One of the more "basic" Doom Clones—to the point that the first weapon of the game shares the exact same recoil pattern as the Doom pistol. It is, essentially, Doom's arsenal re-skinned, and many of its enemies mirror those in Doom itself.

Which, well, is fun as long as the levels are well designed. And, for the most part, they are.

The less said about the last two episodes the better, however—4 and 5 were so much trouble they made me question whether I was just burnt out on FPS games.
