Cybertron is the home planet of all Transformers. Autobots and Decepticons once fought on the planet but now it is a deserted waste land. In the game Cybertron will once more become a battle zone for both Autobots and Decepticons.
In the Transformers Prime series Megatron planned to use Dark Energon to reawaken Cybertron's dead as his own minions and sent a large chunk of Dark Energon through a spacebridge from Earth to Cybertron. Upon impact, the Dark Energon awoke thousands of the deceased Cybertronians, which were commanded by Megatron to come through the Space bridge, leaving Cybertron more dead than before. Fortunately, the Autobots destroyed the space bridge, which in turn killed Megatron and the Terrorcons.
