The player must use an 8-way joystick to take control of a space astronaut named Exzisus with two buttons to make him fire shots at and drop missiles on enemies, and launch his bird and dog-like robots at them. There are also several different powerups that he can collect to aid him in his mission: L (Laser Light Blaster), D (Disruption or Destruction depending upon the palette), M (Missile), F (Full Automatic), A (Aerodynamic Power), O (Option), and, in some versions of the title, B (Barrier). When hit, Exzisus returns back to his regular humanoid form.
