This is a new music file to replace the music for the Carousel event in Dark Carnival, chapter 2 "Fairgrounds."
It is a modified version of the song "Amusement Park" from Cowboy Bebop, episode 20, "Pierrot le Fou," with the music sped up and the pitch shifted to make it creepier. If you're so inclined, you can hear the unmodified version here:
Includes both a VPK and a folder you can drop into your L4D2 directory. If you place the folder in your directory, PLEASE BACKUP YOUR ORIGINAL ROCKETRIDE.WAV FIRST. I am not responsible for replacing any overwritten sound files.
It has been tested in-game and does loop, but if you encounter looping problems, see the instructions in the rar.
