The game, which was announced and teased during the Xbox One reveal event, sets out to 'blur the lines between' TV and gaming, combining aspects of an adventure game with a TV drama series.
It's being developed by Remedy, who were responsible for the original Max Payne and Alan Wake. Judging from the footage shown, the Xbox One exclusive will feature long, detailed cutscenes a deep story and quality acting.
The visuals were on show were incredible, but whether or not the final product will look like the demo is something we'll find out later. You can see the footage below.
