Hi,
I’m looking for help specifically with installing FCS (Field Creators Studios) mods for Subnautica on Linux. I’m using the Epic Games version through Heroic Games Launcher.
To be clear up front: general modding is already working. Subnautica runs fine, and BepInEx loads correctly. What I’m missing is a proper understanding of where FCS mods are supposed to go and how their folder structure should look. Right now, I just want to make sure I’m placing the right files in the right directories (so it works lol)
I’m not looking for help with:
Getting Subnautica to run
Setting up Proton/Wine
Installing BepInEx itself
I only need guidance on:
Correct placement of FCS Alterra Hub
Correct placement of individual FCS mods
What a working FCS folder structure should look like
Any differences to be aware of when using the Epic Games version
System details, in case they help 🙂
OS: Fedora Linux 43
Launcher: Epic Games via Heroic Games Launcher
Wine/Proton: GE-Proton-latest
Game install path:
/home/Arniee/Games/Heroic/Subnautica
Wine prefix:
/home/Arniee/Games/Heroic/Prefixes/default/Subnautica
Game status:
Subnautica (Epic Games version)
Runs perfectly vanilla through Heroic/Proton
BepInEx loads when running without mods + other mods work
If anyone has successfully installed FCS mods on Linux (especially with Epic + Heroic), I’d really appreciate a short step-by-step explanation or even just a folder tree example showing how the mods should be laid out.
Thanks in advance 🙂
