Didn't see any threads like this, so I figured I would start one. there are 2 secret acheivements, anyone know what they are? Maybe if you get them it unlocks 2 extra characters like in the first game with Arcee and Slipstream. Also, what do you think the achievement "the Last Stand" is about? "Chapter II: Save two Autobots when Optimus is downed by the first Leaper" Maybe you play as Jetfire in Chapter 2?
