Update: The trailer for Assassin's Creed IV: Black Flag is now officially available. Check it out here.
---------------------
The premiere trailer for Assassin's Creed IV: Black Flag appeared briefly on YouTube revealing a few unknown details about the game, like its release date.
The trailer was quickly pulled, but before it went down we learned the game will be releasing on October 29 on all current generation consoles, as well as next-gen consoles, plural.
The trailer showed the pirate Blackbeard weaving a tale of a new pirate captain describing his combat prowess as, "fighting like a devil dressed like a man." That devil man, was of course Black Flag's protagonist. The full trailer should be availble in non-leaked form very soon.
As mentioned, the trailer has already been pulled.
