You are the only one who can save 28th century Earth from barbarians bent on taking over the planet. Your equipment? A sleek Turbo Sub that can fight under water and fly through the sky. Use your electro-plasma cannon to battle Stealth Raiders, mutant sea creatures and other enemies while avoiding obstacles such as pillars or explosive mines. You also have a limited number of mega-bombs that can be used to obliterate everything on the screen.

Submerge or climb at any time in your effort to clear each of the 17 levels. Gather gem pods to outfit your sub with upgraded technology, purchase extra ships or add to your fuel supply. While each player begins the game with eleven subs, you can receive additional crafts by running over Astro Foils. Link up with a second player to compete for the highest score. ~ Scott Alan Marriott, All Game Guide
