In the last part of this amazing game, we were able to fight off all the attacks of the giants - the aliens and protect the city. But the peaceful life did not last long, because, as it turned out, there were several such faults. New fault opened when we closed last. New giant waves threaten the civilian population, but on the other side of the planet. You go there and will protect the people, setting defensive guns and improve them.
