Storyline

On the planet of Cybertron, the Transformer war between the heroic Autobots and the evil Decepticons rages on. But the losses are mounting up, and the war's front has been pushed into the heart of Autobot territory. The Autobots’ last stand takes a turn for the worse when the Decepticons introduce their secret weapon: the new Decepticlone army. As if by fate, a distress signal from the Mini-Cons, the long-lost third Transformer race, blasts onto the battlefield. Knowing that the Mini-Cons will tip the balance of power, the Autobots and the Decepticons race to Earth. On Earth, the Decepticons and their army invade the planet with extreme prejudice. It is then up to the Autobots to save Earth and prevent the Decepticons from controlling the universe.
