The civil war has gone badly for both sides of the conflict on Cybertron. Their planetary core has shut down, and with it, the life giving energon it produced. Soon their world will be a barren husk, devoid of any ability to sustain life, fit only for those creatures that scavenge from the dead, and perhaps soon, not even them. Having evacuated as many of the Autobots and non aligned as he could, Optimus Prime turns his attention to the final transport, The Ark, which will take the bulk of the Autobot army to the stars in search of a new home. The Slagmaker himself, Megatron, leader of the Decepticons, however, has no intention of letting them escape his wrath, though he too knows that Cybertron's days are numbered.
