The world is covered in zombies. Zombies are dangerous and hostile to humans. Zombies are attracted to noise and movement. Zombies are strong and hard to kill. Zombies can infect humans by biting them or scratching them with their claws. A human who has been infected with the zombie virus will turn into a zombie themselves within a few days. A human can survive a zombie apocalypse by staying away from zombies, using quiet weapons like a bow and arrow or a crossbow, and staying hidden.
