In Assassin's Creed IV: Black Flag, which region serves as the game's main setting?

Assassin's Creed IV: Black Flag is mainly set in the Caribbean.

The 2013 game follows Edward Kenway, a Welsh pirate and privateer who becomes involved with the Assassin-Templar conflict. Its open world includes islands and coastal cities such as Havana, Nassau, and Kingston, all presented within the Caribbean setting of the early 18th century.

Naval exploration is central to Black Flag. Edward commands the Jackdaw, upgrades the ship, hunts valuable cargo, and engages enemy vessels in broadside combat. Players can also explore islands, settlements, plantations, and underwater wrecks.

The game is often remembered primarily as a pirate adventure, but its story remains connected to the wider Assassin's Creed mythology. Black Flag also includes a modern-day Abstergo Entertainment storyline, in which an unnamed player character examines Edward's memories through the Animus.
