On the first release there's no LAN game available, also no dedicated server.
Multiplayer is using Photon Cloud (
www.exitgames.com) so
everyone can start a multiplayer room (=server).
I'm not sure if LAN server is needed, cause we've played with 6 player over 1 internet cable without problems.
But it's planned for a future release to add LAN & dedicated server, cause if Photon Cloud (whyever) should stop supporting Unity 3D created games this would destroy the multiplayer part in EoD.
