Another very fascinating thing here is how well the 360 is able to render the motion capture technology that is being used for this game. A good example is the end of the video where Cortana gives her "don't make a promise" speech. You can really see an actual actress within the model there. I mean it looks alive.
I don't know how they're pulling this shit off on hardware this ancient. It rivals anything out there.
To be fair; Ninja Theory did incredible work when it came to the mocap and modeling in Enslaved. And that was a couple years ago now. It was easily the best example of this gen till this latest crop of gen-ending titles were shown off: Halo 4, The Last of Us, Beyond.
Regardless, nothing sells a visual narrative more, and I'm glad to see gaming really get on the bandwagon.
