Control a ship and shoot enemies while avoiding enemy fire. Power-up items appear when some enemies are destroyed. There are 3 items: Power-up (red), missile (green), bomber (blue). Defeat the target enemy at end of the stage to clear the stage. When all stages are cleared or all lives and credits reach zero the game is over.
