Transformers: Cybertron Adventures
Optimus decides to evacuate the planet。
Air Raid is sent into the planet's core to sabotage the Energon Bridge that feeds energy to Trypticon, which he does。
The Decepticons lead a new attack against Iacon as Bumblebee escorts supply convoys and Air Raid fights Decepticon Seekers led by Skywarp and Thundercracker。
Eventually Trypticon is repaired and begins destroying the escaping Autobot ships, and Jetfire is sent to attack relay stations that transfer energon into Trypticon。
Jetfire is successful, and Trypticon crashes down to Iacon。
Optimus leads a final assault against Trypticon, resulting in Trypticon's destruction。
With the spread of Dark Energon halted, the Autobots are able to remain on Cybertron。
The Decepticon campaign begins with Megatron scouring Ground Zero of Trypticon's blast and hunting down Autobot survivors。
He eventually chases down and defeats Ratchet。
Starscream is sent to protect the Energon relay stations from orbital debris- a task which Starscream despises。
While Megatron is busy in Iacon, Autobots infiltrate Kaon, and Soundwave and Barricade intercept the intruders。
Bumblebee and Ironhide are captured, and the Decepticons use neural scanners to interrogate Bumblebee for key strategical sites in Iacon。
