Description

Short

A dwarven mining incremental game. Dig through 20+ depths, build 13 specialized rooms, automate your underground empire, and prestige for permanent power. Trade with nations, tame beasts, craft runestones, and ascend to unlock even deeper progression. Every sound and visual is procedurally generated.

Long

Mithril & Mud is a dwarven mining incremental game where every swing of the pickaxe brings you closer to the riches buried below. Start with nothing but stone and ambition — end with a sprawling underground empire fueled by mithril, shadowsteel, and ancient rune magic.

Descend through 20 increasingly dangerous depths, each unlocking new rooms, resources, and challenges. Construct and upgrade 13 specialized rooms — from Smelters and Lumber Mills to Runic Workshops and the Dark Forge. Unlock automation systems that keep your empire running while you're away. Prestige grants Ancestral Knowledge and Blessings that carry forward. Ascension opens an entirely new layer of progression.
