Nitro Planet

From the games packaging:

Nitro Planet... the very name conjures visions of monstrous alien beings, invaders, and pirates of a prehistoric planet made of heat and flame...Nitro Planet...your prison and, perhaps, cemetery. As the Nitro-men advance, however, you whip the laser out of your cloak and blast, firing a non-stop stream of death and obliterating the enemy into a million micro-particles.
