Action shooter enthusiasts have spent countless nights poring over three episodes of the legendary computer game Doom. The time has come for a film adaptation to follow in the game's footsteps. A science team working on a remote outpost on the planet Mars has begun sending increasingly unpleasant messages to Earth. The results of the experiments are disturbing, the ranks of scientists are mysteriously thinning, and so the government has no choice but to isolate the base in the strictest quarantine and send a rapid response unit to Mars - elite marines armed to the teeth to find out what's happened and eliminate any threat.
At least that was the original plan. But the reality is beyond our worst imaginings. For the research team, through uncontrolled experimentation, has managed to literally open the gates to hell, from which have emerged hordes of horrific monsters that prowl the base's corridors, destroying all living things. Is there any human power to stop this horrible nightmare?
