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.

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 fin... Read more

Hi there!

RimWorld's 1.4 content update is now available! It adds cross-expansion integration with new Ideology precepts that link to Biotech, gene-modding and inheritance improvements, diplomatic reactions to pollution dumping, polux tree seeds, tribalwear for kids, and many other miscellaneous changes.

In a previous announcement, Ty covered the juicy details of this update. That same announcement has been shared below, as well as the changelog with our latest rounds of testing.

Thanks to everyone who helped us test this update. The community goes above and beyond with feedback and reports, and it genuinely helps us get these updates out so quickly. We've also tested the update for savegame and mod compatibility. If you’d like to help test our updates in the future, please join the official RimWorld Development Discord[discord.gg].

If you want to keep playing on the previous version of 1.4, you can use the Steam beta branch "version-1.4.3542". To do this, r-click RimWorld in the Steam li... Read more

Hi everyone, the unstable branch has just received a new patch. We've gotten some great feedback from the community on our 1.4 content update. Latest changelog below.

The 1.4 content update has cross-expansion integration, gene-modding changes, player-made xenotypes in the world, and lots of other improvements. Read about it here!

Are you interested in helping us test the 1.4 content update? We'd love it if you could share any bugs or issues you find in the official RimWorld Development Discord[discord.gg].

To get access to the unstable branch, go to your Steam library, right-click RimWorld and select "Properties", then select the BETAS tab and choose branch unstable. Restart Steam if your game does not automatically update.

Thanks everyone!

Hi everyone - Ty here.

So behind the daily bug fixes, we’ve been working on a 1.4 content update with more substantial improvements and more stuff to play with.

This content update comes with cross-expansion integration between Biotech and Ideology, improvements to gene modding and gene inheritance, changes to pollution management strategies, and extra polish for various gameplay elements and UI.

It’s nearly done and is now up for testing on Steam’s unstable beta branch. Everyone’s invited to test it, and we’d love it if you could share any bugs or issues you find on the official RimWorld Development Discord[discord.gg]!

To get access to the unstable branch, go to your Steam library, right-click RimWorld and select "Properties", then select the BETAS tab and choose branch unstable. Restart Steam if your game does not automatically update.

Hi everyone. Valve has recently released their new recommended currency conversions for Steam games and many game studios are beginning to implement these.

We are planning to follow Valve’s recommendations and update some of our non-USD price conversions. (Note that none of our base USD prices will change - this is only about updating currency conversion rates.)

In most cases our prices will remain lower than what Valve recommends. The major currencies will generally see increases of 2-10% - this includes Euros, Chinese yuan, British pounds, Canadian dollars, Australian dollars, Japanese yen, and Korean won. Biotech will change less than other products, since its prices are already more up-to-date.

Some currencies stand out since Valve is recommending larger changes. In Brazilian reals, Steam recommends 101.99 BRL for RimWorld; we are planning 79.99 BRL. In Polish zloty, Steam recommends 161.99 PLN; we are planning 149.99 PLN. In Russian rubles, Valve now recommends 1200 RUB; we’re plann... Read more

Hi everyone!

We’ve been pushing updates with hotfixes and improvements for 1.4 and Biotech over the last week. We tweaked fixes to make them more mod-friendly and have been collaborating with modders to make updates more seamless for everyone. I’ve added a cumulative changelog below for your enjoyment that covers aaaall of those updates.

Other recent changes for 1.4:

• Update 1.4.3525 hotfixes some issues
  
• Recent patches for 1.4
  
• [Edit] We're working on a 1.4 content update!

Here are some highlights:

- Mechanoids: Labor mechanoids have more work types, are more accessible, and tunnelers have more armor. Fabricors now know how to butcher and cook, and they’ll be serving up hot meals for your colonists in no time. You can also leave body disposal to your lifters who can work the crematorium themselves. Cleansweeper mechanoids are available through “basic mechtech” research instead of “standard mechtech”, and tunneler mechanoids are beefier to help with melee combat.

- Genes: The time required to e... Read more

The RimWorld - Biotech expansion is out! This large-size expansion revolves around babies and child-raising, genetic modification, and the ability to control mechanoids.

Here's the trailer:


RimWorld update 1.4 is also released! We described the 1.4 changes in detail in this announcement. Or you can read the changelog here[docs.google.com].

Compatibility:

• Unmodded savegames from 1.3 will load in 1.4.

Hey everybody! I'm Will, a designer working on RimWorld - Biotech. In our last blog post, we covered how Biotech lets you build mechanoid colonies run by high-tech mechanitor overseers. You can also read the original 1.4 update and Biotech announcement here.

Today, we’ll look at combat mechanoids, commander mechanoids, and pollution! New combat mechanoids open up many avenues for offensive and defensive tactics, and special super-dangerous mechs hold the key to greater power for your mechanitor. Mechanoid production also generates pollution which has its own unique challenges and uses.

Later this week we’ll take a look at reproduction, children, vatgrowing, and genetic modifications.
