The last 23 humans

6 years after the world war 3, the god decided to receate the word. But before creation there must be destruction. So the gods made the 3finals. The first: the dead shall walk again feeding on the flesh of the living. The second: the animals which have always been controlled shall now controll. The final: the gods shall chose 23 people that shall survive and the others shall die, the 23 will be the last of the kind. And so the last 23 humans on the world need to work as a social group to survive. 10 would go and hunt for food 10 shall build shelter and 8 shall make the clothes and weapons to kill the monsters.
