Here's a list I'll update when we find out all of the playable characters, including Multiplayer ones. The list is for the main consoles only, not handhelds. Autobots: Optimus Bumblebee Ratchet Silverbolt Air Raid Jetfire Warpath Ironhide Sideswipe Arcee?* Jazz (Escalation) Decepticons: Megatron Starscream Soundwave Skywarp Thundercracker Breakdown Barricade Brawl Slipstream?* Shockwave (Escalation) Demolisher (Escalation) * - Announced unofficially EDIT: Added Thrust, still not sure whether he is an escalation exclusive or actually part of the campaign. I have bets on escalation. Why would there be four jets in the Decepticon campaign when there's only probably one or two levels with jets and the seekers take up the 3 places. post if there are other characters I've missed, and I'm not putting Grimlock yet, he hasn't been annonced and I'm not convinced. EDIT #2: Added Arcee and Slipstream, I'm not sure where they are playable but we know they are, and we don't know their official names.
