Black Flag was originally released for PlayStation 3, Xbox 360, and Wii U in October 2013 and a month later for PlayStation 4, Windows, and Xbox One.
Its historical timeframe precedes that of Assassin's Creed III (2012), but its modern-day sequences succeed III 's own.
It is the sixth major installment in the Assassin's Creed series. Assassin's Creed IV: Black Flag is a 2013 action-adventure video game developed by Ubisoft Montreal and published by Ubisoft.
