In the apocalypse, how long could you survive? And how would you stay alive?
In the year XXXX, a large-scale infectious disease plunged the whole world into endless darkness. They say it began when a crow ate rotten meat contaminated with a pathogen, became infected, and then attacked people on the street, giving rise to this tragedy. "Zombies" should have existed only in movies, but who would have thought they would appear in real life? The infected became beings unable to think or control their destructive urges. They attacked their living fellow humans without hesitation, and anyone bitten and eaten by the zombies turned into one as well.
