Which Assassin's Creed game introduced the multiplayer mode called Wolfpack?

Assassin's Creed III introduced the multiplayer mode called Wolfpack.

Wolfpack is a cooperative multiplayer mode in which players work together to assassinate computer-controlled targets. Teams progress through timed sequences, coordinating stealth, movement, and kills rather than competing directly in the traditional player-versus-player modes.

The mode appeared in Assassin's Creed III, released in 2012, alongside the game's competitive multiplayer options. It was later associated with Assassin's Creed IV: Black Flag, which expanded the series' multiplayer presentation but did not originate the Wolfpack mode.

The distinction matters because Brotherhood and Revelations introduced major competitive multiplayer features earlier, including modes built around hunting and evading other players. Wolfpack instead emphasizes cooperation against AI targets. Assassin's Creed III's multiplayer also included characters and locations drawn from the game's broader historical setting.
