With only a shoddy pickaxe to start, you must hire and promote employees, upgrade equipment and dig deep below the earth to fill your coal quota each day. Or else.
The underground world magically refreshes each day, so you must race to mine as much of it and as deeply as you can before nightfall. Using some very exciting and hyper-realistic methods for doing so. Your world might deteriorate as you grow, however.
You heard that right. Hire and promote employees into specialised roles in your organisation, each type having exciting and game-changing bonuses and equipment. Grow your organisation into hundreds, thousands, millions and even billions of miners willing to go out and bring back coal for the cause.
Many different maps, professions and tools means endless ways of growing your operation. Do you have what it takes to grow the greatest coal mining corporation of all time?
