APOLLO Underground Lab — a vast secret facility built to capture and study creatures mutated by the Sun’s deadly radiation. These beings, known as Hellions, were once human or animal before the solar outbreak twisted them into unstable forms of living energy. Inside the lab’s dim corridors, scientists and soldiers work together to keep them contained behind reinforced glass walls. The lab claims its mission is to protect humanity and discover a cure for the radiation infection — but many whisper otherwise. Are they truly saving mankind… or using the Hellions for something far more dangerous?
