Behind Roach, along with the old acquaintance Soap MacTavish, you will reach Kamchatka. You peek behind the walls of the gulag or experience the assassination of the civilian population. There will be an attack by Russian troops on the American mainland and fate will spin the carousel of misery in one single expectation - the War.
