One Shot, One Kill

"Nice Shot. I think you blew off his arm. Shock and blood loss will do the rest."

- Captain MacMillan

One Shot, One Kill is the fourteenth level of Call of Duty 4: Modern Warfare. This is part two of the flashback of one of Captain Price's earlier missions. He and Captain MacMillan must escape to the extraction point.

Synopsis
Price and MacMillan waits patiently on the top floor of a hotel with a sniper rifle for the assassination target, Imran Zakhaev. Lt. Price then takes the shot and dismembers Zakhaev's left arm, but MacMillan states that the shock and blood loss will take care of the rest. A helicopter returns fire, but it's shot down. The two then rappel down the side of the hotel as the top floor is destroyed by missile fire, and continue to escape to the extraction point. They fight through Ultranationalist forces and attempt to lose them through apartment buildings. They are spotted by another helicopter, and it is shot down as well, but crashes toward Price and MacMillan. MacMillan then sprains his ankle and is unable to walk, so Lt. Price must carry him to the landing zone. The two then arrive at the extraction point and wait for the chopper to arrive while fighting off waves of Ultranationalists. After the chopper arrives, Lt. Price and Captain MacMillan are lifted to safety. The fate of Captain MacMillan is left unknown. However, in Sergeant Griggs’ rap at the end of the credits, he says “This one’s for MacMillan, fifteen years you have relaxin'”, suggesting that MacMillan may have retired.

Walkthrough
This is part two of the flashback mission. Don't wait for MacMillan's mark as it is harder the longer you wait. Remember before you fire take the wind into account as you do it - the flag will tell you how hard and in which direction the wind is blowing.

Bullets are changed immensely by the wind, so if you don't shoot him just restart and try again. Your best bet, actually, is to shoot when the wind dies down as Captain MacMillan suggests. This chance presents itself near the very end of the meeting. You'll know when to shoot because MacMillan will panic, saying "It's now or never!". If you see the shot going too wide, try to correct the mistake and fire again. Keep shooting! Also, try to aim for the chest. If you aim for his head, you'll miss and hit the man behind him in the leg.

After you take out Zakaev a helicopter will hover in front of you. Shoot the pilot with your sniper rifle (he's an easy shot) through the glass of his windshield. Firing like crazy is an option if you get frustrated, and does work on the lower difficulties. After killing the pilot (and thereby the helicopter), get off the sniper rifle and start following MacMillan.

Too bad that your cover's now been blown! You need to get on the rope to rappel out of the hotel. From here, follow MacMillan until he reaches a road. All hell breaks loose here as waves of enemies on high alert enter the fight. Use your M21 right away and hopefully take most of them out before they get cover. If you can find a G3 from a dead enemy switch out your pistol for it, as the G3 and M21 share the same ammo type so you may get doubled ammo. If they get cover, either camp them with your sniper or run up to them with your pistol/other automatic weapon and shoot/melee them at close range.

When MacMillan tells you to bolt, sprint like crazy, using your compass to guide you to the apartment. Follow MacMillan as he weaves his way through the apartment. Don't be frightened by the dog as you jump in and out of windows.

Stop like MacMillan when you see the enemies outside. Switch to your Claymores and head over to the end of the room. Here you'll find the door outside; plant the Claymore and sprint back to MacMillan. After the Claymore goes off, run outside and follow MacMillan to an alleyway of sorts.

MacMillan will halt and the two of you will start to fire at the guards coming at the end of the alley. Just switch to your automatic weapon and take them out. Soon a helicopter will appear over the apartments and it starts to charge at you. Switch to your sniper rifle and start unloading bullets into its windshield; you don't get points for accuracy, but sooner or later you'll hit the pilot.

As the helicopter crashes to the ground it wounds Cpt. MacMillan and he can't walk, so you're going to have to carry him. Pick up the injured MacMillan and start walking. Your time should be about seventeen minutes left, but you have plenty of time, so no worries.

With MacMillan in your arms, head west to an alleyway. Drop MacMillan off at the busted car near the stairs and quickly get your sniper rifle out. If you're fast enough, you should be able to snipe the three hostiles running to you from the west. If not, use frags/automatic fire to kill them.

Three enemies will also engage you from the east, making this a two-front battle. Stay behind the staircase or the house wall for cover. When you're done with the troops on the west side, start with the ones on the east side. One should be an easy shot between the staircase and the house; the other is in the brush near a broken car; and the last is hidden in the corner to the left.

Pick up MacMillan and use the yellow indicator to guide you in the right direction down the alley. Instead of trying to kill the two enemies in sight out of the alley, opt to run through the brush and make a mad dash for the apartment.

Take the right doorway and use the debris slope to ascend to the second level. From here, make your way south to the other side of the building. When you get to the middle stairwell and MacMillan asks you to put him down, do so by the door (he can shoot through it) and enter the room.

Just stand still at the doorway and wait until a dog at the far end of the room starts to growl. Down him and try to take the door on the right. Some firing and growling will follow, so make your way back to the first doorway (where MacMillan is at) and shoot the second dog.

Continue infiltrating the base by playing this cat-and-mouse game. There should be one hostile and one dog left. MacMillan will give the "all clear." Run back, pick him up and head to the south part of the building. Exit and head southwest to another building.

Take the right door and go through the locker room/bathroom. Once you reach the pool, you have a couple of options on what to do with the dogs:


 * 1) If you put MacMillan by the side of the pool (not in the pool), the dogs will run outside and kill the two guards there.
 * 2) If you just head outside and pass by the dogs, later, in the beginning of the sniping part, the dogs will run out and attack the incoming enemies. You can use the second option to get a few quick kills as the dogs distract the enemies who are looking for you and kill some of them.

Place MacMillan in the center of the area in front of the wheel and place your last Claymores and put the C4 at the corner of the pool (you will receive MacMillan's equipment and finally get double Claymore and double C4). Claymore the hell out of the area, plugging up the open spaces between the cars.

Run over to the Ferris wheel and you'll learn that a helicopter is coming "soon." It is not really "soon," as you have to wait for what seems like an eternity. Follow the yellow indicator and drop MacMillan off at the yellow glowing area. Claymore again, but put one in front of the door on the right (all whole group will be blown up when they open the door, you will find a laptop in it). In addition, keep a few Claymores and position them on the stairs going up to the Ferris wheel. But the most important is to use the cars as exploding devices.

Go prone at the top of the Ferris wheel and wait for the enemy. Take the first group with your planted C4. This is a long and extremely difficult fight, especially if you are not prepared with Claymores and aren't a good shot with the sniper rifle. Luckily the Claymores should hold off the enemy troops for quite a while from getting too close.

Basically this place is sniper heaven. Snipe and snipe and then snipe again. Kill as many as you possibly can. Inevitably they will start to get through and sometimes go around the Ferris wheel and try to attack you from behind - if that happens quickly switch to your secondary weapon and dispose of them. Another strategy used is to position yourself at the edge of the map at the bumper cars, as they can only come at you from one angle - the Ferris Wheel. Don't worry, the Russians can't see MacMillan. Other than that, snipe, snipe, snipe, and you should be good to go. If the going starts to get especially rough, throw a few flashbangs to buy you some time. The rails around the entrance to the Ferris wheel and the Ferris wheel car itself will provide excellent cover. If you are about to die hide behind the Ferris wheel car for a few seconds to regain your health.

Or, if you aren't the best sniper, and are playing on hardened or veteran, a good tactic is to place all of your Claymores and C4 around the bumper cars, retreat behind the bumper cars and aim toward the Ferris wheel with an AK or G3.

After the CH-46 Sea Knight helicopter arrives, kill anyone in the ticket booth near the Ferris wheel and sprint on over to MacMillan and carry him. Luckily some of your allies will help you by consolidating the helicopter location with troops, so run over to the helicopter as fast as you can, using the booth as cover. When you're inside just fire at enemy troops a little more and the mission ends as you fly away.

Tips



 * When attempting to kill Imran Zakhaev, wait until he raises his arms in frustration (after the first helicopter pass), in a second the wind will drop which is the best time to shoot him.
 * If the wind is blowing completely left (the flag is perpendicular to you and blowing left), then put the dot on the horizontal line that is furthest to the left on Zakhaev's head and vice-versa for if the wind is blowing completely right, and you will get a direct headshot (although you will still only hit his arm.)
 * Only shoot the enemies you need to kill to allow you to get to the next stage.
 * When at the last part of the mission, put Captain MacMillan where he tells you to and go to the nearest booth to your left. It is pink with one window and a door. There is a small ledge on the side. Go prone under that and stay there untill help arrives. All explosions will not affect you if you go all the way in. This tip will work on any difficulty. Confirmed for Xbox 360. It can work on PC, with some occations being immune, others times, not so much.
 * There is a trick allowing you to use your claymores and C4s twice in the final part where you have to survive until the helicopter arrives.When MacMillan tells you to put him down behind the Ferris wheel,put him down anywhere but the Ferris wheel and set out your explosives.After you set them up,put MacMillan in his spot and you will have 10 claymores and 3 C4s again allowing you to set up twice as many explosives.
 * Remember to place MacMillan in a good tactical position to give backup.
 * When at the Ferris wheel, allow Captain MacMillan to cover his side and you cover the other side.
 * Many enemies funnel up the stairs to the Ferris wheel. Make sure they aren't the ones who kill you.
 * The best tactic for Veteran difficulty is to plant all your C4 on the rise behind the Ferris Wheel (because many enemies go prone there and they are hard to see because of the grass), hide behind the bumper car ride, and when the helicopter arrives detonate the C4 and sprint to MacMillan. Before picking him up throw a flashbang to your right to blind any enemies attacking you from the Ferris Wheel. Also, be sure not to plant any claymores too close to the C4 blocks, because when they go off they will take the C4 with them.
 * One easy way to get through this level is hide behind the tree on the right of Macmillan, you can dodge a lot of gunshots there since the tree is thick enough, occasionally there will be one or two guys climbing up the stairs of the ferris wheel or approach from your far right side , but only one at a time, so it's fairly easy, just watch out for any grenades they don't often throw at you.
 * Another easy way to get through the end of the level, is to grab the AK-47 by the car directly in front of where you set down MacMillan, plant C4's and claymores around the ticket booth, hide as far back as you can in the corner in there, go prone, and keep your AK-47 aimed at the door. Close-by grenades (like at the doorway) won't kill you and some rare grenades that make inside will be easy to throw back. Just sit back and relax until the helicopter comes. About a third the time you are blinded by a flashbang an enemy may attack, but, if you keep your gun pointed out the door, you can easy shoot them, and Xbox-360 players may get the Daredevil achievement if an enemy is killed while blinded.
 * After placing Captain MacMillan behind the ferris wheel, a good place to hide (for Veteran difficulty) is in the opposite corner of the map, where you can crouch in a corner behind an apartment building. It is inadvisable to stay there for too long, as you could easily become surrounded, or trapped by grenades. When you get a good opportunity, run towards an alley next to the building with the pool. This alley is where the enemy would normally spawn, but they won't as long as you're there; they'll spawn from other places. This alley is a great place to take cover, as the enemy can only attack you from one direction, and MacMillan will kill a lot of enemies before they come to close to you.
 * If you do use the above tip, make sure you can get to MacMillan in time, as you will be very far from him. When the helicopter comes within 1000 meters, it's time to get moving. Stay cautious, as the last checkpoint was when the helicopter was around 6000 meters away, but don't be afraid to rush towards MacMillan. Once you've picked up MacMillan, your team should be able to hold off any enemy fire, and the mission should be complete.
 * If you stay back in the alley for too long after the helicopter arrives, you may not be able to retrieve MacMillan in time to get to the helicopter before it leaves.
 * There is a glitch where MacMillan stays in the building you sniped Zakhaev in and will not rappel down the ropes. Do this by staying in the building until it explodes then rappel down. He will stay in the building forever.

Enemy Intelligence

 * Laptop 22 is located, like Laptop 21, at the top of a fire escape. It is after the building where you have to sweep the three rooms for enemies. When you exit, immediately turn right and there will be a ladder.
 * Laptop 23 As soon as you drop Captain Macmillan and plant your claymores, stand in front of the place where enemies pour out, when Macmillan says “tangos in sight”, wait until you hear gunfire behind you and rush forward and take a right to find an opened door. The intel is in there, no waiting for helicopters required. The fastest and safest way is to drop MacMillan when you drop down from the pool at the end of the level and throw your C4 around the alley behind you place MacMillan behind the Ferris Wheel and head back over towards where you placed your C4, once he says "Tangos in sight turn around and head for the door it will be open immediately with only two or three enemies to deal with.

Trivia

 * This is definitely the most gory mission in Call of Duty 4 because you can see a body part fly off, and is also the first time in the Call of Duty series that this happens. Also, having the Cockpit of the first helicopter covered in blood once you shoot the pilot. It's also considered to be one of the hardest, as players have to consolidate and defend their positions under heavy enemy resistance (especially on Hardened and Veteran) for a period of time until the extraction helicopter arrives.


 * An Mi-28s cockpit is heavily armored and designed to resist .50 cal rounds, so a bullet shot at the cockpit would just cause damage to the glass and not kill the pilots.


 * No matter which of the Mi-28s operators is shot, the helicopter will always go down. The pilot is seated higher up, while the gunner is seated lower.


 * The Ultranationalists are shown using Mi-28s. Because the mission takes place in 1996, the Mi-28 would not be in rebel hands, as the variant in the game, the Mi-28N was in prototype phases in 1996, and is only recently being delivered to the Russian Army.


 * The Dragunov can be found by shooting the last enemy on the fire escape in "All Ghillied Up" - Note: the gun is often tossed over the low wall when the enemy is shot.


 * If you complete All Ghillied Up and swap out your pistol or M21 for a RPD, G3 or Dragunov (before starting this mission, it (they) will be carried over. For other weapons though (Stinger missiles, G36C, P90) it would be changed to an AK-47 instead.


 * The silencer and ghillie cover from the player's M21 has been removed since the last mission. However, if you start the mission with the pistol it will still have the silencer on it.


 * This level seems to take place about three days after "All Ghillied Up", as you see time fly by during the cut scene.
 * The dogs in the empty swimming pool in the building on the way to the fairground will attack enemies during your defense of the fairground as long as you do not enter the pool before calling for pickup.
 * Also, after startling the pack of dogs in the pool building, if you quickly run through and look at the ending holdout zone you can sometimes see the dogs running over a distant hill.


 * The forward iron sight on the M82A1 is up, this should be flipped down during sniping.


 * If you look closely, the M82 has two sets of bipods; one folded up and one in the down position.


 * Captain MacMillan never carried a M82A1 in the previous level 'All Ghillied Up' or neither does it seem to be carried by Price in the cut scene before 'One Shot One Kill'. It is also unlikely that Price was carrying it during "All Ghillied Up", because trying to sneak past all those Ultranationalists while carrying such a large and heavy weapon would be near impossible. It is possible, however unlikely, that the rifle and ammo was air dropped onto the roof of the building while MacMillan and Price were making their way to the building or during the three days between this mission and the last one. there is also another theory that they took the weapon apart before the mission and re-assembled it at the site.


 * 'One Shot One Kill' is the motto of the U.S. Army Sniper School.


 * When sniping Zakhaev, even with a clean head-shot, the bullet will still rip off his arm.


 * On Game Over, Zakhaev wears the same suit that he wore during the negotiation.


 * It seems that MacMillan is saying "Ah, fuck..." while the subtitles say "Ah, crap..." when the helicopter comes crashing down on him after you snipe it down.


 * If you look into the CH-46 Sea Knight, you'll see that there is no pilot. It's completely empty.


 * At the end of the mission, when the helicopter is waiting for you to get in, it will take off and leave you and MacMillan stranded if you take too long.


 * If you try to board the Sea Knight without carrying MacMillan with you and the time expires, you will clip through the floor of the chopper when it takes off.


 * If you run to the helicopter without MacMillan, one of the Marines will shout at you, "Where's MacMillan?!"


 * The movie "Shooter" bears a slight resemblance to the sniper scene. They start off firing at one or two guys at about 900m when they are compromised and heavily outnumbered. They snipe out a helicopter to save some time, then hightail it. Also, in both the level and the movie, the spotter suffers a helicopter-related injury, killing the spotter in the movie, while only wounding MacMillan.


 * There is a claymore placed by the door in the hotel room at the beginning of the mission, but cannot be blown up.


 * There is another flag on top of the building behind where Zakhaev is having the meeting, however, it just blows in one direction. This may be because it is higher up, and wind speeds sometimes differ at different altitudes. However, it is unknown why this does not affect the shot, as Price fired from a very high altitude.


 * The vehicle Zakhaev gets out of never has anyone in the backseat, even when driving up to the meeting point, which means he spawns behind it. If you miss your shot and alert the Ultranationalists, Zakhaev goes back into the vehicle and there is still no one in the back seat as it drives away.


 * One shot, one kill is also the message that appear in Modern Warfare 2's multiplayer when the player gets a one hit sniper kill.


 * If you play your cards right, you can shoot through Zakhaev and also kill the guy behind him by the car. If you have the "bad year" cheat on for the Xbox 360 and the PS3 the guy explodes into tires but Zakhaev does not. This is because he does not die until Game Over.


 * Even though MacMillan notes multiple variables that would affect the shot, such as the Coriolis effect, the only variable that actually takes effect is wind. This is probably because they would have adjusted the scope to account for the other variables while waiting. Also, even if the bullet appears to overshoot Zakhaev, the Coriolis effect will cause it to turn around and hit Zakhaev.


 * If you glitch outside of the map using the 'noclip' cheat, fly over to the place where Zakhaev is shot, you can see Zakhaev is frozen but his blood keeps spraying, and 2 enemies which will not shoot you on sight, but you can kill them.


 * On the Xbox 360, you can glitch out of the level . If you look closely at Zakhaev's dead body, you can see that he spawned grenades when he "died" just like any other enemy. However, you cannot pick up the grenades. You can also see his dead arm laying on the ground. If you are playing on HD, you can see the brand of suit Zakhaev is wearing by looking closely at the buttons.


 * If you glitch out of the map by using either of the ways above, you can travel to places at the beginning of the level and the end of the previous level. If you go there, you can die of radiation if you aren't careful enough.


 * If you look closely when you shoot the cockpit of the chopper you can see blood spurt out on the glass.


 * When sniping with the M82 if you look behind the target area you can see part of the multiplayer map Pipeline, also on Pipeline if you look closely outside the map from where the grassy area is you can see a tall building, possibly where MacMillan and Price were sniping from.


 * When Macmillan orders you to snipe the helicopter, if you don't have a sniper rifle you will pull out a M21 and use it for the rest of the level. This also happens when he tells you to plant claymores.


 * When you get near the pool before the ferris wheel and press start, the dogs at the bottom of the pool are painted as allies on the HUD, like Cpt. MacMillan. These dogs will not attack you, if you jump down into the pool they will jump out and run off.
 * Sometimes these dogs will attack the enemies coming after you at the Ferris wheel.
 * There is a writing on the tail of attack helicopter, that blocks our view. The writing reads "Горячий цыплёнок" (Hot chicken), possibly the callsign of the chopper.
 * If you stare at the fence behind you when the enemy helicopter crashes, you can see that it is closed with a gate. Do not take your eyes off of it and head backwards to pick up Captain MacMillan. The game will then forcifully make you face MacMillan and now when you get back to the fence the gate is magically gone.
