The first lobby-version is already released !
Port mapping isn't necessary anymore, although the communication in "direct-connect"-mode is more stable, if at least one player forwards ports 9999 & 10000.
Features of the Lobby-Version :
- Server sided save games
- Lobby Chat
- (Zoomed out) message history (L/R to go back/forth, SELECT to switch zoom mode)
- Invite players
- STILL MANY BUGS
