They already had the open beta, now it's closed, then it will be open again... It's actually a lot different than TF2... for one thing, it's third person... and EA pwns btw...
Pwns as in Hi I'm EA and we can't be original so we'll cell shade our old games from 5 years ago and slap a new name on it. Then we'll charge you a boat load of money for it because we know you're suckers like that. Yeah, I'll agree with that.
