Install Secret Mission: Christmas in GDLauncher

  2. Pick the NeoForge loader and a Minecraft version that Secret Mission: Christmas supports (1.21.1 are common choices).
  3. Open the new instance, go to the Addons tab, and click Add Addons.
  4. Paste the Quick Install ID #secret-mission-christmas, find Secret Mission: Christmas in the results, and hit Download. GDLauncher pulls dependencies automatically.
  5. Hit Play. That's it.

Before you install

Make sure your Minecraft version matches what Secret Mission: Christmas supports. As of the latest release, 1.21.1 are supported. Secret Mission: Christmas only runs on NeoForge; mods built for other loaders won't work. GDLauncher checks compatibility for you and won't install something incompatible with the instance you've chosen.
