Discord •

IMPORTANT: version 2.0.0s is in active development and the FIRST ALPHA has been released on Modrinth. If you think the dimension is currently lacking in content, or just want to give feedback on the next update, please join our Discord server: https://discord.com/invite/GDNRd5yvxa. The new update branch (Spruce), planned initially for Fabric 1.20.1 and 1.21.1, will add actual progression to the dimension and expand the amount of biomes and entities.

About

Deeper and Darker is a mod that aims to enhance the Deep Dark in Minecraft. It adds many new features related to the Deep Dark and a new dimension called the Otherside.

Content

Deeper and Darker adds an entire new dimension — the Otherside — with much content to explore. Here's a list with some of the features!

  • Biomes: explore the deeplands, echoing forest, overcast columns, and blooming caverns.
  • Structure: find an ancient temple, the home of the warden! Just be cautious when breaking the ancient vases to avoid awakening an ancient lurker.
  • Blocks: over a hundred new blocks to build, including gloomslate, sculk stone, and a new wood type!
  • Items: a brand-new warden set of armor and tools, an upgrade to elytra and the awesome sculk transmitter!
  • Mobs: 8 new mobs, including a miniboss!

To enter the Otherside, kill the warden and use its heart. Play the mod to find more content and explore hidden mysteries!
