An industrial empire is waiting beneath the surface—and it starts with a pickaxe. Mine ore, haul it to the base, and choose: sell your stock now or turn it into materials and valuable products. Discover new deposits, launch mine carts, build workshops and factories, research technologies, and connect everything into one living production network.
Buying upgrades is only the beginning. Find bottlenecks, choose profitable recipes, prepare for rare contracts, and decide where your limited materials matter most. When you are ready for the next leap, reorganize the company, keep permanent advantages, and begin a faster, deeper cycle.
Your complex keeps working while you are away. Return to accumulated resources, rebuild your production plan, and watch one small mine become a vast underground industry.
How to play
Begin in the copper mine: tap “Mine manually,” fill the bunker, haul the ore to your base, and sell your first stock. Spend the hexes you earn on research and equipment.
Keep the whole chain moving: drills must produce, mine carts must haul, and workshops and factories need a steady supply of materials. If a facility stops, tap its status to discover and fix the cause. Choose recipes, save materials for research and major projects, or deliver them through profitable contracts.
Unlock new mines, automate the complex, and reorganize the company to gain permanent bonuses for future cycles. Progress is saved automatically, and part of your production continues while you are away.
