Fable 2 features cooperative multiplayer throughout the entire game, both locally and online over Xbox Live. Though the online component wasn't ready in time to ship in the retail version of the game, the developers have confirmed that a patch adding online multiplayer to the game will be available the same day the game comes out in retail stores.Lionhead: Official Fable 2 Development Blog (October 19, 2008)
Orbs
Online multiplayer in Fable 2 is controlled by in-game elements known as Albion Orbs. These orbs tell a player where anyone on the their friends list is in their own game at any given time. Through these orbs, players can chat and trade items with each other, or choose to play co-op in one of their games. This gameplay element was first demonstrated by the game's creator at E3 2008.Wikipedia: Fable 2 Co-op
