RimWorld · Update 1.7 · unstable beta
A test release moves RimWorld to the Waylith Engine. The developer reports broad save and mod compatibility, but this release is available on Steam’s unstable beta branch. It is optional, and existing mods still need review.
Installation
- Close RimWorld and back up saves, configuration and your current mod list.
- Read the original announcement and beta requirements before opting in.
- In Steam Library, right-click RimWorld, open Properties, select Betas and choose the branch named "unstable".
- Let Steam finish updating, then test a copied save with mods disabled before reviewing mod compatibility.
Removal · recovery
- Close the game, open Steam Properties and Betas, and leave the branch named "unstable" to return to the normal release.
- Use backups and copies when restoring saves or mod settings. Verify installed files if needed.
