This game is a vertical scrolling shoot 'em up where the player controls a ship that has to shoot down alien ships. The enemies are Rava, Canda, Munda, Naga, Garda, and each one is worth a different amount of points. The first to appear are Rava, Canda, and Munda. They eventually break their formation & begin to attack. Naga & Garda eventually show up to join them. Canda & Munda start spinning wildly after the player shoots them once. Extra points are awarded for shooting them again & destroy them.
