They said that they are fusing single player with multilayer so by that I don't think they mean coop because they said it is the first cross player game. I think that it is like a normal single player game but all the NPC's that you fight are real people playing, same goes with people on your team.
What do you guys think of it?
PS: The guy who jumps down on that other guy sorta looks like a vampire
Edit: Sorry I didn't see the update on another board
