[quote name='tiredfornow']Do you get to play as Sam in the Transformers game, LinkinPrime? And is it open world?[/QUOTE]
No...you select your faction at the beginning, Autobot or Decepticon...then each mission has you play as a different robot.
You're talking about the first game right? I have yet to play the 2nd one...it's on my queue for later.
