Hey everyone. RimWorld turned ten years old on November 4, 2023, and it's just in time for the 2023 Steam Awards. You can nominate RimWorld under the "Labor of Love" category!

It's been ten years of content from the Kickstarter, alpha, beta, and Steam greenlight days, plus game updates, lore, fanart, videos, streams, memes, Royalty, Ideology, Biotech, Steam Deck, console release, and much more I didn't cover. We're really proud of RimWorld and our community. Here's to more RimWorld!

The Steam Autumn Sale just started as well, and we're running discounts on RimWorld, Royalty, and Ideology until Nov 28.

Happy ten years!
- Ty & the Ludeon team

Hello everyone, Tynan here.

Good news today: We're reducing prices for RimWorld and its expansions in multiple non-USD currencies.

The prices were already below Valve's recommended prices in most cases (you can see the discounts here). This price reduction will increase the discount even further.

The price reductions range from 3% to 15% and affect 7 different currencies. For example, in Canadian dollars, RimWorld will be reduced from $42.99 CAD to $39.99 CAD. See the full list below.

Hello, it’s Tia! I’m here to share a small update just before the holidays. ❄️️

Today’s update comes with a looong list of fixes. Loads of these were made with the help of our testers - a big ol’ hug and huge thank you for helping us squash those bugs! Now children are less likely to run headfirst into danger and bestowers will get the heck outta there if they’re breathing in poisonous gas. We also added a few tools to help out our modders and community translators do their thing. The changelog is below to read over.

If you want to keep playing on the previous version of 1.4, you can use the Steam beta branch "version-1.4.3563". To do this, r-click RimWorld in the Steam library, go to properties, open the betas tab, and select the version from the dropdown.

2022 was a wild and fantastic year for us at Ludeon Studios. We released RimWorld’s third expansion, Biotech, which brought babies and children, new mechanoids, the mechanitor, gene modding, and xenotypes to the game. We ran several Steam Deck betas and became verified - now people can play RimWorld anywhere, anytime! Our team grew in size with several incredibly talented individuals at the helm. Who knows what we'll get up to in 2023.

The RimWorld community has been with us at every step, and your voices make a difference and actually shape the game. So keep talking to us in the Discord! Please continue to share your feedback and fanart and memes and screenshots and videos and mods and edits with us.

Hi!

Fresh patch notes here. Today, we’ve got rebalanced quest rewards and some changes for genes and children, plus various bug fixes. The changelog is available below.

With the wide variety of items added over the past few expansions, it was time to revisit quest rewards. Our community's feedback and discussions on Reddit were especially useful!

We wanted to make sure that quest rewards were varied and rewarding throughout all stages of the game. This update reduces the frequency of some rewards and removes others, like double beds and slab beds. You’ll now see a greater variety of cool and valuable quest rewards including infinite chemreactors, techprof subpersona cores, vanometric power cells, psychic emanators, and more!

We also adjusted ancient complexes to occasionally contain high-value loot. Ancient complexes should feel exciting and rewarding when you finally reach the treasure and make a daring escape, so it made sense to add a wider range of interesting items. You can also find Biotech-specific rewards like genepacks, archite capsules, or deathrest capacity serums scattered throughout a complex.

Big thank you to our testers and dedicated community for helping us with these updates and giving us feedback! Join us on the official RimWorld development discord if you'd like to help test in the future. :)

Please don't hesitate to leave Biotech a review on Steam. (Expansions tend to not get many reviews!)
