Transformers: Cybertron Adventures
Both campaigns open with Trypticon attacking the Autobot Capital City of Iacon。
The Autobot Campaign begins with Sideswipe scouring the blast site for Autobot survivors, rescuing an injured Ratchet in the process。
Bumblebee and Ironhide are sent to the Decepticon city of Kaon to retrieve intel on Trypticon。
Both are captured and imprisoned, but they escape the Decepticon prison with assistance from Air Raid。
Ironhide reports that Trypticon is spreading Dark Energon- a substance poisonous to Autobots but not Decepticons- through Cybertron's core, and that the planet will soon be uninhabitable for the Autobots。
