The 2015 edition of Assassin's Creed will be set in the city of London during the Victorian era, according to a Kotaku source, and will be called Assassin's Creed: Victory.
As announced by Ubisoft over the summer, development of Victory will be led by Ubisoft Quebec. It's expected that it will be the only "main" Assassin's Creed game released in 2015, and is currently planned to come out in the fall.
Kotaku described the seven-minute-long "target gameplay footage" video its staffers viewed as "slick" and said it could pass as an E3 presentation. The mission in the video once again pitted the Assassins against the Templars, and featured a grappling hook that allowed the assassin to go vertical.
