Your eyes do not deceive you, that is indeed G1 Starscream!  He will be included in the first batch of DLC for Transformers: Revenge of the Fallen.  The DLC is also going to include a new Expert difficulty level, three new multiplayer maps, nine other new bots (including Movie Sideswipe) for multiplayer and single player action, and of course, new achievements and trophies to unlock.

As soon as we get more information on what other bots are coming in this pack, when this DLC is coming out, and how much it will cost, we will update you.
