The explosion was a long time ago. No one remembers what it was that exploded. Was it just a bomb, or a nuclear power plant? But the explosion was massive. All who remained on the surface have long died or mutated. Only those who took cover in basements and other shelters survived. I am part of the generation of people who were born underground. Checking the air on the surface, it turned out that it had cleared. But now we must clear the abandoned cities of the monsters so we can live under the sun again.
