About Lost Caves

🎉 WE GOT 1k+ DOWNLOADS!!! 🎉 I am eternally grateful to those who have downloaded the mod; without you, this wouldn't be possible. I'll work on other mods later and learn more about how to do it to bring you all new experiences with the game <3

❔About the mod:

This mod introduces a new portal fragment to Hytale, transporting players to a mysterious biome known as the Lost Caves. Hidden beneath the surface, this vast subterranean world combines stunning underwater landscapes with a constant, lurking danger.

Exploring the Lost Caves, players will encounter environmental hazards and discover breathtaking geological formations illuminated by the natural subterranean light. The biome is designed to be both beautiful and hostile, rewarding curiosity and challenging survival skills.

Deep within this hidden realm lies the forgotten civilization of the Slothians. Ruins, relics, and remnants of their once-great society are scattered throughout the Lost Caves.

The Lost Caves offer a rich exploration experience that expands the world of Hytale with a new atmosphere and adventure.

🧩To install:
