Soundscape Customization
Killing Floor 2 utilizes the Wwise audio engine, which is highly optimized but notoriously difficult to modify server-side. Unlike many Source engine games, you cannot simply upload an .mp3 to the server and have it play for everyone. Replacing music or sound effects requires a client-side interaction through the Steam Workshop.

1. Why Server-Side Audio Fails
The server does not “stream” audio to the client. Most audio is contained in local.wem files within the client’s game directory.
- If you modify a sound on the server, the client will still hear their local version unless they have the same modded file installed.
2. The Workshop Solution
The most effective way to implement custom music is via a Workshop Mod Collection:- Find or create a “Soundtrack Replacement” mod on the Steam Workshop.
- Add the mod’s ID to your server’s Workshop Synchronization list.
- When players join, they will be prompted to download the mod, ensuring that both the server and the client are playing the same audio cues.
