As seen in the image, it has some Native American influences, including a bow and arrow, an axe, headdress and a necklace. The character is also wearing cowskin boots and also an American Revolutionary pistol.
This seems to confirm the popular rumors of Assassin's Creed III taking place during the American Revolution. Nothing is certain right now, but Ubisoft will be making a major announcement about it next week. Now that the storyline of Ezio and Altair have come to an end with Revelations, let's see what this one will bring.
God Bless and Play Hard Gamers!
