SteamOS was always supposed to be bigger than Valve’s own Steam Deck, and 2025 is the year it finally expands. Not only will Lenovo ship the first third-party SteamOS handheld this May, Valve has now revealed it will let you install a working copy of SteamOS on other handhelds even sooner than that.

Pierre-Loup Griffais, one of the lead designers on the Steam Deck and SteamOS, tells me a beta for other handhelds “is slated to ship after March sometime,” and that you might discover the OS just starts working properly after that happens!

Griffais and his co-designer Lawrence Yang would not confirm which handhelds might just start working, though there are some obvious candidates: the company confirmed to us in August that it had been adding support for the Asus ROG Ally’s controls.

Also, quite a few PC gamers have also discovered that Bazzite, a fork of Valve’s Steam Deck experience that I loved testing on an Ally X and vastly preferred to Windows, also works wonderfully on the Lenovo Legion Go. There still aren’t that many handhelds out there at the end of the day, and I would think Valve would take advantage of work the Linux gaming community h
