Best $15 dollars I've spent in a while.
Classic battlefield conquest play. Three classes that are for the most part well balanced. Good vehicles, good maps. Though there are only three maps (with a 4th-plane only map on the way), they are big enough to have a unique experience based on how you want to play it. Lag is almost not an issue, but I have noticed twice...out of 40 games. The only thing I don't like is there is no weapon upgrades for ranking up. Which has always been in a BF game. On the pluss side of that, no one has a clear advantage over you. I still think it would have been nice.
So, while there is a bit of a lul in good shooters out right now get this game. Well worth it, and it should keep you satisfied for a couple months. There are a ton of people playing it already.
