This is a BepInEx pack for Undermine, preconfigured and ready to use on Windows!
BepInEx is a general purpose modding framework for Unity modding. BepInEx includes tools and libraries to
- load custom code (plugins) into the game on launch;
- patch in-game methods, classes and even entire assemblies without touching original game files;
- configure plugins and log game to desired outputs like console or file;
- manage plugin dependencies.
💡 Tip
The game folder is the folder containing the game's executable (e.g. UnderMine.exe).
Steam users can find the game by right-clicking the game in their Steam library and selecting Manage -> Browse local files.
To install, follow these instructions:
1. Download the file from the Files Tab
2. Extract the contents of the downloaded archive into the game folder.
ℹ️ That just means open the .zip file and drag the files and folders into the game folder!
3. Run the game.
💬 Important
With just this pack installed, you will not see any changes in-game!
Check the LogOuput.log file in the BepInEx folder to determine whether BepInEx has loaded.
