I don't know if it's my computer or my copy of the game, but the audio is missing. When I'm suppose to hear one of the Autobots/Decepticons give me the objection of the mission. Instead of that, I only get to see their character icon without the dialog and just closes asap. Also, the animation sometimes look weird when fighting one of the drones or any other character.
So, I had to extract the game's DAT file and put it in a different folder along with the exe and the dll files. Now it works, yay!
