However, it's not always about how much hull plating or fire power you've got. Some story missions force you to upgrade the ship, while others become much easier with a better outfitted Jackdaw. In Assassin's Creed 4: Black Flag, upgrading the Jackdaw is one of the most important parts of the game.It DOES NOT change facials or hair, do not panic XD that is a different mod. This mod replaces the Politican's outfit (you can buy that one for 12000 since the start) with the original Duncan Valpole one, or with versions of an actual British Royal Navy officer (lieutenant to be more precise) outfit.Black Flag has better shanties, banter, and a tropical setting that emphasizes the loose, spirited feeling of the Caribbiean golden age of pirates. Rogue simply employs the same mechanics as means to upgrade your ship. Black Flag emphasizes the fun, danger and freedom of actually being a pirate.
