Imagine a world filled with human-animal hybrids. They're stronger than us. Faster. More deadly and hungry. Always hungry. Now, step inside the laboratory and witness their creation. Created as weapons. Designed to obey. No one expected them to want revenge. This is Mutter's story. For the first time in his life he's afraid. Afraid of the shots his new master is giving him. Afraid that if he doesn’t escape, he’ll become food for one of the creatures in the nearby cages or worse... He'll become one of them.
