Z.A.R. is used by humans as a base for operating space production factories which manufacture space rockets, robots, and artificial satellites used to help expand to other galaxies. An error in the computer networking system has resulted in complete loss of control and has turned Z.A.R. into a factory producing deadly robots. You play Colonel Hermit, who has been equipped with a limited supply of weapons and has been sent by spaceship to Z.A.R. to restore order.
You can blow up everything around you (even terrain), destroy deadly enemies, jump up to 30 meters, shoot with a variety of weapons (including plasma gun, machine gun, cannon, rocket launcher), and more.
