Something has gone wrong at a remote scientific research station on Mars. All research has ceased. Communication has failed. And the messages that do get through are less than comforting. It's a level 5 quarantine and the only souls allowed in or out are the Rapid Response Tactical Squad - hardened Marines armed to the teeth with enough firepower to neutralize the enemy...or so they think.

A group of UAC Marines respond to a distress call from a top secret scientific base on Phobos, a moon around Mars, only to discover it's been overrun by demons who seek to create Hell on Earth.
