The Undertale mod for Minecraft can be installed using any mod loader that has Fabric installed. For this guide, we have used Modrinth and its mod loader with Fabric.
Here's how you can download and install the Minecraft Undertale mod:
- Head over to Modrinth and download the official launcher.
- Once downloaded and logged in with your Mojang credentials, search for the Undertale mod by Clouser. Alternatively, you can click this link to get to the official Modrinth listing.
- If you wish to manually install the Undertale mod, just click on the green Download button and select the game version and platform. Once done, download and place the ZIP file in the mods folder of your desired Minecraft instance. However, if you do not have an instance with Fabric installed or are new to installing mods in Minecraft, you should use the Modrinth loader.
- For installation using the loader, click on the green Download button, which will prompt you to install with the Modrinth app. This will open up a deep link to the downloaded Modrinth app.
- Once the app loads, you will be prompted to create a new instance or choose an existing Minecraft instance. While you can choose an existing instance, it is highly recommended to install the Undertale mod on a fresh instance of the game. This essentially avoids conflicts with existing mods, shaders, or data packs and eliminates the risk of world corruption.
- Create a new instance and name it. After creating the instance, you will be redirected to the page. Wait for the mod and all its assets to get installed.
- Once the files are downloaded and it is ready, click the green Play button on the left to launch Minecraft with the Undertale mod successfully installed.
