Play as a man trapped inside a dungeon-like tomb fighting for his life against a number of different kinds of enemies. From blob-spawning monsters, to armored men, to ghosts and even cyclops, you will have to earn your way through with different upgrades to either of your weapons. Falling sand surrounds you on all sides, making your only escape a blaster in one hand, and a grenade launcher in the other.
