Our planet aliens planned attack. They gathered a huge army and heading towards Earth. Our military has sent all who could overcome them, no one came back alive and then you have agreed to become a volunteer. Military was ridiculous, they do not believe that you can survive, but there is no choice. You are in the space in front of you and a huge army of enemies. Fight for life on our planet, do not let them get close to us! Life of the planet depends on you.
