Questions about multiplayer

[AdamN]

Well, if all players can connect to adhoc server but can't see each other, the issue is mostlikely to be existed on players side (usually ports need to be opened on each player)

Adhoc server only create a friendlist (players within the same group), and game communications are done peer2peer (directly player to player) without going through adhoc server, so each player need to have opened ports also (varies ports depend on the game)
