe bomb at your feet position.

Criteria: Kill 25 Halloween Scrakes in Bedlam.

In Bedlam map you need to kill 25 scrakes. To do this you need to play that map several times or if you are playing those in various difficulties then it may be automatically done with the help of some luck.

Criteria: Use Bile or the Flamethrower to kill one of each Halloween Zed.

In HillbillyHorror map if u play as firebug and solo then this can be a normal achievement when you will finish the final wave. However I suggest for this a long game to be sure about spawn of all types of zeds.

https://sp.zhabite.com/sharedfiles/filedetails/?id=191617930

Criteria: Kill a Halloween Fleshpound and Scrake in the same explosion with the Seal Squeal Harpoon Bomber or the LAW.

I suggest to play HillbillyHorror in beginner difficulty and as demolition. And buy a LAW. When you will see a flesh pound don’t kill it but shoot a little and then stay in some distance from it not shooting any more and kill other zeds and when you see a scrake then finish all other zeds and let the scrake and the flesh pound chase you.. and when you will see those are in very close distance in between them charge a rocket from your LAW and hopefully they both should die.

Criteria: Kill 500 Zeds with the Schneidzekk Medic Gun while you are falling.

Play as field medic in MoonBase map in beginner difficulty long game(s). Buy a Schneidzekk Medic Gun and use it to kill all. Jump and you will feel low gravity and while you fall try to kill as many as possible and touching the floor jump again. This way you will get this achievement.

Criteria: Kill 30 Fleshpounds with the Dwarfs!? axe with back attacks.

In the above subscribed map you will get Dwarfs axe on the floor and play as Berserker. Now go to the fleshpound zone and let some spawn. When you will think they are at least 30 in number then take a side beside the front circle and whenever you will see those any turning back at you hit at its back. Try sometime and it will be done.

This achievement should work even if you don't have Gimli That Axe! .

Note: For help about different maps there exists seperate guides and its adviced to consult those as and when needed.

Tips #1

However, for any map I will give a simple tips, and you can experiment it if you wish. In any map where you will find a room with two-flapped-door, open it and throw granade to one plank to destry it. Now weild remaining one plank to 100%. The reson is zombies will come to that door and will try to break it rather than immediately attacking you, so you will get time to kill those relatively easier. However, you need to do this process in the begining of every wave as doors will be reset. See this picture for better understanding...


In the above picture, most zombies will come to the door and will try to break it standing there. But yet few may enter bypassing it. If the weilding is damaged then try to do it to back in 100% when you will get opportunity during the wave. In a co-op i guess this will be very helpful if properly done as I did.

Tips #2

Now I say you about another tricks. Do you have a partner who can solo HoE? If you have him he can help you the map achievements of all difficulties. Actually he can help 5 players for achievement at a time. But he must be the HOST. The steps are like this…

For any map and any difficulty join him all of you who needs achievement including he himself. Play the first 2 waves together. During shop time after 2nd wave and before 3rd wave starts you sell your weapons and give the host (who will solo from next) all of your money. Now exit your game and wait in steam. He got enough money and he will play solo now. He will say you to all of you to join once the final boss wave starts. Yes, join him once the final wave starts (not in shop time between 10 - Final). You will remain as spectator like a dead survivor. He will face and kill the final boss. If he can do it you both or all will get the achievement.

The advantage of this method is: from the 3rd wave as he will play solo so he will get less enemy with all less health which is easier to beat. But achievement will pop up for all the players who played first 2 waves and then quit. Also less time consuming.


I consider the following achievements are very naturaly obtainable achievements which will come as you will complete all the above maps. Yet in details...


You are expected to complete all the grindhouse and incendiary maps to get the above 4 achievements.

Grindhouse maps...

Crash

Criteria: Collect all the bile without a contamination.

I actually forgot to include this achievement but someone had pointed out me and so adding here. Thanks to him.

'Ex-scientist' achievement is earned on the KFO-Fright Yard map during Objective Mode. Specifically, it is unlocked in the fourth phase of the mission, where players must collect bile samples. To achieve this, you need to allow 10 Bloats to fall into the bile pit without any other ZEDs or players contaminating it.

So, the phases are as follows...
Phase 1: Holding them off
Phase 2: Searching for the Crane tools
Phase 3: Sitting on the pressure plate
Phase 4: Bile tanks
Next phases....

I think, to do it and not to get contamination best way is to play as Support Specialist than any other perks and in beginner difficulty. Commando is good too. A big no for Sharpshooter / Berserker / Medic. As Firebug mac-10 for enemies around bloats and flamethrower for groups that don't include bloats may work though but not ideal. The place is a pit and stairs are at both sides - so enemies will come from 2 sides. This phase will continue until done but you will try to do it fast such that you don't become out of ammo. Bloats will come to the pit and jump in automatically. Also, beware that if 3 zombies other than bloats go into the pit, the counter will reset (Don't Let Anything Else Fall In!) - specially careful about stalkers. If all goes right, the achievement should pop-up immediately after the phase. If not, complete the wave.

To write such a long informative guide may be there is any mistake. Sorry, for such inconvenience if any. I will update that part (if any) as soon as I will find out / notified about it. So feel free to comment as necessary. I hope this complete reference will be helpful for all the achievement hunters. Thanks to all.


Special thanks goes to my loving friend Khaleesi who first motivated me to play this game with her. I also give thanks to my all other friends who played with me from time to time and helped me to gain experience & achievements.


If you are a completionist, you may find it interesting...
