there is something worth noting, which is, you can see that Chapter XIII has two Achievements, which are complete as Optimus and Complete as Megatron, does that mean that you can choose between playing as Optimus or Megatron in the final chapter, also, in ''Our World'' Trailer and ''Through The Matrix'' Trailer you can see Optimus using his sword against Megatron, so the final boss will be either Optimus or Megatron depending on who you chose and it will be an epic Sword-fight? i freakin love Sword-Fighting...also if the game could be completed with either Optimus or Megatron, does that mean there are two different endings?
