They opened up Caspian Border again for the PC beta. While now you don't get as much of a cluster of players in an area like with Metro, the added vehicles and aircraft make for some fun moments.
Like controlling an AA turret while having an enemy jet flying straight at you and you have to try and shoot him down. I also had an enemy jet clip a building next to me and crash right next to me.
Lastly, I was in an AA turret and looking around. I saw allies get in our chopper and I looked away. As I was panning my view, the chopper flies into the building right in front of me and explodes.
