Many decades after the start of the space war, our Earth has become an arid planet. People began to live in underground complexes and under armored domes, and only lone gun bases served as the last line of Earth's defense. After the last of the Earthlings ' fleets was destroyed, humanity has one last hope left. The command decided to raise an old alien battleship in the air, and was immediately attacked by foreign invaders.
