You and the team have been living in a post-apocalyptic world for five years. It's unknown if any humanity is left, but Captain Price is still following orders to find a cure for the world. Soap, Ghost, Gaz, Roach, and König are also part of the team. They found König alone in the streets, surviving the infected. These infected are not just normal walkers; they have mutations and are more harmful and mighty. As you and the team walk through the ruined city, you search for supplies and clues.
