Ubisoft has released the Assassin's Creed 4: Black Flag gameplay demo from E3 2013. If you tuned in to Sony's PlayStation press conference then there's a good chance you've already seen this when it was played on stage using the PS4. Unfortunately, the demo suffered from constant stuttering until the entire finale just cut out and froze. Ah, the joys of live demos at press conferences.
Anyways, if you want to watch the entire AC4: Black Flag E3 demo played in smooth motion, without interruption, and with commentary from game director Ashraf Ismail, then you can now do so. Throughout the demo he will point out new features and gameplay mechanics present in Assassin's Creed 4: Black Flag, as well as detail made possible only with the PS4 and Xbox One.
