The only thing the gametype does towards the UI when you join a server, is to grey out the choose teams so you can only pick autoassign, for which it autoassigns you to the obvious survivors team, but as soon as you press auto assign, you will still have to click a class loadout for it to actually take your guns away from you and give you the infected loadout, I tested this on an openwarfare SVN copy, just now, and it doesn't bypass the chooseclass menu when you join, only greys autoassign out, what i'm trying to do is make it so spawning in is automatic for newly connected players.
