Hello KF2 community!
From time to time, again and again, I was looking for complete Killing Floor 2 soundtrack. As you know, the official score only contains 26 songs (out of what is currently around 150 songs).
Some songs can be found compressed on Youtube, or separately on various sites. However, there never was a full, complete score. Until now.

Because I love KF2 music (and quality music in general), I decided to make it.
Of course, it is Christmas 2021, and most likely, we will get new songs next year (which is good!). If that will be the case, I'll update this guide.
Q4/2022 update - We got some new songs, you will find them below.
Q2/2023 update - We got new song, you will find it below.
Q3/2023 update - We got new song, you will find it below.
Q2/2024 update - Found link to Itunes, containing Rocky Gray's music from KF2. I have attached it in the last section.
Also, due to human error, I may not have *all* the names described here (and if so, please let me know and I will update this guide - it is much easier for me when I get the number, and I just find it, rather then going through all files again and again).
However, I'm pretty sure that I have extracted all the actual songs from the game files (as of Summer 2023).
Q2/2025 update - added info and a link to vgmstream. Since Q2 2024 there were no new songs.

Complete soundtrack in .ogg is on Khinsider.

If you still want to do it yourself, one of the ways is described here. I would only add, that if you want to have the best possible quality from the game files, use vgmstream[github.com].
"Best audio quality from the game files" means, that the extracted files won't be additionally compressed via .ogg algorithm, as vgmstream exports into lossless .wav. However, please note, that the game files are already quite compressed, so this is essentially just a cosmetic gain.

To put it shortly:
1) You go to Steam\SteamApps\common\killingfloor2\KFGame\BrewedPC\WwiseAudio\Windows\
2) Grab them .wem files (bigger size = more likely its a song, and not just ambient sound)
3) Extract them .wem files with the software linked, ww2ogg & revorb
4) Use this guide you are reading right now to make sense of the numbers or B) if you want do it yourself
5) Go buy the official score to show support to creators! And go support Rocky Gray for his continuous work on KF2 music

1) You go to Steam\SteamApps\common\killingfloor2\KFGame\BrewedPC\WwiseAudio\Windows\
2) You find .txt files like WwiseDefaultBank_WW_MACT_Default.txt
3) You find the .wem number in these .txt files
4) You curse on the developers, because they don't use the same naming format for .txt files

MAMB - Trader music
MACT - Combat music
MSTG - Misc like player death

If you find any missing number, please let me know - I will update.
Also, if you know the author of some song where I did not write his name (because I did not know), also write me and I will credit them!
Due to character limitation in Steam Guide system, I had to divide this section into multiple parts.

I have opted for the following naming convention, as Khinsider only has the option to upload all songs without folders:

CM - Combat Music
TM - Trader Music
MT - Main Theme
BM - Boss Music
DJ HANS - Monster Ball music
Misc - Miscellaneous

460082005 = CM - Summer 2019 - Sigurd Johnk-Jensen - Infectious (Inst)

460082005 - Name of the .wem file

Big thanks to following people for helping me with this guide:

To Lith for her/his guide. This one helped me a lot, it was the starting point for me, as it was very good, but missing recent files.
Schiller for her/his Pastebin, which unfortunately expired early this year. Again, a lot of information there.

Thanks to Youtube channels of Iowa, Ammar, VGost - Video Game Soundtracks, Mugnum's alt and of course! zYnthetic Official . These channels helped me to find artist for songs I could not find them. Mugnum especially taught me some new ways of discovering artists name. Iowa filled a lot of the unknown songs.

And of course the original Reddit guide for files extraction, which I already linked above.

It took me a lot of time and I hope, it will now save yours.
I just cannot help myself, when I search for HQ music, I will not stop till I'm satisfied!.

Big thanks to creators of this great music! Apart from the official score, big thanks to:

• Rocky Gray
  
• Sigurd Johnk-Jensen
  
• zYnthetic
  
• and more!

You guys put effort in the music you make and it shows!
And yes, if TWI would complete the official score, that would be amazing!
Till then, go buy Rocky Gray's Music from KF2 on Itunes[music.apple.com]. It's missing some, but most of the songs are there, and in higher quality then gamerip ogg.

Thanks for reading!
