Game Pass is on Steam Deck using an Edge browser beta
A new beta for Microsoft Edge lets Xbox Cloud Gaming run in-browser on a Steam Deck, letting you stream Game Pass games in-browser directly to the mobile gaming PC. By installing Microsoft Edge (for Linux) and running it on your Steam Deck using Linux, then upgrading to a new beta, you can do this pretty quickly.
You can head to the Xbox Cloud Gaming Beta website to see what works there and what can be streamed. I’d like to know in the comments what you’re trying here and how well it works, since my personal Steam Deck is in wave 2 and I’m grumpy about it.
You can read more about the beta in a dedicated post on Microsoft’s Xbox Cloud website or in a shorter Reddit post from the Microsoft Edge Community Team. Microsoft even created tidy banners and images to make it look pretty.
This working stuff is in addition to the Xbox Game Studios stuff that is already on Steam and should work on Steam Deck from the start. Here’s a list of games from Xbox Game Studios that work well on Steam Deck, as well as those that don’t work due to anti-cheat: Psychonauts, Hellblade, Battletoads, and Max: The Curse of Brotherhood are all verified. Sea of Thieves, Forza Horizon 5, Forza Horizon 4, Quantum Break, and State of Decay: YOSE are all playable, but not yet verified.
Microsoft is doing everything possible to support Linux! Try saying that to an early 2000s nerd. What world do we live in.
