The end of the world is approaching, the aberrant virus is ravaging all living beings, and human civilization is in danger. I broke into an abandoned hospital in search of a girl, was surrounded by monsters, witnessed changes in my loved ones, awakened the system in a desperate situation, became the director of an underground shelter, and shouldered the heavy responsibility of restoring hope for mankind! CEOs, electricians, programmers and other professional people will have no place to live in the end of the world? Don't be afraid, come to my system shelter to help me survive and rebuild, we need you!
