Ubisoft's France-based studio Ubisoft Annecy is developing Assassin's Creed III's multiplayer, continuing the duties they performed for Brotherhood and Revelations.
The folks at GamerZines spotted that the Twitter Profile of Tim Browne - who recently joined the Ubisoft Annecy team - notes that he's the "Lead Game Designer on Assassin's Creed 3 Multiplayer @Ubisoft - Annecy" - which is pretty conclusive.
Fans will be pleased to know that the multiplayer is in the same safe hands that handled the mode for the previous two Assassin's Creed titles. The studio also handled the multiplayer for Splinter Cell: Chaos Theory, so have something of a history of doing the multiplayer adaptations of Ubisoft franchises.
Thus far Ubisoft has only officially named Ubisoft Montreal, the core Assassin's Creed studio, as working on the title.
Xbox.com recently listed the title as having four player co-operative play. Previous titles only featured competitive multiplayer.
