Ubisoft hasn't finished supporting the previous installment of the franchise.
This summer, Ubisoft teased a free update with new content and improvements for Assassin's Creed Mirage. Recently, players remembered it again.
An announcement appeared in the menu: the presentation is scheduled for October 6, 7:00 PM Moscow time.
Judging by the dataminers' findings, this update / add-on for Assassin's Creed Mirage will be called "Valley of Memory."
