(Telecompaper) Amazon has unveiled a new cloud gaming platform called Luna, its rival to Microsoft's xCloud, Sony's PlayStation Now and Google's Stadia. The service takes the subscription model of Prime Video combined with the scale of Amazon Web Services, allowing subscribers to instantly play more than 100 Luna games on their favourite devices without lengthy downloads or updates, expensive hardware or complicated configuration. It will be available in the US from next month at an "introductory price" of USD 5.99 a month on Fire TV, PC, and Mac as well as on web apps for iPhone and iPad, with Android coming soon. Early access invites are already open.
