Valve is making a notable shift with its portable gaming strategy as Lenovo debuted a new edition of its Legion Go gaming handheld that runs Valve’s custom operating system.

The Legion Go S is a streamlined PC gaming handheld and the first with SteamOS since Steam Deck; the Go 2 is a full sequel. The Legion Pro 7i gaming laptop also gets a silicon boost.

Lenovo is already announcing one new handheld (or two depending on how you’re counting) at CES 2025. However, that isn’t stopping the company from looking ahead to its next portable gaming device by teasing an early prototype of the Legion Go 2.

Lenovo showed off the Legion Go S, which will come in two different versions: a Windows 11 model and a SteamOS model, which is the first of its kind from a third-party manufacturer.

Valve worked with Lenovo to make it a reality — though there’s a Windows version, too.

Three new Lenovo Legion Go handhelds are inbound, including SteamOS model and a new OLED version armed with a Ryzen Z2 Extreme APU.
