Update: I've been informed by a few industry sources that Golden Age was in fact the code name for Assassin's Creed IV: Black Flag.
Original post follows:
What comes after Assassin’s Creed Victory, which releases this year? According to an accidental leak by Ubisoft themselves, there’s an upcoming title called Assassin’s Creed Golden Age.
The leak happened to be in a recruitment brochure for the company, revealing an Assassin’s Creed game with the previously mentioned subtitle. Check it out below.
Keep in mind that the leak may not be ‘accidental’ and may in fact be a way of building hype for the upcoming game—but I don’t really care, either way, because it’s news of a new Assassin’s Creed.
At this point, it’s unknown whether Golden Age will be the successor to Victory, or whether it will be a spinoff/side-release like Rogue was to Unity.
The PDF file remains online, and can be downloaded from here, directly from Ubisoft’s website.
