PC games giant Valve is bringing its SteamOS operating system to third-party hardware. In a blog post, the company said that its software was powering Lenovo's Legion Go S console (pictured), which itself was announced at the CES 2025 trade show.
There's also a Windows-powered variant, too, because the tech firm is seemingly hedging its bets. This is seemingly the first non-Steam Deck hardware that is using SteamOS with more to come. "We built this operating system to provide a seamless user experience optimised for gaming, while retaining access to the power and flexibility of a PC," Valve wrote. "SteamOS is the same operating system we run on Steam Deck, and the team is making updates to ensure it fully supports the Lenovo Legion Go S and provides the same seamless experience customers expect. "In addition, the same work that we are doing to support the Lenovo Legion Go S will improve compatibility with other handhelds.
Ahead of Legion Go S shipping, we will be shipping a beta of SteamOS which should improve the experience on other handhelds, and users can download and test this themselves.
