Corruption by Kevin MacLeod
Formerly titled "Tyranid Battle Loop", this piece was written for down and dirty... and very very long battle scenes for space bug critters. But you can use it for anything you like! Got a video where you stuck a cucumber on a drone to terrorize your cat? Boom! Corruption. Or those really gross films of people removing cysts? ug. don't use this for that. Actually, why are you posting that? Don't do it. Just... ug. can't unsee... You can download this in uncompressed format here. Download comes with individual tracks so you can make your own mixes.
