Depth Shaft Idle

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.
