MelonLoader is a free-to-use utility that allows you to load any mod for any app developed using the Unity Engine. It eliminates the need to use different mod loaders, making it a convenient tool for custom players as well as developers of custom content.

Aside from the game-specific mods it can store, load, and modify, it also has its own set of modifications that change the tool’s performance, appearance, and capabilities. To give you an idea of its scale, imagine a single app for managing all your mods for games like Cuphead, Subnautica, Escape from Tarkov, and Cities: Skylines.

Create and load any mod for Unity

One factor that allows MelonLoader to act as a universal mod loader for Unity games is its support for IL2CPP and Mono, two of the most commonly used scripting backend frameworks for developing apps in the cross-platform Unity Engine environment. Additionally, it has found support from local modding communities of certain games, which means additional support and resources from modders and fellow users for certain games.

As a tool, it also has a very small file size, so you won’t have to worry about storage. However, take note that it requires a bit of technical knowledge to use properly. It can take a couple of tries to get it running properly, but it gets easier with use. With that said, the app has other capabilities aside from loading mods for games.

It has a built-in debugger, for example, that lets you modify content in-app. It also offers screen customization commands, which allow you to modify the user interface or load a theme. It is also optimized to the point where you can use it for games inside other launchers like Steam or Epic Games, although generally, you should limit it to single-player games only to avoid bans.

How to use MelonLoader

To manually use MelonLoader, ensure the game is closed and all requirements are met. For installation, download and extract the MelonLoader folder along with the version.dll and dobby.dll files into your game's directory. To uninstall, simply delete version.dll and the MelonLoader folder. For a full cleanup, optionally remove the Plugins, Mods, and UserData folders. Re-installing requires completing a full uninstallation before repeating the setup.

Compact modding tool

If you’re a modder or a player who enjoys custom add-on content, MelonLoader will definitely come in handy. Its integration with the Unity Engine, through the IL2CPP and Mono frameworks, means that it can be used for a lot of modern games. Furthermore, it comes in a small file size and doesn’t limit itself to loading and running mods — letting you debug content and even customize the feel of this app.
