• There will be an Autobot Game and a Decepticon Game for Nintendo DS, supporting 4 way multi-play.
• The PSP will a version of the game (maybe different from all), but with 4 way Multi-Play.
• Wii will get special Wiimote functions, such as throwing things, steering, etc.
• You can play as 9 Autobots and Decepticons. Unplayable characters are going to be boss characters or other important characters.
• There will be unlockable characters and possibly movie characters that don't appear in the movie (like Wreckage).
• There will be G1 references in the game.
• It has a full interactive environment where you can pick things up and throw it at the enemy...including a Burger King sign.
• Burger King and Pepsi references were in the game, so we know they are sponsors.
• As the robot you can punch, shoot, jump, transform at will and drive/fly around when you are in vehicle mode.
• Autotargeting will be available.
• For game play, it reminded me of Grand Theft Auto, where you can run around the city (perspective was similar to GTA). The steering of the vehicle looked well done, where you could oversteer around turns, etc. If you caused too much ruckus the police would come and the pedestrians would go around screaming, especially if you were in Robot Mode (so being in disguise is important). Pedestrian interaction was not completed yet, but we were hoping you could pick up people and thrown them.
  
• Storyline is different based upon if you are an Autobot or a Decepticon, humans are part of the story, but not part of the gameplay. Because of the dual roles the Decepticons can win in this one.
