How To Install MelonLoader For BTD6

There are two working installation methods. The recommended method is the automated installer because it automatically detects your BTD6 folder and prevents mistakes.

Method 1. Automated Installer

This is the easiest and most accurate way to install MelonLoader.

Steps

  1. Go to your official download page
    https://melonloader.pro/download-melonloader/
  2. Download the MelonLoader Installer
  3. Open the installer
  4. When asked to select your game, choose your Bloons TD 6 installation folder
    Typical Steam path

    Steam
    steamapps

  5. Click Install
  6. Once the installation is complete, launch BTD6 one time
    This allows MelonLoader to create all required folders such as Mods, Plugins, and UserData

If everything is correct, you will see a console window and a startup screen labeled MelonLoader when the game loads.

Method 2. Manual Installation

Only recommended for advanced users.

  1. Download the MelonLoader ZIP file from your official website
  2. Extract the files
  3. Move version.dll and the MelonLoader folder into the BTD6 directory
  4. Launch the game once to generate Mod folders

The manual method works, but mistakes are more common.

How To Use MelonLoader After Installation

After installing MelonLoader correctly, you can start using it to load mods.

Step 1. Locate The BTD6 Mods Folder

When BTD6 is launched for the first time with MelonLoader installed, the following folder is created automatically:

Mods

This folder is where all mod files must be placed.

If you do not see a Mods folder, MelonLoader did not install correctly. Reinstall using the official installer.

Step 2. Download Mods For BTD6

Mods for BTD6 usually come in the form of DLL files.
To use them, simply place each mod file inside the Mods folder.

For most mods you will also need:

BTD Mod Helper
A required mod library that adds support for custom UI, mod features, and mod compatibility.

Go to your official download page
https://melonloader.pro/download-melonloader/

Download it from the GitHub page
https://github.com/gurrenm3/BTD-Mod-Helper

Place BTD Mod Helper DLL inside the Mods folder.

Step 3. Launch BTD6 With Mods

Start Bloons TD 6 normally from Steam or Epic.
If MelonLoader is installed correctly, you will see:

  1. A black console window
  2. A MelonLoader startup screen
  3. A list of loaded mods in the console

The game will then continue to load with your mods active.

If the game launches without showing MelonLoader, something is wrong.
