"The hard part for fans is going to be looking past expectations of what a DOOM game should be and embracing what DOOM 3 is -- a gritty take on the horrors of a demon infestation at a military base on Mars. There will be shooting aplenty, don't worry, and in the 10-minute demo there was quite a good deal of it, but none of it is at, say, the pace of Halo. Atmosphere is clearly being emphasized with heavy use of shadow and minimal lighting, plus six-channel Surround Sound with random ethereal voices crying for help and cackling voices from the shadows. It's creepy, it's moody, but when the action hits, DOOM 3 quickly kicks into high gear, slowing once more once all the corpses have dissipated."
