Assassin's Creed IV: Black Flag

Assassin's Creed IV: Black Flag is a 2013 historical fiction action-adventure open world stealth video game developed by Ubisoft Montreal and published by Ubisoft. It is the sixth major installment in the Assassin's Creed series. Its historical timeframe precedes that of Assassin's Creed III (2012), though its modern-day sequences succeed III‍‍ '​‍s own. Black Flag was first released on the PlayStation 3, Xbox 360, and Nintendo Wii U in October 2013 and was ported to PlayStation 4, Microsoft Windows, and Xbox One the next month.

The story is set in the early 18th century Caribbean during the Golden Age of Piracy, and follows notorious pirate Edward Kenway, grandfather of Assassin's Creed III protagonist Ratonhnhaké:ton and father of Haytham Kenway, who stumbles upon the conflict waged by the Assassins and Templars. Unlike previous games, gameplay elements focus more on ship-based exploration in the open world map, while also retaining the series' third-person land-based exploration, melee combat, and stealth system. Multiplayer also returns, albeit with only land-based modes and settings.

The game spans across the Caribbean ,with the three main cities of Havana, Nassau and Kingston, along with numerous islands,sunken ships and forts. Players have the option to harpoon large sea animals, in addition to hunting land animals. For the first time in the series, naval exploration became a major part of an Assassin's Creed game, where Edward Kenway captains the Jackdaw, a Brig he captures from a Spanish fleet.
