How to install Undertale

  1. This modpack runs on Fabric for Minecraft 1.21. The launcher you install it with sets that up for you.

  2. Download the .mrpack file from Modrinth.

  3. Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.

  4. Give the instance enough memory: most modpacks want 4 to 8 GB.

  5. To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
