Between the old-school Animus interface and the Ubisoft Digital Arts watermark, I'm positive this video is leaked footage of something Assassin's Creed related, but what?
I have no clue. It could be a cut scene from Assassin's Creed: Revelations, or perhaps a clip from the Assassin's Creed: Embers animated short that will come packed with the Revelations collector's and Animus editions. Whatever is going on here, it looks both sinister and painful.
While I thank reader Josh for passing the clip along (Thanks, Josh!), you folks can occupy yourselves theorizing over what it all means.
Update: As commenters have pointed out, the audio is taken from the 1990 film Jacob's Ladder. Check out the video below, starting at about the two minute mark. An animation test then?
Update 2: Sources tell us that this is an internal animation test, and it's a few years old. Still creepy.
