I’ve set the development version of Alpha 15 on the ‘unstable’ branch in Steam. If you’re willing to risk some bugs and imbalances you can give it a shot! Just right-click RimWorld in the Steam library, open Properties, go to the Betas tab, select the ‘unstable’ branch, and restart Steam.

The final version will be different from this. Language and player creative content still need to be updated, problems will be fixed, and the build will be compiled in the non-development way (which will make it run faster). However, all the main changes are there now!

Note that this version isn’t compatible with Alpha 14 saves or mods. You’ll want to deactivate your old mods, and you can’t load your old saves.

Modders can/should use this opportunity to prep for the new update!

I’m soliciting all feedback about the new version in this forum thread. I’m especially interested in balance/play feedback about the drugs system and tutorial. Bugs should please be reported in the Bugs forum.

I could also really use some savegames for recording the release video on! I’m really just looking for natural colonies – not some weird fancy artwork. Ideally, with a drug production operation. If you’ve got a savegame like this, please zip it, put it on Dropbox or another file hosting service, and drop the link in the feedback thread. Thanks all.

EDIT: Unstable branch updated to fix an issue that made treatments useless on various diseases (causing infections to be 100% deadly).
