What Is Modding in Video Games?
Modding is the process of modifying or changing a video game to add new content, improve features, or customize gameplay. The word “modding” comes from the term “modification.”

Some common examples of mods include:

- Better graphics
- New character skins
- Additional weapons or tools
- Custom maps
- New missions and storylines

Many gamers enjoy modding because it gives them more control over how a game looks and feels. Instead of playing the default version forever, players can personalize the experience according to their preferences.

Following these precautions helps prevent crashes and compatibility issues.
Requirements Before Installing Mods in Subnautica
Before you start modding Subnautica, make sure you have the following:
A Legitimate Copy of Subnautica
Most mods work best with official versions of the game purchased through:
- Steam
- Epic Games
- Other supported platforms
Enough Storage Space
Some large mods may require additional storage space, especially graphical enhancement packs.
File Extraction Software
You may need software like:
- WinRAR
- 7-Zip
These tools help extract compressed mod files.
Basic Understanding of Game Folders
You do not need advanced technical skills, but understanding how to navigate folders on your PC will make the process easier.
Step-by-Step Guide to Mod Subnautica
If you want to install mods in Subnautica successfully, follow these exact steps carefully.
Step 1: Locate the Subnautica Installation Folder
The first thing you need to do is find the main installation directory of the game.
If you are using Steam:
- Open Steam
- Go to your game library
- Right-click on Subnautica
- Select “Manage”
- Click “Browse Local Files”
This will open the main Subnautica game folder on your computer.
This folder is extremely important because all modding files will be placed here.
Step 2: Download Tobey’s BepInEx Pack
To run modern Subnautica mods, you need an essential modding framework called BepInEx.
You can download:
- Tobey’s BepInEx Pack from Nexus Mods
BepInEx acts as the core engine that allows custom modifications to work inside the game.
Without BepInEx, most modern Subnautica mods will not function correctly.
Step 3: Extract the BepInEx Files
After downloading the BepInEx Pack:
- Open the downloaded archive
- Extract all files
- Copy the contents directly into your main Subnautica installation folder
Make sure the files are pasted exactly where the game launcher executable is located.
This step is very important because incorrect folder placement can stop mods from loading properly.
Step 4: Launch Subnautica Once
Now launch Subnautica from Steam.
Allow the game to:
- Reach the main menu
- Fully initialize the new modding framework
After reaching the main menu:
- Close the game completely
This first launch is necessary because BepInEx automatically creates important folders required for future mods.
Step 5: Download Nautilus
The next important tool is Nautilus.
Nautilus is a support library that helps different Subnautica mods communicate with the game correctly.
It greatly improves:
- Mod compatibility
- Stability
- Functionality
Many popular Subnautica mods depend on Nautilus to work properly.
Step 6: Install Nautilus Correctly
Once downloaded:
- Extract the Nautilus files
- Open the newly created BepInEx folder
- Locate the “plugins” directory
- Place the Nautilus folder inside the plugins folder
The correct folder structure is extremely important.
Incorrect placement may cause:
- Game crashes
- Missing mods
- Startup errors
Step 7: Browse for Subnautica Mods
Now comes the fun part — choosing your favorite mods.
Visit trusted modding platforms and browse available gameplay enhancements.
Popular categories include:
- Better graphics mods
- Quality-of-life improvements
- Survival overhaul mods
- Custom maps
- Vehicle upgrades
- Building expansions
Always check:
- User ratings
- Compatibility notes
- Latest update dates
- Installation instructions
This helps avoid outdated or broken mods.
Step 8: Download and Extract Mods
After selecting your mods:
- Download the mod files
- Extract the archive
- Copy the extracted folders into the same plugins directory used for Nautilus
The plugins folder acts as the main location where Subnautica loads custom modifications.
Each installed mod will automatically activate when the game launches.
Step 9: Launch the Game With Mods Enabled
Once everything is installed:
- Start Subnautica again
- Wait for the game to load
- Check if the mods are working properly
If installed correctly, your new features should appear automatically inside the game.
Congratulations — you have successfully modded Subnautica!
