[2022] Biotech expansion and update 1.4 available now!

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

Get it now on the Biotech Steam page!

To celebrate the release, RimWorld and the Royalty expansion are 10% off.

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.
  
• Many mods have already been updated by wonderful modders during the 1.4 preview over the last few weeks. However, some are not yet updated and won't work on 1.4.
  
• If you want to keep playing version 1.3, please use Steam beta branch "version-1.3-latest". To do this, r-click RimWorld in the Steam library, go to properties, open the betas tab, and select the version from the dropdown.
