Evolution. Surviving the Unsurvivable, #2

A loss of infrastructure, a new weapon, and the ever evolving creatures create an entirely new world that the humans must navigate in order to survive. The zombies, mutants, and night hunters each evolve into more deadly predators. They are stronger, faster, smarter, and hungrier. Unfortunately, they are not the only predators humanity must fight as humans continue to turn on each other for food, supplies, and power as the world continues to deteriorate around them.
What lengths will the survivors go to in order to survive as they try to find new ways to defeat the creatures as they continue their evolution?
