Where Does Limbus Company Store Data on PC?
Limbus Company keeps client settings in one Windows registry key, while progress lives on your account's servers. Here is what is local.
Last updated
Limbus Company is the turn-based RPG from ProjectMoon, out since early 2023 and still one of the busiest free titles on Steam. Its PC setup is unusual in a way that trips up the usual save-hunting routine: the client writes local data to the Windows registry rather than to files in AppData, and your actual progress is account based.
That means there is no save file to copy between machines. What is local is client settings, and PCGamingWiki lists them under a single ProjectMoon registry key. On Linux the same key lives inside the game's Proton prefix.
Where Limbus Company stores this, by platform
HKEY_CURRENT_USER\Software\ProjectMoon\LimbusCompany
Client settings. Progress is not here; it follows your Limbus Company account, which links to your Steam login. Export the key with regedit before a reinstall if you want your options back, since a clean install starts fresh.
~/.local/share/Steam/steamapps/compatdata/1973530/pfx/
Steam Deck and Linux run the Windows client through Proton for app ID 1973530. The registry key above sits inside this prefix, reachable through the prefix's registry editor.
Frequently asked questions
How do I transfer Limbus Company progress to a new PC?
There is nothing to copy. Progress is tied to your Limbus Company account, which links to your Steam login, so signing in on the new machine restores it. Mobile versions cross save through the account merge system.
Why is there no Limbus Company save file in AppData?
ProjectMoon writes client settings to the registry instead of ini files, so the usual AppData hunt comes up empty. Your actual save state is on the servers. Check HKEY_CURRENT_USER\Software\ProjectMoon\LimbusCompany for the local side.
Does reinstalling lose my Limbus Company settings?
Local options can reset because the registry key is removed or rebuilt. Progress is safe on your account. Export the key first if you would rather keep your window, audio, and language options instead of redoing them.
