The most recent Assassin’s Creed project, confirmed or announced by Ubisoft, is codenamed Assassin’s Creed Infinity.
Ubisoft is secretly developing a remake of the original Assassin’s Creed, using much of the work and assets created for Mirage.
Bloomberg in February reported that the game, then codenamed Rift, was originally planned as an expansion to Assassin’s Creed Valhalla, and stars a popular supporting character from that game, the assassin Basim.
