I didn't realise this game might have an FPS angle, I would have just called it an action game but after seeing the video (checkout the HD version at linky below) of multiplayer in action It sort of "felt" like a take on an FPS title multiplayer being added to the game.
Transformers 2, which they confirmed at the end as hitting shelves for June 23rd, has an Autobots vs Decepticons multiplayer game. The DCs can fly around and tend to be larger while the AB's are smaller and harder to hit, faster on the ground. I have to say that this sounds very unbalanced. If complete nubs are playing the decepticons then sure the autobots will play well, but if the decepticons have people that can aim well they're bigger, tougher, and can fly... I'm hearing balance alarm bells going off like crazy. I like what they're doing with this but I don't think the game is translating from movies to multiplayer in a very friendly manner.
