Oxygen Not Included How To Install Mods Manually __link__ -

While the Steam Workshop makes modding Oxygen Not Included (ONI) a breeze, there are plenty of reasons to go the manual route. Maybe you’re using a version from the Epic Games Store, playing offline, or trying to use a specific legacy mod version that isn’t on the Workshop.

Whatever the reason, here is the definitive guide on how to install ONI mods manually. Step 1: Locate Your Mods Folder

Oxygen Not Included doesn't store its mods in the installation directory where the game files live. Instead, it uses your local user profile folder.

The path for Windows users is typically:Documents\Klei\OxygenNotIncluded\mods\ Inside this "mods" folder, you will see two subfolders:

Steam: This is where the game automatically dumps files downloaded from the Workshop. Do not put manual mods here.

Local: This is your target. This folder is reserved for mods you’ve created or downloaded manually.

Note: If the "mods" or "local" folders don't exist yet, simply create them yourself with those exact names. Step 2: Download and Prepare the Mod

When you download a mod manually (from sites like GitHub or forums), it usually arrives as a .zip or .rar file. Extract the files: Use a program like 7-Zip or WinRAR.

Check the folder structure: Open the extracted folder. You should see a file named mod_info.yaml and usually a mod.dll file.

Rename the folder: Ensure the folder containing these files has a clear name (e.g., "Manual_Speed_Mod"). Avoid using special characters or long strings of numbers. Step 3: Move the Files

Copy your extracted mod folder and paste it directly into the Local folder you located in Step 1.

The final path should look like this:Documents\Klei\OxygenNotIncluded\mods\local\YourModName\ Step 4: Enable the Mod In-Game

Even though the files are in the right place, ONI won't load them automatically the first time. Launch Oxygen Not Included. From the main menu, click on Mods. oxygen not included how to install mods manually

Look for your mod in the list. Manual mods are usually easy to spot because they lack the Steam icon. Click the Enable button (it should turn green).

The game will notify you that it needs to restart to apply the changes. Click "Restart." Troubleshooting Common Issues

The Mod isn't showing up: Double-check your folder structure. If you have a folder inside another folder (e.g., local/ModName/ModName/mod_info.yaml), the game won't see it. The mod_info.yaml must be exactly one level deep inside the local folder.

The Game Crashes: Manual mods don't auto-update. If ONI recently had a "Quality of Life" update, your manual mod might be outdated. Check the source where you downloaded it for a newer version.

Version Mismatch: Ensure the mod is intended for the version of the game you are running (Vanilla vs. Spaced Out! DLC). Why Mod Manually?

Manual installation gives you total control. You can tweak the source code (if provided), prevent the game from auto-updating a mod that might break your save, and keep your game functional even when the Steam servers are down.

Now that your mods are set up, you can get back to the real challenge: figuring out where all that carbon dioxide is coming from.

3) Installing mods for ONI‑Modloader (third‑party modloader)

Use this only if you want features Harmony/C# mods require or if the mod author instructs ONI‑Modloader.

A. Install ONI‑Modloader

  1. Download the latest ONI‑Modloader release from its GitHub (e.g., Javisar/ONI‑Modloader).
  2. From the downloaded package copy ModLoader.dll (and accompanying Managed folder files) into the game Managed folder:
    • Windows: %PROGRAMFILES(X86)%\Steam\steamapps\common\OxygenNotIncluded\OxygenNotIncluded_Data\Managed\
    • macOS: OxygenNotIncluded.app/Contents/Resources/Data/Managed/
  3. Create a Mods folder in the game directory if not present:
    • Windows: %PROGRAMFILES(X86)%\Steam\steamapps\common\OxygenNotIncluded\Mods\
  4. Launch once and check Mod_Log.txt or the mod logs to confirm loader is active:
    • ...\OxygenNotIncluded\Mods\Mod_Log.txt or check game logs listed above.

B. Install a mod for ONI‑Modloader

  1. Download and extract mod; ensure correct folder structure.
  2. Copy the mod folder into the game Mods folder:
    • %PROGRAMFILES(X86)%\Steam\steamapps\common\OxygenNotIncluded\Mods[ModName]\
  3. Run the game and check logs:
    • Game logs (output_log.txt / Player.log) and Mods_Logs or Mod_Log.txt under the game folder.

Important: If you use ONI‑Modloader, do NOT also use the Steam builtin local mods folder for the same mod (conflicts possible). If ONI detects an external modloader it may bypass Steam Workshop; remove ModLoader.dll to use the Steam builtin loader.

For Windows (Epic Games / Microsoft Store Version)

  1. Open File Explorer.
  2. Paste the following path: C:\Users\YOUR_USERNAME\Documents\Klei\OxygenNotIncluded\mods
  3. Look for a folder named Local. If it doesn't exist, create it.
    • Path: ...\Klei\OxygenNotIncluded\mods\Local\

To manually install mods for Oxygen Not Included (ONI), you must place the mod files into a specific "local" folder within your game data directory. This process is the same whether you use the Steam or Epic Games Store version of the game. 1. Locate the Manual Mod Folder

Mods are stored in your User Documents, not the game's installation folder. Navigate to the path for your operating system: Windows: \Documents\Klei\OxygenNotIncluded\mods\local\

Mac OS: /Users/[YourUsername]/Library/Application Support/unity.Klei.Oxygen Not Included/mods/Local/

Linux: ~/.config/unity3d/Klei/Oxygen Not Included/mods/Local/

Note: If the local folder does not exist inside the mods folder, you must create it manually. 2. Download and Extract the Mod

Download your desired mod (usually as a .zip file) from a source like GitHub or Nexus Mods.

Extract the zip file. You should see a folder containing files like mod.yaml, mod_info.yaml, or various .dll files.

Place the extracted folder into the local directory discovered in Step 1. 3. Verify Folder Structure (Crucial)

A common mistake is "double-nesting" the folder, which prevents the game from seeing the mod. Your final path should look like this:.../mods/local/[ModName]/mod.yaml

If you see .../mods/local/[ModName]/[ModName]/mod.yaml, the mod will not load. 4. Enable the Mod In-Game Launch Oxygen Not Included. On the main menu, click the Mods button.

Look for your mod in the list. Local mods are often marked with a "local" or "dev" tag. Check the box to Enable it. Restart the game for the changes to take effect. Troubleshooting Download the latest ONI‑Modloader release from its GitHub

Installing mods manually in Oxygen Not Included (ONI) is a straightforward process that involves placing mod files into a specific "local" directory. This is useful for players using the Epic Games Store or those who prefer downloading mods from GitHub or third-party workshop downloaders. 1. Locate the "Local" Mod Folder

Mods for ONI are stored in your user documents rather than the game's installation directory. Navigate to the following path based on your operating system: Windows: \Documents\Klei\OxygenNotIncluded\mods\local\

macOS: /Users/[Username]/Library/Application Support/unity.Klei.Oxygen Not Included/mods/Local/

Linux: ~/.config/unity3d/Klei/Oxygen Not Included/mods/Local/

Note: If the local folder does not exist inside the mods directory, you must create it manually. 2. Download and Extract the Mod

From GitHub: Download the mod as a ZIP file (often via the "Clone or download" button).

From Steam Workshop (Non-Steam Users): Use a third-party tool like a Steam Workshop Downloader by pasting the mod's URL to fetch the files.

Extraction: Extract the contents of the ZIP file. Each mod should have its own subfolder inside the local folder. 3. Verify Folder Structure

Ensure your files are not "double-nested." The path should look like this:...\mods\local\[ModName]\mod_info.yaml A correctly installed mod folder typically contains: A .dll file (the main code). A mod_info.yaml file (metadata). A mod.yaml file. 4. Enable the Mod In-Game Launch Oxygen Not Included. Click on the Mods button in the main menu.

Find your manually added mod in the list. Local mods are often distinguished from Steam mods in this menu. Check the box to Enable it. Restart the game to apply the changes. Common Troubleshooting

Crashes: Ensure the mod is updated for your current game version (e.g., vanilla vs. Spaced Out! DLC).

Not Appearing: Double-check that the mod is inside a subfolder under local. The game will not recognize loose files placed directly in the local folder.
