KF2 Music Files List: WEM Numbers, Songs and Artists

The official Killing Floor 2 score contains only 26 songs out of roughly 150 in the game, so a fan compiled this list mapping each music file's .wem number to its real name, artist and event. It covers everything up to summer 2023 (no new songs were added through Q2 2025), and a complete .ogg rip of the soundtrack exists on Khinsider. To support the music, buy the official score and Rocky Gray's KF2 music on iTunes, which has most songs in higher quality than game rips. For replacing tracks yourself see custom music via Wwise; for the official OST see KF2 soundtrack.

How to extract the files

1. Go to Steam\SteamApps\common\killingfloor2\KFGame\BrewedPC\WwiseAudio\Windows\.
2. Grab the .wem files (bigger size means more likely a song rather than an ambient sound).
3. Extract them with ww2ogg and revorb, or with vgmstream for the best quality: vgmstream exports lossless .wav, so files are not recompressed to .ogg. The game's files are already quite compressed, so the gain is cosmetic.
4. Use this list to make sense of the numbers.

To find numbers mapped to real names yourself, open the .txt files in the same folder such as WwiseDefaultBank_WW_MACT_Default.txt (the developers did not use one naming format for them). Prefixes: MAMB is trader music, MACT is combat music and MSTG is miscellaneous such as player death.

Naming convention

Because Khinsider uploads all songs without folders, the list names tracks with the prefixes CM, TM, MT, BM, DJ HANS and Misc:

• CM: combat music
• TM: trader music
• MT: main theme
• BM: boss music
• DJ HANS: Monster Ball music
• Misc: miscellaneous

Example: 460082005 = CM - Summer 2019 - Sigurd Johnk-Jensen - Infectious (Inst) means file 460082005.wem, combat music, added in the Summer 2019 event, by Sigurd Johnk-Jensen, titled Infectious, instrumental.
