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.

Valve shared some welcome news about running SteamOS on devices beyond the Steam Deck or the officially licensed Legion Go S model.

The Steam Deck has been the biggest PC gaming hardware story of the last few years. So it’s no surprise that the idea of running SteamOS (perhaps the most celebrated component of that machine) on other handhelds like the Legion Go S is also a big deal.
