Welcome to the planet Zombotron, inhabited by human-mutants or just stupid zombies. Nobody knows where they come from and what they eat. But we know one thing, they are ready to destroy everything that moves. During the colonization of the planet people built several laboratories to create bio-robots to clean the planet from evil, but something was wrong. There was no people on the planet Zombotron, but those laboratories still operate under the computer's control. You are one of the few bio-robots and so will you be able to complete this mission?
