You are in command of a Mark XIV intergalactic starcruiser in an uncharted quadrant of outer space. You land on a mysterious planet riddled with a subterranean maze of tunnels and caverns inhabited by savage Electrosauri whose horns generate electro-molecular charges capable of disintegrating you and your crew. Your photon ray pistol is activated by the joystick and the fire button. The iridescent eyes of the electrosauri light the cavern walls with eerie flashes as they stalk you, their horns crackling and sizzling. If even one blast of electro-molecular energy strikes you, your skeleton will glow inside your body as the bio-molecular compounds of your body disintegrate. WARNING: Beware the savage attack of the shaggy marsupods.
