Research personnel are missing from the DBR Corporation, a clandestine laboratory funded by the government to conduct experiments on bio-engineered life forms. A team of special operatives is dispatched to the laboratory to investigate; what they find are brain-sucking zombies running wild in an experiment gone awry. You must rescue the DBR staff and fend off hordes of undead and other genetic mutations. Your high-powered hand gun will splatter these creatures, but you better shoot fast or they'll make you one of them! The game, a PC shooter with changing plot lines and varying scenarios, captures the realistic animation, resolution, and detail of the arcade hit. There's gore galore, and two-player mode lets you share in the carnage. The game takes care of your character's walking, so you can concentrate on aiming and shooting. The demo version terminates gameplay after a couple minutes, but you can play as many times as you want.
