Plays inside your own copy of Minecraft: Java Edition, on your device, not in a browser tab. Opens modrinth.com in a new tab.
How to play
Have your own copy of Minecraft: Java Edition installed: the mashup plays inside it.
Download it from its release page on Modrinth.
Install it as its page says. What it asks for is just below, in the list's words.
Start the game the way its page says: some mashups come with a launcher of their own.
What it asks for
Fabric server with Plasmid, Polymer and Fabric API; client mods are not needed (Modrinth: client unsupported, server required). Ships Doom shareware and Freedoom WADs. The repo's master branch has an unreleased 'Update to 26.3' commit (2026-09-29).
