Three high-thickness sub-atomic laser safeguards are put with regard to the laser gun. Every last one of them houses an additional gun.

The player controls a robot protector inside the laser cannon. In the event that the laser gun is annihilated, the robot will be left unprotected. The robot can enter with another laser gun housed in one of the safeguards. When the new laser cannon is dynamic, the safeguard is no more. When the three safeguards are gone, the Savage Monstroth will come down to chase the player's cannon and robot.
The player wins a fight while obliterating all foe robots and guns on the screen. A fight is lost when the player's robot is obliterated. The main side wins ten fights and wins the conflict.
