SOMETHING WAS TERRIBLY WRONG IN the distant man-made Spondylus Solar System. One by one the planets' central life support computers had been infected with a life-threatening virus while the planet surfaces had been overrun with giant computerized dinosaurs known as Robosaurs. Under attack in his laboratory on Alpha Planet, Professor Proteus, the mastermind of the Spondylus System and founder of the Robosaur project suddenly realized that this deadly sabotage could only be the work of his former partner, the deranged Dr. Brainius. Years earlier, the doctor had fled Alpha Planet after Professor Proteus had exposed him for performing forbidden robotic experiments on human subjects. At last, he had returned to seek his revenge using the Professor's own creations! But, little did he realize that Proteus had been hard at work for the past few years perfecting the ultimate robosaur, Cyborasaurus.

There was only one hope to save the Spondylus System.

Cyborasaurus must be unleashed! The DYNOWARZ must begin!
