IGN reckon it's the best multiplayer experience going on PS3 (or console period?), but the campaign is a bit wank story-wise.
I played the beta quite a bit, and unless they have put something in place to stop cunts selling your buildings to place their own (or each person has a private building allocation which would be my preference) they can stick it.
Plus, the 'hawks now don't fly as nicely as in Warhawk IMO. The walkers are weak as shit (2 rockets - really?).
But to be fair, a lot could have changed since I played it. It was fun for a while...
