The time has come when the Earth has to be protected not on the planet itself, but outside of it. Our planet, even though its resources are running out, is still of interest to certain races from space. They take over the planet, pump out resources and leave it completely devastated and uninhabitable. No one wants a similar fate for humanity, so your ship is sent to meet the squadron of alien aggressors to stop them and give a fitting rebuff. The battle will be hot, the enemy is strong and treacherous. But your exterminate is equipped with the best weapons that shoot automatically.
