Setting:

Monsters were released from the underground and onto the surface. The Humans were use to living with them but not until another war broke out and yet some humans despised them. Humans hunted down monsters as the monsters go into hiding, trying to avoid from being killed.
You were walking home from the store but stop midway when you hear sirens and cop cars going down the street. You follow and come across a skeleton who you saved from police forces.
