More information about Ubisoft's technically-unannounced Assassin's Creed 4 continues to leak today. Marketing materials revealed the pirate-themed "Black Flag," set to arrive some time before April 2014. A map from the game has been leaked by the same source to Kotaku, and it reveals some critical details about Ubisoft's next open-world game.
According to the map, the game will take place in 1715 across the Caribbean islands, a time that is referred to as the "Golden Age of Piracy." Although players did sail to the Caribbean in Assassin's Creed 3, those adventures didn't happen until the 1770s. The ship you commandeer in AC3--the Aquila--wasn't even built until 1749, meaning the upcoming AC4 predates Connor's journey by a number of decades.
A major raid on the Spanish by English pirates in 1715 could be one of the game's earlier moments, as it sets the stage for the events to follow. We wouldn't be surprised if Black Flag featured some of history's most famous pirates, namely Edward Teach--better known as Blackbeard.
