Ubisoft have unveiled the first Gameplay footage for Assassins Creed IV: Black Flag today. The trailer features two minutes of gameplay showing off the game world and further introducing Edward Kenway.
Seeing as Kenway is a pirate, it is no surprise then that the trailer features the sea quite heavily. Along with several beautiful shots of your ship at sea, the updated naval battles are on show here. Its not all life on the high seas though, as it shows off some of the underwater exploration and deep sea diving (including shark punching!).
