Just completed the game on medium and i have to say it was great.
Really enjoyed the whole game especially the flying missions they are all so EPIC. The levels are long but not long enough to be boring. I'm not sure if it's just me but the Deceptiocon campaign is a LOT easier. Probably because the Autobots have too much of these escort,save and protect missions. That's something i didn't really like. At the end of almost every "protect" mission the enemy has whole army and the only way you can survive is to crawl back into a hole somewhere. One other thing i didn't really like is that you can't play as the best characters(unlockables) in SP
But other than that it's a great game and i'm gonna play it for quite a while
