Story: 36 | Online: 5 | DLC: 6

You can accomplish this in one playthrough if you want. Or you can select a lower difficulty and enjoy the game at your own pace, worry and stress free. You can use this playthrough to get all the collectibles and other achievements, you can replay all the missions later for the Sniper Elite difficulty.

Follow the video guide for the location of gold bars and wine bottles. You can choose to do this in your first playthrough. Or if you want to enjoy the game without having to check the guide every few minutes, you can always replay the missions and pick them up later.

Find a friend and get all the online Overwatch co-op achievements. There are only 5 of these and it shouldn't take you too long, they are pretty straight forward. If you need a buddy, I'm sure you'll be able to find somebody by asking in Discussions.

In order for Steam to show full 100% you will need to separately purchase 3 DLC's (excluding Hitler) which will set you back around $15 ($10 on sale). They are not too hard but a little time consuming. I've included video guides for all of them. All the credit goes to Durexiq for making them.

Most of these are story related and cannot be missed. Some of them are part of missions and very hard to miss.

Front and Center
Get a scoped headshot over 150m


You should be getting this right away in Prologue. Just make sure to hit your target in the head (or eye for Deadeye).

Deadeye
Snipe an enemy through his eye


While you are here you might as well try to hit your target through the eye and get this over with. If you don't, you are bound to get this randomly at some point in the game.

Mousetrap Fuse
Use a trip mine to kill an enemy who is trying to assault your position


Also in Prologue, as a part of the tutorial, you will set up a trip mine that will kill an enemy and get you the achievement.

Trainee Sniper
Escape the German assault


Fuel Tank
Destroy a tank by sniping the fuel supply


You will find your first tank in Mission 2 - Schöneberg Convoy. Just destroy it by shooting it's fuel tank in the back of the tank.

Sniper Elite

You can do this in your first playthrough or later through mission select. Some useful tips: memorize enemy positions, go stealthy when you can, use cover all the time, use traps to cover your back, use grenades, don't rush and take your time! If you get stuck anywhere and need help, here is a playlist to guide you.

Make Every Bullet Count
Complete a level with 100% accuracy, using only rifles


After you finish the Prologue go back to mission select and start it again on Cadet. Make sure you skip the tutorial. Use only your rifle and don't miss (and don't get shot for Hide and Hope).

Hide and Hope
Complete a level without being shot a single time


Go for this one while getting Make Every Bullet Count. Simple - while not missing, also don't get shot. Use cover and take your time!

Double Dose
Snipe 2 people with one shot


You will have lots of opportunities for this but it can be done at the very beginning of Mission 2 - Schöneberg Convoy. After stealth killing the first guy, wait for the next 2 to line up and get them both.

Cooking Off
Snipe a grenade on an enemy's webbing from 100m


You will probably get this one randomly but in case you don't there is a spot in Mission 2 - Schöneberg Convoy near the beginning. Follow the video.

Get Off the Ground
Kill everyone in the convoy from ground level, except for Kreidl


In Mission 2 - Schöneberg Convoy, after you stop the convoy by shooting at the explosive. From this position ONLY kill your target - Kreidl, do not kill anyone else! After that, run down to the ground level and kill everybody else.

Fish Tank
Send the tank into the river by blowing up the bridge


In Mission 4 - Kaiser-Friedrich Museum, you will plant 2 explosives under the bridge and then go to a vantage point. Wait until the first tank is on the bridge and shoot the explosive.

Kilroy was Here
Make it through the tower to the winch room without being spotted


In Mission 7 - Tiergarten Flak Tower. Just follow the video for the best way to do this.

Pass the Buck
Get a sniped ricochet headshot


The best spot to get this is in Mission 8 - Karlshorst Command Post. See the video, it may take a few tries.

High and Mighty
Wipe out the Elite Russian Sniper Team from the rooftops


In Mission 9 - Kreuzberg Headquarters. Near the end of the mission, there is a cutscene in which you are getting sniped and end up going prone. There will be a total of 8 snipers to take down, just bait them until you see exactly where they are.

There is this excelent guide on YouTube to help you with this. You can do these in your normal playthrough or later through mission select.

Gold Rush
Find and retrieve all the stolen gold bars


Jungle Juice
Find and snipe all the hidden bottles throughout the game

You will get these over time, both story and co-op count. Some of them you will get in your normal playthrough while others will require a little bit of grinding.

Potato Masher
Kill 100 enemies with explosives


Make sure to use grenades and shoot at barrels whenever possible. Can easily be farmed by finding a checkpoint near a few enemies, nading them and restarting.
