After years of infighting and millions of casualties, the 22nd Century sees the emergence of the New Earth, which is controlled by a Master Computer that houses government and information databases that are vital to the functioning of the entire planet. When aliens attack the Master Computer, the security of the entire world is in jeopardy. The only man who has the strength, intelligence, and courage to fight back against the alien horde is Nova, master of the ancient POWER BLADE. You'll take control of Nova as you enter the Control Center and with the help of the Power Blade take on a legion of aliens that are determined to destroy the planet. If you're able to survive level after level of attacking extraterrestrials, you just might be able to restore the Data Base and keep the New Earth safe.
