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 Information on these pages may be outdated.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.
omo.cep.one will go offline on 31 December 2027.
OMO CEP will still be available for download on mods.one. A complete archive of this site is now included with the project.
Requirements
We do not provide support for pirated copies of the game.
A registered installation of 64-bit Windows 11 or newer
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?

Mods in the pack can be enabled or disabled
More mods can be installed from mods.one

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.
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.
File extensions are automatically shown in SteamOS Desktop Mode.
Move onto the next step!
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!
Next Steps
Have you modded OMORI before?
You're all set! Move on to the next page.
Steam and OMORISounds 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.
