Most of the achievements work fine and have a discription that doesnt need more explaining.

But some of them are a different story. Hopefully this guide will help with those.

Easyer said than done because no endless maps has bosses. But some have champions that will be counted towards the achievement. The relevant maps are:

3 Forest of the Fallen
4 Bottomless Pit
8 Plateau of Decay
12 Wounded Crag

Tip: The steam overlay didnt update the progress of kills while in a round of endless for me - only after the round ended. The achievement itself did pop up while in a round of endless.

Those maps have around 1 champion per wave.
(You can relatively easy edit the amount to make your progress faster.)

How do i know this?
I had killed 59 bosses in endless. There had to be a way to do this. I was already "slightly enhancing my gaming experience" by playing around in the config data of the game (i dont understand most of it).
I found some data to the endless maps at the path ... Steamapps-common-deathtrap-cfg-map-endless-tier1. There are 13 numbered files for the 13 maps. The folder seems to contain lists of what has to spawn when and how (among the placement of traps and other). I just searched all of them for the soldier type champion and listed those. I also checked this in game.

Make progress faster by "modding"

As always: back up everything! your save file, the file you change etc. you will be changing the games own files - this might make your game unusable (if thats the case verify the games files through steam to restore the game to what it should be). (i accidentally broke the player character classes by changing something within the files for the enemies...)

You can easily edit the amount of champions spawning in these maps by just changing the counter from 1 to multiple.

Example for map 8:

SiegeWave[0].Group[6].Soldier[0].soldiertype=Army_Decontaminator_champ
SiegeWave[0].Group[6].Soldier[0].count=1
SiegeWave[0].Group[6].Soldier[0].customtime=1000.00

This makes 1 Decontaminator_champ spawn. Change to "count=10" and 10 will spawn.
I did this myself to make things faster and dont recommend the Decontaminator because of the poison pool they create. A different type of champion (on one of the other maps) would propably be a lot less hassle.

"Ink Mastery": You actually need more than Wave 20 in all endless maps. I went to 21 on a few maps and those didnt count towards the achievement.

You need to pass wave 22.

Same with "heroes in the storm". Play endless in multiplayer and the achievement will pop when you finished wave 32. (the picture of the achievement has a 20, the picture is misleading)

"Conservative Plan", "Master gunner", "Devils garden", "nearing perfection" and "a good start"

I unlocked these ages ago and cant confirm that the counter for them needs you to pass 2 waves higher than their description says, but i would guess that this is the case.

Finding someone to play with will propably not be easy. Finding 10 different people for some of the achievements will be even harder, if not impossible.


first try on getting them
"play with different players" (Common cause, On the dark side, defending champion)
I played with one friend. Some discussions said, that exiting the game and restarting would count towards the "play with different players" achievements. For us this didnt work.

Only after playing some versus games one of my counters for "Win against different players as attacker" suddenly was at 4 - without exiting the game between rounds. But we couldnt get this counter to go further, so i would consider this achievement bugged.

The counter for "Win 20 matches in Versus mode" (Paths of Glory) did not work properly. I won 10 games, the achievement counter says 4 (the in game counter for my wins does say 10) I would also consider this achievement as bugged - we gave up on it.

The other multiplayer achievements worked fine and without any problem.

second try

I did try the multiplayer achievements that didnt work before again.

We found out, that having "new pairings of characters" would make the counters on the achievements go highter - that way we both got all multiplayer achievements. But it does take a bunch of sufficiently high characters (have to be lv 11 to participate, but winning as defender could be hard).

Example: Player 1 has characters Bob and Anna; Player 2 just has Steve and Tom
Pairings: Bob + Steve, Bob + Tom, Anna + Bob, Anna + Tom all count as having played with a new player.

Paths of Glory needed to be "with new pairing".

Those would be easy - if they worked. All 3 got broken by an update ages ago and were never fixed.

With the current games version it is impossible to get these achievements.



But there is a way to get an old version of the game back - then the achievements will work.

Trying that way is completely on your own risk. Im just mentioning how i did it if someone already decided to try.

!Important!
I have no idea about programming. I just followed some tutorials and it worked.
Changing the games version comes with risks.

I took all of my saves from the current games version out of the save location and kept them saved somewhere else on my pc. Some people mentioned that the old version broke their newer saves. I started a new character to get the 3 achievements.

To get the old game files you need third party programs - one from microsoft (that should be safe) and one from github, the "depot downloader" (that i hoped would be safe, downloaded and scanned with malewarebytes)

The "depot downloader" will require you to input the name and password of a steam account that ownes deathtrap. Im sceptic to enter any passwort data into any program i dont know from a uploader i dont know. I did it in this case because the "depot downloader" seemed to be an established program and there were dozens of guides on how to use it and nobody mentioned any stolen passwords etc.. I dont know if this is actually safe, if you should change your password afterwards etc.
Nothing bad happened in my case.

I also recommend to only use the old game version to get the broken achievements and actually play/do the rest of achievements with the current version. There propably was a reason why the game got updated in the fist place...


Read all the instructions first before you piece them together and actually follow along!

In this steam discussion Larkin mentioned the way that worked for me:

https://steamhost.cn/steamcommunity_com/app/310510/discussions/0/1692659769954607561/?ctp=2#c4961229186478201188

His link to a guide on nexus (https://www.nexusmods.com/skyrimspecialedition/mods/32698/?tab=description) describes the process of getting old game files for skyrim - the instructions can be followed for any game you want.

I only used the nexus guide for some part of the process because the last part on how to use the cmd console was not clear enough for me.

Follow the nexus guide for:
- changing how steam will update the game.
- downloading and installing ".net" (no idea how it actually is called) from microsoft. I chose version 6.0 because the readme of the depot Downloader mentioned to work with 6.0 and didnt mention 7.0
- download and install the Depot Downloader

The next step is to use the depot downloader. For this i used a tutorial that showed the cmd environment and what to enter because the nexus guide just wasnt detailed enough for me.

I used this tutorial to see how things should actually look like (the video also uses a different game, just adjust accordingly):

https://www.youtube.com/watch?v=x_8KNOeLqyY

My cmd environment was black, not blue like the tutorial, but everything else was exactely like shown.

The correct numbers you need to retrive from steamDB are as follows (Larkin also mentioned the right ones in the discussion i mentioned above):

-app 310510 -depot 310511 -manifest 6213759715253176527

The download of the old game files was a little over 9GB for me and took some time.

The exchange to the old game files didnt take long.

After this you can launch the game and "paresan!" and "killing floor" should show progress. Jack of all trades" unlocked like it should.

After you have the achievements

Go back to the current game version by using steams "verify game files" option. Everything that doesnt match the current version on the steam servers should be exchanged for the files of the current version.
