This is the track for when the Horde comes to attack you. I made this for a friend of mine, named OkyDooky, who happens to also be me (:D), who's creating a 2D adaptation/spinoff of Left 4 Dead called "Left 2Die" (2Die=2D :D) using the 001 Engine. It's going to be pretty good, but I'm not sure when I'll get the features necessary to complete it.
Anyways, it loops once then fades out. Enjoy! \m/
