They lay peacefully on the ground, riddled with bullets oozing blood onto the dry soil. The smell of fresh blood brings them back to life… sort of. Behold the zombie, and their weapon is hunger. Tearing through the death and decay, they aim to rip off your head and drink your blood. Command two robots with their own shooting methods. Choose which one to control, using different parameters and super attacks. Shooting monsters will help you upgrade your robot of choice. Face a giant boss at the end of each scene!
