Area 51

Your gear is strapped on, your gun is loaded and now you're ready to clean house. As soldiers in the Strategic Tactical Advanced Alien Response (S.T.A.A.R) Team, you have been trained to deal with this exact situation. Your assignment is to penetrate the security of the air base and eliminate all threat of the deadly alien infection that has spread throughout the base. You can't trust any base personnel - you must assume that all of them have been exposed to alien infection. Shoot anything that moves, but be careful not to hit other S.T.A.A.R Team members!
