Assassin's Creed: Codename HexeUbisoft Montreal
Official details are thin on Hexe, but it appears to have a horror slant, and Cote said it would provide “a different experience” in terms of game and game structure. It is heavily rumored to be set somewhere in the Holy Roman Empire during the infamous Witch Trials that were prominent in the 17th century. "Hexe" is German for "Witch" and in itself hints towards this setting.
Project Hexe is being led by Clint Hocking, who previously worked on Far Cry 2 and Watch Dogs: Legion. It will launch into the Assassin's Creed: Infinity Hub.
