In 2008, experiments on people were conducted in the black mesa. Experiments to accelerate the response of a person and his adaptation to hostile environment. One of the experimental was Corporal Frankie. Soon he the only survivor of the test subjects and they froze him, counting him too "dangerous subject". In 2009, the black mesa occurred a catastrophe that entailed a seven-hour war and a quick enslavement of people. In 2010, the corporal defrosted the alarm system surviving from the black mesa. The corporal got out of the ruins of the black mesa and discovered a strange blue light teleport hanging right in space. These teleports (portals) of the alliance have remained since seven-hour war, then through them transported the alliance of his soldiers. The corporal went through a teleport and found himself in a deserted German base. Torchwood, now one of the bases of the alliance. (translated)
