You might have seen a developer driven demo of Assassin's Creed IV: Black Flag during Sony's press conference. The video below is different in two significant ways.

First, it includes commentary from game director Ashraf Ismail. Second, it doesn't stutter and crash right before the end.

Take a look at how the team at Ubisoft Montréal is using next-generation power to enhance the series' stealth aspects. Additionally, the transitions from land to sea open up mission design possibilities.

Assassin's Creed IV: Black Flag arrives on PC, Xbox 360, PlayStation 3, and Wii U on October 29. PlayStation 4 and Xbox One versions are also in the works.
