My friend, who is one of the top 10 Revenge of the Fallen players in the world (I know, exciting huh?), has been following this game for a long while. Revenge of the Fallen's community has moved over, which is fair sized since the old Chrome Hounds community fused with it when their servers went down.
From what little I've seen of the Demo it looks like an alright game. The odd 3ed person angle they have takes some getting used to, but overall its a typical class based 3ed person shooter.
