Used to play this last year or before, we played up a lot on air but all the tiering has changed!
Now there are tanks too, it's not very complex and last time I played you couldn't play tanks/air arcade only one or the other.
Back when I played it was basically a 6 bomber rush to enemy airfield for the instagib, not sure what the meta is now, but it's a pretty fun game if you have a nearby server. It is horrible with lag because your controls are validated on the server - if you turn your plane then you have to wait for the ping to go there and back again before it moves!! VERY HARD GAME TO PLAY WITH EVEN SLIGHT PING!
