UpgradeLib

How do I install UpgradeLib?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Subterranauts all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download UpgradeLib safely?

From the author's own page on GitHub, which is where the data here is synced from. IndexGG never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.

Which Subterranauts versions does UpgradeLib work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old mod with no declared version as untested on modern Subterranauts.
