Which Assassin's Creed game introduced the multiplayer mode that let players hunt one another as Templars?

Assassin's Creed Brotherhood introduced the multiplayer mode that let players hunt one another as Templars.

Released in 2010, Brotherhood included a competitive multiplayer component in addition to its single-player story. Players controlled Templar agents, selected from distinct character archetypes, and hunted assigned targets while trying to remain hidden from their own pursuers. The system rewarded stealth, disguise, timing, and careful movement through crowded environments.

The multiplayer mode used maps inspired by Renaissance locations and included modes such as Wanted and Manhunt. It was separate from the campaign's narrative about Ezio Auditore rebuilding the Assassin Brotherhood in Rome and fighting Cesare Borgia.

Later games expanded or revised the multiplayer concept, but Brotherhood was the series entry that first introduced it. Assassin's Creed Revelations continued competitive multiplayer, while Assassin's Creed III also included it. Unity instead emphasized cooperative missions within its campaign world.
