Which Assassin's Creed game introduced the setting of Victorian London?

Assassin's Creed Syndicate introduced the setting of Victorian London to the main Assassin's Creed series.

Released in 2015, Syndicate follows twins Jacob and Evie Frye as they fight Templar control over London during the Industrial Revolution. The playable city includes districts such as Westminster, the City of London, Southwark, and Lambeth.

The game emphasizes industrial-era technology and transportation, including trains, carriages, and a grappling launcher. It also features historical figures such as Charles Dickens, Charles Darwin, and Queen Victoria.

Syndicate is sometimes confused with Unity because both games focus on European cities and feature dense urban parkour. Unity is set in Paris during the French Revolution, whereas Syndicate moves the series to 19th-century England.
