Fields of Mistria mods are community-made. MOMI installs compatible mods, while multiplayer remains a separate community mod rather than an official game mode.
Download MOMI and mods
Start here. You need MOMI first, then a compatible mod file.
- Get the installer: Download MOMI from its GitHub Releases page. Open the newest release and choose the installer for your platform.
- Browse community mods: Open the Fields of Mistria page on Nexus Mods. Open a mod page, read its requirements and game-version note, then use its manual download.
- Set up community multiplayer: Open the Fields of Mistria Multiplayer Mod page. Read its relay and host instructions before inviting another player.
Download the mod archive, extract it, and put the extracted folder in mods. MOMI cannot install the .zip itself.
MOMI at a glance
MOMI means Mods of Mistria Installer. It reads compatible, extracted mod folders and installs them into the game. Use its current release, then run it again after a Fields of Mistria update to reinstall the mods in your folder.
MOMI is community software. Back up a save before changing its mod list, keep the game and every mod on the versions named by their authors, and download from the original project pages.
Install MOMI step by step
- Create a folder named
modsin the Fields of Mistria game folder, besideFieldsOfMistria.exeon Windows. - Download MOMI from the MOMI releases page, then run the installer and select Install.
- If MOMI cannot find the game, place the installer beside
Maybe.tomlin the game folder and run it again. - Download a compatible mod from its original author page. Extract it into
mods, then run MOMI again. - Launch the game only after MOMI lists the mod. After every game update, repeat the MOMI install step before launching a modded save.
On Steam Deck or another Linux setup, MOMI also accepts a mistria-mods folder in the home directory. Use the release that matches your platform.
Choose popular mod types safely
Cosmetic mods are the easiest place to start: they add visual options such as clothing or other appearance assets and are usually isolated from game logic. MOMI's documented format supports cosmetics through files in a mod's momi/cosmetics/ folder.
Gameplay mods change behavior through GML and MOMI's MMAPI framework. They can add more moving parts to a save, so read their dependency list, game-version requirement, and author notes before combining them with other gameplay mods.
The practical test for a good mod is not its download count. Pick a mod with a current compatibility note, a clear dependency list, and an author page that explains how to remove or update it. Keep your initial setup to one cosmetic mod or one gameplay mod, then expand only after each launch succeeds.
Fix MOMI folder and install errors
A MOMI-compatible mod must be extracted, and manifest.toml must sit directly inside its mod folder. The working shape is mods -> Mod Name -> manifest.toml. A double folder such as mods -> Mod Name -> Mod Name -> manifest.toml prevents MOMI from detecting it.
MOMI cannot install a .zip file. Extract the archive first. If it reports no compatible mods after extraction, open the mod folder and look for manifest.toml; a folder without that file is not a MOMI-compatible mod.
After a cosmetic mod installs but does not appear in an existing save, update MOMI, reinstall, and follow the acquisition instruction on the mod's author page. Some cosmetics use an in-game shop or another unlock path.
Fields of Mistria multiplayer status
Fields of Mistria is officially listed as a single-player game on Steam. The community Multiplayer mod is a separate project: it uses MOMI plus the mod's relay and setup instructions to create shared sessions. It is not an official online or local co-op mode.
Every player in a community session needs the same Multiplayer mod version and dependencies. Start on a fresh test save, keep backups of main saves, and follow the multiplayer mod author's instructions for host and relay setup. Read the dedicated Fields of Mistria multiplayer guide before inviting another player.
