Zombotron is a physics-based action platformer in which you play as a gun-wielding robot on a planet overrun by zombies and other creatures. Blast enemies with your gun, or blow them to bits with explosive barrels. Take the heads of your victims and collect coins along the way. You can purchase weapons, ammunition and other items at shop terminals located throughout levels. Your main objective is to reach the end of each level, and there are additional missions to provide you with a challenge.
