Microsoft’s Xbox One game streaming service, Project xCloud, will get a public preview test in October, letting select testers play games like Gears 5 and Halo 5: Guardians on phones and tablets.

The public preview of Project xCloud will initially be limited to players in the United States, United Kingdom, and Korea. Halo 5: Guardians, Gears 5, Killer Instinct, and Sea of Thieves will be playable as part of the preview, and Microsoft says it will add more titles over time. Testers won’t need to own the Xbox One games available during the Project xCloud preview in order to play them.

Players interested in taking part in the Project xCloud public preview can register for the closed beta based on their country. Microsoft says it will roll out invitations in a phased approach, starting with a “small number of participants,” and opening it up to more players over time.

Project xCloud’s public preview test will initially be limited to Android devices running Android 6.0 or higher with Bluetooth 4.0. Participants will also need a Microsoft account and a Bluetooth-enabled Xbox One wireless controller. Project xCloud will be compatible with WiFi and cellular networks, and Microsoft says it’s working with a number of cellular providers worldwide: SK Telecom in Korea, T-Mobile in the U.S., and Vodafone in the U.K.

Microsoft unveiled Project xCloud in 2018. The streaming platform aims to let players enjoy Xbox One games on mobile devices from the cloud, and will eventually let players stream their games from their own Xbox One consoles.

“Public preview is a critical phase in our multi-year ambition to deliver game streaming globally at the scale and quality of experience that the gaming community deserves and expects,” said Kareem Choudhry, corporate vice president for Project xCloud, in a statement. “It’s time to put Project xCloud to the test in a broader capacity, with a range of gamers, devices, network environments and real-world use-case scenarios, and this is where you come in. At Xbox, we’ve made it a priority to engage with all of you to help in the creation process. We now want you to play with us and share your feedback on Project xCloud so we can iterate and improve, week after week. Join us, have fun playing, share your stories and feedback, and be part of the journey.”
