Great fun. Lag is annoying as hell, though. That comes with a beta that everyone and their grandma is accessing and playing. Only major gripe right now is lack of a prone option. You can crouch, just not go prone. However, mowing down trees so you can get a better view of a far-off area so that you can shoot down a helicopter with a mounted gun emplacement is just... wheee!
+30 vehicle damage
+100 vehicle destroy
+50 enemy kill
Score.
