In this critically acclaimed action-horror re-telling of the original DOOM, players must battle their way through a demon-infested facility before entering the abyss to battle Hell's mightiest warrior - and put an end to the invasion
As one of only a few survivors, you must fight your way to hell and back against a horde of evil monsters.
The path is dark and dangerous, but you'll have an array of weapons--including a pistol, a chainsaw, grenades, and more--to use for protection.
