RimWorld free update 1.1 and Royalty expansion released

Posted February 24th, 2020 by Tynan Sylvester

Two big pieces of news today!

Free update to version 1.1

RimWorld’s free 1.1 update is now live for all players! This update has been on the unstable branch for a week to smooth the transition for mods, and now it’s the standard branch for everyone.

To see the full change log for this update, look at the original 1.1 announcement here.

RimWorld – Royalty released

RimWorld’s new expansion RimWorld – Royalty is available!

See the full description and buy it at:

The expansion includes a new system for nobles and titles, psychic powers, mechanoid combat structures, quests and rituals, luxurious palaces, Imperial technology, and new music from Alistair Lindsay.

Through all of RimWorld development from 2013 to its release in 2018, our team size hovered between two and three developers. Since the game’s release, we’ve been scaling up. Now we’re at seven developers, which has allowed us to work on multiple projects in parallel. This is how we’ve been able to commit resources both to improving RimWorld’s core and adding new free content, as well as developing a rich expansion that opens up new kinds of gameplay.

Technical details

If you’re playing without mods: You’ll be able to update and continue playing on the new version without interruption.

If you’re using mods that haven’t added support for 1.1: You can continue playing version 1.0 as long as you like by using the version-1.0 beta branch. To access it, right-click RimWorld in your Steam library list, click Properties, then select the ‘betas’ tab. Select ‘version-1.0’ from the drop-down list. You’ll want to change this back to ‘default’ eventually.

For modders: We did a lot of work before 1.0 and in this version to make updating as painless as possible. There’s a guide to updating mods to 1.1 included in the game files, called ModUpdating.txt. The excellent modder Brrainz has also written a separate online guide here – thanks to him! You can also get live help with modding on the RimWorld Discord server.

The game now includes a system for handling multi-version mods, so there is no need to make multiple Workshop items or break old mod uploads by updating them in-place.

We will be carefully watching for critical bugs and fixing them! If you find anything, please post about it on the Ludeon bugs forum.


Big thanks to the developers who worked on 1.1 and this expansion: Piotr Walczak, Kenneth Ellersdorfer, Igor Lebedev, and Matt Ritchie. Thanks to Oskar Potocki both for his new art made just for us, and for providing his animal art. And I have to thank the volunteer modders, testers, and translators who helped out: Haplo, Brrainz, Pheanox, Dubski, Jaxxa, alphaBeta, Diana Winters, XeoNovaDan, someonesneaky, Mehni, RawCode, and many others. Thank you.
