This game was fun to play, but also a little bit boring.
I think this was made more for the hardcore Transformers fans, since I didn't really enjoy wandering around a city where everything was made of metal everywhere, no matter where I looked there was metal and mechanics (but what would you expect from Cybertron). There is not much else they could have done, but I simply like the Transformers better if they are on the Earth a lot more.
It was cool to play Co-op, but you cannot communicate at all, neither kick. Often people joined and couldn't play at all, they kept dying which meant we had to start over again from the last checkpoint. And some of them just didn't want to learn how to avoid attacks from a boss so I ended up playing it entirely singleplayer sometimes.
It doesn't feel that natural to drive around in their vehicle form, but on the other side it was a little bit fun.
You have a lot of action in this game and an interesting story. I liked the Autobots story a lot more.
After completing the Autobots story it made me feel proud of myself.
All in all I would have to recommend this game, but only if you are familiar with Transformers and a little bit interested.
