A peculiar note appeared on the net today regarding how there will be no LAN or Dedicated Servers support for C&C4. The lead designer explains thusly:
"...across single-player, multiplayer and skirmish and all the information is stored in a server. So if you go to another machine -- friend’s house, Internet cafĂ© -- whatever, you can login with your profile and all the stuff you’ve unlocked is accessible to you there. It all lives on a server so you can’t really do dedicated servers with that."
