The game takes place on the space outpost Terra-12. It was hit by cosmic radiation, which mutated most of the life forms on the outpost. The radiation was followed by a group of aliens lead by robotic \"governors\". As the half-human half-cyborg flying machine of the title, you are faced with many levels to clear of enemies. The gameplay is horizontally scrolling. Your unit is able to fly and then hold at a certain level in space. Defeated enemies often release gems, which can be collected towards power-ups. These include more powerful or multi-directional firing.
