Ubisoft is keen on showing off one of the key features of Assassin's Creed IV: Black Flag. Naval gameplay was introduced in III, but it's being expanded for the pirate-themed entry it's more suited to, and you can see how it looks in the world premiere clip below.
Assassin's Creed IV also has a limited edition on the way for Xbox One, PlayStation 4, Xbox 360, PlayStation 3, and PC. Unfortunately, it appears Wii U owners are out of luck. The limited $129.99 release, pictured below, comes with an 18" Edward Kenway statue, a 28" x 48" pirate flag, an 80-page art book, a steelbook game case, and the complete soundtrack.
Assassin's Creed IV strikes current consoles and PC first in North America on October 29.
