Getting Started

Requirements and initial setup.

Requirements

We do not provide support for pirated copies of the game.

  • A registered installation of 64-bit Windows 11 or Windows 10

  • An unmodified installation of OMORI from Steam

  • At least 1 GB of free space on your drive

The Microsoft Store / PC Game Pass version of OMORI is not supported.

It uses a different engine that doesn't let us add plugins.

What are the differences between OMO CEP and OMO CEP Lite?

OMO CEP

  • The complete OMORI modding setup for Windows

  • Includes over 25 enhancement mods

  • Includes the OneLoader mod loader

  • Mods in the pack can be enabled or disabled

  • More mods can be installed from mods.one

OMO CEP Lite

  • The all-in-one OMORI modpack for Steam Deck

  • Includes all of the enhancement mods in OMO CEP for Windows

  • OneLoader is NOT included - mods directly replace game files

  • Mod loadout CANNOT be customized

  • More mods CANNOT be added

Show File Extensions

By default, Windows Explorer hides the extensions of file types it recognizes (.EXE, .PNG, etc.). It's important that these be visible when setting up mods or asking for support, so we will make sure Windows always shows file extensions for all file types.

  • Open a File Explorer window (it doesn't matter where).

  • Click the View button at the top of the window.

  • Click Show > File name extensions.

Download OMO CEP

If you've already downloaded OMO CEP, skip this step.

  • Open the page for OMO CEP at mods.one/mod/cep.

  • Scroll to Available releases at the bottom of the page and click the download arrow next to either OMO CEP for Windows or OMO CEP Lite for Steam Deck.

What's mods.one?

mods.one (formerly OmoriMods) is the fan-made hub for OMORI mods.

If you're setting up OMO CEP for Windows (and if you're okay with seeing unmarked story spoiilers), this is where you can go after you're done to find even more cool mods!
