I have been playing the multiplayer open beta since it was released.
If you have an XBOX and want to play along side me, then message me with your gamertag.
I will say this... even the beta is MUCH more fun than Bad Company 2 ever was. They have really outdone themselves with this game! ^_^
Edit: Also if you're worried about all the glitches in the beta.. don't worry about that.. people have been sending in reports about the glitches and they will be fixed for the final game indefinitely.
Edit2: Oh, and if you're wondering why your profile hasn't been saving... You have to log on to
battlelog.battlefield.com and activate your account on that so it can carry over to the full game I believe.
