Its More Human than Human by Rob Zombie
Thats just the way it starts off, I almost didn't uses the song because of the begining part with the moaning but the rest of the song worked great so I kept it in.
Its been a long time since I've seen a woodsball video. Notice how the very last few seconds of the film those 4 guys. The one guy gets hit and then right after that they slowley just start calling themselves out when they see one of their buddies leaving.
