i had this idea for a sequel for Hearts of Steel. Autobots and Decepticons fight each other once again but the Quintessons arrive to earth and invade London. Now the Autobots along with Tobias Muldoon, Nikolai Tesla and H.G. Wells must find a way to stop the Quintessons and save London. i read Infestation 2 and i noticed some plot holes like How did Optimus Prime end up at the Mare Rurek Glacier? also i was thinking ideas including the Quintessons use tripods and Megatron taking the form of a Tripod.
