The scientist have found a way to blend human and animal DNA. The government has agreed to fund this experiment. The question was where to get volunteers. After much discussion it is agreed to offer the option to young criminals as away to avoid jail and turn their lives around. As one of these young criminals you will have to learn to control your animal instincts and learn to change at will. If you survive the training you will became a soldier defending the United States. The teens are kept an apartment complex that was built underground. This was to keep the project hidden until the teens had control of their animals and were trained. It was understood that the teens would do exactly what they were told or they would be destroyed. They would be tested and educated. It was hoped that they could become the soldiers of the future saving others. They would do the missions deemed too dangerous for ordinary soldiers.
