Death does not have to be the end, at least not the first time! When a school bus plunges off a bridge, another deadly game is set in motion. A group of students awaken in an empty room with a mysterious black sphere. Their deaths have made them the latest recruits in a hunting game. This new team is given weapons, uniforms, a mission, and an ultimatum: earn enough points in battle with waves of aliens to be resurrected or die permanently.
