Ore to Core

Mine. Smelt. Automate. Dig to the core of the Earth.

A side-view mining and smelting automation game in pixel art. Molten metal flows from your furnaces into molds, and beneath your factory, ancient dungeons wait with monsters and loot.

For fans of Factorio, Terraria and Path of Exile.

The player's base on the surface: furnaces, a campfire and a shaft with a ladder going down, mountains behind.

The loop

Dig down. Build up. Descend.

One loop that keeps pulling you deeper: every trip down makes the factory stronger, and a stronger factory takes you further down.

Dig by hand

Every grain you mine lands in your pack. Digging by hand is slow on purpose: soon a drill will do it for you.

Smelt and automate

Heat your furnaces, pour molten copper and bronze into molds, and link drills, belts and furnaces into a production line.

Descend for loot

Forge a rune, open the gate in the ruins and drop through a glowing fissure into the dungeon. Come back with gear and dig on.

Automation

A factory in cross-section

You see the whole mine from the side: shafts, ore veins, tunnels and the furnaces above them. Every metal melts at its own temperature, so heat and fuel matter.

Molten metal you can see: pour it into molds and cast ingots.
Ores are mined, not smashed: every vein holds a real amount of ore for your drills.
Drills, belts and furnaces keep working across the whole world, even off screen.
Nothing is wasted: every grain can be recovered and by-products have a use.
Always a next goal: the tracker tells you what to do now.

Action RPG

Dungeons beneath your factory

Ruins on the surface hide gates to the underworld. Forge a rune, step through and fight top-down in the ancestors' ruins, lit by torches and lava.

Monsters of rising rarity, and bosses that change tactics as they weaken.
Trial chambers that seal behind you, and treasuries opened by lit seals.
Traps you can read: spike plates click, fire vents glow before they erupt.
Gear drops to the floor: hover for stats, click to pick it up. Bosses can drop uniques.
Deeper gates bring corruption: tougher monsters, richer loot.
Your factory needs what only the dungeons hold, and it keeps running while you are below. No penalties for failure, no timers.
