It is the year 2636. Once again the aliens who lost in battle to the Probotectors have regained their full strength and have begun a large-scale invasion. Humans are mere rag dolls in the face of the alien's overwhelming resources, scientific capability and powerful life force.
Six months later, two fighting robots, RD008 and RC011 the strongest Probotectors in history, appear in the devastated city controlled by the aliens.
A heated battle begins once more.
Super Probotector Alien Rebels is widely regarded as one of the very best action games on the Super Nintendo Entertainment System.
