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.

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.

We're trying to keep savegames compatible with mods, but it is the unstable branch so there may be things that break.

Thanks everyone!
