Below we've got a video of the Machinima app, an Xbox One exclusive set to be available for launch.
With its 'Wingman' content, the app lets you watch walkthroughs as you play, sitting snapped to the side of the screen. Alternatively, you can expand it to fill the screen and your game will pause.
The video below shows the app being used with Dead Rising 3. Machinima says the app will launch with a number of videos related to some of the console's launch games.
