The next Public Build will be available soon (uhm, few weeks...)
The Updater will be enabled, and you'll find a lot of new stuff. I think. I guess. Yeah.
The Lobby will be the main Frame, so when the user will open the Game, he will join it automatically. If he has a profile, that is. New weapons will be available, a few maps too, and new features. I haven't really started the Story mode though... I guess that'll have to wait for another few months
I'll post screenshots soon.
