Steam Deck support in mod compatibility testing

Posted March 16th, 2022 by Tia Young

Hi everyone, it’s Tia. We’ve released our Steam Deck update 1.3.3300 as a beta branch on Steam.
This update has full support for Steam Deck!

However, for that to work it has to use a new version of the Steamworks API, which will break mods that access Steamworks.

If you’re working on a mod that accesses Steamworks, please prepare to update to its new version to prevent breaking the game.

We are planning to release this version to everyone on Wednesday April 6 at around 5pm EST.

Players who want to use Steam Deck should also use this branch for now. Everything except a few mods should work.

To play this beta on Deck or PC: right-click RimWorld in your Steam library list, click Properties, then select the ‘betas’ tab. Select ‘steam_deck – Steam Deck update’ from the drop-down list. Your game should auto-update – if it doesn’t, restart Steam.

To share any feedback or bug reports from the beta, please join the Official RimWorld Development Discord.


Steam Deck Changes

In a previous announcement, we said support for the Steam Deck would be delayed until after the console’s release. Since then, our tech lead Piotr Walczak has been working hard to put together this integration update.

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.

We also fixed some sources of annoyance in the ideoligion configuration screen.

The full changelog is below.

Ideology Improvements

– Fix: Reforming a fluid ideo lists some precepts as “incompatible” when they actually are.
– Fix: Ability gizmos are still available for roles that have been removed via reformation.
