The story will go back to 18 years ago from 2001. In 1978, the Paleologos operation was defeated, and Poland fell the following year. Due to these two reasons, East Germany became the forefront of Europe's defense in 1983, and the fierce war began to spread. Due to the large-scale offensive of the BETA cluster, the defense line of the East German troops was in trouble. East Germany's top tactical mecha unit, the 666th Tactical Mecha Squadron Death Black Label, was ordered to eliminate the light-level BETA deployed in the rear with the combat power of only 8 riders to reverse the situation. Faced with a large number of BETA, the severe weather with continuous blizzards, and the heavy pressure imposed on them by the state power, they were forced to fight under harsh conditions. Where will their fate go?
