Lenovo Legion Go S Becomes First Third-Party Handheld Feature SteamOS

The new device, launching in May 2025, combines Valve's gaming-focused SteamOS with upgraded hardware to challenge the Steam Deck.

Lenovo's Legion Go S will be the first non-Valve handheld gaming device to run SteamOS, offering a streamlined gaming interface similar to the Steam Deck.
The SteamOS version of the Legion Go S is priced at $499 and features the AMD Ryzen Z2 Go processor, 16GB of RAM, and 512GB of storage.
The device will also be available in a Windows version, launching earlier in January for $729, with additional configurations releasing in May.
Key hardware upgrades include a higher-resolution 1920 x 1200 LCD screen with a 120Hz refresh rate and optional trigger stops for shorter pulls.
Valve confirmed Lenovo is currently its only partner for SteamOS handhelds, with no other third-party devices announced at this time.
