Survival

The world was gone, taken over by The Infected, creatures that used to be human but now were covered in sores and rotting flesh. With no hope for help, people have been doing everything they could to survive, whether by killing other living or avoiding them all together, whatever was needed to live.
Nathan Carver survived by himself, plus his trusty four legged friend Koda, until they came across a young boy in a cult camp, that sacrificed the children to the gods. Learning quickly that this boy was different from anyone he'd met in the apocalypse, he was immune to the ZX-Virus.
A new goal became apparent, get the boy to a lab to create a cure or at least a vaccine. Along the way the duo met new people, people who joined the group to protect the boy.
