Hey all,

Response to the Biotech release has been amazing! Just here to let you know that we've put out two hotfix updates so far. Change logs are below.

We're watching and gathering issue reports across forums, Discord, and reddit and will continue to fix critical issues as they're discovered. Less-critical things will be left for slower updates later - it's important to stick to essentials for hotfixes, because it's easy to break one thing while fixing another and maintaining stability is our top priority now.

If you're willing to help report or investigate issues, please join the RimWorld Official Development Discord server[discord.gg]. Thanks to all those who took the time to report issues.

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.

Key among those is a new way to play with Ideology content active, but without actually running the ideology system. The ideology system is great for players who want to do something different, but it could be overwhelming for someone on their first game or who just wants to relax. This new option allows running the game without the complexity of the ideologion system, but with almost all the Ideology content active, including the biosculpters, ancient complex quests, Gauranlen trees, public executions, and more. (Some buildings like skullspikes and loudspeakers are still buildable despite not doing much without ideoligions active - they make nice visual flair if you want them.)

We've also reworked how a few pieces of Ideology work to make common ideoligions reduce microman... Read more

Hey everyone, just a quick note about the Steam Deck release and RimWorld.

RimWorld works on Steam Deck as it is now, but there are a number of UI issues and some general jankiness we intend to solve with an update.

Our developer who was working on this lives in Ukraine. After delays getting the Deck to him, the current situation there means he won't be making progress any time soon.

Our tech lead Piotr Walczak is taking over Steam Deck integration efforts. However, we probably won't have an integration patch out until after the Deck is released.

To those of you excited to play RW on the Deck - We are excited too! Please look forward to updates that should solve issues you might find. If you can, consider waiting for the update before you dive in. We want the experience to be as great as possible and we're working to make that happen.

We also welcome reports of any issues on the official dev Discord ... Read more

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 we did make some analysis tools and I tried to adjust things to solve it. Unfortunately, I missed the true issue and the problem persisted. After some recent feedback from ... Read more

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 much lower, especially for large colonies.

We also reworked caravan formation to make it faster and more fluid. The archonexus restart sequence got some love so it's clearer and better-tuned. Finally, there's also a bunch of smaller improvements - see the change list below.

This update was tested as compatible with all savegames and mods.

EDIT 3: The build is now live for everyone. Thanks to the mod authors of Doors Expanded for updating quickly!

Hey everyone! RimWorld update 1.3.3117 is now out. This one comes with a long list of new stuff and improvements. Full changelist is below.

Multi-ideo viability: One key thing I wanted to do with this update was make it more rewarding to have a colony with diverse beliefs. While it should certainly be possible to run your colony as an ideological monoculture, I always wanted it to be possible to claim the benefits of multiple belief systems at the cost of needing to take a wider diversity of needs into account. This would also make recruiting easier, since it wouldn't be necessary to convert everyone during the recruiting process.

We made several changes to achieve this goal.

Now, colonists can participate in rituals of other ideoligions, strengthen those rituals by their presence, and gain mood and other benefits from them. Big... Read more

Hello RimWorld players! I've just released RimWorld version 1.3.3101. This one comes with a long list of new stuff and improvements for the base game and both expansions. Full changelog is below.

Fluid ideoligions: The big feature in this update is fluid ideoligions.

You can start the game in a new mode where you define a simple, minimal ideoligion to begin with. Then, during play, you'll earn development points by completing rituals and taking actions that satisfy your beliefs.

With enough development points, you can reform your ideoligion to alter memes, styles, precepts, and everything else. You'll be able to build up the complexity and intensity of your belief system as the game progresses.

The original system with stable ideoligions also remains available, if you want to play a specific belief system from the start.

Compatibility: This update should be compatible with all savegames and mods.

Thanks: Thanks ... Read more

Hey everyone! I've just released version 1.3.3087 of RimWorld with a variety of improvements for the base game and both expansions. Full changelog is below.

The main visible feature in this update is tree replanting. You can extract a tree and move it around as an item. You can then replant it where you like. It'll die after 7 days if not replanted. Anyone can do this, but it should be especially useful for colonies who believe it's immoral to kill trees since now they can move trees out of the way of building sites.

This update should be compatible with all savegames and mods.

Thanks to everyone who helped us test it on the official development Discord server[discord.gg], and to everyone who has submitted bugs and constructive feedback. We're happy to have all this great information to use while improving the ... Read more

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 games as they get used to the game systems.

This update also significantly improves video memory usage, especially in heavily-modded games.

It is compatible with all saves and mods.

Hey all, another update! This one hits a lot of various points game-wide. See change list below.

It should be compatible with everything. Please let us know on the official dev Discord[discord.gg] if you have a problem and we'll get right on it!

We're continuing to collect feedback and improve everything we can. I much appreciate everyone who has helped out!

Change list:

- Having 1 or 2 colonists of a player's original ideoligion boosts conversion chance for that ideoligion and reduces it for conversions against that ideoligion. This is configurable in difficulty settings. This makes it easier to expand an ideoligion starting from just one person.
- When a pawn is connected to multiple gauranlen trees, they prioritize pruning the tree with the biggest difference between desired connection strength ... Read more

The release of Ideology and 1.3 have brought a massive surge of new players and new energy in the RimWorld community. It's awesome and slightly overwhelming. We've been hard at work translating feedback into fixes and improvements to try to make the best play experience possible, both in the short and long term.

To that end, there's currently a testing branch of the next update up on Steam's unstable beta branch. (Changelist below.)

We test these builds and take feedback directly on the official development Discord server. Anyone who is willing to help out should please join us there[discord.gg], try out the build and tell us what you find! Many thanks to all who have participated and all who join.

Just a quick PSA for all the modders out there valiantly updating their mods to 1.3.

There's no need to break compatibility with 1.2 while adding support for 1.3! It's quite easy to make a mod support multiple versions of the game, just by putting the old version's files in one folder and the new version's files in another.

If you want to be more efficient and share identical files between versions, you can do that too. You can even define your own custom folder structure for full control.

This document explains the details on how to do it: Multi-version mods in RimWorld[docs.google.com]

RimWorld - Ideology is available on Steam now!
Hello everyone! I’m Tia, an insect lover and spelopede sympathizer at Ludeon. Today, I get to share some big news!

Soon, we'll be releasing RimWorld update 1.3 with new free content and a variety of improvements including animal fences, breach raids, beards, and many quality-of-life improvements.

You can play 1.3 now on the Steam branch 1.3-preview. (To access it, go to your Steam library, right-click RimWorld and select "Properties", then select the BETAS tab and choose branch 1.3-preview. Restart Steam if needed.)

The beta is to give modders ample time to update, as well as help us fix those final bugs. As a reminder, RimWorld supports multi-version mods, so anyone should be able to continue playing 1.2 as long as they like and change over when desired, as long a... Read more
