It has been years now since the wild beasts took over the world . They might look human, but do not be deceived they are monsters, and they have almost wiped out the entire human race. 'We' are part of the few surviving humans in what was once known as the United States of America. We hide ,we fight for food ,we keep each other safe, and most importantly, we do whatever it takes to survive. They call themselves 'werewolves' ,half man and half beast the most vicious monsters on this planet . Some say they were The First creatures to exist before humans and now they are back to take back the world. Some humans even worship them as Gods.Nobody knows how they came to exist or why ... maybe it's a sign... maybe this is the end of the world.
