The player is in control of a prototype spacecraft (the "Hellbender") and must fly it around a map, destroying various targets and reaching checkpoints. The Hellbender has no inertia and thus cannot crash. There are ten weapons available. The Valkyrie and Laser cannons have unlimited ammo, but there are also dumbfire Sledgehammer rockets, homing Viper missiles, and devastating Doomsday mines. Many more weapons are available by collecting power-ups during gameplay.
