- "A shot at that distance is tough in the best conditions. That day we had wind gusts and prowling helicopters. And even if we made the shot, we still had to get to the extraction point alive. If it was going to be easy, they wouldn't have called us."
- — Call of Duty: Modern Warfare Remastered level description
- "Target down. I think you blew off his arm. Shock and blood loss will take care of the rest."
- — Captain MacMillan after the player snipes Imran Zakhaev.
One Shot, One Kill is the fourteenth (chronologically, the second) mission of Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare Remastered, and is part two of Captain Price's flashback to Pripyat. It takes place 3 days after the events of "All Ghillied Up". It sees Lieutenant Price and Captain MacMillan snipe Imran Zakhaev and then escape from Pripyat. It also appears in a flashback during Call of Duty: Modern Warfare 3, when playable character Yuri witnesses the assassination attempt by Price and MacMillan, and the rescue of Imran Zakhaev by Vladimir Makarov.
- John Price (playable)
- MacMillan (W.I.A.)
- Imran Zakhaev (W.I.A.)
- Yuri (MW Remastered Easter Egg, and playable in "Blood Brothers" flashback)
- Vladimir Makarov (MW Remastered Easter Egg (Alive/K.I.A., player-determined), and "Blood Brothers" flashback)
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.
Call of Duty: Modern Warfare 3
During the flashback to "One Shot, One Kill" in "Blood Brothers", Yuri witnesses the attempted assassination from the back seat of a car driven by Makarov. After getting his arm blown off, Zahkaev makes a break for the car and the trio flees, running over a few of Makarov's men without care as the flashback ends. Interestingly, some of the weapons seen in the mission (Mini-Uzi, W1200, G3) are not seen on the tables present, which are still in view of Yuri.
If the player swaps their USP .45 for the following in "All Ghillied Up", they will start with that. Certain weapons, such as the P90, G36C and FIM-92 Stinger will not transfer and are replaced by an AK-47.
|Found in level|
- Laptop 22 is located, like Laptop 21, at the top of a fire escape. It is after the building where one has to sweep the three rooms for enemies. When exiting, immediately turn right and there will be a ladder.
- Laptop 23 is rather difficult to get, as the door leading to it is initially closed. To open it, the player must force hostiles to spawn on the other side of the door. To do this, run to where the enemy usually enters the area from once MacMillan calls the Sea Knight; two or three hostiles will spawn in the hallway on the other side of the door and open it. Enter the hallway through that door, and the laptop will be at the far left corner.
- The map loading bar at the bottom of the screen at the beginning of the mission is green in color instead of the usual white as with every other mission.
- If the player had swapped their USP .45 for another weapon in All Ghillied Up, the weapon will become an AK-47 in this mission. However, if the player had an AK-47, they would receive their USP .45 back. This was changed in the Remastered version where the player will keep their weapons from previous mission should they have started from there and swapped them or not.
- If the player has swapped their USP .45 for a Dragunov, with the M21 Suppressed still intact in the previous mission, in this mission they will only get the Dragunov; no secondary weapons (tested on PC).
- The Barrett 50. Cal the player uses in the beginning has two sets of bipods, one folded with the other being unfolded.
- If the player looks into the CH-46 Sea Knight, they will see that there is no pilot.
- If the player tries to board the Sea Knight without carrying MacMillan and the time expires, the player will clip through the floor of the chopper when it takes off.
- If the player goes to the drop point in the small hills near a radiation zone where the troops come out of the first Mi-8 helicopter at the end of the mission, the player will notice that they land beneath the hill, since they will have half their body clipping through the ground.
- There is writing on the tail of the attack helicopter that blocks the player's view. The writing reads "Горячий цыплёнок" (Hot chicken).
- Despite the mission's picture showing the helicopter crashing toward MacMillan in an open area, it actually crashes toward him in an enclosed area in the mission.
- If the player shoots and destroys the helicopter moments after Zakhaev's arm blew off, it will not give points for destroying the helicopter in Arcade Mode.
- The Attack Dogs from the abandoned swimming pool building will attack the enemies if a hostile gets hit at the beginning of the extraction hold out.
- If the player was playing on a harder difficulty, the helicopter will take longer to arrive.
- If the player shoots the Barrett to the outside of the meeting, such as the roof to the far left, the wind will not affect the bullet's flightpath.
- If the player stands next to where the chopper blade hits MacMillan one will see that the helicopter doesn't actually touch MacMillan.
- The Mi-8 helicopters that bring reinforcements to the extraction point are invincible.
- It is possible to walk on the rotors of the crashed Mi-28 Havoc, even when holding MacMillan.
- If the player kept the M21 from the previous level, they will notice that it misses its ghillie camo and the suppressor that it had in "All Ghillied Up". In the Remastered edition, should the player keep said M21, it will still have the ghillie camo and suppressor.
- In the PS3 version, when the helicopter encountered at the playground appears, Captain MacMillan says "Ah bollocks, run!!", but the subtitles states that he says "Ah crap, run!!".
- In the Remastered version of the campaign, there is a trophy called Time Paradox that can be obtained. If the player looks closely at the jeep to left of Zakhaev, they will find Vladimir Makarov and Yuri talking. If both Zakhaev and Makarov are shot, the player will gain the trophy. Killing Yuri, on the other hand, gives the player the "Friendly fire will not be tolerated" message.
- In the Remastered version of the Arcade Mode, killing Makarov will not reward the player with points.
- Piggyback Ride (20) - Complete "One Shot, One Kill" on any difficulty.
- The Shot (40) - Complete "All Ghillied Up" and "One Shot, One Kill" on Veteran difficulty.
- Time Paradox (20/Bronze Trophy ) - Kill Makarov and complete your mission.
