Amazon's up-and-coming cloud gaming service, Amazon Luna, is now available in the US for select Fire TV devices, without the need of an invitation.
Initially, Amazon Luna required an invitation to access the platform. According to Amazon, this has changed, with Amazon Luna becoming free to try in the US, and the Amazon Luna Controller becoming available to all for purchase.
According to Amazon Luna's FAQ, you can request an invitation on Luna's official page on Amazon, or you can download the app on a supported Fire TV device. You will need to be in the United States to access Luna (excluding Alaska, Hawaii, and US Territories).
You also require a compatible controller to play Amazon Luna, such as a DualShock 4, Xbox One Controller, or the Luna Controller.
Amazon Luna utilizes a subscription-based "channel" system, much like cable, for its games. Signing up for Luna will give you a 7-day trial of the Luna Plus channel. After the trial, you will be charged $5.99 a month. The Luna Plus channel is a growing library of games that currently include games such as Control, GRID, Metro Exodus, and more.
You can also subscribe to the Ubisoft Plus channel, which will give you access to a handful of Ubisoft games such as Assassin's Creed Valhalla.
Outside of the Fire TV devices, you can request beta access to play the game on Windows, Mac, Android, and iOS.
