Steam lists the DERELIKT Demo's Steam Deck compatibility as Unknown, alongside Full Controller Support in a separate part of the store page. If you're checking whether the built-in Deck controls are supported, look for both labels. The controller feature entry shows that the demo supports gamepads, while the Deck entry gives Steam's handheld compatibility status.

What the controller listing tells you
Steam names Xbox and PlayStation controllers for the demo. The feature list gives no button-by-button mapping for the Deck, so a specific default layout remains unconfirmed. If you try the demo, check which prompts you get when you first move, aim, and interact. Then check the pause menu and inventory, since you'll need those controls alongside movement and shooting.
If you change the controller layout during your own test, keep track of the difference between the prompts you saw initially and the inputs you remapped. That helps if you later return to the default layout or compare your results with another player's.
Check the full game separately
The demo has its own Steam listing and its own compatibility field. For the release version, open its store page and look for Steam Deck Compatibility and controller information there. The full-game listing reviewed for this guide was still pre-release. Use the live listing for any later rating or feature updates. Official DERELIKT full-game store page
