After retreating from the doomed Capital, the Republican and Imperial Forces have been going to Wendeen Lake. This is where the Republican's secret weapon, the Ultrasaurus was resting. A last-ditch strategy they will use to defeat the Death Stinger is under way. They are planning to awaken the Ultrasaurus, a heavy carrier zoid, which would provide them with cover and firepower to take on the Death Stinger. Colonel Herman believes there is only a 50% chance the Ultrasaurus will awaken. Van talks some sense into Colonel Herman and eventually makes him realize, he has to believe in the 50% chance the Ultrasaurus will awaken or it's hopeless. Six power blocks of the Ultrasaurus are ready for action and are functioning well to their maximum. Moonbay got an idea to kick start the seventh power block of the Ultrasaurus. Meanwhile, the Death Stinger slumbering in the molten lava within a mountain, it blows through the mountain with a Charged Particle Beam and sets out after the Ultrasaurus.
