The Director of development of Assassin's Creed II: Black Flag Ashraf Ismail explained to OPM that besides strengthening the element of naval battles and introduce new features like searching for treasures in the game was greatly improved the stealth aspect, so that those who want to play the story entirely with a stealth approach.

This is done by making more simple and effective rules that govern the way we discovered by enemies, how to escape back to hide and obviously the stealth infiltration component. While you play will now be easier to understand when you are likely to be discovered, so that the player can focus solely on its target; also new tools as a Blowpipe will bump off enemies from afar and silent manner.

We have to wait for the release of the game, waiting for the 21 November, to find out if fans of stealth will be really satisfied.
