This is a side-scrolling shooter where you take the controls of a powerful spaceship and launch an assault on an alien world. The game requires you to navigate through caverns, metallic corridors, and open space while facing mobile and stationary enemies. Your ship is armed with a laser gun capable of firing in four directions. Using the aim button, you can fire straight ahead, directly behind your ship, above and below your ship, or you can launch four lasers that move diagonally from your ship. When certain enemies and inanimate objects explode, they release power-up icons. "S" icons boost your ship's shield power."P" icons increase power to your ship's guns. "B" icons cause a powerful bomb to explode, eliminating all onscreen enemies.
