by Kapp

Undertale Additons brings items, weapons and armor from the Undertale game into Minecraft, and it is built with MCreator for Forge and NeoForge.

ForgeNeoForgeClient and serverAll rights reserved1.20.1 – 1.21.1

What it does

Iconic objects from the Undertale game are added as items, weapons and armor, with 3D models that give them a distinct look in the world. Some items carry slight changes from their original form, and a few extras are included beyond the core set. The mod was made with MCreator and aims to bring the game's recognizable pieces into survival and creative play.

Undertale Additons needs Curios API on either loader. Servers that run it need every player to install it too. Files are published for Forge 1.20.1 and NeoForge 1.21.1, and the mod is licensed under All rights reserved, so it is not open source. Forge builds were updated to version 1.1.2 on 2025-11-06, and NeoForge builds to 2.02 on 2026-07-19.

Key features

  1. Undertale items

    Items drawn from the Undertale game are added to the game, each with its own recognizable form.

  2. Weapons and armor

    Iconic weapons and armor pieces from the game are included as equippable gear.

  3. Slightly altered items

    Several items are adjusted slightly from their original design so they fit Minecraft's item system.

  4. 3D models

    Items come with 3D models, so they appear as full objects in the world and in the hand.
