Dynowarz: Destruction of Spondylus is a game developed and published by Bandai for the Famicom and Nintendo Entertainment System. It was released in 1989 in Japan and in 1990 in North America.
From game box:
Something was terribly wrong in the distant man-made Spondylus Solar System. One by one the planet's central life support computers had been infected with a life threatening virus while the planet surfaces had been overrun with computerized dinosaurs known as Robosaurs. Under attack in his laboratory on Alpha Planet, Professor Proteus, the mastermind of the Spondylus System and the 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 has 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.
There are two modes of gameplay. The player controls either Professor Proteus in his battlesuit, or Cyborasaurus, a truly devastating Robosaur. Capsules that Robosaurs drop can help to keep these two entities alive. Capsules labeled "E" will fully replenish the player's energy. Capsules labeled "B" give the player a full barrier meter. Any damage taken will deplete the barrier meter before affecting the energy meter.
Stages, each on different planets ranging from ice to jungle, begin by piloting Cyborasaurus. The goal is to get to the Artificial Intelligence Compound of each planet. Hoards of Robosaurs stand in the way of Cyborasaurus, including a boss of each level. These behemoths can take far more damage than standard Robosaurs. When defeated, the boss will leave behind a key to the AIC.
When in the AIC, Proteus exits Cyborasaurus. Every AIC has a Life-Support Computer that has been infected with a virus which must be destroyed. Platforms of Deception, Flying Hounds of Destruction, and other obstacles must be circumnavigated before battle with the hideous pulsating Life-Support Computer can begin. When the computer is destroyed, all beasts in the AIC are destroyed along with it. Proteus must then retrace his steps back to Cyborasaurus. Cyborasaurus then must use the Molecular Transporter outside to travel to the next planet.
