As previously teased, Ubisoft just officially announced Assassin's Creed: Syndicate, which will tell the tale of Jacob and Evie Fye in a dark and gritty Victorian London.

The game will launch on October 23rd on PS4, Xbox One. The PC version will release at a later time (Fall 2015). Interestingly, there will not be any multiplayer mode, and the title will be purely single player.

It will be possible to drive vehicles (we saw horse carriages so far), and the games integrates them with parkour and combat. There will be a full fledged traffic system in Assassin's Creed: Syndicate's London.

New weapons and tools will include a revolver and a rope launcher.

Below you can read the official blurb and bullet point.

London, 1868. The Industrial Revolution unleashes an incredible age of invention, transforming the lives of millions with technologies once thought impossible. Opportunities created during this period have people rushing to London to engage in this new world, a world no longer controlled by kings, emperors, politicians, or religion, but by a new common denominator: money.

Not everyone is able to enjoy the benefits of this boom, however. Despite fueling the engine of the British Empire, workers’ lives are little more than legalized slavery while the top few percent profit from their labor. Living poor and dying young, the lower class unite in protest as a new kind of family, gangs, who turn to a life in the underworld in their struggle to survive. A struggle, until watchful Assassins come to their side and re-ignite an age-old conflict involving London’s leaders that will echo throughout modern history, from the underground up.

Introducing Jacob Frye, who with the help of his twin sister Evie, will change the fate of millions in Assassin’s Creed® Syndicate. Rise to rally and lead the underworld to break the corrupt stranglehold on London in a visceral adventure filled with action, intrigue, and brutal combat.
