WHAT'S THE STORY? Gory, fill-yer-pants frag fest set on Mars, then in Hell. Imagine the Aliens movie with demons and zombies. Or Halo with um...demons and zombies.

TECHNICALLY SPEAKING: A generic but visually stunning horror first-person shooter. This is the Xbox incarnation of last Xmas' PC version, by the way.

PLAYS LIKE? The original Doom, but for 2005.

WHO FOR? Sharpshooters. Gung-ho psychopaths. People with large collections of underpants.
