The demons came and the marines died. Except one. Your are the last defence against these hell-spawned hordes. Prepare for the most intense mutant-laden, blood-splattered action ever! The texture-mapped virtual world is so real, you don't just play DOOM - you live it.
DOOM is a great game, and to be honest doesn't look like it has aged a day (this could be due to Indie Games having lame "retro" artstyles but, whatever) due to the claymation, great physics, good AI and replay value.
Basically you shoot demons and play as a space marine... AWESOME!
