"Since the beginning, [we've noted] online can potentially be an issue," Joye said. "We'll see what we do with it. Xbox One also is something that [Microsoft] is working on, their whole Live system behind it. We're not aware of everything Microsoft is doing on their side, so we can't detail anything right now but we'll see later."
After I briefly tried the offline multiplayer at a Gamescom demonstration, International Product Manager Aymeric Evennou said Ubisoft will detail the game's other modes in the months before it hits shelves on Xbox One launch day.
The website for the Xbox One game states friends can "compete online against the world to become the ultimate fighter," but Joye's comments suggest nothing is clear cut.
