While **NINJA GAIDEN 4** is officially Steam Deck Verified, players running the game on Desktop Linux have encountered significant issues. Fortunately, Valve has addressed these problems with a recent update.
Valve developer Pierre-Loup Griffais announced on Bluesky:
> “A Proton Hotfix has been deployed for the NINJA GAIDEN 4 hang issue on desktop.”
Looking into the related GitHub report, many users experienced frequent game freezes. To resolve this, Valve has now enabled the Proton Hotfix by default for NINJA GAIDEN 4.
