Based on an updated version of the same engine technology used in Bungie's first person shooter "Halo," "Rebel Without a Pulse" puts players in control of a wisecracking zombie named Stubbs, "who takes on an ultra-modern city of the future using nothing but his own carcass and the weapons of his possessed enemies." The game is rife with tongue-in-cheek humor, a strong storyline and innovative combat techniques.
