Amazon Luna, the cloud gaming service that can be played through Fire TVs, phones, computers, tablets, and other devices, is having a big day of new announcements and one of those announcements is the addition of a new Prime Gaming Channel to Luna which allows Prime members the ability to play a selection of games completely for free. Each month, new free games will be rotated in starting with 4 games today and a fifth game being made available in about a week. There’s nothing to sign up for. Just launch the Luna app or head to the Luna site through a browser and start playing. You don’t even need a physical game controller thanks to a new virtual controller options.

To kick off the free games on Luna for Prime members, Amazon is providing access to the games Devil May Cry 5, Observer: System Redux, PHOGS!, and Flashback for the entire month of March. Additionally, starting on March 8, you’ll also be able to play Immortals Fenyx Rising. Note that access to Immortals Fenyx Rising for free will not last for all of March and will on March 14.

If you haven’t tried Amazon Luna yet, and are a Prime member, here’s your opportunity to give the service a try without paying anything or signing up for any free trials. The service is now open to all US residents and is compatible with Fire TVs, Fire tablets, Windows PCs, Chromebooks, Macs, iPhones, iPads, and Android phones. If you don’t have a physical controller to use, you can use your phone as a virtual controller.
