YUNG's Better Dungeons

YUNG's Better Dungeons is a world-generation mod created by YUNG. Replaces vanilla dungeons with hand-crafted designs featuring multiple rooms, varied layouts, and improved loot. As a world gen mod it concentrates on terrain, biomes, and the shape of the world itself, and it has been downloaded around 25 million times, which puts it among the options players reach for in this space.

YUNG's Better Dungeons is built for players who want vanilla dungeons reimagined as sprawling, rewarding builds. Part of YUNG's structure suite, it replaces plain dungeons with multi-room complexes full of traps, mobs, and tiered loot. It is approachable enough to drop into a world and use right away, with little setup required.

The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

YUNG's Better Dungeons works particularly well alongside YUNG's API. It depends on YUNG's API, so those must be present and on the same loader and version. Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.

YUNG's Better Dungeons has a modest footprint for what it adds and is widely used in modpacks without notable performance concerns.

If you are comparing options, similar mods include When Dungeons Arise and Better Dungeons. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
