French publisher Ubisoft on Thursday confirmed development Assassin's Creed Revelations, a Ubisoft Montreal game that the company says is the "final chapter" in the Ezio trilogy. The game is slated to launch on Xbox 360, PlayStation 3 and PC this November. It will be the latest installment of one of Ubisoft's tentpole franchises, which debuted in 2007 and has since sold 28 million units. While Ubisoft Montreal is leading development of the game, other Ubisoft subsidiaries are also contributing to its development, including Annecy, Massive Entertainment, Quebec, Singapore and Bucharest. The publisher called Revelations the culmination of the the trilogy that stars Ezio Auditore. Along with a new storyline set in Constantinople and fresh gameplay updates, Ubisoft said it would also expand online multiplayer features. Ubisoft Montreal creative director Alexandre Amancio said the company will show more of the game at this year's E3 conference in June.
