Meteors from outer space hit the earth, viruses swept the world, and humans turned into zombies. I was a junior student. When the apocalypse came, I was trapped on campus with my roommates. Water and food were cut off, corpses besieged the city, and despair spread. But we didn't give up. Use the dormitory as a fortress and classmates as comrades to survive in the purgatory-like tide of corpses!
