Set in the year 2003, the game involves using a spaceship to destroy enemy droid ships. The player's ship is controlled using a spinner to rotate the ship's direction, a button for thrusting, and a button for firing lasers. The enemies that the player must destroy or avoid are drone ships, commander ships, two types of space mines, and shooting star ships.
