Go to outer space to the front line. Here, hundreds of enemy fighters want to break through the defense line. And you have to keep it. To do this, you have at your disposal the best warships of the fleet. And all sorts of bonuses, improvements and useful devices. Use everything wisely to hold the defense and prevent the enemy from breaking through. Of course, the enemy will not rest on the sidelines. The size of the army will increase, and the power will increase. But you will certainly cope with the mission of extermination if you make every effort. Good luck in the game!
