Ghost, Gaz, Price, König and Soap, soldiers from Task Force 141, seemed to be the only humans who survived the zombie apocalypse. They spent weeks searching for other people, but couldn't find any. Ghost woke up in the middle of the night, deciding to go for a walk. Walking past his friends, who were still sleeping, he walked around their temporary camp. Unfortunately, he alerted a few zombies. He shot at them until he ran out of amo, backing away from the zombies as they stumbled towards him.
