NucleDoom
by Patbox
Players on a NucleDoom server can play the classic 1993 Doom inside Minecraft, with the game running through a Fabric mod for the 1.21.4 release.
What it does
The mod turns a Minecraft session into a playable version of Doom from 1993. Movement uses the usual keys: WASD to walk, Shift to run, the mouse to look around. The left button fires a weapon, the right button uses things, and keys 1 to 7 switch between weapons. Sounds are supported and the author describes them as accurate to the original.
NucleDoom is meant for a server rather than a single-player world, and the author points to a main server in Europe where it can be tried. Because it is server-side only, players join without installing anything and only the server runs the mod. It needs Fabric API, Plasmid and Polymer, and it is published for Fabric alone, with a single file for 1.21.4.
The custom license means the mod is not open source. Its source code and issue tracker are public, and the first file went up on 2025-04-01, with the latest one dated 2025-04-03.

How it compares
Play Doom on screen runs on Fabric and Forge for 1.20.1 – 1.21.1 as a client and server mod, so both sides need it, and it is released under All rights reserved licensing. Doom the Dark Ages: BFC is a Fabric mod for 1.21.11 that also needs both sides, under All rights reserved licensing. Creamy Mc is a Fabric client-side mod for 1.21.11, so only the client needs it, unlike NucleDoom which runs on the server alone.
