Features

Does what a mod loader needs to do and stays out of the way.

C# and Lua

Write mods in C# or Lua. Lua mods are plain .lua files, no compilation needed. Both use the same mod folder and config system.

Simple install

Extract the release to your game folder and put mods in Mods. Also works with the Moxi mod manager for one-click installs.

Manageable

Dependencies are resolved automatically. Disable any mod from RROML.config.json without deleting files.

Installation

  1. Download the latest release from the GitHub releases page.
  2. Extract the zip into your Railroads Online install folder. You should see a RROML folder there after.
  3. Create a Mods folder if it does not already exist.
  4. Put mod folders or .lua files inside Mods and launch the game.
Detailed steps for manual installation and for Moxi are in the documentation.
