Microsoft has been teasing it for a while, but Xbox Game Pass Ultimate Cloud Gaming (previously known as xCloud) will be entering limited beta testing starting tomorrow! The limited beta is potentially open to any Xbox Game Pass Ultimate subscriber, although a limited number of invites will be sent out. You get more details, below.

Starting tomorrow, we’ll begin sending out invites to select Xbox Game Pass Ultimate members to start testing the Xbox Cloud Gaming limited beta for Windows 10 PCs and Apple phones and tablets via web browsers. We’re launching xbox.com/play where invitees can play over 100 Xbox Game Pass titles through Edge, Google Chrome, or Safari. Offering cloud gaming through the browser and having a simplified, universal landing page presents a great opportunity to make cloud gaming approachable to more players in more places over time.
