Colony X-13

Epilogue

It judged started out as a simple science experiment, but it was worse.
The test subject deformed. The other labs had shut down the project. The subjects spread their disease.
They died and came back to life. Soon after they started reanimating, became vicious for blood, grew sharp, sharp teeth and began to learn to hate the outdoors. The next stage of the process was they grew a lot of hair. They learned to run fast. Became carnivores, not just craving brains or blood, but everything off a whole human.
Then they would slowly die and become the undead fully, forever. Unless they are special, then they start to reform into a human. After that, they gain special abilities. These abilities take over the soul, heart, and brain. The people have not just a craving but a need to kill, anything not just mundane humans, but they kill, fangs, furries, biters.
They can't control it, they are overtaken.
People have been living in this world for 20 years. They've learned to fight the biters, most haven't experienced the others, because they started fighting each other in big cities.
It's a hard life living alone, you always need a partner, someone to stick with, or possibly two partners.
He'll with it, maybe even a whole colony.
