How to install non-Steam games on Steam Deck

Valve offers thousands of PC games compatible with the Steam Deck through the official store, but that doesn’t mean there aren’t other games it can handle. Some titles never make it to Steam, whether due to licensing difficulties, platform exclusivity, or anything else. You can easily install non-Steam games on Steam Deck with a small amount of tinkering behind SteamOS, so let’s get started.

How to install non-Steam games

Before starting, any apps or games you install outside the official Steam Deck store will be on the internal storage, not your microSD card or any other external drives. Be sure to check you have enough space on the primary eMMC SSD, the size of which depends on which Steam Deck model you chose (64GB, 256GB, or 512GB).

  1. Hit the left-side STEAM button to open the quick menu.
  2. Navigate down the list to highlight and select Power.
  3. On the power menu, navigate to and select Switch to Desktop.
