In this guide, we will guide you so that you do not have problems with 100% of this game.
Achievements that are complicated or impossible if you try it in the normal way, but easier if you take advantage of mutators and correct commands that the game gives you (likeother source games)

This guide is separated into 5 sections, which each one, we give information and the methods to obtain each achievement.

You should be aware of something about the game before playing it, if you want to get the 100%, you must have at least 6 friends/players to obtain the most annoying achievement, also another achievement that requires 500 kills when +6 players are in the same server.

There are 2 more achievements that require completing each mode with 8 players but is possible if you play with some friends and random people.

With this mutator makes trivial the objective mode, unfortunately you have to win in the traditional way. At least you have high speed and enemies don't deal damage.

I strongly recommend completing objectives with friends, to reduce stress and time in some maps.

In this third part, we will focus on all the achievements related to farming zombie kills with weapons, both melee, and fire. Also of some miscellaneous achievements can be obtained this way.

Keep in mind that this method is the fastest possible, considering how difficult it is to get weapons or kill with certain weapons and that it would take a good amount of hours to achieve it.

You will also be able to obtain the achievement "The Manhattan Project", which is practically impossible if you tried it traditionally.

Like all source games, these achievements can be unlocked/cheesed easily, thanks to a custom map that is available in the workshop.

Link to the workshop map. Click on it, then subscribe and that's it.

The map is divided into 3 sections, where each one is oriented to certain specific achievements.

Even the map when entering, explains simply way about each one, it will also be explained in this guide.



The first zone will help us to get the achievement that requires the greatest grinding in the game, and that all it requires is to press the button that is in the room and wait (when leaving the zone it will stop advancing the kills).

In less than 2 hours of grinding, we will get the achievement.



In the second area, it is focused on 2 specific achievements of the arc, that playing it would be very difficult to obtain those achievements.

The first achievement requires shooting the watermelon from a certain distance.

The second achievement is to shoot the giant zombie and manage to kill it.

And in the last area, we have the farm of kills with all the existing weapons of the game, whether they are ranged or melee.

Keep in mind that the next weapon, which is the bow, is available in the second area, as well as its ammunition, so you will have to carry that weapon once we complete the two achievements related to the remote bow.

We will also have the grenades (Molotov, C4, and the grenade) available.

The pit is made for throwing grenades, while the side spawn is for weapons.

Next, the whole list of achievements that you can obtain in this area (it is long)




You have to use "V" (push) to use your bayonet against the zombies.


You have to do it in the pit.


You have to do it in the pit.

On your left you will see an area where you get infected if you enter that place, there you can obtain this simple achievement that requires taking the pills 4 times while being infected.

If you don't get infected in that place, try to change the difficulty to Nightmare.

In this fourth part, we will have the achievements that we can do alone or playing casually, it does not pose any challenge, some of them can be obtained with the help of the command and also with the help of the Achievement Map. Then the following achievements are:


You'll find grenades while completing objectives or survivals, there are some areas that spawn it or national guards drop it randomly. If you have the mutator activated, lure enough zombies to throw the grenade and kill yourself.


An achievement that you will easily obtain in hours, both playing casually and farming weapons on the workshop map. Try to hit or shoot the head.


This achievement can be easily done in the Achievement Map.



It will come out easily after several casual games or while advancing the other achievements of the game.


Seems that you have to attack a few times some zombies and move around the zone (close to fema crates) until the % appear, wait until 48-49% and throw a FEMA bag in the orange ramp, repeat until the achievement pops (You have enough bags to get it in one session).

For this achievement, you have to commit suicide with a firearm, when we are infected, for that we have to let a zombie bite us and we free ourselves with the V key (to push the zombies) and wait for it to give us the symptoms, If the screen gets a little blurry with dark-colored veins, we have to press the K key, which will cause our character to point and then we left click to shoot and thus we unlock the achievement.


If you have a weapon with a full magazine, you just have to keep the letter "R" until the animation of your character comes out checking the magazine and says his phrase (Totally full / Full magazine).


An easy achievement that is obtained in survival mode on casual difficulty, both in multiplayer and single-player it is possible to obtain it, you must be infected by a zombie and achieve a respawn token that is obtained after killing 10 zombies.

The fastest way to know if you are infected, is that you can use the pills.

Remember that at the end of each round, you lose the infection effect and you will have to do it again.


For this achievement, we have to join a group of them, either in discord or steam, once inside, when entering the game, we already win the achievement.

Update 1.12 (OCT 31)


Workshop Map: Subscribe the map, then join the map "nmo_melon_felon". Wait until the round starts, grab the melon and go to the exit door.

In this last section, all the achievements that are related to online matches, most of them aren't complicated at all, except one that is considered the most difficult achievement from the game called "We got this", which is difficult if you try it traditionally, but easier using the fastest method.


Self-explanatory achievement, both achievements require that 8 players have to survive/escape from each mode (objective and survival). It is advisable to play with friends to make easier the achievements, also don’t leave behind your other teammates.

Note: You must escape with your teammates in the normal way. Using the mutator makes trivial the gameplay.

The best maps for these achievements:

• Objective - Broadway: Short map with easy missions, last mission requires a code.
  
• Survival - Northway: No escape required, you only have to close the six doors in the last round.

Self-explanatory achievement, you have to save your ally when a zombie is grabbing him, kill the zombie before it bites your teammate.


Self-explanatory achievement, you have to kill 500 zombies when +6 persons are connected in the same server. It will pop up after several games.

Note: You can farm it easily if you or your friend can host a server in "aachievement"(grind map). It might take a few seconds in the "Manhattan" room.


This achievement requires that you have to kill an infected teammate before it kills him, the easiest way to obtain it is with a friend who gets infected by a zombie.

Note: Try to kill your ally with a gun, shoot in the chest if you are having issues with the achievement.

You naturally obtain this achievement if you play casual matches with randoms/friends, be aware of your team.


Undoubtedly, this is the hardest achievement, which requires that we have to beat 6 maps (check the description) with 6 or more survivors without dying or losing a single area. The first step to obtaining it most quickly possible is creating a server to play with your friends.

This link will help you to create a server:

When you managed to create your server and your 5 friends are on the server, you can continue. The fastest way to obtain the achievement is using a mutator that makes trivial the survival. This method you can easily get it in about 15-20 minutes.

This mutator from workshop:

It will be one of the last achievements you obtain in the game, after completing most of them.
