This is a mining smelting idle game. There is also turn-based combat.
Minerals collected include coal mines, oil, natural gas, and uranium mines.
The resources of each mineral are limited and need to be explored. The mineral source is occupied by the enemy forces, and it is necessary to make weapons to eliminate the hostile forces.
To make weapons, you need smelted raw materials, and raw materials to make weapons form a closed loop of the game.
