Doomlike Dungeons

Doomlike Dungeons adds huge multi-room dungeons modelled on levels from retro 2.5D shooters like Doom, inspired by the Oblige level generator. It uses no prefabricated rooms: all room geometry is generated at run time, so an interesting room is likely unique to your world, and a dungeon can span up to 13 chunks.

Data packs let you change themes, which mobs spawn (including modded ones) and NBT loot. Available for Forge and NeoForge on Minecraft 1.12.2 - 1.21.1. Clearing these dungeons is better with a team, so install it on your Minecraft server from the panel in one click.
