The next Assassin's Creed game will be, Assassin's Creed Victory, set in 19th century London. The leak came by way of a Kotaku source, according to them the game will be released on PS4, Xbox One and PC. The source has also said that Victory will be the only Assassin's Creed game out next year, not following the format of two games like this year, Assassin's Creed Unity ans Assassin's Creed Rogue.
The development is being led by Ubisoft's office in Quebec, not Ubisoft Montreal who have been responsible for developing most of the major games in the series since 2007.
Kotaku have also reported that they saw a seven minute gameplay video which showed off its city traversal, combat and a new grapple hook.
Ubisoft have provided a statement that seems to confirm this leak.
It is always unfortunate when internal assets, not intended for public consumption, are leaked. And, while we certainly welcome anticipation for all of our upcoming titles, we're disappointed for our fans, and our development team, that this conceptual asset is now public," a representative said. "The team in our Quebec studio has been hard at work on the particular game in question for the past few years, and we're excited to officially unveil what the studio has been working on at a later date. In the meantime, our number one priority is enhancing the experience of Assassin's Creed Unity for players.
With Assassin's Creed Unity launching with a myriad of problems, perhaps people will be cautious of this game or maybe the schedule that Ubisoft has for the Assassin's Creed series will have to be looked at. Either way Assassin's Creed Victory is reported to be out fall 2015.
