Getting Started

Requirements and initial setup.

OMORI Community Enhancement Pack was finalized on 14 October 2024.

The pack still works, but it will no longer receive updates or support. Information on these pages may be outdated.

See the Final Release FAQ for more information.

Requirements

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

OMO CEP for Windows

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

  • *Windows 10 will no longer be supported October 2025

• 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.

OMO CEP Lite for Steam Deck

• A Steam Deck running the latest version of the SteamOS software

• An unmodified installation of OMORI from Steam

• A connected keyboard and mouse (wired or wireless)

• At least 1 GB of free space on your system

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.

Windows 11

• 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.

Windows 10

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

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

• Check the box labelled File name extensions if it is not checked already.

Steam Deck

File extensions are automatically shown in SteamOS Desktop Mode.

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!

Sounds good. Move on to the next page.

Some of the mods you've already installed may not be compatible with OMO CEP.

You will need to reset your game files before continuing.

• Open your OMORI\www folder.

• Back up the save folder inside by copying it to another location on your computer.

• Delete every folder inside the www directory except the folder named save.

Make sure not to delete the save folder!

It contains your save data, and OMORI does not have cloud save support!

• Once you're done, move on to the next page.
