Replaces the sound of a boomer's explosion with the Grunt Birthday Party 'YAAAAAAAAAY' sound. Originally found in the Halo series. It goes without saying, but I don't own this sound, or halo, or anything. Silly.
Ratings very much appreciated! This is my first mod, so any constructive criticism is also very welcome.
Special thanks to RiffRaff for helping me with the process and Youtube user unamed40 (L4Dmaps: Salem Hunter) for posting a video. Happy hunting!
