A massive demonic invasion has overwhelmed the Union Aerospace Corporation's Mars Research Facility, leaving only chaos and horror in its wake. As one of only a few survivors, you must fight your way to hell and back against a horde of evil monsters.

A cool horror game, good story and good gameplay feeling. I jumped in my chair at some moments. There is better horror games out there, ther is better FPS's with better stroyline out there, and there certainly is more active multiplayer out there. But this game is still worth a try. It's not at all like the previous Doom's, they were almost better.
