An alien attacked here before the nuclear bomb attack and survived. Taking drugs made his body mutate sharply and become
As a result of a missile test in Antarctica, the test destroyed the ice layer of the Antarctic underground lake. In the first part, the alien queen who sank at the bottom of the lake woke up and the whole missile launch base was destroyed by the queen. Everyone died except one inferior soldier who ran away desperately, and aliens even took control of a huge ship. Because the ship was equipped with an automatic navigation system, the aliens left the South Pole, and the destination turned out to be that small town. The alien queen and the new alien king met for the fourth time.
Just when the earth was extremely critical, the disappearance of the lone wolf also attracted the attention of the Iron Planet. The lone wolf is an elite veteran in the iron blood. He will return to the iron blood planet after each successful mission, but this time he can't wait for the lone wolf to return. Elder Iron Blood, the elder brother of Lone Wolf, ordered his five most proud disciples to go to the last place where Lone Wolf appeared before he disappeared, that is, the town, to search for news of Lone Wolf. Five high-level young iron-blooded elites came to the earth and found that the town had spread all over the alien world. Five people got into a fight and withdrew. On the way back, they met the inferior soldiers who retreated from the South Pole. Meanwhile, they found a strange thing. A female human warrior actually used an iron weapon in the battle with aliens. Only elders can have iron spears. This person is the heroine who survived in the first movie.
As a result, Iron Blood and human beings unite again and try their best to destroy the existing alien legion. ........
