Description

Short

Dig a cozy dwarven hold into the deep. Hire miners, build 13 rooms, earn helpers that run the mine for you, then start a New Dig with an omen and dig deeper. Past depth 20 the tunnels never end: four biomes, four Wardens, and plenty of shiny things to get mud on.

Long

A dwarven mining incremental. Build your hold and dig deeper every run.

Mudheim is an incremental mining game. You start with one ore vein and a pickaxe. Click the vein, hire Dwarf Miners, and build rooms around the cave. Soon the carts are rolling, the tavern is full, and your dwarves are asking where the next tunnel goes.

The Foreman, the Overseer, the Quartermaster, the Smeltmaster and more sign on as you progress. Each one takes a chore off your hands, and you can switch them on or off, save profiles, or pause them all.

Every descent costs more and pays more. Cave-ins block the way, and trolls and a dragon come raiding. Your Runic Warriors handle them.

Start a New Dig to earn Ancestral Knowledge and spend it on permanent blessings. Before each dig the elders read the stones.

Act one ends at depth 20 with a crown to forge, and the story reaches its ending at depth 40. The tunnels keep going: the Emberdeep, the Drowned Halls, the Crystal Choir and the Hollow Dark, each with its own rule twist and its own Warden to beat.

Mudheim is made by CampbellSoft Studios, a small studio.
