This is downloadable content (DLC) for Assassin's Creed IV Black Flag, released in 2013, requiring the base game to play. It offers approximately 60 minutes of exclusive adventure and platforming gameplay centered on the character Aveline. The story focuses on Aveline's commitment to liberating slaves during a period of personal uncertainty. It integrates directly into the main game's structure, providing a brief, focused narrative side-story rather than introducing new core mechanics.
