All-action sci-fi adaptation of the popular first-person shooter computer game, starring The Rock and Karl Urban.

On the planet Mars, a team of scientists have set up an experimental research facility that suddenly ceases communication with no warning. A Rapid Response Tactical Squad, led by Sarge and Grimm, are dispatched to investigate, and make the shocking discovery that the scientists have opened a dimensional gateway to Hell itself.

Against all the odds, the squad have to fight their way through the base to shut off the portal, and then kill every horrific escaped demon creature before the hordes of Hell can reach Earth.
