Assassin's Creed IV: Black Flag is a 2013 action-adventure 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), but its modern-day sequences succeed III's own. 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. It was later ported to the Nintendo Switch as part of The Rebel Collection alongside Assassin's Creed Rogue in December 2019. The game was released for Google Stadia in September 2021.
