Peter Molyneaux showed off the long awaited (but pretty much expected) online co-op mode for Fable 2; but he had one surprise up his sleeve. The surprise was a seemless co-op experience which integrates into your single player game. At anytime while walking around the game world you will see these orbs floating around, they represent your friends currently playing the game and their spot in their respective worlds. Simply walk up to the orb, and you can invite your friend into your world.
Peter also announced the game is finished and is shipping this October. We've posted a handful of new screenshots after the jump.
