About this Mod

Welcome to the Echo Dimension!

Secret of the Ancient City: Echo Dimension mod expands Minecraft with a new dark dimension, powerful echo-themed tools and armor, ancient structures, functional blocks, dangerous exploration, and a major boss fight against the Echo Warden Monarch. It is designed to feel connected to vanilla Minecraft while adding a deeper endgame progression path.

Players begin by exploring the Deep Dark and Ancient Cities, discovering echo materials, crafting special items, activating an ancient portal, and entering the mysterious Echo Dimension. Inside this dimension, they will find strange terrain, rare resources, hidden structures, dangerous encounters, and the path toward the final boss.

Echo Warden Monarch
