I like industrial music quite a bit (more back into metal lately though) and Nivek Ogre of Skinny Puppy is the first half. The second from Trent Reznor of NIN. He had done the soundtrack for one of the Doom games (I forget which, never really cared for Doom that much...too repetitive) and there was a Nailgun in the game as a weapon as sort of a tribute.
