About this project
What does Alex's Caves Up add?
Alex’s Caves Up introduces six unique cave biomes to the Overworld. These underground biomes are extremely rare to discover, and each offers its own distinctive environment filled with exclusive blocks, items, creatures, and gameplay mechanics. The mod features the Magnetic Caves, Primordial Caves, Toxic Caves, Abyssal Chasm, Forlorn Hollows, and Candy Cavity, each providing a different underground adventure.
This port brings the original content and mechanics to NeoForge, along with several bug fixes and additional mod compatibility. Although the port is considered complete, it may still contain some bugs. Newer Minecraft versions are planned.
