Don't like Monstrosity and want Outbreak back? Well, there's a very easy solution to that. You don't need any special tools like Wwise or anything like that, nor do you need any knowledge on modding games either.

Go to your game's folder, more specifically here:

Steam\steamapps\common\killingfloor2\KFGame\BrewedPC\WwiseAudio\Windows\


You'll see language folders and a whole lotta WEM files with numbers for names. Those WEM files are the audio of the game, including the menu music.

So all you need to do is simply find the wem file corresponding to the old menu music - Pandemic Outbreak by Zynthetic and the wem file corresponding to the current menu music - Monstrosity by Rocky Gray.


If you can't tell from the image for some reason here are the number codes of the two songs that you'll want to rename/replace:

Outbreak - 799659999.wem
Monstrosity - 492841800.wem

And when you have the files you make a copy of the Outbreak wem file and rename it to have the name of the Monstrosity wem file and you're done! it'll just add it as a "name (2).wem" file so you'll have to get rid of the original and rename this one again lol


That's all you need to do to have the music changed when you start Killing Floor 2 next time around :)

I recommend keeping a back up of the Monstrosity wem file just in case you want it back without having to verify game files.

This will only affect the music when there are no events going on.
If you want to hear the outbreak song during holiday events you'll have to rename WEM files corresponding to those events, too.

I haven't bothered to get information on their numbers since i don't mind the music, plus it's only temporary, till the event lasts, but if you want you can have a look at text files in that same folder for information on event songs' numbers.

The text files are all called something along the lines of Wwise_DefaultBank_bla..bla.txt
