The streaming service will be available for Xbox gamers in the US, UK and Australia Wednesday, with more regions coming soon. If a game supports streaming, it'll have a cloud icon on the Xbox digital store.
If a friend invites you to join a game you haven't downloaded, you'll also be able to jump in immediately via streaming.
This gives Xbox One owners the ability to play next-gen exclusives like Recompile, The Medium and The Riftbreaker on their older console, but you'll need a strong internet connection to get the best experience. More next-gen games, like, are coming in early 2022, the company noted.
