Building up a settlement on the go is going to be a reality soon for RimWorld fans, as a fresh Beta version is now available and ready for testing with the Steam Deck.
Planned to release in full on April 6, they're giving mod creators a little extra time to prepare as it's upgraded a lot of the internals for the Steam integration so quite a few mods could break with this Beta. They said everything but a few mods should work, and you can test by opting into the "steam_deck" Beta branch (no password).
"The update focuses on Steam Deck changes and improvements. The UI changes make it easier to read on-screen text and type with the Steam Deck keyboard, and menus look a lot better. The controls make more sense now with improved scrolling, zooming, time control, and touch screen navigation. Overall, playing RimWorld on Steam Deck should be a lot smoother with more intuitive controls. There may be more changes on the way to get RimWorld a “Verified” status for Steam Deck." — Ludeon Studios

Even though it's a native Linux game, Valve tested compatibility for this one and set it to Proton 7.
