Many decades after the space war, our world has become a dry planet. People began to live in underground complexes and under armoured cupolas and only the lonely gun base served as the last line of earth defense. After the last of the fleets of the Terrans were destroyed, humanity has one last hope. Command decided to raise the old alien battleship in the air, and was immediately attacked by foreign invaders.

You take the command of the special anti-ship battery. Use the keys a and d or arrows to control your weapon. Press spacebar for shot. Your gun will be continuously improved for a successful defense you need to destroy all enemy ships and to do it as quickly as possible. The crew of the battleship will help you to fend off the landing capsules.
