Part of the fun of the Assassin’s Creed series is guessing where and when the next title may be set. If recent rumors are anything to go by the next installment could take players to ancient Greece in 2019.

In a report on Comicbook, Liam Robertson has said that several sources close to Ubisoft have told him the next Assassin’s Creed game is to follow the Egyptian setting of Origins with Greece and is scheduled for a fall 2019 release. The game apparently entered full production in early 2017, well before the release of Origins.
