Game Overview:  Two years following the unexplained disaster on Mars, the UAC returns to the abandoned facilities to investigate a mysterious beacon buried deep in the ruins of the ancient civilization. As a combat engineer, you fight for survival against an army of new demons and zombies, including Hell's own hunters. Use powerful new weapons like the classic double-barreled shotgun and the gravity defying "grabber," a device that can move, catch and throw objects or small enemies, as you battle through the onslaught of evil sent to hunt you down. Featuring new locations, puzzles and extraordinary powers like the ability to slow time, Resurrection of Evil will have players reloading for the bloodiest battle yet. The expansion pack also features multiplayer support for up to eight players covering five modes of play, including "Capture The Flag."
