This is just the newest Battlefield edition. Is anyone else in the beta? It's pretty damn fun. If you're looking for a quick beta key, keep your eyes on their forums - for some reason they let people post beta keys for others to use. It seems like somebody posts 5 available keys a few times a day.
I've played but I find it incredibly cheesy. The game is comparable to TF2, which don't get me wrong is a fun game, but battlefield is not meant to be like this :P
Haha, yea it's very very cartoony. It kind of feels like one of those shooters where skill will never be a factor. Anyways, if anyone plays on the beta servers, I'm on the Nationals (the Nazi-looking dudes). My names are: Pro, Durnk, Scrub and Gunnerhea (haha)
