Microsoft's xCloud streaming service will be part of the company's Game Pass Ultimate subscription.

In a post on Xbox Wire, games boss Phil Spencer (pictured) wrote that the cloud platform will be included in Game Pass Ultimate starting in September. This is when the xCloud is being rolled out "in supported countries." There's no word yet on which regions the streaming service will be launched in just yet, but it's safe to assume that it will be released in the countries where it has launched in beta. 

"Cloud gaming in Xbox Game Pass Ultimate means your games are no longer locked to the living room," Spencer wrote.

"You can connect more than ever with friends and family through gaming. And just like you do with your movie and music streaming services, when cloud gaming launches into Xbox Game Pass Ultimate, you can continue your game wherever you left off on any of your devices."

xCloud was announced back in October 2018 before a US beta for the tech rolled out 12 months later with a handful of first-party titles. In November of last year, 50 new games came to the service with Microsoft adding a steady line-up of titles since.

The xCloud beta has since come to other regions, including Canada and Western Europe. The service was initially limited to console, but Microsoft has also started testing it on PC, too. 

Microsoft announced Xbox Game Pass Ultimate back at its E3 2019 conference. This subscription costs a bit more than the base version, but comes with extra functionality, such as Xbox Live Gold and the ability to play titles from the subscription service on both Xbox and PC.
