Techno for shooting games... Geometry wars, case in point.
Does anyone remember the music from Alien Trilogy? (ancient PS1/PC FPS) It had the most atmospheric minimal techno soundtrack ever, was truly beautiful, pretty sure I still have the soundtrack ripped on my hdd somewhere.
I'm a fan of rock and metal, but dear me is it used badly in games. Remember Prince of Persia: Warrior Within? Every time you were getting drawn into the atmosphere death vocals or power cords would rip you out of it and smash your head against the wall of anachronism.
