is using the UE3 and they have released a new trailer today. this is looking to have the potential to be a "rare" good TF game. although the two released trailers are movies not gameplay it still looks alot better then both the bay films. if you are wondering this will be a 3rd person sooter with a camera similar to GoW. here is a link to the latest trailer. dam i love the UE3 ^^ also in this trailer you can clearly see BOTH Tripticon AND Omega Supreme!
