FurinaLC is a server reimplementation for Limbus Company, named after the second-best girl from Genshin Impact.
As stated in the license, there is no liability. This project obviously breaks Limbus Company's terms of service, so if anything happens, just remember that you have been warned.
Be sure to check out the Frequently Asked Questions.
This guide is Windows-oriented. If you're using Linux, you probably already know how to set things up. (I use arch btw.)
Most important requirement: a brain.
-
uv (v0.4.22+)
Install uv by running the following PowerShell command:powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"Note: You might need to set up an environment variable for
uv. By default, you can finduv.exeinC:\Users\<username>\.local\bin. If you're unsure how to do that, ask ChatGPT. -
MongoDB (v8.0.3+)
Download and install from MongoDB's official website. -
Git
Install Git from Git's official website. This is required for cloning the repository. -
FurinaLC.Tool.Proxy
Download from this link. Alternatively, you can use any HTTP proxy tool that allows modifying requests.
If you prefer a tutorial video, you can watch this video, made by Ishmael. It is kinda outdated, but you can simply skip the Python install step. And for the Fiddler install & setup, you should follow the Proxy guide in this README instead, as it's much easier to use.
-
Install MongoDB:
Follow the installation guide for your operating system from the MongoDB installation page. -
Configure MongoDB Connection:
Once installed, connect to MongoDB using the following connection string:mongodb://127.0.0.1:27017
That's all for MongoDB setup!
This proxy will redirect API requests to your local server. Follow these steps to configure it:
-
Download FurinaLC.Tool.Proxy:
Download it here and unzip it. -
Run FurinaLC.Tool.Proxy.exe:
When prompted to install a certificate, allow it. We need it to decrypt HTTPS traffic. After this, the tool should automatically set itself as the system proxy (and revert this when you close it).
Note:
-
If you're unable to browse the internet after using and closing this proxy, it might be due to Guardian failing to revert the proxy settings.
-
If that happens, simply disable the proxy settings manually (Open windows search, then type "Proxy", the settings menu option should show up). Alternatively, run the proxy app again and close it by clicking the big red X.
Now that MongoDB and FurinaLC.Tool.Proxy are configured, follow these steps to set up FurinaLC:
-
Clone the Repository:
Clone the repository to your machine using Git:git clone --recursive https://github.com/LEAGUE-OF-NINE/FurinaLC.git
The
--recursiveflag is required for submodules. Be sure to sync the submodules every time the game updates if you want the latest identities and other content. -
Navigate to the Project Directory:
cd FurinaLC -
Start the Server:
Run the following command to start the server:uv run -m server
Once the server is running, you can launch Limbus Company. Ensure that the proxy is running and properly redirecting the API requests to your local server.
