Anyone with a Fire TV can sign up for Amazon's Luna game-streaming service now Amazon Luna is creeping up on Stadia when it comes to availability. The company has announced that the platform is now available for anyone interested who owns a Fire TV, departing from its initial invite-only approach to distributing the service. Luna still remains in its Early Access phase, though. New customers can download the Luna app on their Fire TV and sign up for a 7-day free trial without having to wait for approval. This broadens the service's availability and makes it much easier to get in on the action, especially if you already own a compatible Fire TV. Amazon has also announced that its controller can now be purchased without an invitation on Amazon.com/LunaController. But you can just connect your existing compatible Bluetooth controller to your Fire TV if you already have one.
