Vivarium
This is a chart by Shayofc. As of 27 April 2026, this chart is actually not officially available yet. They posted it in the Lounge39 discord server (and is lost in the messages now), but it's not on Gamebanana or DivaModArchive. Shay gave me permission to port it over to Project Heartbeat. Thank...

Frequently asked
How do I install Vivarium?
Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Project Heartbeat all have to be on the same version, which is the usual reason a mod does not appear in game.
Where do I download Vivarium safely?
From the author's own page on Steam Workshop, 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 Project Heartbeat versions does Vivarium 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 Project Heartbeat.
