"This is the ideal life we envisioned for all citizens of earth, however, the manifested alien species with its corrosion spreading at rapid speed is making this mission almost impossible to achieved. But with our efforts in accepting and training cadets like you to be of the military ranks and gain abilities just like the Suits, we believe this mission will not be far-fetched anymore."
The trainees smiled and nodded in understanding. It was already registered in their mind what they have to do.
For humanity, they have to train.
To fight against the manifested alien species, they have to gain the ability to fight against these monsters.
Suits were created as a temporary measure while the human fortresses were researching the correct way to gain immunity against corrosion. However, the research is not progressing as suspected. Even the experiment subjects, like the Suits, were barely helping out either.
