Assassin's Creed IV Black Flag: Illustrious Pirates Pack

This Pack/Addon for Assassin's Creed IV Black Flag, released in 2014, enhances the base game by adding three new explorable islands—Black, Mystery, and Sacrifice—where players hunt for treasure chests. The core loop involves exploration to unlock exclusive cosmetic items for Edward (outfits/weapons) and the Jackdaw (figureheads/sails). It also provides new, purely aesthetic customization options for the multiplayer mode, including costume sets, titles, and emblems. It requires the base game to access these supplementary features.
