Finally, today we’re announcing that this September, in supported countries, we’re bringing Xbox Game Pass and Project xCloud together at no additional cost for Xbox Game Pass Ultimate members. With cloud gaming in Game Pass Ultimate, you will be able to play over 100 Xbox Game Pass titles on your phone or tablet. And because Xbox Live connects across devices, you can play along with the nearly 100 million Xbox Live players around the world. So when Halo Infinite launches, you and your friends can play together and immerse yourselves in the Halo universe as Master Chief—anywhere you go and across devices.

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