Installing Lethal Company Mods with MO2

This guide will cover how to setup MO2 for Lethal Company Modding, including the Bigger Lobbies Mod.

Mod Organizer 2

The main benefit of Mod Organizer 2 (MO2) is the ease of managing mods (naturally), and being able to maintain a vanilla copy of Lethal Company on your machine. MO2 uses a virtual folder system, so that the original directory of Lethal Company will be untouched by the installation.

The program is found on the Skyrim Special Edition Nexus site, though its a universal tool for modding games.

1. Download and install Mod Organizer 2 from Nexus (https://www.nexusmods.com/skyrimspecialedition/mods/6194)
   
2. Follow the installation instructions on that link for assistance
   
3. I recommend installing MO2 in an easy to access folder, such as C:\Users\<username>\Modding\MO2\
   
4. This guide will assume you used the above installation path here on out.

MO2 Extensions

This section covers extensions to MO2 that make modding possible and leaving a clean vanilla build of Lethal Company.

Firstly, to allow an instance of Lethal Company to be made in MO2:

1. Download the extension from Nexus: https://www.nexusmods.com/site/mods/701
   
2. Open the ZIP file using 7-zip (or equivalent)
   
3. Right click on the 'plugins' folder and select to 'Extract...'
   
4. In the selection menu, select the MO2 installation folder, in this case C:\Users\<username>\Modding\MO2\

Now to allow the Unity Modding Framework BepInEx to be installed without impacting the Lethal Company directory, we'll need Root Builder:

1. Download Root Builder from Nexus: https://www.nexusmods.com/skyrimspecialedition/mods/31720
   
2. Open the ZIP file using 7-zip (or equivalent)
   
3. Right click on the 'plugins' folder and select to 'Extract...'
   
4. In the selection menu, select the MO2 installation folder, in this case C:\Users\<username>\Modding\MO2\plugins\

Setting Up Instance

Now we can setup the Lethal Company Instance:

1. Open MO2
   
2. Select Create New Instance
   
3. Choose Global Instance
   
4. Select Lethal Company from the list
   
5. Name it whatever you want, but for simplicity keep the default name 'Lethal Company'
   
6. Leave the installation option default as we won't be touching the files ourselves, unless you want to change it for whatever reason
   
7. Select Finish and launch the new instance.

It should look like this if you setup everything correctly:

Installing Mods

First, make to sure to build your Root for installing BepInEx. Do this by opening RootBuilder:
Once you've opened this, keep everything default and click Build:
This will now allow BepInEx to function.

Now to actually install the mods. First, BepInEx:

1. Download the 64bit version of BepInEx from GitHub: https://github.com/BepInEx/BepInEx/releases
   
2. Select to install a mod. The button is highlighted in this screenshot:
   
3. Choose the BepInEx ZIP file
   
4. Important: Click Manual when asked to name the mod
   
5. MO2 will now brief you on wrongly formatted mods with an on-screen tutorial, ignore and skip through these
   
6. When you have control, format the mod as such, by right clicking on <lethal company> and selecting to create a new directory 'Root', and then drag all of the contents under 'Root':
   
7. After installing don't forget to enable the mod on the left-hand side:
   
8. You've installed your first mod! Now follow the steps below:

We can now install the Lethal Company API:

1. Download the API from Thunderstore, I recommend a Manual download unless you know what you are doing: https://thunderstore.io/c/lethal-company/p/2018/LC_API/
   
2. The same way as BepInEx, select to install the API, and ensure the filetree of the mod (under Manual again) looks as such, with BepInEx being the top level directory rather than Root:
   
3. After installing don't forget to enable the mod on the left-hand side

---

Finally we can install Bigger Lobbies:

1. Download the API from Thunderstore, I recommend a Manual download unless you know what you are doing: https://thunderstore.io/c/lethal-company/p/2018/LC_API/
   
2. The same way as before, select to install Bigger Lobbies, however this time you don't need to select Manual, just install in with the default file path
   
3. After installing don't forget to enable the mod on the left-hand side

Conclusion

If you want to play Lethal Company with no mods, launch regularly through Steam. If you want to play with the new mods, launch it through MO2 on the right-hand side:
To confirm if the mods installed correctly, check the bottom left corner of the main menu. It should indicate that its modded.

So, functionality with the latest LC API is...bugged.

I can appreciate that, though I highly recommend using R2modman for Thunderstore instead, as its not installed with the third-party app Overwolf. It also doesn't have ads running in the mod manager

That is so much effort compared to just using Thunderstore lmao
