Upgrade Underground – Caves Overhaul

Upgrade Underground is a lightweight Vanilla+ cave-overhaul mod designed to add more subterranian content. It introduces an new biome, essential underground survival items, deeper progression mechanics, and unique structures to discover while mining.

 

 

 

Lichen Garden

Lichen Vegetation: Lichen Sprouts, Tall Lichen Sprouts, and Lichen Mushrooms.

Lichen Wood: Chop down Lichen Trees to gather exclusive Lichen Wood and Lichen Leaves for building.

Glow Lichen Cap: A handy early-game helmet made from a Leather Helmet, a Lichen Mushroom, and 2 Lichen Sprouts. It provides 1 Armor and acts as a portable light source (Level 6 light in a 3x3x3 area).

 

Lichen Mushrooms: A new cave food source. Cook them to save yourself from eating rotten flesh! They smelt faster, though they provide low saturation.
