Hello everyone!

It’s Tia - I’m back with update 1.3.3326 which brings full support for RimWorld on Steam Deck!

Before I get into the update, I wanted to share that our developer who was living in Ukraine is now safe in Germany. He’s staying with one of our former team members and we're doing what we can to help him …
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 …

Hello everyone,

Unfortunately, we've just been informed that RimWorld has just been made unavailable for new purchases by Australian customers on Steam.

This does not seem to affect existing owners - it only prevents new purchases. Anyone who already owns the game is still be able to play, …
Hey everyone, it's time for another update!

This update fixes a variety of bugs and includes a number of changes that should make the ideoligions system less restrictive and more flexible.

Hey everyone - here's a new update for RimWorld for all of you!

This wide-ranging update makes a variety of improvements - see the full changelog below.

One critical adjustment is in the proportion of different raid strategies. Previously, mechanoids were using breach raids far too often. I've been seeing feedback about this for a while, so in previous updates …
Hello everyone! I'm happy to announce a new update for RimWorld and all expansions.

The biosculpters got a focused redesign. Colonists can now automatically do their own age reversal, and initiating a biosculpting cycle takes 1 step instead of 3. There's also less incentive to do weird things like deconstruct and reconstruct the biosculpter. Overall the micromanagement burden should be …
EDIT 3: The build is now live for everyone. Thanks to the mod authors of Doors Expanded for updating quickly!

Hey everyone! Today's update adds a new ideoligion setup screen with a variety of preset patterns for ideoligion generation. The idea is to avoid overwhelming the player with details if they just want to play.

We also added the ability to play the game with an ideology matching classic RimWorld. This is a good idea for the player's first few …
