Go through a mansion filled with zombies, chainsaw-wielding undead and other creatures. You must destroy their evil creator, Dr. Curien, while saving scientists and your girlfriend.

Your mission is to investigate the status of the mysteriously missing personnel at a genetic engineering center (The DBR Corporation) and of the first team of operatives sent to rescue them. You will also need to take defensive action and assist any survivors. During the mission, you will discover that the mad scientist Dr. Curien is the one resurecting the undead and you must stop him and his evil undead minions.
