Btw, the multiplayer is awesome but a little hard to host/set up.
I laughed my ass off last night when I played coop with some friends and we tried to fly the chopper. I was flying it and accidentally jumped out the window (damn Y button)! While I fell laughing, the rest of my team were scrambling to see if one of them could fly...they couldn't and the chopper crashed!!! I had tears in my eyes I was laughing so hard.
