Overview
The Undergarden is a adventure mod created by Quek. A dark underground dimension mod filled with bioluminescent flora, unique creatures, and progression-gated bosses. As a adventure mod it concentrates on exploration, structures, and new things to fight, and it has been downloaded around 8 million times, which puts it among the options players reach for in this space.
The Undergarden is built for players who want a fresh underground dimension to explore and exploit. It adds a fog-laden underground realm with its own biomes, mobs, and materials, reached through a portal lit differently from the Nether. It rewards a bit of learning, so expect to spend some time understanding its systems before they click.
The mod is available for Forge and NeoForge, so it fits a range of modpacks and launchers. It currently targets Minecraft 1.20.1. 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.
