CALL OF DUTY (Modern Warfare Remastered) - One Shot One Kill
Lt. Price and Cpt. MacMillan patiently wait on the top floor of the hotel with a Barrett .50cal sniper rifle for 3 days. While the assassination target, Imran Zakhaev, is attempting to sell uranium fuel rods to Russian Ultranationalists, Lt. Price takes the shot and dismembers Zakhaev's left arm. Their cover is blown when an enemy helicopter returns fire, which Price promptly shoots down by sniping the pilot. A second helicopter locates the two and opens fire on the hotel. The two rappel down the side of the hotel as the top floor collapses and continue to escape to the extraction point. It is later revealed that Zakhaev survived this seemingly fatal blow.
They fight through Ultranationalist forces and attempt to lose them through apartment buildings. They are then spotted by another helicopter and they manage to shoot it down, but it crashes toward Price and MacMillan. MacMillan's leg is injured by the helicopter's debris and is unable to walk, so Lt. Price must carry him to the landing zone. When they arrive at the extraction point which is at the ferris wheel in Pripyat Amusement park, and wait for the chopper to arrive, waves of Ultranationalists retaliate.
They hold off until the chopper arrives, and Lt. Price and Captain MacMillan are lifted to safety.
