STRAFE: Millennium Edition

STRAFE is a roguelike first-person shooter pushing the limits of computer-generated photorealism and hardcore sci-fi action into unimaginable territory.
FACE MELTING SPEED! The blazing fast action will hit you like the blast wave of a 50 megaton thermonuclear warhead, liquefying your skin cells and rupturing your internal organs. Yet still leave you coming back for more. 
PERMANENT DAMAGE AND GIBS! ÜBER-GORE technology means enemies explode with near never-ending fountains of blood, which never fades away. Create wicked works of death art that mark your explored territory from the unventured. 
ENDLESS CHANGING LEVELS! Randomly-generated levels are always different and violently unpredictable. Rooms, enemies, power ups, monster closets, and secrets move around every time you die and die and die and die!
