It might seem like Ubisoft has already revealed every detail there is to know about Assassin's Creed 4: Black Flag. The pirate simulation game's sea battles, Caribbean exploration, assassin gameplay, and "fort assualts" have all been detailed in the past few months.

Gamers will be able to access taverns after a ritual fistfight, climb (and jump off of) viewpoints, and harpoon sea life. Other activities include diving into underwater shipwrecks to gather loot and storming into smuggler hideouts to do the same.
