Teraphobia — the fear of monsters — has progressed past the point of occasional discomfort. The stress is constant. The feeling of being watched never fully goes away. The monsters that have awakened from the underworld are real, and they were changed by something before they were released: a retired demigod whose modifications made them into something more dangerous than they were. In this psychological co-op horror experience, work together to stop the creatures before they catch you. They cannot be allowed to know you are there.
