''Call of Duty'' (Or [=CoD=] when abbreviated) is a series of FirstPersonShooter games created as the SpiritualSuccessor to ''VideoGame/MedalOfHonor: Allied Assault'' after the exodus of some 2015Inc. staff, who would go on to form Infinity Ward. The series is developed mostly by either Infinity Ward or Treyarch and published by Activision, famed for its immersive storytelling techniques and engaging multiplayer mode. So far, the series has appeared on the PC and has also appeared on most major consoles and handhelds. A {{card game|s}} has also been announced.

The first three main installments took place during UsefulNotes/WorldWarII and garnered acclaim from the entertainment press. Then came ''Call of Duty 4: VideoGame/ModernWarfare''. The setting for the game, indicated by its sub-title, was drastically different from the previous entries and the campaign's plot is about the United States, United Kingdom, Russia, and the Middle East tied to a nuclear weapons plot. It was a massive commercial blockbuster for Activision and won several awards (including Game of the Year). Soon afterward, a spin-off, ''World at War'' (sometimes referred to simply as ''Call of Duty 5''), brought the series back to its roots as a World War II shooter. ''Modern Warfare 2'' (alternatively "Call of Duty 6") reverted to the modern setting introduced in ''[=CoD4=]''. While the game has been well received by major reviewers and console gamers, PC gamers [[InternetBackdraft were upset over the removal of dedicated servers]], which resulted in the loss of {{game mod}}s and being able to pick one's own server (let alone administrate them), and the reduction of the number of players to 18 per server. In addition, it sold around 3.3 million copies within 24 hours.

This record would be broken by ''VideoGame/CallOfDutyBlackOps''. The story centers on Alex Mason, an American squad leader who is probed on his exploits in Cuba, Vietnam, and other areas. Oh, [[WinBackTheCrowd and the PC version has dedicated servers and game mods again]]. Its position as the fastest-grossing (and fastest-selling) video game of all time was conquered by ''Modern Warfare 3'', released to a less-than-stellar critical reception when Activision and Infinity Ward made legal action against each other, which in turn was surpassed by ''[[VideoGame/CallOfDutyBlackOps2 Black Ops II]]'', [[TwentyMinutesInTheFuture partially set in 2025]] with {{flashback}}s from the final years of the Cold War. The latest game is ''VideoGame/CallOfDutyGhosts'', with an all new story taking place after an unknown catastrophic global event.

On May 2nd 2014, Activison released the trailer for the eleventh game in the series, ''Advanced Warfare''. The game stars {{Kevin Spacey}} as the main antagonist, and takes place far in the future, where the world's most powerful military is not a country, but a corporation. The trailer has shown futuristic elements such as hoverbikes and mech suits, and can be seen [[https://www.youtube.com/watch?v=sFu5qXMuaJU here]]

Though the series earned early fame as one of the finest WWII shooters on the PC, it didn't really take off on consoles until the fourth installment. Most games in the series since then have consistently set their own record for the largest launch in entertainment history.

Warning: This game series may make you want to apply to the ''actual'' American/British/Russian military. Further warning: If you do, [[ThisIsReality there are no respawn points.]]

'''Please add any examples relating to the ''VideoGame/ModernWarfare'' sub-series, ''VideoGame/CallOfDutyBlackOps'', ''VideoGame/CallOfDutyBlackOps2'', ''VideoGame/CallOfDutyGhosts'', or ''VideoGame/CallOfDutyAdvancedWarfare'' to their dedicated pages[[note]]unless, of course, they also apply to the main series[[/note]]. Likewise, add tropes relevant to Nazi Zombies in... well, VideoGame/NaziZombies.'''
----
!!This series provides examples of:
* AcceptableBreakFromReality: We're not sure how Japanese soldiers get a hold of Russian machine guns and prototype Nazi rifles in the ''World at War'' multiplayer mode, but hey, RuleOfFun.
* ActionGirl: The Communists have female combat infantry (although not in the first game). ''Finest Hour'' even has a female sniper (Tanya Pavelovna) as one of the player characters.
* AddedAlliterativeAppeal: Commissar Markhov's RousingSpeech before the assault in the Ring Of Steel mission of ''World at War''.
-->''"On the Führer's birthday... A barrage of Katyushka rockets will tear Berlin to pieces. With your bullets... With your bayonets... With your bare hands... Do the same to their wretched soldiers!" ''
** Another Russian soldier gets at it in the first game as a BondOneLiner: "You can heil Hitler in Hell!"
* AKA47: Averted; most weapons appear with their real names.
** Oddly played straight due to a possible bug in ''Call of Duty 2'': the Gewehr 43 with a scope is referred to as the Springfield in singleplayer.
** ''Black Ops'' has an odd example in the singleplayer appearance of the Grim Reaper, where Bowman will actually call it by its real name when telling you to pick it up.
* TheAlliance: The Allies of course. For the most part they're made of the Americans, the British and the Soviets but at some points, Canadians, Poles, French and Dutchmen appears to join the fight. Their counterpart are the Axis Nations. For 85-90% of the series they're made of Germans but other nations appears as well, In ''Big Red One'' Vichy French and Italians appears and in ''World at War'' the Japanese appear.
* AmericanArmedForces
* AmericaSavesTheDay: Subverted in ''World at War'', which presents the American Marine Raiders as dying constantly and being ground down by the Japanese troops' tactics despite the eventual progress of their forces. The protagonist and his battle group are eventually sent home after taking a castle - but the war is not presented as being over by their hands; the Russians' have the final missions in the game and take the Reichstag.
** Yet the missions are presented in AnachronicOrder, the Reichstag fell a month before the events of the final Marine missions, meaning the war technically really ''did'' end with the Marine Campaign.
* AmericaWinsTheWar: [[AvertedTrope Mostly averted]], in that the WWII installments usually let you see the conflict from the British (except in ''World at War'') and Soviet sides as well.
** Also averted insofar they show all three major Allied nations' contribution to the war effort. The first and fifth games even end with the player leading a squad of Russian soldiers on the final assault on the Reichstag (German parliament) in Berlin.
** ''Call of Duty: Big Red One'', however, IS this trope. You follow the Big Red One from the sands of North Africa to the borders of Germany, kicking the collective asses of the entire Vichy French, Italian, and German Armies with no mention of any of the other allied nations.
*** With the game focusing entirely on the 1st Infantry Division (U.S.), this trope is probably justified.
** Call of Duty 3 also had you play from some Polish and Canadian troops' perspectives.
** ''World at War'' has you play as Americans in the Pacific - but their segment ends with them going home before the war is over, with the final part of the game showing the Russians taking the Reichstag (though, as above, note that the Reichstag mission took place [[AnachronicOrder several weeks]] before the final Marine missions on Okinawa; the game also ends with footage of the atomic bombs being dropped on Japan, after which the war really did end).
** Also subverted in the ''Modern Warfare'' series, where [[spoiler:the British are responsible for killing Zakhaev]], and at the end of ''Modern Warfare 2'' [[spoiler:the war with Russia is still ongoing despite Shepherd's death.]] ''Modern Warfare 3'' plays it semi-straight: [[spoiler:while the war officially ends with the rescue of the Russian President's daughter by US forces, they're assisted by Captain Price and Yuri, who go on to kill Makarov and what remains of his inner circle.]]
** ''Ghosts'' shoots for the inversion. By the time the events of the game start, the US has already ''lost'' the war. Devastated by the surprise attack from South America, the country was left without a good enough military to ward off the subsequent invasion. The Ghost unit's ultimate goal is to hopefully reverse this and win back their country.
* AnachronismStew[=/=]WeaponsUnderstudies: Destroyed King Tigers can be found "Vendetta" in ''World at War''. They're never used in the Battle of Stalingrad, and didn't even exist until one year later.
* AnyoneCanDie: It became official in ''Call of Duty 2: Big Red One'' and oh, and how they do. Oddly enough, averted in ''Call of Duty 2'', where none of your named allies die.
** Killed NPC's include: [[spoiler:[=CoD1=]'s Price, Elder (depends on the player), Sullivan, Chernov, Roebuck or Polonsky, Woods ([[BackFromTheDead except not]]), Bowman and Reznov]].
* ArbitraryMinimumRange: Players can use grenade launchers. In most cases, the grenades have to travel a minimum distance before they'll explode, meaning that if someone is too close to you, the grenade will simply bounce harmlessly off the ground or wall next to them. Fortunately, you can usually still get a kill with a direct impact.
* ArrowCam: The Kill Cam in the multiplayer, an anti-cheating feature which shows the POV of the player who just killed you. [[OlderThanTheyThink This feature has been around since the first game]].
* AttackAttackAttack: Literally posted on a sign in the FIRST scene in the first game; it's a sneaky way to tell the player "always move forward or the RespawningEnemies will overrun you".
* AuthorityEqualsAsskicking: ''World at War'' has Sgt. Sullivan [[spoiler:until the end of the second mission]], Cpl./Sgt. Roebuck, and Pvt. Polonsky. (Roebuck and Polonsky are a special case in that [[spoiler:one of them will die at Shuri Castle, although the only difference is an achievement if Roebuck lives, and the player getting a promotion if he doesn't]].)
** ''Black Ops'' does this to Reznov, who was apparently made Captain near the end of the war, by the time [[spoiler:you play as him in "Project Nova".]]
* {{Autosave}}: Most games save between levels, and some save at checkpoints.
* AwesomeButImpractical: The MG 42 & FG 42 in most cases. Fun to use, but it runs out of ammunition very quickly and it's rare to find replacement ammo. Especially impractical when most of the guns can kill an enemy in 1-4 shots anyway (or just one good one to the head). The former also slows you down.
** Large capacity machine guns in general fall into this. While their firepower is nice, they generally have a really long reload time compared to regular assault rifles, to the point that you can be quite vulnerable in the time it takes you to reload said machine gun if caught out in the open with no cover to hide behind.
* {{Badass}}: It's a game about the scrotum-crushing badasses who fought WWII.
** In the Easy Detail level of Call of Duty: Big Red One, five guys take on an entire division. And win.
** BadassBoast: Commissar Markhov makes one in World at War, over a loudspeaker:
--> '''Citizens of Berlin! A ring of steel surrounds your rotten city! We will crush all who dare resist the will of the Red Army! Abandon your posts! Abandon your homes! Abandon! All! Hope! URA!!!'''
** BadassDriver: Sgt. Moody and Pvt. Elder both do a little of this in first game, Pvt. [=MacGregor=] does this at least twice in the second game.
* BagOfSpilling: Compared to the later games, the original games very rarely indulged in this - missions that took place one after another let you keep what you previously had.
* BattleshipRaid: One of the original game's most ignored achievements was recreating the entire 830-foot ''Tirpitz'' in the [=iD=] Tech 3 engine.
* BayonetYa: One of the attachments for weapons in ''[=WaW=]'' is a bayonet.
* {{BFG}}:
** Quite a few in the various games, though the biggest would be any time you're handed an anti-aircraft gun; ''Call of Duty'' had you handle a [=FlaK=] 37 (normal crew: 10) solo and not from the side the elevation and traverse wheels are on, and a [=FlaK=] 30 quad with a normal crew of 8. The 25mm Type 96 triple in ''World at War'' would normally have a crew of nine.
** The example in ''United Offensive'' was done to keep people with infinite ammo tanks from ruining the multiplayer.
** ''World at War'' has crew-served machine guns such as the [=M1919=] and MG 42 that you can fire from the hip. Extra silliness point for including the PTRS 41 anti-tank rifle as a sniper rifle[[note]]Actually used by Soviet sniper Vasili Zaitsev during the war, against bunkers, though he likely wasn't exactly firing it without support like you can in-game[[/note]] that you can carry as if it was nothing.
** ''Black Ops'' introduces [[NamesToRunAwayFromReallyFast the Death Machine and Grim Reaper]], respectively a man-portable [[GatlingGood gatling gun]] and a [[ThereIsNoKillLikeOverKill quad-barreled]], [[KillItWithFire incendiary]] rocket launcher. Both appear briefly in the single player and are obtainable from care packages in multiplayer.
* BlackAndGrayMorality[=/=]GrayAndGrayMorality: The Soviet Campaign in ''World At War,'' puts your teammates, (and by choice, yourself) in a gray territory. Granted, the Germans did rape their way through Russia,but it is shown that many of the soldiers you capture and kill are human beings.
** In addition, during the capture of Berlin, the narration points out that many of the soldiers you're fighting against, though [[YouALLLookFamiliar identical in appearance]], are old men, young boys and the mentally ill forced into battle at gunpoint.
* BloodierAndGorier: ''Modern Warfare'' was like this to the previous games, bumping the rating up to an M. ''World at War'' cranked up the gore, including dismemberment. And ''Black Ops'' is easily the most graphic and brutal ''Call of Duty'' yet.
** ''Black Ops'' has scenes which deliberately amp up the horrific mutilations, particularly in pre-scripted melee kills and sections such as the VC "Rat Hole". The latter sequence has Mason wielding a Colt Python in close quarters, and every shot fired grotesquely rends limbs and sends victims sprawling as they clutch at ruined stumps. The Python has no such effect outside of this situation, and [[RatedMForMoney without such sequences the game would have received a 16+ rating at most]]. The player can choose to dial back the gratuitous sections at the start of the game. Strangely enough, averted in the multiplayer, which has no gibs whatsoever (compare World at War).
* BookEnds: ''World at War'', the very last WWII ''Call of Duty'' game, ends the exact same way the original ''Call of Duty'' did; with the Russian assault on the Reichstag and raising the Russian flag over the roof of the seat of German government.
* BoringButPractical: The WWII games have plenty of gun options to choose from, from both Allies and Axis origins. But in all games, the Kar98k + MP40 combo is second to none, as they're both very reliable guns that cover both short- and long-ranged combat and, since so many Jerries carry these two, they're super easy to obtain and ammo is a non-issue.
%%The MP 40 in the WWII series. Accurate, plenty of ammo, acceptable fire rate and tied with the much rarer Sten for second-highest magazine capacity. You will very quickly find this to be your weapon of choice most of the time.
* BrokenFaceplate: One mission in ''Black Ops'' requires you to wear an NBC suit during a chemical attack. You're still fighting, though, and as you take damage, your faceshield will crack. While your regular health will regenerate normally, your faceshield won't, meaning that if you take too much damage in the entire sequence, you'll die from exposure to the chemical agent.
* BottomlessMagazines: The [[FireBreathingWeapon flamethrower]] in ''World at War'' never runs out of fuel, though it can overheat.
** This also applies to mounted machineguns and vehicular weapons. Only the armoured car guns overheat, though.
* CallBack: One of the soldiers in Call of Duty during the battle of the Reichstag can be called Private Petrenko. The main Russian character in World at War is Dimitiri Petrenko making a nice continuity.
** The call back extends to ''Modern Warfare 3'', where one of the generic FSO agents you can fight alongside in the first half of the mission "Turbulence" is named Dmitri Petrenko.
* CaptainObvious: Private Chernov in ''World at War'': "But sir, these men are already bleeding to death!" "Sergeant Reznov! You seem to relish in the slaughter!" "Our rockets are tearing the city apart!"
* CherryTapping: It is possible to kill an opponent by hitting them with a grenade (not the explosion, but the ''grenade itself'' smacking into them) if their health is low enough.
** It is also possible to kill an enemy with a flash grenade in the same manner. You can one-shot people if you hit them in the face in this manner.
*** Flash Grenades actually do around 10 damage against 100 HP people when they explode. You don't need a direct hit, just throw one at a sufficiently-injured person's foot and they might die.
* ColdBloodedTorture: The opening to ''World At War'' has your character witness his fellow private, who is amusingly named [[Film/FullMetalJacket Private Pyle]], being beaten with a bamboo cane and then burned in the eye with a cigarette. The torturer then cuts his throat with a knife, and goes to do the same to you, but you are then rescued.
** Vorkuta... implied, at least.
** Goes beyond mere implications for Hudson and Clarke in "Numbers", though; YOU, Mr. Player, get to give the good Dr. a nice piece of glass candy.
** In Black Ops 2, [[spoiler: [[DragonTheirFeet Kravchenko]] gets this from Woods, before being killed by either a still-slightly-crazy Mason or Woods. In another mission, [[HeroKiller Menendez]] does this to Hudson and Woods later on, in ''Suffer With Me'' both of whom get kneecapped, and then Hudson's throat is slit, with an amulet on a necklace no less.]]
* ColdFlames: Fire is often present in small amounts (think burning wreckage) but entirely cosmetic. A player can stand next to or even ''in'' it and suffer no damage.
* ColdSniper: Sergeant Reznov in ''World at War'' was a ColdSniper until just before Pvt. Petrenko meets him; wounds to his right hand mean that he can't handle a sniper rifle anymore, so he gives it to you and takes up a [=PPSh=]-41 submachine gun. He manages to maintain the general ''attitude'' of one though, until you've gotten the [[spoiler:solitary German sniper]], then he drops it for SergeantRock once you're performing overwatch for the Soviet counterattack and especially when you down the high value target, ''especially'' if you did so with a pistol for the "Gunslinger" Achievement.
** Straight and subverted with the playable Russian character Sergeant Alexei Ivanovich Voronin in the first game. He is pretty much based on Vasily Zaitsev from ''Film/EnemyAtTheGates''. Just like him, he is forced to cross the Volga river while some of his comrades are shot to death for retreating, has to attack machine guns with just some ammo clips, finds a rifle during an attack on German position around Red Square and with it, snipes some German officers. He later fights at Pavlov's house, in Stalingrad's sewers, transfers to the 2nd Guards Tank Division, take part in Battle of Warsaw and later Battle of Berlin. After the conquest of the Reichstag, he wrote a letter to his mother, telling her of Nazi Germany's defeat and how he met American soldiers. He finishes the letter with ''[[CrowningMomentOfHeartwarming We crossed the Elbe River and I shook hands with an American soldier. Although I could not understand a word he said, I felt this man was my brother. And I think he felt the same]]''.
* ContinueYourMissionDammit: First Call of Duty: "Martin! Over here! Get in the car!"
** "Ser-geant Evans! Light up those bloody Stukas that aren't in bloody range yet with the bloody flak gun!"
** Captain Price in Modern Warfare. "On your feet, soldier! We. Are. LEAVING!" during Crew Expendable and "You're still in one piece, get up!" during Hunted: both times after getting knocked out or stunned.
** Just about everything Gaz says in the ''Modern Warfare'' level Heat. "Soap, we're falling back to the next phase line! Let's go! Let's go! You're gonna get left behind!" "FALL BACK! ''FALL BACK!!''"
* ControllableHelplessness: Used to the point of irritation in ''World at War''. You start the game as an American POW watching the Japanese torture and execute your squadmate, and in every other level or so that follows, there's a point in which your character gets his ass kicked after then being pulled to safety by the sergeant. Even more so in the Soviet campaign. Finally, both campaign stories end with this: the U.S. Marine campaign ends with [[spoiler:you having to choose whether it's Sgt. Roebuck or Pvt. Polonsky who survives right before fending off a humongous Japanese counterattack -- your weapon was lowered before the choice had to be made, so you can't simply shoot the Japanese beforehand --]] and the Soviet campaign ends with [[spoiler:Pvt. Petrenko being shot as he charges at the Reichstag flagpole, and having to be helped up to slowly make his way to it]].
* CoolGuns: Kind of goes without saying.
* CriticalExistenceFailure: You've been shot twice? Hide and WalkItOff. You've been shot ''three'' times? HaveANiceDeath!
** This only applies to the player character - enemies do generally react about how you'd expect when they take a bullet that isn't {{instant death|Bullet}}. Sometimes they even get back up after appearing to die, to either [[DefiantToTheEnd fire at you with their pistol]] or just try to crawl away.
* CutsceneIncompetence: In the ending of ''World at War'', your character, an invincible, all-powerful Russian god of war who more or less wiped out the German Army [[OneManArmy by himself]] is [[spoiler: severely and seemingly mortally wounded by a single 9mm bullet fired from an injured German soldier's pistol.]]
** He also has an alarming habit of starting missions lying in a heap.
* DarkerAndEdgier: ''World at War'' goes into this from ''Call of Duty 4''. ''Call of Duty 4'' was in itself a ''DarkerAndEdgier'' version of the rest of the series, while ''World at War'' went down the BloodierAndGorier route for UsefulNotes/WorldWarII with the Pacific Campaign, as well as a very graphic take on the Eastern Front.
** And ''Black Ops'' is the darkest one yet. It even has a [[spoiler: playable torture scene, where ''you'' are the torturer!]]
* DeadCharacterWalking: The game has occasional glitches with corpses, from just silently talking faces to really strange animation and postures. [[http://www.cracked.com/article_19507_the-8-creepiest-glitches-hidden-in-popular-video-games.html This Cracked page explains it.]]
* DeadlyEuphemism: When Commissar Letlev says he'll "take care" of the guest.
* DeathIsDramatic: Averted with [[spoiler: Captain Price]]'s death in the first game. He dies defending a chokepoint while you're in another room, and the game does absolutely nothing to draw your attention to his death. The only indicator is his body on the floor, which is really easy to miss since his corpse is usually buried under a pile of dead Germans. It's entirely possible to get to the end of the mission without realizing he's been killed, until the exfil driver mentions his death.
* TheDevTeamThinksOfEverything: [[TheDevTeamThinksOfEverything/CallOfDuty Here]].
* DifficultySpike: ''Roads to Victory'''s Hunner Park level is ''very hard'' when compared to other levels in the American campaign. The enemy AI is considerably tougher too; they will either [[GangUpOnTheHuman gang up on you]] or spam lots of grenades as soon as they see you.
* DummiedOut: There are files found in ''World at War'' that hint at both a campaign related to British forces and requisite British weapons, but these are nowhere to be seen in the final product.
* EarlyInstallmentWeirdness:
** The original ''Call of Duty'' and its expansion ''United Offensive'' had more in common with ''MedalOfHonor Allied Assault'' and other ''Quake 3''-engine games than later ''Call of Duty'' games. There was a health bar that could only be replenished by picking up health packs, you carried a pistol in addition to the usual 2 weapon slots, grenades had to be equipped and couldn't be quick-thrown, checkpoints were permanent saves and you could revisit any of them in any mission, and you could save the game manually at any point. Most missions also limited you to a single squad, and killed squad members would ''not'' be replaced mid-mission. ''Call of Duty 2'' is the game that established the ''Call of Duty'' gameplay style (regenerating health, 2 weapon slots, quick grenades, mission select, console-style single checkpoint saving, etc.) which has remained largely consistent throughout the rest of the series.
** Until Call of Duty 3, there were no cut-scenes in-between levels, only slide show briefings and journal entries, with the occasional bit of stock footage from the Military Channel. Speaking of which, the journal entries of some characters gave the heroic mimes of the game more characterization than future protagonists. For example, Private [[OnlyOneName Martin]] in the first game had ''much'' more characterization than Derek "Frost" Westbrook from ''Modern Warfare 3'', a game that came out 9 years after the original, because of it.
* EasyLogistics: Oh so averted by the Russians. As in every game in the series, the Russians are woefully undersupplied. The men fighting in the first game are clearly not well trained and are very afraid. Each man is given a gun or 5 bullets for one, then told to attack and not give a step or get shot. It's a bloodbath.
* ElitesAreMoreGlamorous: A series staple starting with the 101st airborne unit from Call of Duty 1.
* EmergencyWeapon: ''Call of Duty'' 1 and 2 allow you to club enemies with the butt of your rifle. ''World at War'', in addition to keeping ''[=CoD4=]'''s [[QuickMelee one-button knife]], added one step to this with the bayonet attachment, extending your melee attack reach when holding a rifle equipped with it. Banzai chargers are a regular source for these in singleplayer, although they're always Arisaka bolt action rifles.
* EnemyChatter: There's a lot of shouting from both sides, though the enemy's is in [[BilingualBonus their own language]].
* TheEnemyWeaponsAreBetter: Played straight with the German weapons, many of which are better, or at least easier to use. Generally averted with the Japanese weapons in "World At War", as the American weapons are easier to aim with or focuses on MoreDakka. And played straight if you use them largely because as you kill enemy soldiers you probably won't have to worry about stocking up on ammo, unless you simply wait for your allies to get killed and take their weapons.
* EveryCarIsAPinto: Enforced in that any vehicle that ''isn't'' a car except the tanker trucks can not explode.
* TheFaceless: Notably averted in ''Finest Hour'', in which all of the playable characters are depicted visually and even have spoken dialogue in cutscenes. ''Call of Duty 2'' had a lesser aversion, where every player character's face was shown in the mission-select screen.
* FirstPersonShooter
* FissionMailed: In most of the games, if your characters is stunned by an explosion, or the area is being bombarded by an artillery barrage, the action will [[InterfaceScrew slow down and blur]], sometimes playing the same sound heard when the player dies, which can lead to confusion and possibly a real death if the player is in the open.
* FlamethrowerBackfire: ''World At War'': Nazis with flamethrowers explode when their tank is shot; indeed, Reznov advises you to take advantage of this. In the Pacific, flamethrower Marines will explode in scripted events but the player is immune to this weakness.
* FleetingDemographicRule: ''Call of Duty'' ended with the Soviets storming the Reichstag and planting the flag on top. [[spoiler: Guess how ''World at War'' ends.]]
** [[spoiler: They end differently. COD 1 had someone else wave a flag while you watched. COD 5 had you surviving a bullet wound and get a rousing speech... and then the last cutscene shows historical black-and-white footage of the ''actual'' flag.]]
* FriendlyFireproof: Inside multiplayer, unless you play on Hardcore mode. Averted for single-player, and causing too much friendly fire will grant you a NonstandardGameOver.
** You are not immune to your own fire ever, though. Watch out where you toss that grenade.
* GameplayAllyImmortality: only for major characters, whereas NewMeat dies just as easily as the protagonist.
** ''Finest Hour'' averts this, where major characters are just as vulnerable as you are - however, the game also adds medkits that you can carry around and use on them if necessary.
** Also occasionally averted for those major characters in the original, for example Private Elder from the American campaign can die in combat with no consequence at any point after the driving sequence.
* GangUpOnTheHuman: Usually averted, since you almost always have allies with you, which provide another target for the enemies to shoot at as well. Played straight when you take too long to take out a machine gunner if attempting to snipe them. They will usually notice you aiming at them within a couple of seconds and proceed to start firing at you if you miss, or take too long to fire.
* GrenadeSpam: Be prepared to see upwards of three grenades tossed at you at any one time. Even worse in the original game, as there is no HUD indicator for nearby grenades.
* {{Griefer}}: Hardcore is filled with team-killers, to the point it's often become standard practice to kill each other after a round is over for fun.
* HarderThanHard: [[WildMassGuessing One wonders]] if the developers are attempting to [[JustifiedTrope justify]] the IdiosyncraticDifficultyLevels by making the Veteran mode give you [[GallowsHumor Post-Traumatic Stress Disorder]].
** Best described by IW themselves.
--->'''Veteran Mode:''' ''You will not survive.''
* HaveANiceDeath: Excluding ''World at War'', dying in any of the games under normal circumstances shows you some form of quotation relating to war.
* HealThyself: Medkits in the first game and expansion, variously healing 10, 25, or 50 hit points. ''Finest Hour'' had a similar system; normal medkits heal 25 health on contact, while larger medkits heal 50 and can be carried 4 at a time to use when necessary.
* HeroicMime: Applicable in all games, though ''Finest Hour'' and ''3'' avert this trope.
** {{Lampshade|Hanging}}d in the mission on the ''Tirpitz'' in the first game, where Price specifically tells you to let him do the talking, "unless your German's improved".
* HeWhoMustNotBeSeen: Averted in ''Call of Duty 2''; if you go to Mission Select, you can see the faces of all the characters you play, notably in a photographic format.
** You can see a glimpse of Miller in the intro of ''World at War'', though the "M.I.A." notice on his dossier manages to cover his eyes. He also shows up in the PS2 port, which is otherwise notorious for being very low quality.
** Averted in ''Black Ops'' three times. The first time is with Alex Mason, the game's main character; before actual gameplay even starts, you can see his face on the monitors in the interrogation room. The second time is with Hudson, who you've already seen multiple times before you play as him in a few missions. [[spoiler:The third example is when you play as Reznov in a flashback. Dimitri Petrenko, the Russian player character in ''World At War'', is in your squad.]]
* HitScan: All bullets. This leads to SniperPistol. [[ShortRangeShotgun The shotguns are very exempt from this]].
* HoldTheLine: Played straight in defending Point Du Hoc and Hill 400 in ''Call of Duty 2''. The game even had a level actually called "Holding the Line", which was all about this.
** ''Call of Duty 1'' had British paratrooopers defending Pegasus Bridge from a German counterattack.
** The last segments of Hard Landing (you can use a wall-mounted MG, your personal weapons or even a captured Triple 25 anti-aircraft artillery three-barreled gun) and Breaking Point in ''World At War'' are also examples.
** ''Black Ops'' has the defense of Khe Sanh in Vietnam. A ''tide'' of NVA troops rush at you throughout the mission.
** The ''ModernWarfare'' series has several. The end of the Chernobyl mission involves you holding off waves of Russian infantry until the extraction helicopter arrived. ''ModernWarfare 2'' had the Rangers defending Raptor while TF141 had to protect a DSM while it downloaded critical data.
* {{Homage}}: To ''EnemyAtTheGates'' in ''World At War''. Think about it. Both scenes start with Nazis and tanks passing by a fountain, a Nazi randomly shooting the dead bodies, someone faking death and moving, being assisted by a sniper, having to take out henchmen from cover while using the sound of bombers overhead to mask your rifle shots' report, then killing an officer who tries to flee. Oh, and the Nazi who begins to nervously approach you. Also, the opening scene in Finest Hour bears a striking resemblance to Vasili's entry into Stalingrad, right down to "The first man in line gets the rifle, the second, ammunition!"
** Two at the beginning of World at War: one of the captives is [[GomerPyleUSMC Private]] [[FullMetalJacket Pyle,]] and a little into the first mission a private will be grabbed by a burning Japanese soldier and [[Series/TwentyFour Jack Bauer]] will yell for you to rescue him. The private's name? [[SavingPrivateRyan Ryan.]]
** The beginning of the first game's Stalingrad campaign (the first mission and the beginning of the second one) is also lifted straight from ''EnemyAtTheGates'', rampant historical inaccuracy and all.
** The first game and ''United Offensive'''s American campaigns take copious amounts of inspiration from ''BandOfBrothers'', most notably by having a mission set at Brecourt Manor in the first game and taking the Foy single player mission and multiplayer map in ''United Offensive'' straight from the show. The Italian segment of the British campaign in ''United Offensive'' also has been noted for its similarities to ''Literature/TheGunsOfNavarone''.
** One of ''Black Ops''' Laos levels starts with a scene where [[Film/TheDeerHunter two POWs use a game of Russian roulette to escape their captors.]]
*** Immediately after, you begin re-enacting ''Film/{{Rambo}}'' - and right before that, the Russian Operator's presence commanding the Viet Cong is reminiscent of ''RamboFirstBloodPartII''.
*** The level "Crash Site" ends with [[spoiler: a shot mirroring the finale of ''ModernWarfare.'' Your squad is severely wounded, and you are flat on your back in the dazed state. You pull an M1911 as the BigBad approaches, but this time he kicks it away and you and your CO are captured.]]
**** [[spoiler: If you do pull the trigger before he gets to you, you realize the gun is out of ammo, not unlike that fellow who survived the helo crash in ModernWarfare 2.]]
** Black Ops cribs a good amount of plot from [[spoiler: ''TheManchurianCandidate'']]
** [[spoiler:Dimitri]]'s death is reminiscent of the poor bastard in ''Film/TheRock'', and NOVA-6 is very similar to the film's VX.
** The assault on [[spoiler:the final level]] brings up a very ''Film/JamesBond''-esque theme.
* HoYay: [[invoked]] Dimitri and Reznov. Well, not really, but that doesn't stop [[http://www.youtube.com/watch?v=uH7k9KIrfE4&NR=1&feature=fvwp this video]] from joking that there is.
* HyperspaceArsenal: Averted, as you can [[LimitedLoadout only carry up to two weapons]] (three in the original game and its expansion), though ''inverted'' somewhat in that a pistol with a few spare mags is treated as being the same effective size as a rocket launcher in any game later than ''United Offensive''. In single-player this can be two primary weapons, a primary and a pistol, or two pistols; in multiplayer it's a primary and a pistol unless you're using the Overkill perk to be able to carry two primary weapons, though there's nothing stopping you from dropping your pistol for someone else's gun. In both modes, though, you have the knife.
** This is played straight in ''ModernWarfare 2'' multiplayer with the perk One-Man Army, that replaces your secondary weapon with a backpack that lets you switch out your current class for another you have set up, also replenishing grenades and ammo without having to die first. Add to that you have a total of five custom classes (and five pre-built ones) and that backpack must be getting pretty heavy.
*** Not to mention that any of those classes could [[InfiniteSupplies also have One Man Army...]]
*** In the Campaign mode of ''ModernWarfare 2'', this is averted, as you can actually see where all of the weapons are on the other {{NPC}}s. Further averted in multiplayer for that game and ''Black Ops'', where the Overkill perk was removed.
* ICallItVera: [[http://3dvision-blog.com/wp-content/uploads/2010/11/call-of-duty-black-ops-box.jpg The cover art]] for ''Black Ops'' has Alex Mason holding a pistol with the name "Sally" etched into it.
** Mustang and Sally in NaziZombies... and they spit out grenades. In full-auto.
* IdiosyncraticDifficultyLevels: Greenhorn/Recruit, Regular, Hardened, and Veteran.
* IdenticalGrandson: The Captain Price of ''Modern Warfare'' looks just like Captain Price in ''Call of Duty'' and ''Call of Duty 2'', right down to the [[PornStache righteous mustache]].
** It's even implied that Price is [[ReallySevenHundredYearsOld the same man in every game he appears in]].
** Also, Sgt. Reznov in ''World at War''/''Black Ops'' is an ancestor of Zakhaev from ''ModernWarfare'', to the point that he uses a modified version of Zakhaev's model in-game. Zakhaev's own son even has the same first name as Reznov (though by way of a RetCon).
** Also, Foley, who was present in the first game, makes a reappearance in ''ModernWarfare 2''. However, the first Foley was white and a Captain while the ''ModernWarfare 2'' version is black and a Sergeant. Similarly, there's an unseen Major Sheppard (spelled that way before you correct it) in the first game and a General Shepherd in ''Modern Warfare 2''. Ramirez turned up in ''United Offensive'' as a Sergeant.
* InsurmountableWaistHeightFence: The series has quite a few unclimbable chest-high walls. Which is odd, seeing as there are also climbable ''head''-high walls.
* InTheBack: You get more points for knifing enemies in multiplayer in the back. People using riot shields in ''Modern Warfare 2'' and ''3'' are typically only vulnerable from this direction, as well.
* ISurrenderSuckers: In "World At War" some of the Japanese troops at certain points will seemingly do this, only to then do a [[TakingYouWithMe suicide attack]] on the characters attempting to shake them down for intel.
* ItsUpToYou: Many, many examples. Let's just say that unless the player moves their ass and gets across the room, the enemies will usually keep spawning at the far end indefinitely. Though, to be fair the {{NPC}}s, especially the unkillable ones, sometimes act useful to the plot, too. Fortunately, in some case, it only ''looks'' infinite... particularly if you're just picking a really suboptimal approach to the objective.
** It may be [[LampshadeHanging lampshaded]] in ''World at War'', where Sergeant Reznov tells you that "As long as you live, the heart of this army will never be broken."
** ''World at War'' has what is perhaps the silliest example: defending againt a Japanese counterattack on Pelielu, there are two anti-air cannons and two fixed machine gun that the player can use against them. [=NPC=] allies are for some reason unable to make use of the additional firepower.
* ItWillNeverCatchOn: When ''Call of Duty 2'' first came out, the RegeneratingHealth system was criticized, with critics claiming that it made the game too easy. Oh, how wrong they were...
* JustPlaneWrong: In ''World At War's'' Stalingrad stage, huge numbers of four-engined Focke-Wulf Fw 200 Condors are seen flying overhead. Only 272 were built in total, with hardly any of these being present at Stalingrad, certainly not in the numbers shown. Only nine Condors were shot down over Stalingrad.
** The PBY Catalina the player controls the guns in for one mission has both Oerlikon 20mm cannons and Browning M1919 machine guns in the bow turret. Real Catalinas in the Pacific were sometimes armed with the cannons, but the Brownings would have to be removed to make room for them.
* KilledMidSentence: In the ''World at War'' mission "Little Resistance", the landing craft the player character is in gets caught on something. An {{NPC}} then shouts "It's the coral! We're stuck on the cor--" *[[PinkMist Cue]] [[BoomHeadshot headshot]]*
** Poor, poor [[RedShirt Private Koopman]].
** Also in ''Black Ops'':
-->'''[[spoiler:Clarke:]]''' "Ah, yes, the numbers! [[HisNameIs They're the key to-]]"*BOOM*
* KillEmAll: None of your allies in ''Call of Duty 2: Big Red One'' survive except [[spoiler: Sgt. Kelly], Cpl. Smith and Cpt. Delaney]].
** [[spoiler: In ''Black Ops'', both Woods and Bowman die near the end of the game. And, well... Reznov was DeadAllAlong. Hudson survives, though, as do Mason and Weaver.]]
** [[spoiler: It is, however, stated in an email that Woods was actually taken prisoner and sent to Hanoi's prison camp, where a rescue force was sent to help him.]]
** [[spoiler: Woods is alive in Black Ops 2, at the ripe old age of 95. He serves as the game's segue between the 1980s missions and the futuristic 2025 missions.]]
** [[spoiler: Even Reznov seems to be alive as well in Black Ops 2, but it is left open as to whether its actually him or simply Mason hallucinating again.]]
* KillItWithFire: The flamethrowers in ''United Offensive'' and ''World at War'', used by both Allies and Axis soldiers. ''[=WaW=]'' also has a flamethrower mounted in a tank, and refreshing Molotov cocktails. ''Black Ops'' has a flamethrower attachment for assault rifles.
* LargeHam: Sergeant Reznov in ''World at War'' starting with the level ''Their Land, Their Blood''. He arguably manages to out-ham Commissar Markhov, who has NoIndoorVoice and speaks half his lines ''through a megaphone''.
** Reznov hasn't lost his touch in Black Ops.
---> ''Reznov'': "Never lose faith, friends... NEVER! MONTHS of planning, Mason. We will NOT pause. We will NOT falter. We will be FREE - OR DIE TRYING!"
** This guy could've written a best-selling book: "How to Escape From Prison in 8 Simple Steps." See SpySpeak below.
** In Black Ops, [[spoiler: hearing Reznov talk about Demitri's death is downright ''depressing.'' Instead of his hilarious Hamvoice, he talks in a very downcast and softspoken way about how Demitri should have died storming Berlin, instead of dying like a test animal.]]
** The multiplayer announcer for the German side in ''World at War'' gives Reznov a good run for the money in terms of ham.
* LeftTheBackgroundMusicOn: In a scene in the ''World at War'' mission "Eviction", "Dies Irae" playing in the background. If you follow the sound of the music, you will eventually find a running gramophone. Destroying it will stop the music.
* LimitedLoadout: As noted above, in almost all games in the series the player is restricted to two main guns plus some accessories like grenades and whatever other shiny things you've brought along, [[GunAccessories usually attached to one or both of your guns.]]
* LimitedSpecialCollectorsUltimateEdition: Special editions existed for ''Call of Duty 2,'' ''ModernWarfare 2'' and again for ''Black Ops''.
* MadScientist: Richtofen in Nazi Zombies. He invented the Wunderwaffen DG-2, and he's certainly a madman, what with the screaming in orgasmic joy of blowing off body parts. Also, may or may not be Edward, a scientist who murdered his business partner and said partner's daughter.
* MagikarpPower: The M1 Garand rifle in ''World at War'' multiplayer. Compared to the other semi-automatic rifles in multiplayer, it requires one less shot to kill a basic player and reloads quickly when empty... at the cost of a smaller magazine, much lower maximum fire-rate and heavy recoil which generally makes other basic semi-automatic rifles much more appealing to use. Thus the Garand's real benefit lies in unlocking its scope attachment at 100 kills with the weapon, which when equipped causes it to kill enemies with one shot in the head like other scoped sniper rifles. Combined with the Stopping Power perk, the scoped Garand will also kill with any shot to the chest or head and has the additional benefit of a much higher fire-rate, larger magazine and starting ammo reserve than the other bolt-action scoped sniper rifles to make it a potentially truly terrifying sniper rifle.
* MasterOfUnlocking: Typically, only the ranking officer in a squad has had the years of training required to operate a door. Except ''Call of Duty 1'', where the player can open some doors when required, and ''Call of Duty 2'', where said ranking officer tends to make his second-in-command open doors instead.
* MilitaryAlphabet: Military game. Natch.
* MultiPlatform: Oddly enough, the side story games were multi-platform before the main series.
* MultipleEndings: Sort of.
** In the final mission of World at War's the American Campaign: [[spoiler: Roebuck and Polonsky get themselves into hand-to-hand combat with two Japanese soldiers that pull an ISurrenderSuckers. The player is given the option to save Roebuck or Polonsky. After the final battle, the character you picked to survive will go up to the body of the other, remove his dogtags, and hand them to you, as Roebuck gives a final narration.]]
** Before the final mission in ''World at War,'' Reznov will read a passage from Chernov's diary. If the player went and slaughtered helpless Germans during the Soviet Campaign, the passages will be critical, if the player spared them, the passages will praise the player. If the player did a mixture of both, the passages will paint the character as a moral question mark.
* MoreDakka: Aside from all the vehicle-mounted and fixed machine guns, autocannons and grenade launchers in the games, the minigun in ''Black Ops''.
* NamesToRunAwayFromReallyFast: Makarov in [=MW2=] is named after a gun.
** Note: the gun in question was named after the designer, as are many Russian/Soviet weapons. Could simply be FamousNamedForeigner.
* {{Nerf}}: For better or worse, the (in)famous [=MP40=] is noticeably weaker on the PC version of ''World at War'' compared to the console version, dealing the same damage as the Thompson (instead of significantly more), while retaining its lower rate of fire). Why they did this in the PC version only instead of implementing it in the console version as well via a patch is anyone's guess.
* NewMeat: ''[=CoD=] 2'' plays this trope even straighter than ''MW'' - your character for the tutorial level is a newly drafted Russian Infantryman ''literally'' fresh off the truck, who's never fired a rifle in his life. The first level involves [[ShootingGallery shooting bottles and plates on a nearby fence]], throwing potatoes ("Grenades are more valuable than you'll ever be!") into a destroyed building for grenade practice, and [[ThisIsNotADrill destroying a German armored car that entered the area]].
** Partially averted in ''ModernWarfare 2''. While there is a tutorial level at the beginning, your character goes through the tutorial to show a group of locals how to fight, not so your character himself learns.
* NightOfTheLivingMooks: The unlockable Nazi Zombies bonus level after you beat ''World at War'', where you fight, [[ExactlyWhatItSaysOnTheTin well...]]
* [[NinjaPirateZombieRobot Nazi Zombies]]
** ''Japanese'' Zombies!
*** Zombie Dogs!!
**** ''[[IncendiaryExponent Flaming]]'' [[MadeOfExplodium EXPLODING]] [[RunningGag Zombie Dogs!!!]]
* NiceJobFixingItVillain: Black Ops: [[spoiler: The SAS raid on the Nova 6 ship unwittingly saves Reznov from being exposed to the chemical weapon.]]
** Of course, [[spoiler: they aren't so much villains as just the people who happen to be fighting against you, particularly in comparison to the two other factions involved.]]
* NoAnimalsWereHarmed: "No cows were harmed in the making of this game" at the end of the first two games, due to all the dead cattle that popped up everywhere, particularly in the first game's American campaign.
* NoCampaignForTheWicked: Unless you count campaigns for the Stalinist Soviets who brutally kill their enemies despite any notions of surrendering.
* NominalImportance: Every friendly soldier has a name. Members of the RedshirtArmy have randomly-selected ones. [[RedShirtArmy Don't bother learning them.]]
** The prisoners in Vorkuta don't even have names, only serial numbers.
* NonCombatEXP: In the multiplayer, players have levels. They must gain XP to level up, which allows them access to new weapons. You mainly get XP through kills, but the game liberally dishes out XP for getting kills in special ways, such as revenge kills ("Payback!") or killing an enemy immediately after they killed a teammate ("Avenged!"). You can also get lots of bonus XP for certain achievements, like getting a certain number of headshots with a weapon, or using a perk a certain number of times. In objective-based gamemodes you also will get XP for capturing objectives.
* NonstandardGameOver: When you get blown up by a grenade ("Watch for the grenade danger indicator"), chewed up by a dog ("Press (melee key) to fight off the dog") or accidentally shoot one of your teammates ("You are a traitor to the motherland!" and/or "Friendly fire will not be tolerated!").
** ''Black Ops'' also gives you a new one if you are [[spoiler: exposed to Nova 6]], and one if you failed basic safety and [[TooDumbToLive ran between the propellers of a cargo plane's engines]].
* NostalgiaLevel: The Reichstag was the final level in the 1st Call of Duty. It appears as the final level of the 5th, but this time it's a LOT harder.
* NoSwastikas: Averted.
** Played straight in a few instances in ''World at War''. One example is the multiplayer map "Breach", which features the Brandenburg Gate adorned with red flags with white circles in the middle, and, you guessed it, Iron Crosses. Particularly interesting when you consider the Nazi Zombies map included in the same map pack has several ''neon blue'' swastikas.
* NoticeThis: Important stuff is often glowing. In the first game, so did medical items.
* ObligatoryWarCrimeScene: ''World at War'' more went for scene'''s'''. Prisoners don't exactly get taken.
* [[OminousLatinChanting Ominous German Chanting]]: Going into the German Parliament building causes this. First you start hearing German propaganda, then you hearing ghostly moans, then you can finally hear the running music that was drowned out by combat, and, finally, you hear the chanting. The whole level is designed to leave a huge impact whether it's fear, awe, or elation.
* OneBulletClips: Enforced - one of the most common tips repeated to you is to reload early and often, and if you fail to heed that advice your reloads take longer.
* OneManArmy: Averted... [[ArtificialStupidity in theory]].
** Played straighter in Black Ops, where [[spoiler: any section where Mason's teamed up with Reznov alone is actually him single-handedly going on a massacre]]
* OptionalStealth: In these games, the other characters hide against walls before entering rooms, and lots of the players do this. It's actually easier just to stand in the middle of the doorway and shoot as while you're trying to navigate around the edge of doors (massive pain), your enemies can get shots in. It's also far too hard to make your player drop to ground, but there is no additional penalty or chance of injury if you just stand up in the middle of the place. Being un-stealthy is, if anything, advantageous.
** The ''ModernWarfare'' games have a few missions where your superior will encourage you to sneak past enemies or at least use silenced weapons on them. It's not required, though, and while you'll get mobbed it is possible to fight your way out. Said superior will chew you out, though. Plus, the missions "All Ghillied Up" and "Cliffhanger" have achievements for not being spotted.
* PersonalSpaceInvader: Banzai chargers in ''World at War''. (Note: It ''is'' actually possible for the player to embody this trope, whether using the knife or a rifle bayonet.)
** There are also a few scripted moments in ''Black Ops'', and of course, there are always those [[GoddamnBats goddamn dogs]]. One such encounter is a MythologyGag to a similar moment in ''Call of Duty 3,'' where you deprive a mook of the pins to his grenades- [[PineappleSurprise while they're still on his belt.]]
* ParachuteInATree: In the first game.
* PlayingPossum: Some enemies, when critically wounded and grounded, keep shooting you with their handguns. If this happens in the single-player campaign, you should be able to scoop up their pistol upon their death -- while this is ''exactly'' how the Last Stand perk works in multiplayer.
** In ''World at War'', Japanese enemies can and will lie in wait in the grass, nearly invisible until they're on top of you. Liberal application of flamethrowers and shooting at misshapen lumps evens the odds. What's more, in some instances Japanese units will literally play dead until you're right on top of them.
* PressXToNotDie: ''World at War'' to take out Banzai chargers if they do the same.
** ''Call of Duty 3'' also has several of these at predetermined places.
** ''Black Ops'' also has a few scripted events like this.
* RagTagBunchOfMisfits: The majority of the playable characters and the squads they are in. Seems to be lessened slightly in the Modern games, as the groups tend to be more well trained and cold, though the Soldiers [[RedShirtArmy (the important ones, anyway) ]] do still have a lot of loyalty and respect for each other. Probably the epitome being Soap, who has a thicker frame and rocks a mohawk, and Captain Price, who has an amazing mustache that stands for the ''freedom'' of ''the world'', and the two are best friends.
* RatedMForManly: You get to shoot/blow up countless mooks and bosses, and on top of that, your team consists of beefed-up macho Navy SEAL elites and a tough-as-nails Marine in Black Ops 2. Need I say more?
* RayGun: A surprise appearance by name as one of the best weapons in World at War's Nazi Zombies mode.
** It's also possible to find it as an Easter Egg in the campaign.
* RealityIsUnrealistic: Remember Pavlov's House in the first game? Seems silly, that one house holding out against a whole German army complete with tanks...Except that it really happened. And a realistic version of the mission would be three ''months'' long.
* RealIsBrown: Every game (except parts of "Modern Warfare 2", mostly in Brazil, and most Russian missions in the early games, which are covered in snow) has a basic color palette of brown. World at War, however, has a lot of gray as if everything is an old video tape of the war.
* RedshirtArmy: Any ally you see who is not important to plot, unless you go out of your way to protect them, is going to die.
* RedsWithRockets
* RegeneratingHealth: ''Call of Duty 2'' and thereafter.
** Possibly [[LampshadeHanging lampshaded]] in ''World at War'', where Reznov says he has seen you cheat death over and over again.
* ReportingNames
* ReverseGrip: The only way a knife may be used in ''World at War'', unless it's [[BayonetYa attached to a gun]].
** If you die during the American Marine campaign by a Banzai charger, you'll see yourself holding your knife in a normal grip. Since succeeding to [[PressXToNotDie press the knife button]] before they stab you has your character push away their bayonet and stab the charger in the neck in a ReverseGrip, it can be interpreted that your character attempting to draw the knife in a normal grip to fight the charger was an incorrect action that cost him his life.
* RecurringLocation: Berlin and Stalingrad in particular. Normandy in general is pretty common as well, though no one location within appears in more than one game.
* RousingSpeech: "For Mother Russia, comrades!"
** "For the Soviet Union, and for your Glorious Motherland! Get ready!!!"
* SequelEscalation: ''United Offensive'' was the original game turned up to eleven. Gun turret sequence where you shoot a vaguely preposterous amount of tanks? Right, let's have a gun turret sequence where you shoot down half the Luftwaffe! Pavlov's House? Now it's a bigger house with even nastier attack waves! Big dramatic ending? Let's defend a railyard that's constantly being attacked by tanks, Stukas, and Germans who are apparently breeding frantically inside the signal box!
** And unlike ''ModernWarfare 2'', everyone agreed that it was '''awesome'''. Sure, the battles portrayed in ''United Offensive'' aren't as famous as the ones in the original, but the cool factor more than makes up for it.
* SergeantRock: Sgts. Sullivan, Roebuck, and Reznov in ''World At War'', though Reznov sometimes shows some [[TheNeidermeyer Neidermeyer-y]] tendencies toward the unfortunate Pvt. Chernov. [[spoiler:This is until the poor private gets fried by a German flamethrower, after which Reznov seems to recant his negative opinion of Chernov's journal]].
* ShootingGallery: The opening levels of ''2'' and ''4''.
* ShortRangeShotgun: Shotguns have a cutoff point after which they cannot damage anyone at all. The cutoff point is like, seven paces.
* ShoutOut: In ''Call of Duty 2'', many of the actors who worked on ''BandOfBrothers'' had major voice acting roles in the game.
** The mission "Vendetta" in ''World At War'' is full of shout-outs to the movie ''EnemyAtTheGates'', from the fountain scene at the beginning to the entire "Soviet sniper tracking down a wicked Nazi officer"-theme.
*** The first Call of Duty's Stalingrad mission basically ''was'' ''EnemyAtTheGates''.
*** A couple of grunts named Zaitsev and Danilov accompany you at the start of the train station mission.
** You get to see Privates [[FullMetalJacket Pyle]] and [[SavingPrivateRyan Ryan]]. Guess what happens to the first and what [[Series/TwentyFour Jack Bauer]] wants you to do to the second.
** The tank mission in ''World At War'' has a shout-out to ''ModernWarfare'', during the loading cut-scene you can hear the woman's voice who warns people about the nuclear blast in ''ModernWarfare'' playing softly in the background.
** In Finest Hour, Sgt. Starkey, voiced by [[Music/{{ACDC}} Brian Johnson]], has a few lines that shout out to lines from his songs.
** The scene towards the end of ''Black Ops'', where [[spoiler:Steiner is in a chair and gets shot by [=Reznov/Mason=]]] looks oddly close to the climax of ''[[spoiler:Film/FightClub]]'', which makes sense, as they share a critical plot point.
** In ''Black Ops'', the name of the CIA analyst in all of the intel files is Ryan Jackson - an inversion of Literature/JackRyan.
** Also in ''Black Ops'''s intel files, there's a reference to [[Film/ApocalypseNow a voyage up the Nung river]] to eliminate a rogue SF colonel. The achievement for that level is "Never get off the boat".
** According to ''United Offensive'' privates [[TheyMightBeGiants Linnell, Flansburgh]], [[VideoGame/{{Half-Life}} Gordon, and Freeman]] fought in the Battle of the Bulge.
** A couple of missions in ''World at War'' has the player using [[Film/SavingPrivateRyan mortar shells]] as grenades.
* SillinessSwitch:
** NaziZombies.
** Goes farther with ''Shi no Numa''. The four soldiers' backgrounds are {{Sociopathic Soldier}}s (PlayedForLaughs), and apparently, there is a zombie war going on.
** In''Black Ops'' zombie mode, you can play as Presidents Kennedy and Nixon, Defense Secretary Robert [=McNamara=], and Fidel Castro in one of the most wildly implausible but hilarious ZombieApocalypse scenarios ever.
** Co-op campaign in ''World at War'' has some Death Cards that are also pretty silly - the Joker card arms you with nothing but a knife and rocks, Ace of Spades makes enemies look like the aforementioned Nazi Zombies, Six of Clubs gives you paintball guns, and Eight of Hearts causes enemies shot in the head to ''explode''.
* SniperPistol:
** Pistols are HitScan and aiming down your sights makes every shot fire directly at where the sights are aiming at. This can let them go a very long way in good hands.
** In ''World at War'' the Gunslinger achievement is attained by doing this to kill General Amsel. Note that Amsel is at least TWO BLOCKS AWAY.
* SniperScopeSway: Very minor amount in the original (which works pretty similar to the ACOG from the later ''Modern Warfare'' series, though with more zoom). The games after the original have much more noticeable scope sway, and let you hold your breath to steady your aim for a few seconds, after which the sway will be even worse until you get your breath back. You can also use perks to extend how long you can hold your breath in multiplayer. The same is true of the thermal scope, while the ACOG scope has a lower zoom level and less sway, but you can't hold your breath.
* SnipingMission: "Vendetta" in ''World at War''.
* SociopathicSoldier: Every character in the Shi No Numa and Der Riese maps. The American one's voiced by Creator/SteveBlum.
** Sergeant Reznov likes killing Germans a little... ''too'' much.
---> '''Reznov:''' ''(if the player stops shooting or moving for more than a second during [[TankGoodness "Blood & Iron"]])'' WE COULD BE [[KillItWithFire BURNING]] GERMANS RIGHT NOW!!
* SpamAttack: The entire series frequently has [[TheComputerIsACheatingBastard the enemies constantly throwing grenades at you]]. It had a slightly more honest instance in ''World at War'' of a Japanese soldier programmed to be standing over a castle's balcony constantly throwing grenades at you until you get close enough for him to worry about you and just shoot at you.
* TheSquad: Too many to count.
* SuicidalOverconfidence: Some Japanese troops in "World At War" will simply attempt to rush you with a banzai charge, especially if they're down to just a few soldiers. Needless to say, this often goes badly for them, unless they catch you from behind. TruthInTelevision however, as some Japanese soldiers did in fact attempt these during the war, and it also didn't go very well for them either.
* SuicideAttack: If you hear Banzai less than 30 times during World at War, then you assuredly put in the wrong disc.
* SuicideIsShameful: The "Last Stand" perk in ''Call of Duty 4'', in which a player is merely knocked down rather than killed when taking fatal damage, gives players the option to kill themselves and immediately respawn rather than wait to bleed out or get shot by an enemy. This is labeled the "Coward's Way Out".
* StoppedNumberingSequels: From ''World at War'' onwards.
* StoryDrivenInvulnerability: The enemy {{mooks}} who kill [[spoiler: Sergeant Sullivan, Private Chernov, and Polonsky or Roebuck]] in ''World at War'' are either invincible till after they deliver the killing blow to the above {{NPC}}s or circumstances simply prevent you from shooting in time.
** In Modern Warfare: the final part of mission "One Shot, One Kill", when you picked up [=MacMillan=] to rush for the heli, the game will enable God Mode for you.
* StrangeMindsThinkAlike: "You look like hammered shit." Considering these quotes {{Book End|s}} one of the hardest missions in ''Black Ops'', it can count as BreakingTheFourthWall too.
* SturgeonsLaw: Between each of the "main" installments, Activision tries to make some quick cash with a game (initially console-exclusive before the series shifted focus to them, now often handheld- or last-gen-exclusive) made by another developer. Quality-wise, this worked well with the first one, ''United Offensive'' (the developer, Gray Matter, was eventually bought by Treyarch). [[FlameWar The rest?]]
* SuddenSequelDeathSyndrome: [[spoiler: In Reznov's flashback mission in ''Black Ops'', Dimitri is revealed to have survived his wounds from the end of ''World At War'' - then he's horribly gassed to death in front of Reznov.]]
* TankGoodness: Any level regarding driving a tank, of which there is at least one in every WWII installment.
* TechnicalPacifist: The closest description of Pvt. Chernov in ''World At War'', who is mostly okay with killing Nazis, but never more than is necessary and absolutely refuses to torture them like Reznov and the player might. He's no coward, and he tends to take point in the formation as well as fight.
* TemptingFate: [[spoiler:Brooklyn]] in ''Call of Duty 2: Big Red One'' in the last level. "I think I might actually make it home from this lousy war!" Cue to mortar shells and one dead body.
* TheStinger: Captain Price's rescue in ''Call of Duty 2'', the Nazi Zombies in ''World at War'', and Zombie Mode in ''Black Ops''.
* UnexplainedRecovery: [[spoiler: World at War's ending saw Dimitri Petrenko taking what seemed to be a lethal pistol shot. Black Ops reveals he recovered just fine, and in 6 months he was back in action kicking Nazi ass. Until he got gassed by his own commander.]]
* UniversalDriversLicense: Parodied in a sequence in ''Call of Duty 2'' where Captain Price tries to teach how his men to drive.
** And when your Scottish comrade complains that the instructions to a German armored car are all written in...German.
** Played straight in ''World at War'''s Blood and Iron mission, where Dmitri drives a tank. Somewhat justified by the fact that the Soviets designed the T-34 to be easy to drive with very little training, so they could get drivers for the tanks as fast as they could make 'em.
** Also played straight in ''Black Ops'', where Mason is capable of driving not only cars, but boats and helicopters as well. ''Black Ops II'' continues this with Section, who is otherwise not shown to have any training in the use of aircraft, taking control of a VTOL-capable fighter jet at the end of one level.
* UnexpectedGameplayChange: In the first game, you control a tank during the liberation of Poland. There's also ''The Tank Squadrons'' in ''Call of Duty 2''; ''Liberators'' in ''Big Red One''; ''Blood & Iron'' and ''Black Cats'' in ''World at War'', and the bomber mission from ''United Offensive''.
** Many segments in the handheld version of ''World At War''.
** "WMD" in Black Ops has you briefly fly a plane and then command a squad on the ground RTS-style before going back to the shooting.
* TheUnfought: [[UsefulNotes/AdolfHitler Hitler]], obviously, though [[ForegoneConclusion he has]] [[DrivenToSuicide an excuse]].
* UrbanWarfare: Many levels.
* VideogameCaringPotential: Mostly in the form of protecting your squadmates, though the later titles also offer the chance to [[MercyKill put dying enemies out of their misery]]. ''World at War'' made this more blatant during the campaign.
** There are Russian, German, and American soldiers who are set on fire during ''Black Ops''. The Russians are set on fire when you [[spoiler:shoot down Soyuz 2]]. One of your squadmates says "Poor bastards", but another one says that they should die because they're helping Nazis. You can shoot the dying men if you want. There are also Americans who are set aflame by a Vietcong with a flamethrower, and Germans who suffer the same fate at the hands of your teammates in "Project Nova". All of these are a potential MercyKill.
** ''Finest Hour'' for PlayStation2 added the ability to heal teammates with medkits if they needed it.
** Keeping your squadmates alive is particularly significant in the first ''Call of Duty'' game, as killed squadmates are ''not'' replaced by fresh respawns, unlike in later games. There are quite a few levels where you only have 1 or 2 squadmates that follow you all the way until they die; keeping them alive through the entire level can be something of a self-imposed challenge.
* VideoGameCrueltyPotential: Mixed with some UnfortunateImplications. In ''World at War'', it can be a little unnerving playing co-op with friends in the Pacific Front missions who aren't shy about saying how much the like killing "the Japs."
** This did not go unnoticed by Matt Stone and Trey Parker, as demonstrated in the WesternAnimation/SouthPark episode "The Ungroundable".
--->'''Cartman:''' "Aw dude, I wish I had a real flamethrower! It works awesome on Japs!"
** If you kill surrendering Germans in "World At War", Chernov's entry of you is much more critical of you.
* VideoGamePerversityPotential: The ability to create your own emblems in ''Black Ops'' resulted in the creation of many penis emblems, along with Swastikas, and even [[BreadEggsBreadedEggs swastikas made of penises]].
* VoiceOfReason: Chernov in World at War. Unfortunately, like in real life, he is of the minority and no one listens to him.
-->'''Chernov:''' This is not war. This is murder.\\
'''Reznov:''' THIS is how you end a war, Chernov.\\
'''Chernov:''' This is madness! Our rockets are tearing the city apart!
* WarIsHell: The feeling which they were going for in ''World at War'', with watching many people being turned to {{Gorn}} in the game, and plenty of [[KickTheDog dog-kickery]] in the Eastern Front.
* WeHaveReserves: Basically happens in any map or campaign that has Russians involved. They may even be the protagonists of it and win, but they'll be dying left and right the way there. This can also happen in game since your RedShirtArmy allies will respawn infinitely and you are not penalized for killing them like you would be in other missions.
* WhatTheHellHero: The mission "Eviction" in ''World at War'' explicitly requires you to finish off wounded German soldiers lying on the ground. Then you must kill a group of unarmed soldiers attempting to surrender while Reznov implores you to show them no mercy. If you don't do that, they get burned to death while Reznov yells at you... for being cruel to animals.
** If you do kill them, though, you get a YouBastard moment before the last mission.
* WhatTheHellPlayer: Shooting your own teammates will give you a NonstandardGameOver, giving you the message "Friendly fire will not be tolerated!"
** And on the Soviet missions, you have a NonstandardGameOver FOR the NonstandardGameOver, where everything fades to black and it declares "You are a traitor to the Motherland!"
** Except in [=CoD1=], where you only get that message if you shoot a ''Commissar''. [[WeHaveReserves You can shoot as many conscripts as you like and nobody cares.]]
** In ''Black Ops'', accidentally shooting your allies will cause them to yell at you, wondering what the hell you are doing or demanding you do a better job at aiming.
--->'''Weaver:''' Your side, YOUR SIDE!!!
** The NonstandardGameOver is only triggered when you accidently kill an important named character, but if you kill at least a few random RedShirts nothing happens.
* UsefulNotes/WorldWarII: The entire main series, with the exception of the ''Modern Warfare'' subseries and ''Black Ops''. [[spoiler: Except for "Project Nova" in the latter game, although it is technically after the war, since the mission takes place in October of 1945.]]
* YouAllLookFamiliar: This is especially prevalent in ''Roads to Victory'', where ''ALL'' of the German soldiers look exactly the same. Ditto (albeit slightly subverted) for ''World at War'', except for, strangely enough, the storming of the Reichstag.
* YouBastard: In World at War, if you mercilessly slaughter soldiers left and right in the Russian campaign, a diary entry written about you by a squadmember will talk about how you are no hero. Play more compassionately, the entry will praise you for having some morals. Do a mix of both, and the diary will simply label you an enigma.
