Microsoft has revealed more details today on its Project xCloud game streaming service, revealing that it's launching in beta with Xbox Game Pass Ultimate on September 15th - but only on Android devices for now.

As announced last month, Project xCloud will allow Ultimate subscribers to play "over 100 titles" via the internet on phones & tablets, and that list will be announced near launch - although you can see some of them below.
