Which Assassin's Creed game is set during the London Industrial Revolution?

Assassin's Creed Syndicate is set during the London Industrial Revolution.

The game takes place in London in 1868, near the height of the Victorian era. Twin Assassins Jacob and Evie Frye leave Crawley for the capital and work to weaken Templar control over the city's criminal, political, and industrial institutions. Its story features factories, railways, gangs, and prominent historical figures.

Syndicate was released in 2015 for PlayStation 4 and Xbox One, with a Windows release later that year. Its setting is often confused with Unity's Paris or the colonial locations of Assassin's Creed III. Syndicate also introduced a grappling-hook launcher to help the Frye twins cross London's rooftops and streets.
