We're not sure exactly what this is, but it we like it. It looks like a highlight reel designed to show off the skills of the ENSO team of stunt designers and performers, but it includes lots of shots of scenes involving Deus Ex: Human Revolution characters. There's a convincing likeness of Jensen at 1:55 and Human Revolution boss Yelena Fedorova appears at 00:23. It's not hard to imagine the big guy in the car park as Barrett.
There's evidently a bit of a budget behind it. It may well be part of an official ad campaign or upcoming short film licensed by Square Enix. It could even be a fan project. Either way, we want to see more.
