We already got an early look at Assassin's Creed III last week with a small batch of screenshots. Granted, they didn't do much to show us exactly how graphically different it would be from previous titles, but we were given a glimpse of the new Assassin and some new environments.
Ubisoft follows up today with the announcement trailer, featuring more of the Assassin Ratohnhaké:ton, better known to his peers as "Connor." The guy is both Native American and English, which doesn't exactly make life easier in 18th century America. Still, the man finds a way, and eventually becomes a symbol of justice and freedom in ongoing war between Templars and Assassins.
There has been no mention of any special editions yet, but Ubi did throw out a pre-order bonus. Pre-ordering from any major retailer will automatically snag you the special SteelBook case designed by the famed Alex Ross, which you can see in the gallery below the trailer.
