Starting tomorrow, Microsoft will send 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.

According to Xbox Wire, they will also be launching this official website 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.

They will continue to send more invites on a continuous basis to players in all 22 supported countries, evaluate feedback, continue to improve the experience, and add support for more devices. They’re planning to iterate quickly and open up to all Xbox Game Pass Ultimate members in the coming months so more people have the opportunity to play Xbox in all-new ways.

Those who receive an invite will only require a compatible Bluetooth or USB-connected controller or can use custom touch controls for more than 50 games to start playing and testing. In the early stages of the beta, Microsoft will be focusing on fine-tuning features and creating a consistent experience across platforms, while making sure games are running their best.
