You're a space marine armed with a mere pistol. Your mission is to locate more substantial firepower, blow your way through an onslaught of undead marines and mutant demons from hell, and navigate yourself off a radioactive moon base. In order to survive, not only do you have to make it through the first 27 blood-splattered levels of Doom, you also have to get through nine more incredibly tough expert levels in the all-new episode "Thy Flesh Consumed."

The shareware version contains the entire first episode of the game, Knee-Deep in the Dead. NOTE: This game has a native Windows version but it is recommended to use a third-party source port (see the links section below).
