Where do apps live?​

Apps can run in several different environments, which you can always mix and match to create the perfect experience:

  • In-Game Overlays

    In-Game Overlays

    Using overlays, apps can extend a game's UI, create value in otherwise 'dead' moments, or just generally work as seamless extensions of the game. Minesweeper during loading screens anyone?

  • Independent Desktop Windows

    Independent Desktop Windows

    Apps can also provide native desktop windows, containing anything from game debriefing, performance analysis, highlights management, and much much more, running regardless of a game.

  • Second Screen Views

    Second Screen Views

    As more and more gamers adopt setups with more than one screen, so can your app expand. Provide even better, more detailed functionality during the game, without hiding even a single extra in-game pixel.
