Amazon is expanding its cloud gaming efforts with an official U.S. launch of its Luna platform. The service, which has been in an “invite-only” beta state since its soft launch in the fall of 2020, is now available for anyone in the mainland U.S. to sign up, with various subscription options.

Luna differs from competing cloud gaming platforms from Google, Microsoft and Nvidia in that it follows a cable TV model, offering channels with a bundle of games for a flat monthly subscription fee. Luna does not, however, let you play games you’ve bought elsewhere, as Nvidia’s GeForce Now does, and doesn’t let you purchase games or play free titles, as Google Stadia allows.
