Assassin's Creed IV: Black Flag is a historical action-adventure open world video game being developed by Ubisoft Montreal and published by Ubisoft. It is the sixth major installment in the Assassin's Creed series, a sequel to 2012's Assassin's Creed III modern story and a prequel to its historical storyline.
The game features three main cities; Havana, Kingston, and Nassau, which reside under Spanish, British and pirate influence, respectively. The game also features 50 other 'unique' locations to explore, with a 60/40 balance between land and naval exploration.Assassin's Creed IV has a more open world feel, with missions similar to those found in Assassin's Creed, as well as fewer restrictions for the player. The world opens up sooner in the game, as opposed to Assassin's Creed III, which had very scripted missions and did not give players freedom to explore until the game was well into its first act. The player will encounter jungles, forts, ruins and small villages and the world is being built to allow players much more freedom, such as allowing players to engage, board, and capture passing ships and swimming to nearby beaches in a seamless fashion. In addition, the hunting system has been retained from Assassin's Creed III, allowing the player to hunt on land, and harpoon in the water.
