Quake Legacy - Stroggin' around

Shivers... :)
That was Sonic Mayhem's Quad Machine track. That's also the heavy stuff I like to listen to when I play Quake Wars, Winamp running in the background, running a medley of Quake II 's and Quake II: Ground Zero's OSTs.

EDIT: let's just have another one, shall we? It's called Descent into Cerberon.
