The first thing we have to do is go to our game library, right click and touch properties


After that, we have to type -console in launch options

When we open the game the console will be in the menu then
Then we have to use the bind command, then we have to use a key that will help us open the console

in my case it is F8

For example:
bind "F8" toggleconsole


To open the console we have to touch the key that we have configured, again in my case it is F8

With this we will have the console ready to use

--------------------------------------------------------------------------------------------------------------------------------------

First you have to create a game in survival,select a campaign, select the map and after that change the server type to local server


Example:

When you are already in the game, you use the key that you used to configure the console (again in my case F8) and write

sv_cheats 1; noclip; sv_cheats 0

(This does not disable the achievements because sv_cheats will only activate the noclip and then turn off, even with that we will have the noclip)

After that, we will have to hide so that the special infected do not attack us

for example you can hide under the map or inside a building
although I recommend that you hide under the map in case a smoker catches you




you have to wait 10 minutes for them to count the medal, in case you don't get it, check the solutions tab




Remember: Your time will not be recorded but it will count in your achievements that you obtained a medal

---------------------------------------------------------------------------------------------------------------------------------------

This method is the one I used and it is the one I recommend if you are trying to obtain other achievements

you can kick the special infected with this command

bind Q "kick Boomer; kick (1)Boomer; kick Hunter; kick (1)Hunter; kick Smoker; kick (1)Smoker; kick Tank; kick (1)Tank; kick (2)Tank; kick (3)Tank"

This command does not need to have sv_cheats activated, since every time you touch the selected key it will eliminate the infected, In my case I have the letter Q


to reset this you have to go to Menu (ESC) / OPTIONS / Keyboard/Mouse / EDIT KEYS/BUTTON / Use Defaults

With this you will return everything to normal, although the bad thing is that you will have to reconfigure the key that will open the console

Although unfortunately it is not so effective, it will help a lot to get the medals
Although it is effective in expert campaign mode


-------------------------------------------------------------------------------------------------------------------------------------------

Here are other commands that can help you a lot (Extra)

sv_cheats 1; give pipe_bomb; sv_cheats 0

sv_cheats 1; give molotov; sv_cheats 0

sv_cheats 1; give first_aid_kit; sv_cheats 0

sv_cheats 1; give health; sv_cheats 0

sv_cheats 1; give ammo; sv_cheats 0

Mention that you can use these commands in survival mode but not in campaign mode,But they will help you a lot to get some achievements, for example, killing 5359 zombies


----------------------------------------------------------------------------------------------------------------------------------------

If you are trying to get the achievements that the campaign mode includes in expert and you want it to be a little easy

You can use the command to eliminate the infected in method 2
(which I already explained at the top of this guide)

bind Q "kick Boomer; kick (1)Boomer; kick Hunter; kick (1)Hunter; kick Smoker; kick (1)Smoker; kick Tank; kick (1)Tank; kick (2)Tank; kick (3)Tank"


If you are going to get this achievement, I recommend that you do not use the commands that give you things for example (pipebomb, molotov, health, ammo) otherwise you will not be able to deactivate the achievements

In short, you use the key that you configured to eliminate the infected, which in my case is Q, and also, a lot of patience and luck with those zombies



I still have to finish 2 campaigns in expert

------------------------------------------------------------------------------------------------------------------------------------------

1º When you reach 10 minutes in a survival game and you see in the achievements that the map did not appear, it is for 2 reasons

1) The first is because you selected the campaign and the map incorrectly.

For example, there are 2 the bridge maps and only one of them is included in the list of achievement maps



I say this from experience because I tried to get the medals on the bridge in the crash course campaign and it didn't work out, I tried the bridge in the blood harvest campaign and it did mark the map in the achievements, so I tell you I recommend that you read the maps well to get the medals






2) The second reason is because you broke the local server, I don't have much information on how to fix this, I guess you have to play survival for a while on an official dedicated server to fix that, I have no idea if this works



2º In case the achievements do not work for you in expert campaign mode (for example, I killed 5 zombies and it did not count in the counter for the achievement of killing 53K zombies) it is because you used a command that gives you things (Example Molotov,Pipebomb) ,I already explained that it does not work. you must use this type of commands, you can only use the command to eliminate the infected special that you already configured previously






so good luck with those achievements and luck surviving in the expert mode campaign ;)
