Yeah I think those sound files can be found in the L4D2 sound\music\mob folders.

I need to find the sound file when leave the saferoom

Hi Emily, this is a pretty good music pack, but I was wondering if you could add some additional music to this or maybe make it separate addons?

I was thinking you should add this song when you reach the saferoom with the survivors and this theme plays: Ju-On The Grudge - Results https://www.youtube.com/watch?v=qYNj8DJHD3g

And this timestamp theme in your video when you leave the saferoom would sound pretty good I think: https://youtu.be/HeI42ti64qk?t=262

Let me know what you think.

I make it into separated, go and pick one

It's too scary to actually use in a game. TwT
