A newly discovered alien temple on Mars has led to the UAC to send you there. You are the toughest marine that the UAC hired, and that is why you are on this mission.
What you find is disturbing. It seems that this is the place where most of your buddies went missing. Many familiar faces come to you.
The door closed behind you. And you are now stuck here until you find your way out.
