The demo is quite good. Except for one thing - the vehicles. They are, imo, pretty crappy. If it's not flipping for no reason, blowing up when relatively undamaged, or getting stuck on an enemy rifle, it's being unable to shoot along the horizon in a boat. I know vehicles aren't really the focus of the game, but when they are in the game, I expect them to work much better than the demo showcases. I hope that's something they tweaked for the final version.
