WARNING

You will probably get banned for using FurinaLC.

It's recommended that you use Lethe instead (especially with Zwei) as it bypasses and blocks any sort of detection for private servers that Project Moon added.

However, if you're already banned, or do not care at all, enjoy.

FurinaLC

PROJECT STATUS

This project is not currently under active development and is unlikely to resume in the foreseeable future. However, updates will still be provided to address changes in Limbus Company packet encryption if they occur, and enhancement pull requests are welcomed.

---

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.

Getting Started

This guide is Windows-oriented. If you're using Linux, you probably already know how to set things up. (I use arch btw.)

Requirements

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 find uv.exe in C:\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.

Step-by-Step Setup

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 It is kinda outdated, but you can simply skip the Python install step.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.

1. Setting Up MongoDB

• 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!

2. Setting Up FurinaLC.Tool.Proxy

This proxy will redirect API requests to your local server. Follow these steps to configure it:

1. Download FurinaLC.Tool.Proxy:
   Download it here and unzip it.

2. 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).

3. Setting Up FurinaLC

Now that MongoDB and FurinaLC.Tool.Proxy are configured, follow these steps to set up FurinaLC:

1. Clone the Repository:
   Clone the repository to your machine using Git:

   git clone --recursive https://github.com/LEAGUE-OF-NINE/FurinaLC.git

   The --recursive flag is required for submodules. Be sure to sync the submodules every time the game updates if you want the latest identities and other content.

2. Navigate to the Project Directory:

   cd FurinaLC

3. Start the Server:
   Run the following command to start the server:

   uv run -m server

4. Play the Game

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.
