Kotaku got their hands on a video for the next Assassin's Creed game called Victory, featuring Assassin's against Templars in Victorian London. Ubisoft has responded to the leak confirming the game's legitimacy:
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. 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.
