Ubisoft will officially announce the next Assassin's Creed on Tuesday, May 12, the publisher said today.
If you read Kotaku, you already know a lot about it: this year's AC game is set in Victorian London and, if early footage is anything to go by, will let you use a grappling hook and fight on carriages, among other new features.
Incidentally, I'd heard from a source a couple weeks ago that Ubisoft planned to announce the game during a pre-recorded stream on May 12, but hadn't corroborated it. I also heard from the same source that the game is no longer called Victory and in fact will be called Assassin's Creed Syndicate. We'll find out for sure next week.
