Please note that this indicator does not imply the ability to play games over the cloud with Xbox Game Pass, but rather access to them. even if you are not subscribed Via a browser using the Xbox Cloud Gaming services, as is already possible with Fortnite. The difference is that Epic Games is free to play, while in Red Dead Online and GTA Online you have to own the game.
This integration is perfect for those who want to be able to play anywhere and from any browser (subject to a fast enough connection, of course) or for those who just don’t have enough modern hardware to run such games.
This is what we know for now. We have to wait for more precise information from Rockstar or Microsoft.
