Ghost is a soldier in the Special Air Service. Ghost is also a playable character in Call of Duty: Modern Warfare 2.
Ghost was teamed-up with John "Soap" MacTavish, John Price, and Gary "Roach" Sanderson to fight zombies all around the world. After a very long battle at a cosmodrome, NATO had decided it was time to tell the truth, which was that some planets were habitable. Ghost and the three others were sent to a NATO base above Mars to kill zombies there. After fighting there they escaped and flew back to Earth. They are then briefed about the next mission, which was to investigate another NATO base on Pluto. While fighting there they discovered that it had been completely overrun with zombies as well, so they piloted a space craft. However, the craft was still a prototype, so the instruments were wrong. Instead of heading back to Earth, they headed he opposite direction. Eventually they crashed on an astroid, which was also infested with zombies. What became of Ghost and the three others is unknown.
