The player starts the mission on a fast attack helicopter, as three Little Birds converge on a Russian Gulag while F-15s destroy a SAM (surface-to-air missile) site on a nearby ridge. As the player's Little Bird flies over the gulag, the player can snipe the soldiers on the towers.
After the landing, player will fight in a courtyard filled with enemies.
Eventually the player will come across a control room where Ghost will take control. After that, player will be assigned to a "cell duty". After killing all the enemies, player will arrive to the armory.
Once inside the armory, Captain MacTavish will sarcastically ask if there's a weapon that player likes. Of course, you have the choice of swapping for a weapon the player likes. Enemies will encircle the armory, so Soap will tell the player to shields to use one of the riot shields that are lying around the armory. When all of the cell blocks are cleared, player will rappel down to the lowest floor.
After that, player will fight to the shower rooms.
After clearing the shower room, team will advance to rescue the Prisoner 627, that is revealed to be Captain Price, captured during the events of Operation Kingfish. MacTavish orders him to drop the weapon, and old friends are reunited.
Then the player must hurry to reach the exfil point, where cave-in drops on player; however Price will free the player and team will escape the castle with a SPIE rig that is attached to a Pave Low.
