What You'll Build

From a simple pickaxe
to a sprawling factory.

Three core pillars drive the chaos underground. Every belt you place, every machine you buy, every cavern you explore changes the shape of your operation.

// 01 — BUILD

Build a Sprawling Factory

Start with a pickaxe and a few coins. Save up for your first autominer, and from there the automation begins. Wind conveyors through twisting mineshafts, connect machines, and let physics handle the rest.

From swinging a pickaxe to running an interconnected industrial network — the only limit is the rock around you.

// 02 — EXPLORE

Venture Into the Unknown

The hollowed shell of a forgotten cave system stretches in every direction. Discover secrets, unearth hidden resources, and rebuild among the ruins of abandoned mining operations.

Every cavern holds new opportunities — and new puzzles for the ambitious mogul.

Manage the Chaos

As your factory grows, the madness grows with it. Conveyors overflow. Parts scatter. Physics mishaps keep you on your toes.

Tweak your designs. Optimise machine placement. Find creative solutions to keep the gears turning — or watch the whole thing fall apart in the most spectacular ways.
