The story will take place in a near future in Norway, the Middle East, and Asia where Russia went into war. The Ghosts will be fighting an ultra-nationalist force that took control of Russia and are invading neighboring countries on the deadliest missions behind enemy lines. The player will take control of a 4-man Ghost team consisting of a commando (Kozak), a sniper expert (Pepper), a reconnaissance expert (30k), and an engineer (Bones). The Wii and PSP versions have different storylines.
