The year is 2122 and you as the last star pilot must destroy each of the stars by using your plasma cannon mounted on the front of your space craft. While you're trying to destroy the stars one to five Alien space ships (Depending on level) try to crash into you, thus destroying one of your three lives. Unfortunately, you are unable to destroy these space ships because they have a special cloaking device which makes it impossible to hit them. The only thing that can be done is to avoid them. There are also different types of ore and minerals that can be picked up for valuable points. They are D-Diamonds, P-Plutonium, G-Gold, and S-Silver. These will appear randomly on the screen as the game progresses.
    The game uses the Atari's character set to draw the space ships. These ships are poked onto the screen and then moved around through poking new positions. The ship moves with the joystick and fires by pushing the red button. The game takes about a minute to intialize as it randomly plots the different stars. Remember don't touch the stars.
