This is about the game series; if you're looking for ''radioactive fallout'' see TheDeadliestMushroom.

The ''Fallout'' game franchise is set in a post-apocalyptic setting with a twist: the pre-war society never got out of the 1950s setting. The timeline diverged from [[RealLife reality]] shortly after WorldWarII, and society progressed [[{{Zeerust}} much in the way it was envisioned to in that time]], with very heavy AtomPunk / ArtDeco styling, until its nuclear end.

It has been many decades since the winds of the apocalypse blew in over America and took the old world with it, leaving only the Wasteland in its place. The event, known as [[WorldWarIII "The Great War"]], was the culmination of a long and bloody struggle between USA and China [[NoBloodForPhlebotinum over the last oil in the world]]. It came in the form of a [[NukeEm massive global nuclear attack]], which in two hours bathed the Earth in fire and radiation and [[TheEndOfTheWorldAsWeKnowIt ended all human civilization]]. But the [[HumansAreSurvivors human race is stubborn]], and not so easily eradicated, and now small societies are starting to pop up all over the North American mainland, and you, the player, can either [[AWorldHalfFull help them prosper]] or take away their hope, and watch them [[CrapsackWorld wither and die]].

Arguably one of the best examples of how to make a nonlinear RPG ever, the original two ''Fallout'' games are loved by a small but passionate audience across the world, who laud the game's intuitive turn-based action and detailed world building, which takes its atmosphere from TheFifties' pop-culture and WeirdScience stories from {{Pulp Magazine}}s. The biggest draw is the way the games - particularly ''Fallout 2'' - allow the player to do pretty much whatever they want.

Character creation is very flexible, letting the player specify their age, race, sex, physical and mental statistics, known skills, and special talents. The player is then dumped into a post-apocalyptic wasteland with a distant end goal, no clear means of how to reach it, and a map that gives directions only as far as the nearest settlement.

It quickly becomes clear that ''Fallout'' is very flexible when it comes to completing goals. For example, upon entering a crime-ridden area, the player can help the sheriff to take down the crooks, help the crooks take over the town, or TakeAThirdOption and [[OmnicidalNeutral mindlessly slaughter every living thing in sight]] (Hey, at least there's no more crime! [[{{Metaphorgotten}} Well, except for that guy who killed everyone...]]). A KarmaMeter tracks the player's behavior, and affects the reaction of other {{NPC}}s; if you're too good then criminals won't trust you with their missions, but being too evil means the same for law-abiding folks. If you ever gain [[VideoGameCrueltyPunishment "child killer" status]] you'll be ostracized by almost everyone. [[EvenEvilHasStandards Even other outlaws]].

''Fallout 2'' takes this even further, with the player able to gain all kinds of different statuses. They can be deputized into the police force, become a porn star, join the Slavers and sell captured tribespeople (or their own NPC friends!), join "The Brotherhood of Steel," go grave robbing, or become made men in the post-apocalyptic [[TheMafia Mafia]]. They can even choose to play with an Intelligence score of 1, which makes them barely smart enough to speak, and completely changes the way the game plays.

Sadly, the multitude of options made the sequel incredibly buggy and virtually unplayable without patches (included in today's jewel case versions, so you have no excuse not to play it). Still, despite isometric 2D graphics that look distinctly crude by today's standards, the ''Fallout'' games continue to appeal to thousands worldwide because of their incredible depth.

The original ''Fallout'' games were followed by a pair of spin-offs. The PC-based ''Fallout Tactics'' was a TacticalRPG which focused on squad-based tactical combat. ''Fallout: Brotherhood of Steel'' for the {{Playstation 2}} and {{Xbox}} was a 3D, above-viewed HackAndSlash that challenged the player to wipe up the wasteland as a member of one of the clans from the original games. They both received variable reviews, although ''Fallout Tactics'' has built up a cult following, ''Brotherhood of Steel'' never gained all that many enthusiasts.

The developer, Creator/{{Black Isle|Studios}}, had nearly completed a third game in the ''Fallout'' series, code-named "Van Buren", when parent company Creator/InterplayEntertainment went bankrupt and shut them down. After spending several years as {{Vaporware}}, Interplay sold the rights to the series to Creator/{{Bethesda}}, best known for ''Franchise/TheElderScrolls'', to save themselves from bankruptcy.

Bethesda chose to start development of ''Fallout 3'' from scratch; their game was released October 2008, and is a fully-three-dimensional game with light {{FPS}} elements. It follows a Vault Dweller from [[UndergroundCity Vault 101]] as he or she searches for a lost [[Creator/LiamNeeson father]]. The FPS elements were [[TropesAreNotBad integrated well]] into the experience.

On April 20, 2009, Bethesda Softworks [[http://kotaku.com/5219584/new-fallout-announced announced]] ''Fallout: New Vegas'', with Obsidian Entertainment as the developers. The game came out on October 19th, 2010 in North America and October 22nd in Europe (the days the bombs fell) on the PC, {{Xbox 360}} and [=PS3=]. Somewhat ironically, Obsidian is run by Black Isle refugees, the developers of the first two ''Fallout'' titles, and several Obsidian employees worked on Black Isle's original Van Buren project. Fan reaction is perhaps best described as "a tiny spark of hope shining through lots and lots of cynicism."

List of Fallout titles (in chronological order):[[index]]
* '''''VideoGame/{{Fallout 1}}''''': The original game. Technically titled ''[[ShortTitleLongElaborateSubtitle Fallout: A Post-Nuclear Role Playing Game]]''.
* '''''VideoGame/FalloutTacticsBrotherhoodOfSteel''''': A linear spinoff developed by 14 Degrees East, featuring a GenreShift to squad-based tactics a la ''JaggedAlliance''. Received good reviews, and is generally regarded as decent, but was poorly advertised and isn't as well known as the main games in the series. Semi-canon, with BroadStrokes.
* '''''VideoGame/FalloutBrotherhoodOfSteel''''': Another linear spinoff, this one developed for the PS2 and {{Xbox}}. Received mixed to terrible reviews and sold poorly. One of the last games produced by Interplay before they went bankrupt. [[CanonDiscontinuity Acknowledged as non-canon]].
* '''''VideoGame/{{Fallout 2}}''''': The extremely good sequel to the original.
* '''''VideoGame/{{Fallout 3}}''''': The wildly popular third installment, notable for the first inclusion of a CameraPerspectiveSwitch in the series.
* '''''VideoGame/FalloutNewVegas''''': An RPG by Obsidian very much in the same vein as ''Fallout 3'', released in October 2010. Despite not being a numbered entry in the series it is more of a direct sequel to ''Fallout 2'', continuing the story of the New California Republic and featuring a few returning characters, or their descendants, from the previous games[[/index]].
* '''''VideoGame/{{Fallout 4}}''''': Upcoming; unannounced.

Canceled titles:[[index]]
* '''''VideoGame/FalloutVanBuren''''': The original ''Fallout 3'', canceled due to Interplay's bankruptcy which caused the closing of Black Isle. Despite never being released, it is still considered [[LooseCanon partially canon]] and several story elements were reused in ''New Vegas''.
* '''''Fallout Extreme''''': Working title for a canceled project briefly developed by 14 Degrees East which would have been a sequel to Fallout Tactics released on the Xbox. It would have apparently been a first-person/third-person squad-based tactics game with strategic overworld management similar to Jagged Alliance, but never got past the concept stage.[[/index]]

Interplay, during its financial difficulties, proposed an MMO based on the Fallout franchise. [[http://www.interplay.com/about/article.php?id=40 They had been going forward with it,]] but then as of January 9, 2012, [[http://www.joystiq.com/2012/01/09/bethesda-settles-all-fallout-ip-related-lawsuits gave up the rights to carry on]] after a settlement with Bethesda.

'''Note: Tropes relating to the series and the Fallout Universe in general goes here. Please put tropes that applies to individual games in the series on their respective pages.'''
----
!!Tropes. Tropes never change.:
* AbdicateTheThrone: So to speak. Sometimes the diplomatic solution in regime-change type quests involves the officeholder stepping down willingly.
* AbsurdlyDedicatedWorker: Many robots in the series continue to (try to) carry out tasks assigned to them in the prewar years, completely unaware that over a hundred years have passed since America was devastated by nuclear war and their old masters are long dead.
* AbsurdlyHighLevelCap: Skills in the first two games cap at 300%, though for most of them 100% is all you need (and for the others, like combat-related skills, you tend to stop getting benefits from them just before 150%.)
* AbsurdlySharpClaws: In the possession of the [[MeaningfulName aptly named]] [[DemonicSpiders deathclaws]], genetically engineered killing machines with claws the size of machetes. In each game they are one of the toughest commonly occurring enemies, and their claws can even be {{MacGyver|ing}}ed into one of the more deadly unarmed weapons in the game.
* AbusivePrecursors: The Enclave, the remnants of the éminence grise of the United States federal government, the main antagonists of the second and third games.
** The Think Tank also qualifies. Mad scientists who were responsible for aiding in the experimentations of political prisoners for science.
* ActionGirl: Any female PC can choose to be an ActionGirl. There's even a Perk with this name for female characters (and Action Boy for male).
* ActionPet: The dog companions.
* AnAesop: The tentative aesop of the whole series, especially ''New Vegas'', is to let go of the past, both the glorious and the hardships, as clinging to them risks harm to the world of the present and misuse of the old war values and technology can lead to disaster. Several major antagonists cling to the past or use outdated and old values to guide their way, and it's why they're antagonists:
** The Enclave believes in America and wants to restore it to glory and retake their place as the ruling government. The reality is their power is in-name-only and they're really just a band of mass-murderers who want to rule the wasteland and have some really advanced technology to push around others as they try to enforce their self-declared claim.
** The Brotherhood of Steel is devoted to the Codex, which tells them they are to find and hoard old world technology to keep it out of the hands of those unfit to use it. The West Coast faction of the Brotherhood descend into KnightTemplar behavior and may be wiped out, the East Coast tosses the Codex aside in favor of helping people and prospers.
** Ulysses cannot get over the destruction of Hopeville and thinks Caesar and the NCR appropriate old world symbols with no respect or understanding of their meaning. You can talk him into seeing the hope in their actions and convince him to give them a chance to learn from their mistakes. Or if the Courier chose the Independent path, convince him that a free Mojave can prosper into the same kind of community, allowing the spirit of Hopeville to live again.
** Caesar's Legion from ''New Vegas'' is an especially blatant one, as their leader is intentionally seeking to rebuild a new [[UsefulNotes/TheRomanEmpire Roman Empire]] in the American West that's as faithful a replica of the first one as possible -- including the slavery, misogyny, and other assorted social ills that made it a rather rotten place to live by modern standards.
*** On the other hand Caesar's Legion are no more different than a larger band of raiders, as their economy mostly relies on RapePillageAndBurn and in the long run this is not a good means to maintain a real society, as they are not self sufficient as NCR, who can outlast Legion in a war of attrition.
** This extends into the backstory as well: the prewar United States was obsessed with the cultural norms and standards of an idealized utopian version of the 1950s, clinging almost religiously to the memories of the past. As a direct result of this obsession, America was [[CrapsaccharineWorld a dystopian hellhole under a thin veneer of happiness]], where the government actively used mind control and brainwashing to control the populace, political dissenters were sent to concentration camps to be used as test subjects for horrific genetic experiments, [[NoOSHACompliance safety regulations were virtually nonexistent]], and free, independent thought was seen as a menace to be stamped out at all costs. In short, America's obsession with the past led directly to its downfall.
** Another aesop is the impact one person can make on the world if they have the will to make a difference. In all four of the main series games, your player character becomes a MessianicArchetype, strengthening trade routes, leading struggling towns to prosperity, showing people the value of virtue and honor, and eradicating enemies that try to stamp it all out. ''New Vegas'' in particular has a strong theme of couriers and the messages and packages they carry delivering more messages than they may realize, and it's revealed your actions have shaped the fate of the entire West Coast long before you ever got hired by House.
* AfterTheEnd: Nobody knew who fired the first missile that triggered the apocalypse. By the end of the day, nobody cared. Everyone considered it would be the end of the world. But humanity still survived, mutated, blood thirsty, and completely shattered, but still the world moves on. The Great War isn't the end, simply one more sad chapter.
* AIIsACrapshoot: Mostly averted in the first two games -- in fact, on multiple occasions the AIs you encounter in prewar facilities are the only things that ''aren't'' malfunctioning. Played straight with [[spoiler:President John Henry Eden]], who turns out to be a computer, and also [[spoiler:considers himself a far greater president than any human because of this]]. Also played straight in Fallout Tactics - the BigBad is an insane AI and his army of robots, in a ShoutOut to ''VideoGame/{{Wasteland}}''. Despite this, Tactics has several interesting subversions. [[spoiler: Originally, the [[BigBad Calculator]] was going to be a perfectly rational computer, still soullessly following orders after its superiors were dead.]] This was changed in the game, [[spoiler: where the Calculator is now not a computer, but several dozen insane disembodied brains. The (completely sane) computer itself, which oversees the brain's actions, offers the protagonist the chance to upload his own, sane mind into the machine. This returns the calculator to sanity, and to your control. Depending on how nice you are, this could be an EarnYourHappyEnding or a BittersweetEnding. Simply destroying it works too, and that gives you the slightly good canon ending. Or you could shove the JerkAss's brain into it, creating the worst ending.]]
* AllCrimesAreEqual: Insofar as the idea of "crime" can exist in a society with no more centralized legal structure, any sort of wrongdoing will typically be met with the same sort of response -- everyone in the settlement attacks you. Take a step into a place you aren't allowed, steal a bottle of Nuka-Cola, even just being a {{Jerkass}} to the wrong person, and you can expect violence. Subverted in some settlements with jails and order, in these places you can actually be imprisoned. ''New Vegas'' gives a HandWave that NCR's troops are miserable due to the state of the Mojave and this is why they're so on-edge and don't care to punish crimes fairly, but it's still silly that a dozen armored troops will open fire on you just for taking a tin can off the floor that was marked as owned.
* [[TheAllegedCar The Alleged Everything]]: 80% of the tech you find is literally falling apart, broken, or [[AIIsACrapshoot trying to kill you]]. However, [[ILoveNuclearPower that]] [[InvisibilityCloak doesn't]] [[RobotBuddy mean]] [[HumongousMecha that]] [[FrickinLaserBeams technology]] [[PoweredArmor is]] [[KillSat useless]]. There's also an actual AllegedCar that doubles as a CoolCar, the Fallout 2 Highwayman.
* ApocalypseAnarchy: That's all the Fallout-verse is. Civilization collapsed, and it's up to you to save/destroy it.
* {{Atompunk}}
* AlternateHistory: The ''Fallout'' timeline diverges from the real world just after WorldWarII. Without the invention of the Transistor, the social, political, and technological status quo of TheFifties endured well into the late 21st century. The changes are minor at first but continue to cascade as the decades go by. Some of the changes include: NASA being replaced by the United States Space Agency (U.S.S.A.), American astronaut Captain Carl Bell becoming the first human in space instead of Yuri Gagarin (though the game mentions that Russia and China dispute this), the first lunar landing occurring a few days earlier then it did in RealLife and with a different module and crew, the states are divided into thirteen commonwealths in the 1960s and the American flag is changed to reflect this (it now depicts thirteen stars, twelve in a circle and one in the middle) and then there is the divergent technological development.
* AlwaysChaoticEvil: The majority of the Vault 87 Super Mutants in the third game (likely Justified by the FEV there having different properties). Averted with the Super Mutants created elsewhere in the first and arguably more the second, as well as ''New Vegas''. The various raider factions usually fall in this category too.
* AmmunitionBackpack: The Minigun, Grenade Machine-gun, Flamer, and Gatling laser from Fallout 3 onwards.
* AncientConspiracy: The Vaults were never meant to ''save'' anybody. [[spoiler:The Enclave, a cabal of members of the government and some powerful {{MegaCorp}}s, were considering colonizing an entirely new world once Earth got nuked to hell and back, but wanted to know if people could handle {{generation ship}}s. So the Vault Experiment was hatched: except for a handful of "control" Vaults, every supposed shelter would have a flaw that would test the population inside. One was deliberately overcrowded, one's door would never close all the way, one was inhabited by a thousand men and one woman (another had the same setup, but flipped the roles), one would pump hallucinogenic gas in the air systems, one was a test to see how an all-powerful Overseer would behave, and so forth, with cameras and uplinks sending all the data to a secret command and control Vault.]] Suffice it to say that your character, by comparison, got off light.
* ApocalypseHow: [[WorldWarIII The Great War]] caused a Planetwide Class 2. Fortunately, civilization has been slowly rebuilding, and by the time of VideoGame/FalloutNewVegas, several parts of the world are downright civilized
* ApocalypticLog: Being set AfterTheEnd there are many in the game series.
* ArcWords: "War. War never changes." Revisited and redefined in the ''New Vegas'' DLC ''Lonesome Road'', with the idea "war never changes, but men can".
** "Life in ''x'' is about to change" appears with rather satisfying regularity. For ''1,'' x was "the Vault" and in ''Tactics'' it's "the Brotherhood".
* ArmedWithCanon: When Creator/ChrisAvellone, who began his involvement in the series as a designer on ''Fallout 2'', got promoted to lead designer for the cancelled original version of ''Fallout 3'' he used the supplementary ''Fallout Bible'' which he wrote to kill off or retcon elements in the series he didn't like.
* ArtificialStupidity: Companions are ridiculously inept at times. To recount the many ways they are TooDumbToLive:
** In the first two games they will liberally use burst weapons and grenades if they have them and are able to use them, the former is very likely to kill you if you're in the way, and the latter, no companion has the Throwing skill needed to use grenades without them blowing up in their own faces most of the time. Not even the companions who are ''supposed'' to be good at it. On the plus side, enemies with burst weapons and explosives will gladly tear their own allies to shreds trying to hit you (one can sometimes even get characters with rocket launchers to use them at point blank range!)
** In the Bethesda-era games, companions cannot jump over any obstacle. If you jump up or down a cliffside, they will take the long way around. Better hope there aren't enemies in their way as they do it, too, because they're liable to get themselves killed off-screen fighting it.
** Also in the Bethesda-era games, "stealth" is not in ''any'' companion's vocabulary. They ''will'' enter Sneak mode and sneak with you, but the second they spot an enemy they charge in guns blazing. The only way out is to have them wait for you in an out-of-the-way area and go it alone.
** [=NPCs universally=] suffer from SuicidalOverconfidence and will eagerly run into combat with a dozen enemies, even if at a glance the player could tell they wouldn't survive to see their next turn for it.
** Due to some glitchy programming with how enemies handle aggro, it's possible to accidentally hit a friendly NPC while trying to shoot an enemy, and as a result your companions will presume you see them as an enemy and attack them, or the hit NPC will turn their attention to fighting you. Fight in towns with allies and enemies scattered between innocent bystanders, a single stray bullet hitting a civilian because they ran between you and the enemy could result in you having to massacre the town in self-defense.
** In ''Fallout 2'', if your stats are high enough, some enemies will flee combat from you. Then when you end combat, they will slowly walk back to where they were at the start of combat, likely triggering combat again. No choice to break the loop but shoot them dead.
** [=NPCs=] have no sense of moderation at all when it comes to combat, and will always use the most powerful weapon you gave them that has ammo. this is particularly annoying when giving your companions grenades or mines (so that you don't have to haul them around yourself) and they wind of throwing them at low level enemies like radroaches.
* ArtMajorBiology / ArtMajorPhysics: Don't expect realistic science in this series. It's inspired by pulp sci-fi after all.
* AssholeVictim: The United States in the backstory. Bearing little resemblance to its real-world counterpart, Fallout-universe America is a dystopian, jingoistic, genocidal imperialist state that thinks nothing of rounding up political dissidents at gunpoint and sending them to concentration camps to be used as test subjects in horrific medical experiments. Even after the nukes fall, it's really hard to feel sorry for Fallout's America.
* AttackItsWeakPoint: Robots take more damage when hit in the head with a targeted attack--but then again, so does every other enemy in the series.
** Wanamingos from the second game run away when they have crippled limbs. You ''could'' aim for said limbs...or you could just shoot them where their eyes are supposed to be, which strangely does the same thing on criticals (the game seems to count blindness under the "crippled limbs" banner) with a chance to do far more damage.
* AuthorityEqualsAsskicking: Seen in ''Fallout 1'' with the Lieutenant and the Master. Averted in ''Fallout 2'' with President Richardson, who's a standard unarmed civilian, and in ''Fallout 3'' with Colonel Autumn, who is only slightly tougher than a normal enemy soldier. Played straight in ''Fallout 3'' with BonusBoss Commander Jabsco of Talon Company (who has a rocket launcher and more health than almost any other character in the game), and Chinese General Jingwei in the ''Operation: Anchorage'' DLC expansion (who has an ''insane'' amount of health which, combined with his body armor, makes him the 2nd toughest enemy in the entire game next to the 15-foot tall Super Mutant Behemoth, possibly to encourage the player to [[TalkingTheMonsterToDeath convince him to surrender instead]], or maybe just an example of ExecutiveMeddling on the part of General Chase). Both seen and averted in ''New Vegas''. The NCR President and General are both bog-standard humans, while Caesar himself is only about as tough as an [[EliteMooks Elite Mook]]. Legate Lanius, however, is a frickin murder machine (for reference, the guy can take multiple anti-tank rounds to the face and still have more than 3/4ths of his health left).
* {{Autodoc}}: The TropeNamer. For the most part, they seem to work pretty well, but AIIsACrapshoot is still in full affect here.
** A good example of both instances occurs in the ''Old World Blues DLC'' for ''New Vegas''. The Think Tank were experimenting with a procedure to remove a subject's brain and replace it with a Tesla coil, yet retain their personality and memories. Unfortunately a technical glitch in their Autodoc caused the procedure to destroy the minds of all the test subjects, until the Courier's unique [[DoubleTap bullet-scarred]] brain forces it to reboot back to it's original settings, preventing them from becoming [[TechnicallyLivingZombie a Lobotomite]].
* BadassBookworm: Virtually any character build in any of the games that relies heavily on intelligence. The intelligence attribute contributes to skill points granted per level. As a result, high level intelligent characters will almost certainly have mastered a wide variety of skills, including ones related to direct combat. In order to even get access to [[HollywoodCyborg cybernetic combat implants]], one must first have substantial skill as a medical doctor.
* BallisticDiscount: You can kill pretty much anyone and take their stuff, shopkeeper or not, which includes killing them with a gun they just sold you and taking back your cash
* BeforeTheDarkTimes: Pre-War United States. While it was better than the Wasteland, in reality, it was really a CrapSaccharineWorld, and an EagleLand type 2.
* {{BFG}}: The "Big Guns" skill determines how well you can use them. Without question, any given game in the ''Fallout'' series has many more {{BFG}}s than any other video {{RPG}}.
* BigBrotherIsWatching: Actual quote from the museum of technology Vault tour: "Concerned about security? Our eye-on camera allows the Overseer to watch your every move. You'll never be alone again!" [[SarcasmMode Yay?]]
* BittersweetEnding: ''Fallout'' ends with the [[spoiler:player banished from the Vault forever despite saving most of West Coast humanity]]. Depending on the choices you made in ''Fallout 2'', a lot of places can end up badly despite your best efforts (or more likely, because of them). In ''Fallout 3'', [[spoiler:Lyons' HeroicSacrifice]] ending probably falls here, [[spoiler:as it's your ally sacrificing herself to activate Project Purity to provide clean, fresh water to the Wasteland. It doesn't solve everything, but it's a start. Of course, you're a cowardly bastard for not doing it yourself.]] The Corrupt and Coward Endings are [[DownerEnding even worse]]. Finally, one of the third game's optional sidequests is a setup for a ShoutOut to the ending of the first (and it hurts just as much). Pretty much every ending for New Vegas has some negative consequence to it.
* BloodyHilarious: The main purpose of the Bloody Mess trait, which causes your enemies to die in the most horrific ways from even the lightest of death blows. At its best, your enemy may spontaneously be reduced to ''[[LudicrousGibs bloody chunks]]'' from being hit by a ''[[ImprovisedWeapon teddy bear]]''. ''Fallout 3'' made it both amusing and helpful by tacking on a + 5% damage bonus. Even without Bloody Mess, you still get this effect if you score a kill in the right spot using VATS.
* BlownAcrossTheRoom: Most guns simply poke holes in enemies until they fall down, but the Gauss Rifle from ''Operation Anchorage'' will send enemies flying on a critical hit. It's a good idea to knock the particularly tough enemies down to render them temporarily out of action. Plus, sending giant scorpions flying around ass over teakettle is hilarious. In the original two games, certain critical hits with most weapons will blow enemies (or you!) right off their feet and send them tumbling across the room, sometimes knocking them unconscious.
* BodyHorror: Several, but none come close to The Master.
* BoringButPractical: In all games, Small Guns is the combat skill that will get you through with the least fuss. A hunting rifle acquired fairly early on will serve you well for a very long time.
* BossInMookClothing: Deathclaws are the Devil. In all games.
* {{Bowdlerise}}: German, and sometimes European in general, versions of the games are edited to remove gore, violence towards children, and other such controversial content. Besides that, the first game provides option to censor all non-PG level swear words (and some PG level ones too, apparently just in case).
* ABoyAndHisX: The protagonist and Dogmeat fits perfectly here (in fact, their concept is based in the [[ABoyAndHisDog Trope Maker]])
* BraggingRightsReward
* BrainInAJar: Appears repeatedly throughout the series, most notably the "robobrain" enemy.
* CanonDiscontinuity: Despite having almost no inconsistencies with previous games, ''Brotherhood of Steel'' isn't considered canon by Bethesda, likely due to the negative fan opinion of the game. ''Fallout Tactics'' is considered BroadStrokes canon due to design inconsistencies with the rest of the series.
* CanineCompanion: A dog is a staple companion character in all the ''Fallout'' games. Dogmeat serves as one for the player in the first two ''Fallout'' games. His descendant with the same name serves as the canine companion in ''Fallout 3''. ''Fallout 2'' also has two cybernetic dogs called K-9 and Robodog, and a "special encounter" jinxed dog called Pariah. ''New Vegas'' has cyber-dog Rex and in the DLC "Old World Blues" you can get his female "counterpart" Roxie. Dogs are a recruitable race in ''Tactics''. A dog can be obtained in ''Brotherhood of Steel'' with a perk. Non-player characters such as merchants and raiders occasionally have a canine by their side as well. The NCR and Caesar's Legion also join in with the puppy love. In ''Fallout 3'' there is even a perk called ''Puppies!'' so you can get a replacement for Dogmeat if he dies (you get one of his offsprings) And most players always regret when his dog companion dies, but generally gives a f*ck if its a human/ghoul/mutant/whatever companion. Hell!, basically one of the game premises is about you traveling the whole wasteland with a dog, so this trope is one of the main plots in the whole ''Fallout'' saga
* CaptainErsatz: Say "hi" to Riddick in ''Tactics''.
** One DummiedOut recruitable NPC in ''2'' is basically Cat from ''RedDwarf'' (except that he's now a pre-war soldier turned into a HalfHumanHybrid in DNA-splicing experiments instead of a hyper-evolved cat.)
* CartographySidequest: In ''Fallout 3'', you can map out the Wasteland for Reilly after you've saved her squad in exchange for caps. Two smaller ones also appear in ''Fallout 2''. Vault City asks you to map the grid squares surrounding Gecko and to find a route to NCR. Technically, you just have to get to NCR. It doesn't matter if you go by way of New Reno and San Francisco.
* ChainsawGood: The 'Ripper' weapon is, quite literally, a chainsaw stuck on a one-handed sword hilt.
* ChainsawGripBFG: Many heavy weapons are carried this way, particularly the various forms of [[GatlingGood Minigun]].
* TheChosenZero: When you have a character with low intelligence, pay a visit to your Vault or your native village and the locals will all express various levels of horror that your drooling moron of a character is the only thing standing between them and total destruction.
* ChurchOfHappyology: Hubology. See the trope's page for details.
* ClusterFBomb: Used quite a bit. In the first three games there is an option so that the offensive words are bleeped out and/or replaced with less offending words.
--> ALARM! Intruders in the camp! Wake up you piss ant sons of bitches! I'll swear I'll cut the balls of anyone I don't see fighting! Get up you curs! If they escape, God help me, I'll burn you motherfucking still to the ground!
* CombatPragmatist: Throughout the series, you'll shoot opponents in the legs to cripple them, shoot them in the eyes to blind them, and use combat drugs and cybernetic implants to give yourself an edge in battle. Even out of battle, major factions often have discreet and indirect ways to break their power without gunning them down directly.
* CoolShades: equipping a pair of these gives a + 1 to Charisma. There's also a unique pair of Lucky Shades, which give the wearer a + 1 to [[ExactlyWhatItSaysOnTheTin Luck]].
* CorruptPolitician: There aren't many elected officials, but for those there are, this trope is usually in full effect.
* CowboyBebopAtHisComputer: A rather hilarious example, as some dubious journalists saw a ''Fallout 3'' promo shot of a ruined Washington, D.C., without a watermark and assumed it was created by terrorists as a warning. [[http://www.destructoid.com/daily-mail-thinks-fallout-3-artwork-is-terrorist-propaganda-88282.phtml Seriously.]]
* CrapsackWorld: The world is a ruined, post-apocalyptic wasteland, and that's just the tip of the iceberg. It only gets worse, folks. There are giant radioactive insects and arachnids, really unsociable mutants, proto-zombies of every flavor and variety, mass starvation, dehydration, radiation sickness, rampant slavery, murder on a scale that can potentially reach genocide, and generally life itself only continues to remind the human race of how royally they screwed up the planet. Sure, there are examples of civilization trying to rebuild itself, but that results in places like the den of vice New Reno and fascist communities like Vault City. Still, the player can - should they so choose - leave the gameworld a little better than they found it. Or just make it massively worse, of course...
* CripplingTheCompetition: Throughout the series, you can use target shots to aim at enemy body parts. Shooting the eyes or head lowers their accuracy, shooting the arms may prevent them from using certain weapons, and shooting the legs lowers movement speed.
* CriticalExistenceFailure: Played straight in general: everything, whether animal, vegetable, or mineral, fights just as well at 1 HP as at 100. However, critical hits to a specific location (usually eyes or a limb) can cripple that part and reduce stats or fighting ability.
* CriticalFailure: A prominent feature in the first two games. You can drop your weapon, lose your ammo, lose your turn, injure yourself, and so on. At the extreme end, energy weapons can blow up in your hands. This can also apply to non-combat skills, jamming locks and triggering traps. Oh, and the Jinxed trait in the first two games made it happen to everyone around you, which could make the early game very very challenging since every miss had a good chance of being a critical miss. You could, however, make up for most of the negative effects of the trait by having a high LuckStat, and you furthermore chose [[GoodOldFisticuffs Unarmed]], which does not have very harsh punishments for failures, as your primary combat skill, you suddenly have a very effective character build.
* CriticalHit: Each game has its own Critical Hit mechanics:
** The Sniper perk for ranged weapons in ''Fallout'' and ''Fallout 2''. It made a separate roll for a critical (equivalent to your Luck * 10) after rolling for a successful hit depending on the character's LuckStat. If Luck was maxed to 10, every single successful hit would automatically roll critical. Even more damage could be applied through the use of targeted shots.
** The Slayer perk, only in ''Fallout'' and ''Fallout 2'', was the Sniper perk equivalent for hand-to-hand characters. Instead of rolling for a critical, every hit was automatically upgraded to a critical.
** All the main games allowed for a type of critical that would trigger if the target was struck while the player was undetected. Fallout 1, 2, and Tactics had the Silent Death perk, which would enable a critical when sneaking an [[BackStab from behind]], and only while unarmed.
* CriticalHitClass: In earlier titles, this was a very common endgame build, with perks that granted stratospheric critical rates and improved rolls on the critical table. Sniper gave guns a critical chance equal to 10x your luck stat, while Slayer gave automatic melee criticals.
* CursedWithAwesome: Arguably the ghouls are. Sure, they make third degree burn victims look pretty, but they are immune to radiation and can't apparently die from old age. In fact, if they were able to breed they might be considered an improvement over humanity.
** A downside to the Ghouls aside from their appearance is their possibility to go feral. It's not a guarantee that every Ghoul will go feral but it happens when their brain physically deteriorates from too much radiation poisoning. But a feral Ghoul is ''completely'' insane, though still physically capable (though they don't (can't?) use weapons). The game even rewards the player with positive karma for killing feral Ghouls, so a positive karma player will actively hunt down feral ghouls to the point of genocide just to farm up their karma, which makes immortality not so awesome in some respects.
** Super Mutants were specifically designed to be superior to humans in coping with the harsh Wasteland, but it came at the cost of them being sterile and not very bright (with a few exceptions).
* DamageReduction: Damage Threshold and Damage Resistance, with slightly different formulas in each game.
* DarkLordOnLifeSupport:
** MadScientist Dr. Stanislaus Braun from ''VideoGame/{{Fallout 3}}'' has spent the past 200 years in a VR/life support pod overseeing the Tranquility Lane simulation, and is terminally dependent on it, as he tells the Lone Wanderer in the sim.
** Mr. House from ''VideoGame/FalloutNewVegas'', who has managed to prolong his life by confining himself to a sophisticated life support chamber. [[spoiler: Opening the chamber will ensure his eventual death due to being exposed to outside contaminants]].
** Caesar isn't technically on life support, [[spoiler:but has a crippling brain tumor]], hence Lanius being DragonInChief.
* DeadpanSnarker: ''Every'' protagonist.
* DeathOrGloryAttack: In the first two games, using miniguns against heavily-armored foes tends to serve as this. Either it bounces off harmlessly, or the wielder scores an armor-bypassing critical and tears their target to bloody chunks.
* {{Deconstruction}}
** The first two games (and, to an extent, ''New Vegas'') deconstruct the IdiotHero. True, generating a hero with an Intelligence score of 3 or less makes you have [[CrowningMomentOfFunny hilarious conversations]] with the world; but you get fewer skill points from leveling-up, you are locked out of about 90% of the quests, and most of the [=NPCs=] [[DudeWheresMyReward don't give you anything for your efforts]] and [[DudeWheresMyRespect treat you like a joke.]] Furthermore, an IdiotHero can't really make a lasting impact on the Wasteland in general. Sure, you save your hometown, but everyone else is pretty much screwed.
** The entire series is a deconstruction of the supposed "moral purity" of TheFifties, showing [[AfterTheEnd exactly what would happen]] if the MoralGuardians who say this had their way and the ''actual'' 1950's continued forever.
* DefectorFromDecadence
** The talking Deathclaws in ''Fallout 2''.
** The Columbia chapter of the Brotherhood of Steel deviated from their original mission (gathering old technology) to helping the inhabitants of the wasteland. This change lead to a significant number of [=BoS=] members claiming Lyons was a defector. So the Defectors from the Defector from Decadence became the Brotherhood Outcasts, who are a lot less altruistic, especially if they see you handling any piece of technology more sophisticated than a gun.
* DesertSkull: The series loves this trope.
* DesignatedHero: [[invoked]] The player can make their character one. You can openly be a sadistic bastard who steals, lies, backstabs and murders their way through the wastelands, but by the end of the game your character will be a hero known across the Wastelands for their great deeds. Played straightest in ''Fallout'' and ''Fallout 2'', where your character will become famed in later games regardless of their actions towards the other settlements. Played with in ''Fallout 3'' where there were evil endings and characters reacted appropriately to you taking them. Averted in ''New Vegas'' where if you join House or NCR with negative karma, people and the endings will acknowledge you as an evil person that just happens to feel like working for the good guys, and if you join the Legion you become villified along with them. The narrator will even dwell a bit on the contradiction of a character with good karma helping the Legion to archive their goal.
* DirtyCommunists: Going by Pre-War propaganda, the entire nation of China. You get to fight a simulation of them in the ''Operation: Anchorage'' DLC. Likewise, [[HumongousMecha Liberty Prime]] figures anyone who gets the receiving end of one of his nuclear footballs is a communist, regardless of what he's actually fighting. Then again, that just [[RuleOfFunny makes it better]].
* DisasterDemocracy
* TheDitz: Harry, who is easily the dumbest Super Mutant in the ''entire series''.
* DivergentCharacterEvolution: The Brotherhood of Steel "split" into three distinct factions after ''Fallout 2'', each faction demonstrating very different behavior:
** The West Coast side devolved into KnightTemplar, becoming hostile to any outsiders they deem unfit to use advanced technology and using force to keep their bases safe, being very hesitant to accept aid from outsiders. They quietly acknowledge however that their xenophobic policies will get their faction exterminated since their numbers are dwindling and their technology is becoming outdated, but they keep to the codex anyway.
** The East Coast Brotherhood led by Elder Lyons decided that their advanced technology would be put to better use helping people rather than just being hoarded, so they turned their attention to patrolling the wasteland trying to protect people from mutants and raiders, their ranks are open to outside recruits, and they offer aid to outsider projects they deem worth the manpower.
** The Brotherhood Outcasts left the East Coast chapter because they felt Lyons' betrayed the Codex, and while they take the name "Outcasts" as a jab at him, they consider themselves the ''real'' Brotherhood of the East Coast and see Lyons as a traitor who will be brought to justice. They are willing, though reluctant, to accept aid from outsiders and will open their base to one they trust enough, but do not offer membership, bolstering their ranks with robots instead. They patrol the wastelands salvaging old technology, and their patrols deal with hostiles like mutants and raiders. Interestingly, the "outcasts" are closer to the Brotherhood's behavior in the original ''Fallout'' than either the East or West Coast sides.
* DivergentEvolution: Feargus Urquhart's [[VideoGame/FalloutNewVegas Fallout: New Vegas]] is what ''Fallout 3'' would have been. Considering Washington D.C. is said to be destroyed in both Wasteland and Fallout 1, the concept of Fallout: New Vegas can bee seen as [[ExecutiveMeddling "That's a nice world you have there, but]] [[GoodDaySir we like the one we made better."]] The fans go both ways on this one.
* DoomedHometown: The first two games start out with the player having to stop their hometown's impending destruction.
* DownerEnding: If you agree to [[http://www.youtube.com/watch?v=PfyqlMBeQFU help the master in Fallout.]]The player character is dipped in FEV, Vault 13 is invaded by mutants, everyone is slaughtered and what looks like the Overseer dies in a futile last stand. The same thing also happens on day 500(or 400, if you give away the location of Vault 13)if the mutants are not defeated.
* TheDragon: Lieutenant to the Master in ''1'', Horrigan to Richardson in ''2'', and Colonel Autumn to Eden in ''3''. In ''Vegas'', Caesar's right hand is Legate Lanius, while President Kimball's number two is General Lee Oliver. [[spoiler:Benny]] was this to Mr. House (and you can take his place), and [[spoiler: Yes Man is this to you, if you choose the Independent path]].
* DragonTheirFeet: In ''Fallout 2'' and ''3'', you don't confront Enclave superweapon [[spoiler:Frank Horrigan]] or Enclave military commander [[spoiler:Colonel Autumn, who will "spare" you with a successful speech check]] until ''after'' you've ''already'' killed the BigBad President and wiped out the Enclave's main base. Likewise, in ''Fallout'', the final two missions are to kill the BigBad and to destroy the Super Mutant vats (guarded by TheDragon), and you can tackle them in any order you want (Although canonically TheDragon and the vats were destroyed after the Master's death). Likewise, in ''Vegas'', [[spoiler: Legate Lanius and General Oliver lead the Caesar's Legion and NCR forces during the game's final battle, despite Caesar himself and President Kimball both likely having died earlier in the game.]]
* {{Drive-In Theater}}: You find a few in ''3'' and ''New Vegas''. In the latter, it's where you start off the Old World Blues DLC.
* DropTheHammer: Sledgehammers and Super Sledgehammers.
* DrugsAreBad: Performance-enhancing drugs (Mentats, Buff-Out, Psycho, Med-X, Jet, [=UltraJet=]) are all over the place in each game, but also can cause addictions each time they're used - and the withdrawal symptoms that result affect a player's statistics in a negative manner until cured (or unless you keep taking the drug). There are also characters like Cassidy in the second game who can die if they use drugs, and Super Stimpaks can be used as a covert method of assassination [[spoiler:as the side effects will cause enough damage to kill President Dick Richardson (or any other 'friendly' NPC), allowing you to take their items without fear of the reprisals that direct action would cause. One particular NPC (Councillor Westin) will explode if you use one on him!]].
** Interstingly inverted in Fallout 3 and New Vegas, where addiction is a non-issue if drugs are taken in moderation (ie no more than once every 30 to 48 in-game hours) but alcohol always has a chance of addiction. [[WriterOnBoard Considering Bethesda has a habit of making alcohol the bad item in]] Franchise/TheElderScrolls series while making in-universe illicit drugs useful, this isn't surprising. On the other hand, New Vegas features the Fiends, an entire gang of junkies who are undeniably the biggest scumbags of the game.
* DumpStat: Strength. All it affects in any game is carry weight, melee damage, and in some games your hit points and which weapons you can use. Carry weight is rarely an issue since there's always companions to unload stuff on, and melee attacks are never used except for a handful of quests and in character builds focused on it. As for weapon usage, most guns don't have a Strength requirement higher than the base 5, and by the time you want to use the larger guns that need more, you have access to Power Armor and implants to increase Strength.
* {{Eagleland}} The prewar United States depicted itself as Type 1 but in fact was heavily into Type 2. ''Fallout'' is one of the very few cases in Western media in which the USA is actually depicted as being outright villainous; the prewar government was an Orwellian nightmare that makes the real-world Soviet Union look positively warm and fuzzy in comparison, and their successors, the Enclave, are ''even worse''.
* EarnYourHappyEnding: ''Fallout 2'' and ''New Vegas'', especially.
* EasterEgg: Most of the 'special encounters' in 1, 2 and Tactics. Some are just there to be goofy, while some (while still pretty goofy) offer some awesome weapons and equipment.
* ElaborateUndergroundBase: The Vaults themselves. And let's not forget the ever so expansive Raven Rock. Both [[JustifiedTrope justified]], as some of the Vaults are supposed to hold hundreds, and in a few cases thousands, of people, and Raven Rock is based on the [[http://en.wikipedia.org/wiki/Raven_Rock_Mountain_Complex actual Raven Rock government complex]].
* EldritchAbomination: Prolonged FEV exposure can mess you up in an impressive manner. [[spoiler: The Master began as a human who got dipped in an FEV vat for an unusually long time, and emerged as a [[BodyHorror formless, tormented mass of flesh]] that expanded throughout the entire base, merging with its electronics and computer systems, and absorbing any other life form it found into itself, becoming a demented HiveMind that viewed itself as a perfect being]].
* EliteMooks:
** ''Fallout 1'' had the cloaking-device-equipped Nightkin as the Super Mutants' EliteMooks.
** ''Fallout 2'' had the Enclave Soldiers in the ENCLAVE Oil Rig, wearing Advanced Power Armor (Mk. 1 & 2), equipped with energy weapons and full of stimpaks.
** ''Broken Steel'' includes the Enclave's elite Sigma Squad. And the Hellfire Troopers.
** ''New Vegas'' has NCR Rangers and Centurions.
* EscortMission: Fairly common in this series.
* EveryCarIsAPinto: And not just regular Pintos, ''nuclear-powered'' Pintos. Broken down, nuclear powered Pintos. That produce [[ArtMajorPhysics a mini-nuclear explosion]], complete with ''mushroom cloud'', when you shoot them.
* ExecutiveMeddling: The reason why two of the MultipleEndings in the original game were cut, because of the GreyAndGreyMorality content. It's also the reason for ''Fallout 2'' having the worst JustifiedTutorial ever.
** This was also the reason for the the drug "Med-X." It was originally morphine.
* ExpansionPack: Bethesda Software added a lot to the main questline of ''Fallout 3'' with the downloadable addons, including one module that revisits a key battle in the background of the ''Fallout'' world (the Battle of Anchorage), another that allows players to visit a city mentioned in passing by another NPC, and one that promises to address the brevity of the main questline by allowing players to continue the game [[RetCon after the controversial ending]].
* ExtremityExtremist: It is possible to play this way in all games.
* {{Expy}}: In Fallout 3, the [[http://fallout.gamepedia.com/Enclave_officer Enclave Officers]] greatly resemble the [[http://starwars.wikia.com/wiki/File:Imperial_meeting_SWGTCG.jpg Imperial Officers]] of StarWars.
* EyeScream: Eyes can be targeted, as can the groin, and is in fact a better target (blinding, one-hit kills). Get your accuracy with any weapon class up to a high enough level, and shots ''to the eyes'' can and will solve most of your combat-related problems. Eyeballs are also part of the gibs in ''Fallout 3'', and if a critical hit to the head is scored they will fly out at high speed, sometimes hilariously towards the camera in VATS mode. Lampshaded by one character's combat taunts: "There's nothing wrong with you that a critical to the eyes won't cure."
* FantasticDrug: Jet, Mentats, Psycho, and Buffout, the series stand-bys.
* FantasyCounterpartCulture: The most blatant is [[TheEmpire Caesar's Legion]], which was modeled in-universe on TheRomanEmpire and [[ShownTheirWork is sometimes hard to tell apart from the real thing]]. The [[TheFederation New California Republic]] is very much like the pre-war United States. The Shi Empire is pretty much ImperialChina reborn. And while probably not deliberate, [[TheOrder Lyons' Brotherhood of Steel]] has a lot in common with early {{Prussia}}.
** Most can be justified at least marginally considering that the universe of Fallout is not based on some other world, but a divergence of our own world, so cultures would have tried to base themselves off of some kind of history in many cases. An inversion of sorts in some of the cultural inclusions as they end up based not on real world historical cultures, but fantasy sources, such as books or movies that were popular in or around the 1950's.
* FateWorseThanDeath: This has been the case since the first game and was used for its TalkingTheMonsterToDeath option. The handful of talking Super Mutant [=NPCs=] in the first two games occasionally mention it.
** The feral ghouls. Especially how they're portrayed in ''Fallout3'' and ''VideoGame/FalloutNewVegas''. They're ghouls rendered [[AxCrazy completely insane]] and hardly sentient anymore. You'll get positive karma by [[MercyKill killing them]].
** Robobrains. Those human brains used as central processors were ''not'' volunteers, they're enemy POWs, political prisoners, conscientious objectors, executed criminals (both sane & insane), and deserters whose brains were forcibly extracted ''while they were still alive'', shoved into a robot body while perfectly conscious and aware, and left stuck in a never-ending nightmare, kept constantly awake and alert by the machines they're wired into and completely incapable of doing anything at all they aren't specifically programmed to do.
* FighterMageThief: Technically the [[FunWithAcronyms S.P.E.C.I.A.L.]] system is classless. However, in the first two games there are three character templates that are implied to be optimal for completing the game: the "warrior", "thief" and "diplomat" templates. The three premade characters in both Fallout 1 and 2 always fit these templates.
* FinalDeath: Once a team member is killed, they're dead forever. This is Earth, not [[ForgottenRealms Toril]], and there are no such things as resurrection spells. In the first two games, ''every'' NPC (including essential quest killers) is killable. In ''Fallout 3'' every character except children and those deemed essential are, meaning you can always progress in the game but can screw yourself out of a lot of potential loot and XP. In ''New Vegas'', your allies are just [=KOed=] for a few seconds in normal mode. In Hardcore, though, it's FinalDeath.
* FiveTokenBand: Your party can include humans, ghouls, Super Mutants, assorted robots, various dogs, and even a friendly neighborhood Deathclaw!
* FlushingEdgeInteractivity: Subverted, as the player can actually drink from the toilet — though the water, like all non-purified water in the game, is irradiated.
* FromNobodyToNightmare: [[NamesToRunAwayFromReallyFast Deathclaws]]. What pre-war animal did they mutate from? Jackson's Chameleons.
* FunWithAcronyms: Loads of them
** '''S'''trength. '''P'''erception. '''E'''ndurance. '''C'''harisma. '''I'''ntelligence. '''A'''gility. '''L'''uck.
** '''G'''eneralized '''O'''ccupational '''A'''ptitude '''T'''est.
** '''G'''arden of '''E'''den '''C'''reation '''K'''it.
** '''V'''ault-tec '''A'''ssisted '''T'''argeting '''S'''ystem.
* GameplayAndStorySegregation: Fawkes is a Super Mutant, and also a potential follower. Naturally, Super Mutants are not exactly well-liked, but because Fawkes is a follower, no one will bat an eyelash in even the most heavily populated of places. Even the Brotherhood, which makes a living hunting these monsters, will not care. Fawkes lampshades this by commenting on how surprised he is that people won't shoot him on sight simply because he is in your company. It is subverted in one instance, though; if you bring Fawkes along for the Reilly's Rangers quest, the Rangers on the roof will turn hostile the second you hit the steps. They've been fighting Super Mutants for a while now, after all, and the sight of another isn't helping. Of course, if you tell Fawkes to hang back, greet them, then pick him up, they will not care.
* GatlingGood: Miniguns are generally pretty good weapons, though not particularly reliable against heavily armored opponents. They tend to veer between LudicrousGibs and just bouncing off.
* GayOption: In ''Fallout 2'' there are same-sex {{Optional Sexual Encounter}}s available for both sexes, [[MostWritersAreMale though significantly more for women than men]] (in fact, there are more lesbian options than straight ones for women). ''Fallout 3'' mostly avoids the issue altogether by not even including a ''straight'' option. Male and female player characters can hire Nova, the town prostitute in Megaton, and Bittercup, the town goth in Big Town, develops a crush on the player regardless of gender (though her crushes are mostly her turned into a PerkyGoth and giving you whatever crap she found in the patrols). ''New Vegas'' adds 2 new perks, Confirmed Bachelor for men, and Cherchez La Femme for women, which will give special dialogue options when dealing with an NPC of the same sex, (and a 10% damage bonus against the same sex) much how the Black Widow and Lady Killer perks function when dealing with the opposite sex. If you have this perk, you can recruit one follower (which one depends on your gender, there's one for each) bypassing the usual skill check needed by flirting with them, essentially giving you a same sex romantic option. If you are a man with the perk, you can also get all your stuff repaired for free any time you want by flirting with an NPC and asking him to be "friends." Unrelated to the perk, but you can also hire same-sex prostitutes, male or female, in New Vegas if you should so choose.
** In ''Fallout 1'', rescuing Sinthia at the hotel in Junktown will get the player a 'reward'… whichever the main character's gender may be.
* GenerationXerox: Everyone from the original Vault 13 Dweller's bloodline seems to have pure {{Badass}} embedding in their genes. First there is the original Vault Dweller, who stops a plot to turn the population of the Wasteland into super mutants by destroying 2 underground lairs, saves quite a few communities along the way, and ends up as the chief of a tribe, before going adventuring again in old age, presumably dying somewhere out in the wastes. Then, 80 years later, their grandchild stops a plot to commit a holocaust on the Wasteland by blowing up an oil rig, again saving some developing communities along the way, and ends up becoming head of a new civilization. And in one of the endings in ''Fallout 2'', you father a bastard-child with one of the women from the Bishop crime family, who, already at age 13, takes control over the family, and leads it to victory over New Reno's other crime families and, despite been a powerful mafia boss in crime ridden city at a time where the average lifespan is about 35 years, manages to live the age of 73, where he dies peacefully in his sleep. This ending was confirmed as canon in ''New Vegas'', by Bruce Isaac, who fled town after steeling from the casino and sleeping with Mr. Bishops' daughter.
** Likewise, the Cassidys are also hardasses with a tendency to associate with legendarily awesome people.
* GeneticEngineeringIsTheNewNuke: The "forced evolutionary virus," although it doesn't quite work as intended.
** And of course because this is Fallout, the prewar governments love of genetic engineering, though great, doesn't hold a candle to the prewar love of nukes.
* GeniusDitz: In every game you can set your character's Intelligence so low they're incapable of speaking properly and can't understand what others are saying either. Doesn't stop you from using skill points to let them pick locks, hack computers, and be master doctors. It'll just take longer since lower Intelligence means fewer skill points.
* GiantRobot: ''Fallout Tactics'' features a few as enemies towards the end of the game. Best dispatched at long range with volleys of plasma/laser fire.
** ''Fallout 3'' Liberty Prime.
* GlobalCurrency: Bottle caps in the first game, endorsed by the Hub Trading Companies due to their rarity and the difficulty in counterfeiting them. New California Republic Dollars in the second, as the NCR is the dominant power in the region. Ring pulls in Tactics. Caps again in Fallout 3, though this time without a justification as to why. Caps again in New Vegas because the NCR lost the gold it backed its dollars with and the trading companies are honoring old promises. There is NCR paper money and Legion coin, but those are treated as barter items in most cases.
* GoodIsNotNice: The Brotherhood of Steel in general, though it does have a few genuinely kind members.
** Despite being one of the nicest major factions in the series, many of the New California Republic's actions in ''Fallout 2'', such as hiring raiders to attack Vault City and having dealing with the crime families at Reno, are morally questionable. There are also certain political elements within the government who are attempting to turn the alliance into more of fascist police-organization. As one NPC puts it, "their heart is in the right place, but their head is up their ass!"
* GoodIsNotSoft: A universal truth in the main four games. You can play an AllLovingHero who upholds morality and protects the innocent, but there's a lot of nasty people out there looking to ruin your hard work, and they are not going to survive the attempt.
* GrenadeTag: Planting explosives on someone via pick-pocketing.
* GroinAttack: The first two games featured the groin as a legitimate target on any creature. Yes, you can punch rats in the groin. Even better, you can sledgehammer a rat in the groin. Which is still nowhere near as twisted as [[BloodyHilarious firing a rocket at a child's groin]].
* HegemonicEmpire: New California Republic have annexed regions by military force, but they prefer to expand through peaceful settlement and inviting existing frontier settlements to join them. By the time of VideoGame/FalloutNewVegas, it is engaged in a three-way power struggle over control of New Vegas, a very advanced, prosperous, and independent settlement.
* HelloInsertNameHere: Used in the first two games for all non-voiced dialogue.
* SociopathicHero: Many dialogue options in invoke this character trope.
* HeroOfAnotherStory: Many, but especially your companions.
** Harold, who has lived for almost four centuries, been in every game but ''Tactics'', has wandered almost the entire United States Wasteland, was buddies with [[BigBad the Master]] before they were both mutated, and [[spoiler: may eventually bring life back to the world.]]
** In New Vegas all of the [=DLCs=] have a character who is this to some extent, and nearly all of them are (or at least presented as) antagonists at some point. In ''Dead Money'' and ''Lonesome Road'' Father Elijah and Ulysses respectively went on long incredible journeys involving post-war organizations, settlements, and tribes otherwise unmentioned in the series. In ''Honest Hearts'' there is Joshua Graham, who was formally both a Mormon missionary and the legate for Cesar's Legion. Dr. Mobius of ''Old World Blues'' was a prewar scientist and BrainInAJar who eventually used SCIENCE! to prevent his former colleges from ravaging the post apocalyptic world.
* HideYourChildren: Completely averted in ''Fallout 1'' and ''Fallout 2''. Kids are a regular part of the civilian population, and you can freely blow them away in a variety of gruesome ways. The game even produces funny * wink* * wink* * nudge* * nudge* combat dialogue if you do so. Further, in one town, you are practically ''encouraged'' to do so, as the little bastards hang around in front of quest-critical stores and attempt to pickpocket you (and no matter how high your steal skill, it's nigh-impossible for you to take what they have back; you have to buy them from the merchant they report to). Note, however, that actually killing children will mark you as a "Child Killer," which causes pretty much everyone except the most evil characters to hate you on sight. This was taken literally in the European releases of both games, in which the children were simply made invisible (they're still there - they will steal from you and occasionally say things and can be killed with explosives). ''Fallout 3'', though used the "children are present but invulnerable" variant (though you can at one point help a slaver kidnap one and ''sell another into slavery yourself'').
* HorrorHunger: Cannibalism is a mutation. Ordinary humans who eat human flesh too often sicken and die, but a subset have a natural hunger for human flesh and an ability to eat it without getting fatal rad poisoning (at least not as fast). Several organizations of cannibals exist who have either kicked the habit, [[WarmBloodbagsAreEverywhere tried to]], or [[VegetarianVampire found a substitute]].
* HumanResources: In ''Fallout 1'', your character could discover through simple investigation that the meat used by Iguana Bob, the local fast food vendor, was secretly made out chopped up human cadavers. If the player has high enough stats they can blackmail Bob. By ''Fallout 2'', his great-grandson has built an entire franchise...
* HundredPercentHeroismRating
* HumanoidAbomination: Frank Horrigan, the genetically engineered synthetic cyborg homocidal maniac specially created by the Enclave, who is forever sealed in a suit of power armor that continually pumps him with life support. ''Dead Money'', the VideoGame/FalloutNewVegas DLC, has the Ghost people. The Cloud apparently changed normal human beings into feral, nocturnal, gas proof, limb-regenerating, and [[MadeOfIron hard to kill]] abominations sealed in hazmat suits, with their only purpose now being to stab, throw a spears, and chuck bombs.
* HyperactiveMetabolism: Played straight, eating nets you a few HP. This can also be gained as a perk, it increases your vulnerability to poison and radiation, but increases the health you get back from food and medicine. Builds favoring the Survival skill over Medicine in New Vegas can actually heal gunshot wounds better by eating than by using stimpaks. There's even a drug ("Hydra") that can regrow broken limbs!
* HypocriticalHumor: Liberty Prime has a few choice slogans that fall into this category. "'''Democracy is non-negotiable!'''"
* IconicOutfit: Each game has one.
** The original has the T-51b Power Armor.
** Fallout 2 has the Enclave Advanced Power Armor Mk2.
** The third game has the downgraded T-45d Power Armor.
** New Vegas has, to buck the trend, not Power Armor, but the NCR Veteran Ranger Combat Armor, aka the Black Armor.
** All games except the second, however, have the min characters wear an armored jumpsuit as their most famous attire.
* IdenticalGrandson: ''Fallout 2'' has you play as the grandchild of the original game's protagonist, and since the game recycles the sprites for the main character, you look exactly alike. The uncanny resemblance is commented upon by Tandi, a character appearing in both games.
* IdiotSavant: Your character can be mentally challenged to the point of being incapable of forming coherent speech, but can still learn to hack advanced computers and repair complex machinery. Lampshaded by Loxley in the original:
--> '''Loxley:''' ''Bloody fine job making it through the defenses, mate! I'm rather impressed. Toss me your name!''
-->'''You:''' ''Nuhhh?''
-->'''Loxley:''' ''Well, "Numa-numah-num-nuhhh", how did a total moron, such as yourself, get past my defenses? Sorry, no idiot savants allowed, we like good conversation here. Jasmine, show our drooling friend the door please.''
* ILoveNuclearPower: Both subverted and played straight. Most of the wildlife has been hideously mutated by the Forced Evolutionary Virus, which has ''itself'' been mutated by the radiation, which is what results in the weird mutations. This, of course, leads to giant cockroaches, flies, and scorpions, provides ghouls with immunity to radiation poisoning [[BlessedWithSuck and a nasty skin condition]], as well as giving the player character a few perks, rather than premature baldness, brittle bones, sterility, or a slow death. On the other hand, an excess of radiation will kill you and ruin your stats until you deploy the [=RadAway=]. Oh, and make you grow an extraneous toe in ''Fallout 2''. Certain perks also cause you to heal[=/=]regenerate broken limbs when irradiated.
** There was also a bug (or possibly intended?) in Fallout 1 and 2 that allowed your attributes to "mutate" (numbers changed, not always for the better, sometimes far far better) if you took extreme doses of radiation (near deadly levels) and then got cured after living with it for a while. Tho it did not seem to "work" if you got cured by doctors. Only by using lots and lots of Rad Away.
* ImAHumanitarian: The cannibal perk, along with some stuff in the first and second. [[spoiler:Andale]] in the third. ''New Vegas'' even adds the option to harvest dead bodies for a snack later. On top of that, cannibalizing a corpse is the ONLY way to instantly regenerate health in Hardcore mode.
* ImplacableMan: The Khans are an implacable ''organization'' of raiders. Even if you storm their base and wipe them out down to a man (which has canonically happened twice now,) there will always be a survivor somewhere who will revive the band and continue their vendetta against the NCR.
* ImplausibleFencingPowers / MultiMeleeMaster: If you have a high enough melee score, you can use anything from a steak knife to a flaming lawnmower blade to a chainsaw to a genuine Masamune katana.
* IndestructibleEdible : All the packaged foodstuffs you find are 100-210 years old, and perfectly edible, although irradiated, and the soda is "warm and flat". Perhaps Justified, because irradiated food won't spoil (although the preservatives should have turned toxic by then).
* InescapableAmbush: Having a very good or very bad (karmically) character is a good way to have a price put on your head. A very good character is less likely to encounter an ambush that's inescapable, though, particularly with a high level of Outdoorsman. The ambushes in general start being (somewhat) escapable in ''Fallout 3'', as long as you don't Fast Travel, or exit from underground too often. That game decides to add a separate and special InescapableAmbush [[spoiler:set by the Enclave right after you get the G.E.C.K.]], but that's a [[CutsceneIncompetence cutscene]] rather than combat-based. And if you switch your karma during your career, you'll end with both side hunting you (and shooting each other).
* InfantImmortality: Averted in the first and second games, which let you kill children (though doing so is a great way to irreversibly wreck your reputation with the Childkiller title.)
* InstantAIJustAddWater: At least one in each game... ZAX in ''Fallout'', SKYNET (no, not [[TheTerminator that SKYNET]]) in ''Fallout 2'', and [[spoiler:President Eden (also of the ZAX series)]] in ''Fallout 3''. Interestingly, ZAX and SKYNET are mostly benevolent (although it's suggested SKYNET is not to be entirely trusted), although [[spoiler:Eden]] ends up as the game's BigBad.
** At the end of ''Fallout Tactics'', after [[spoiler:defeating a army of cold, merciless robots]] and [[spoiler:exploding the front door of Vault 0 with a nuke]], you came face to face with [[spoiler:the Calculator, a super-powerful AI that's pretty much Instant AI, except you had to add... BRAINS. Human brains, if possible, but rat brains worked as well]]. Some other robots are also powered like that, like the Robobrains, SKYNET and Protectons.
* InsurmountableWaistHeightFence: The constant insurmountable piles of concrete scattered around downtown D.C. that prevent any sort of easy movement through the city are very irritating, forcing the player to use the sewers to get around. Especially annoying, considering similar piles of concrete that have the advantage of not being located at the edge of an area are quite easy to climb. VideoGame/FalloutNewVegas has some particularly lazy examples of this; the overworld is cut into cells to ease loading times, and one can only transit between cells at passes. Unfortunately, someone forgot to tell this to the designers who made the visual landscapes, meaning the Courier is often unable to climb two-degree slopes at the edges of cells. In particularly buggy areas such as the area around Nelson, the Courier can end up several dozen feet off the ground by skimming a cell edge.
* InvulnerableCivilians: In the first two games, all characters were killable by the PC, but were never subject to random deaths by other objects in the gameworld outside of battles that put [=NPCs=] in harm's way, such as the large Regulator shootout in the Boneyard in ''Fallout 1''. Also, [=NPCs=] accidentally hitting (usually shooting) other [=NPCs=] in combat would often cause the injured party's [=AI=] to retaliate, along with other [=NPCs=] on the injured party's computer-defined "team." In a densely populated area such as the Den with many "teams" a few stray bullets or molotov cocktails can easily result in the townspeople all but wiping each other out with no input from the player. Very not invulnerable. [[PassThePopcorn And also amusing.]]
* IWantMyJetPack: Nuclear cars were a big thing in the 50's, and were thought to be replacing gas-powered ones. They obviously didn't work out. The retro-future of Fallout began to gradually phase out gas engines in favor of miniature reactors in [[JustBeforeTheEnd the mid-2070s]], because by that point the world's supply of gasoline was nearly exhausted. This is a major part of the backstory - the Resource Wars that eventually led to the whole nuclear apocalypse were fought over petroleum, and uranium once the world's petroleum was depleted. In the first two ''Fallout'' games nuclear-powered vehicles were extremely rare, with most vehicle wrecks you find being of conventional, non-explodey gasoline-powered cars. Nuclear-powered cars were [[FanWank presumably]] more common on the East Coast because either the factory producing them was closer or they were simply more widely distributed there, although the most likely explanation is simple RuleOfCool.
* {{Jerkass}}: It probably has something to do with the fact that their civilization has been reduced to rubble and every day is a struggle for survival, but even setting aside the various raiders and slavers, there sure are a lot of assholes wandering around. Almost every single person you meet has some kind of chip on their shoulder.
* KarmaMeter: Not displayed on screen, but as a number in your character information in the first two (and abstracted into five terms in the third, each referencing a different amount). It affects NPC reactions, and can cause hostiles opposed to your philosophy to [[InescapableAmbush ambush]] you.
** Hilariously, killing Fiends (violent drug addicts) in New Vegas grants an obscene amount of Good Karma, meaning that wiping out their den in Vault 3 has a very good chance of bringing a Very Evil character to Very Good.
* KillEmAll: In the original game, it's actually possible to personally murder every single living thing in post-apocalyptic Central California, [[spoiler: including the usually-unkillable Overseer at the end of the game.]]
* KillerRobot: Robots in general are fairly homicidal in this series, but special mention has to go to Cerberus, guard dog of the Ghoul city Underworld. He will extol the virtues of his Ghoul masters, then curse the "pansy zombie programming" which prevents him from slaughtering them. If you have the Robotics Expert perk, you can remove his combat inhibitor. HilarityEnsues, since Cerberus by himself can slaughter the entire population unaided in some cases. Of course, he'll try to kill you given the chance, too, but he's not that strong compared to you.
* KnightTemplar: The Enclave, at least in Fallout 2. All mutants must die for the 'true' humanity to rise again. 'All mutants', at this point, is basically all of the surviving humans.
** The Brotherhood of Steel's dogma maintains that they're the guardians of the all the old world's advanced technology. They therefore hoard all the tech they have without sharing, and steal tech from their neighbors to "keep it (the technology) safe from abuse". They help you against The Enclave because the latter are a threat to their technological superiority.
** The Mid-Western Brotherhood of Steel, based in Chicago, are a little better in that they interact peacefully with the tribals around them and help them. They are still a fascistic militant group and their 'interaction' is basically a glorified protection racket "for your own good", but they at least seem intent on including outsiders in building a better tomorrow.
* LampshadeHanging: There's a lot of this, whether it be by [=NPCs=] or by the main character him/herself, particularly the Chosen One from the second game, provided he/she isn't an [[HulkSpeak idiot]].
* LegendaryInTheSequel: From a naive man/woman in a stupid blue jumpsuit, the Vault Dweller's many achievements have made him/her a household name by Fallout 2.
* LethalJokeItem: The [[AChristmasStory Red Ryder Limited Edition BB Gun]]. It does virtually no damage to enemies... unless you hit them in the eyes, in which case it becomes ''the most powerful weapon in the entire game'' and has a near 100% crit rate, regularly resulting in LudicrousGibs even against [[DemonicSpiders Super Mutants]] and [[BossInMookClothing Nightkin]]. It is, however, [[CaptainObvious useless against enemies that don't have eyes]]. The same BB Gun makes it's return in New Vegas. The weapon has an extremely high critical damage multiplier and perfect accuracy, and while hidden, with the right perks, its damage output surpasses everything short of an Anti-materiel rifle with a sneak attack critical.
* LivingLegend: By the end of any given game, the protagonist will have been everywhere, met everyone, changed everything for better or worse, and become a legend. Or maybe you just skipped right to the end, because you can do that.
** The Courier is unaware until ''Lonesome Road'' that they already ''were'' this to the people of the Divide, [[spoiler: and not [[MikeNelsonDestroyerOfWorlds in a good way]]]].
* LivingRelic: Despite the nuclear annihilation and the 200+ years that have passed since then, there are still several characters that serve as living remnants of pre-war America. There are a significant number of pre-War ghouls (most prominently Desmond Lockhart from ''Point Lookout'', Raul Tejada from ''New Vegas'', and Dean Domino from ''Dead Money''), a handful of sentient computers ([=ZAX=], [=SKYNET=], Button Gwinnett (possibly), and [[spoiler: President Eden]]), a few [[BrainInAJar Brains In A Jar]] (Professor Calvert, the Think Tank), and a few pre-war individuals who were preserved in suspended animation (Mr. House, the Tranquility Lane inhabitants, and the prisoners aboard Mothership Zeta). Of them all, most have either adapted to the new world (in the case of the Ghouls), or are cripplingly insane (in the case of Calvert and the Think Tank), with only Mr. House and [[spoiler: President Eden]] really holding onto the vision of pre-war America and trying to restore it in the Wasteland in their own way.
* LookOnMyWorksYeMightyAndDespair: An underlying theme of the game. Especially prevalent in Fallout 3, where you see the ruins of Washington, DC. Several landmarks are crumbling shadows of what they once were. The White House is simply [[NukeEm gone]]. And it's eerie and nearly empty despite a few survivors and a plethora of things (human or otherwise) that want to kill you.
* LuckStat: Puts the L in SPECIAL. Increases your chances at {{critical hit}}s, positive RandomEncounters and all sorts of other nice things. In ''New Vegas'', one dialogue option for characters with high enough Luck lets you successfully ''guess'' a password off the top of your head. [[ThePasswordIsAlwaysSwordfish And it's not even "swordfish"]]...
* LudicrousGibs: Will happen after taking the Bloody Mess perk/trait, [[ExactlyWhatItSaysOnTheTin which does exactly what it says]] to your enemies. A starting-out character with the trait can ''punch'' a hole in a gecko, or kick a rat and make it explode.
** ''In Videogame/{{Fallout 3}}'' and ''Videogame/FalloutNewVegas'', the Bloody Mess perk can actually make corpse looting tedious if you mow down a large number of targets in a small area; you'll likely take a while sifting through the mess.
* MadeOfIron: The hillbillies in the Point Lookout DLC for the third game are ''absurdly'' hard to kill for no explainable reason. The Enclave should ditch their power armor project and just make armor out of hillbilly hides.
* TheManTheyCouldntHang: Allegedly ''Van Buren'' was going to have one as a companion NPC. He is referenced pretty often in ''New Vegas'' when dealing with Caesar's Legion and appears in the Honest Hearts DLC as TheAtoner.
* {{Mascot}}: Both in-world and out-of-world, the Vault Boy - the wavy-haired, perpetually smiling figure in the jumpsuit whose picture accompanies all Skills, Traits, and Perks. In-world, he was the mascot for Vault-Tec Industries. Out-of-world, he serves the same purpose for the series.
* MatchMakerQuest
* MedievalStasis: From 1843 to 1960, there was a world of difference, from technology to culture to politics in the span of 127 years. From 1960 to 2077? Not so much. Still holds true for after the Great War, with over 200 years having passed and very little actual rebuilding being witnessed in places.
** However, this applies primarily to fashions and society: [[RedHerring Communism]] was still the great menace, women were still [[StayInTheKitchen chained to the stove,]] and cars were still curvy and chromed. Bomb-shelter architecture, particle physics, and weaponized viruses (not to mention propaganda-as-mind-control) all made great strides under the PowersThatBe of pre-war America.
* MoneySpider: Mostly averted in that only humanoid enemies drop money. Played straight with centaurs in ''Fallout 3'' though.
* MoreDakka: Everyone loves Miniguns, and you should too. Speaking generally, the best guns in the games are either a minigun of some type or EnergyWeapon of some kind. (See also BeamSpam.)
* MultipleEndings: Yet another staple of the series. TheDevTeamThinksOfEverything is in full effect here.
* MushroomSamba: Vault 106, and the ''Walking With Spirits'' quest in Point Lookout.
* TheMusketeer: Enemy too close? [[DropTheHammer Drop the sledgehammer]].
* MysteriousProtector: the "Mysterious Stranger" perk in 2,3 and New Vegas, with the Miss Fortune Perk added in the last.
* MythologyGag: In ''Fallout'', recruitable NPC Tycho mentions he's a Desert Ranger. The Desert Rangers were the protagonists of ''Wasteland'', the game to which ''Fallout'' is a SpiritualSuccessor. The BigBad of ''Fallout Tactics'' also seems to be a subtle ShoutOut to the BigBad of ''Wasteland''. Also, some Rangers holed up in the Capital Wasteland. As per WordOfGod, Tycho's outfit became the basis of the Desert Ranger Combat Armor, which in itself inspired the IconicOutfit of the NCR Veteran Rangers.
* ANaziByAnyOtherName: The Enclave, due to their autocratic and militaristic rule and their stated goal of wiping out all "mutants" to keep humanity "pure", are frequently compared to NAZIs.
* NecessarilyEvil: Lord Ashur from [[VideoGame/{{Fallout3}} The Pitt addon.]]
* NewOldWest: Certain elements of the Capital Wasteland (mining and 'frontier' type towns, bounty hunters, travelling traders beset by robbers, a heroic (or villainous) drifter, etc.) hearken back to Westerns, but with places like Rivet City or the Vaults, those elements are mixed in with Sci-Fi.
** New Vegas is much more prominent in this. Revolvers and dusters and other parts of cowboy culture are given great focus, and several towns (like Goodsprings in the beginning of the game) heavily resemble the Old West.
* NiceJobBreakingItHero: In ''Fallout 2'' a special random encounter sends you back in time to Vault 13 shortly before the beginning of the first game... where you do a nice job [[StableTimeLoop breaking their water chip]]. You cannot return to your own time without doing so.
* NiceJobGuidingUsHero
* NightOfTheLivingMooks: Subverted. Ghouls are actually the most ''peaceful'' "race" in the ''Fallout'' universe - implied to be because while they may be tough, they're ''really'' not good fighters - although you do very rarely have random encounters with Ghoul bandits and psychotics. They're also immortal unless they die by violence, which provides a strong incentive to avoid it.
* NinjaPirateZombieRobot: The [[spoiler:final boss]] of ''Fallout 2'', Frank Horrigan, is described as a "genetically engineered cyborg psycho secret agent."
* NoCanonForTheWicked: The canon Vault Dweller and Chosen One were both [[TheParagon great inspirers of hope and progress]] throughout the Wasteland.
* NoCelebritiesWereHarmed: In ''Fallout 2'', the Hubologist's "celebrity spokepersons" are named Juan Cruz and Nikki Goldmann.
* NonCombatEXP: The series awards XP for doing non-combat related things, which may bypass combat altogether, such as lockpicking, hacking and persuasion.
* NonhumanSidekick: Every game has at least one.
* NonIndicativeName: The Science skill mostly just boils down to knowing how to use a computer, with a bit of hacking thrown in on occasion.
* NonstandardGameOver: If you sell out your people to the first game's BigBad, and if you attack anyone in the starting village in the second. In the third, you will get one for revealing the code to the purifier to TheDragon.
* OneHitKill: In Fallout 1 and 2, if a targeted shot rolls an extremely high critical (101+ ), it will result in an instant-kill, even if the actual damage is not enough to fell the enemy. This can happen only on targeted attacks to the head, torso, or eyes.
* OneStatToRuleThemAll:
** Intelligence across the series, since higher Intelligence means more skill points per level, unique dialogue options with characters that unlocks hidden quest paths, and it increases the Science and Repair skills, also very useful for gameplay.
** In the first two games, Agility. It increases Action Points to allow more actions each combat round, and increases ''all'' combat skills along with a handful of non-combat skills too. No longer the case in the Bethesda-era games, where Agility is tied to much fewer skills and [=VATS=] is optional for combat.
* OnlyKnownByTheirNickname: Played with for the player characters across the series. The first game never gave you a name or nickname, but games since have decided the player character of the first game is "The Vault Dweller". The second game, you're "TheChosenOne", but no one outside your tribe refers to you this way and will be amused if you say that it's your title. ''Fallout 3'', Three Dog dubs you "The Lone Wanderer" but no one else uses the term. ''New Vegas'' flips this, you're "The Courier" to everyone ''except'' Mr. New Vegas, who just refers to you as an anonymous civilian contractor or courier. Both Bethesda era games occasionally include the option for you to mention your name in dialogue, but for obvious reasons (ie, all [=NPCs=] are voiced) no one will ever refer to you by name.
* OppressiveStatesOfAmerica: The pre-War United States of America was not pretty. The infrastructure of America had collapsed due to the resource shortages (id est; food, fuel, and material) while unemployment was skyrocketing. The Government responded by becoming a police state and by trying to scapegoat their problems on Communists, then brutally cracking down on anyone who spoke out against the government; by claiming they were one. Arrests, "Re-Education," and in some cases outright murder followed as the Government tried to keep the population in line. For example the New Plague, which the government claimed was a "Social Disease," and that one of the symptoms was new and radical ideas such as Socialism. It wasn't, it was a disease so terrible that the first ever national quarantine was declared. Before long the government had given up trying to cure it, (Instead using the research to develop super soldiers.) and decided to use the paranoia created by its spread, as a cover in order to break up assemblies and register people. Eventually Civil Liberties became virtually non-existent. In one example the commanding Officer of the Hopeville missile base, Commander Devlin, had a hippy protest group arrested and sent off for human experimentation, claiming it was giving them "The White Hot Rage of Capitalist Justice." These tactics made things worse, and by the end of 2077 the United States was on the verge of a massive civil war.
** [[spoiler: This was done because the éminence grise of the federal government (The Encalve) realized it was likely only a matter of time until total nuclear war occurred, and knowing that the common man would not survive it they believed that they alone were worthy of re-colonizing the planet. Originally their focus was to find another planet to live on, however they could not succeed in this goal and decided to re-colonize the planet they were already on.]]
* TheOrder: The Brotherhood of Steel, deliberately modeled after medieval knightly orders.
* PacifistRun: Possible in all the games, to an extent.
* PaddedSumoGameplay: The first two games have this issue in the very late game, where opponents with power armor are almost incapable of doing even a single point of damage except in critical blows, so combat basically boils down to watching “0 Points Of Damage” bullets bounce off each other until “Critical Hit for 999 HP” obliterates somebody.
* ThePennyfarthingEffect: 1 and 2 have this in spades. Most prominently, you won't get any description of a usable object in the environment or even any indication that it's usable without first switching to the "look" cursor.
* {{Planimal}}: Spore plants, one of which becomes sentient.
* PlasmaCannon: Plasma weapons are high-end energy weapons. In the first two games, the Glock 86 Plasma Pistol and Winchester P94 Plasma Rifle (stretching the definition of rifle, being held like a heavy weapon) filled the role. In Fallout 3, a completely new style of plasma weaponry was introduced, using an RaygunGothic styling and visibly showing the plasma arcs in the firing chambers. This latter style was retconned/reconciled in Fallout New Vegas as being a more standard-issue-practical plasma weapon compared to the pre-Fallout 3 versions that never made it past prototyping before the Great War. In game terms, the Fallout 3-style weapons were lower-tier, and the (renamed) Fallout 1-style weapons were higher-tier. In New Vegas, you can even find the SuperPrototype of the Fallout 3-style rifle, the Q-35 Matter Modulator.
* PostPeakOil: Before the Great War, peak oil was the cause of the Resource Wars that devastated both Europe and the Middle East. Gas prices reached up to $1450.99 per gallon for regular. The United States (and possibly China) were only saved by going to an all-nuclear society, while the rest of the world ended up collapsing. It was all made moot however, when everyone started to sling nukes at each other.
* PoweredArmor: Iconic to the series. Some variant of it is always the best armor in the game--whether Hardened Power Armor in ''1'' or Advanced Power Armor Mark II in ''2''--providing excellent protection from firearms and environmental hazards as well as a significant strength boost. Worn by both the Brotherhood of Steel and the Enclave.
** In the third game, however, it loses a little of its luster as all forms of it excluding the [[InfinityPlusOneSword Infinity Plus One Armor]] decrease Agility, which is the primary statistic for VATS (unless you hate VATS, which just makes that a null issue). On top of that, other armor types nearly match the T-51b in protection, while being far lighter. And it still doesn't do you any good in the end. The ''Operation Anchorage'' DLC fixed this unintentionally with the glitched Winterized T-51b, which is essentially indestructible in addition to having the highest damage reduction available.
* PowerFist: InfinityPlusOneSword for characters using the Unarmed skill; can be upgraded to a Mega Powerfist in some games.
* PresidentEvil: [[spoiler:BigBad]] U.S. President Richardson in ''VideoGame/{{Fallout 2}}'', who also serves as President Exposition.
* PressXToDie: Several examples. In ''Fallout'', a nuke timer can be set to 30 seconds. Suffice it to say you're going to get a front-row seat.
** Tellin Colonel Autumn the Project Purity code in ''VideoGame/{{Fallout 3}}'' results in him [[YouHaveOutlivedYourUsefulness shooting you]].
** ''VideoGame/FalloutNewVegas'''s ''Dead Money'' DLC has two of these; either [[SealedRoomInTheMiddleOfNowhere locking yourself in the casino vault]] by reading a message [[SchmuckBait you were warned several times about]], or [[WeCanRuleTogether joining forces with Elijah]] to wipe out the Mojave with the Cloud.
* PreviousPlayerCharacterCameo: The player character from ''VideoGame/{{Fallout|1}}'' reappears in ''VideoGame/FalloutBrotherhoodOfSteel'' games as an NPC.
* PunchedAcrossTheRoom: Requires a ''very'' good damage roll if fighting barehanded, but it is possible to hurl someone a fair distance (a couple hexes, depending on damage, in the first two games) if you do more than 10 points of damage in melee. The sledgehammer weapons greatly increase the distance traveled.
* PunchClockVillain: One recurring theme throughout the series regarding the major evil organizations; the leadership is ruthless, and the rank-and-file have their share of True Believer fanatics and sadists, but many of them are actually just regular joes who think they're doing the right thing, simply obey because they've never known of any other alternative, or are trying to make the best of a bad situation. Members of the BigBad faction of one game often show up in later games as friendly supporting characters, having mellowed out in the interrim after the downfall of their leaders.
** Especially seen in the Enclave Remnants in New Vegas where all of them just wanted what was good for America.
* PuttingOnTheReich: The Enclave are very similar to Nazis, goals and methods wise.
* RadiationImmuneMutants: Ghouls, who even heal from radiation.
* RagnarokProofing: Averted in the first two games, which pretty much assume complete destruction of every identifiable landmark that hasn't been constantly maintained (one location, appropriately called Junktown, is apparently constructed entirely out of scrap wood, stone, and metal).
* RandomEncounters: Happens whenever you travel across the map screen in ''Fallout'', ''Fallout 2'', and ''Fallout Tactics''. Not all random encounters are hostile though, some are even beneficial, and with a high Outdoorsman skill you can circumvent most of them.
* RareGuns: Desert Eagle, G11s, the automatic shotguns of ''Fallout 2,'' and several others from the list.
* RealIsBrown: Very much so.
* RecurringElement: Harold.
* RecycledInSpace: The Enclave are essentially Nazis IN AMERICA.
** Caesar's Legion are Romans IN THE WASTELAND.
* TheRemnant: Where to start? You've got the remnants of the Master's Army and the Enclave (the remnants of the éminence grise of the US government) in ''Fallout 2'' and ''Fallout 3'', as do the game's ghoulified Chinese soldiers on U.S. soil, still waiting for the war to end.
** In ''New Vegas'', you get the Enclave Remnants, making them the remnant of the remnant.
* RetroUniverse: Fallout America is an amalgam of all the decades of the ColdWar, as well as the SciFi Produced during those decades. TheForties give the setting its wartime propaganda, urging you to buy Victory Bonds. TheFifties give it their Pre-War fashions and car designs; Fifties SciFi gives it ''nuclear cars'' and the styling of its robots. TheSixties give it the use of the word "hippies" (in Fallout 3) and anti-war graffiti (all over Hidden Valley in New Vegas). TheSeventies give it the punk fashion of the raiders and the oil crisis. TheEighties give it computers that look like Commodore 64s. The post-war civilizations also show elements of the Great Depression and 19th century frontier times.
* RobotBuddy : Skynet and K-9 in Fallout 2, RL-3 in Fallout 3, ED-E and Rex (technically, it's a [[BrainInAJar cyborg dog]], but still...) in New Vegas.
** Also in New Vegas, you have Yes Man, who helps you take over New Vegas for yourself if you help him and is [[{{Keet}} always cheerful and friendly]].
* RomanceSidequest: One of the few Western RPG tropes not used in the series. In ''Fallout 2'' you could get married, but it was a ShotgunWedding with a one-night stand treated mostly as a joke, and you couldn't have any meaningful interactions with your spouse after the marriage anyway. An optional romance subplot was planned for ''New Vegas'' but it was ultimately scrapped.
* ScavengedPunk: Much of the weapons, equipment, clothing, armor, and at least one entire city are made of Pre-War junk that's distinctly AtomPunk in style.
* ScavengerWorld: It's a post-apocalyptic series, it goes without saying. That said, it's not like scavenging is the only thing people do, and there are several communities dedicated to rebuilding and creating things anew. In ''Fallout 2'' and ''New Vegas'', many parts of the wasteland have become quite civilized again.
* SchizoTech: People before the war had AI, antigravity, robots, computer-assisted driving, pocket computers, satellite-based weapons, and powered armor, but color TV and mobile phones? Hell, they weren't miracle-workers. Justified somewhat in that pre-War society is supposed to represent the RaygunGothic image of the future popular in the 1950s, not necessarily the future of ''our'' world.
* SetAMookToKillAMook: Plenty of opportunities to do this in all the games since they keep track of the multiple factions.
* ShoutOut: Too many to count. Everything from ''Creator/MontyPython'' to ''Franchise/StarTrek'' to half the post-apocalyptic science fiction ever made.
** Most of the special encounters are ShoutOut material.
* ShownTheirWork: ''Fallout 1'' featured a detailed description of cell division, and how a mutagenic artificial virus interfered at the anaphase stage. In many ways, the result of this interference is the single most ''fantastic'' element of the story; everything else follows.
** Myron's explanation for how Jet was discovered, although somewhat fantastical, is quite complex.
* SicklyGreenGlow
* SkippableBoss: [[spoiler:The Lieutenant and the Master in the first game, General Jing-Wei and Colonel Augustus Autumn in the third. All of them could be skipped by either a stealthy or a diplomatic approach - and only diplomatic for the last two. New Vegas brings in Legate Lanius, capable of surviving multiple antitank rounds to the forehead, who can be convinced to step down with a maxed-out Speech or Barter skill.]]
** You can potentially do this to [[spoiler: Legate Lanius]] in ''New Vegas''. For the DLC, you can with a bit of work skip fighting [[spoiler: Father Elijah]], [[spoiler: the Think Tank]], and [[spoiler: Ulysses.]] The first is a bit tricky, though, as you have to [[spoiler: both succeed at a skill check to convince him to enter the vault, and then sneak out of the vault without him seeing you, ''and'' get to the elevator before he closes the forcefields. Screwing up at any point activates the forcefields and forces you to fight Elijah.]]
* SlidingScaleOfIdealismVersusCynicism: Slightly towards idealism, unbelievably. Yes, the world has burned in nuclear fire and is host to all manner of unsavory characters and vicious animals who will kill you or worse. But civilization has endured, is rebuilding, and there is still goodness and virtue in the hearts of some. And if you play a good character, the good will eventually overcome the evil. There's a reason why tropes like EarnYourHappyEnding exist.
* SlidingScaleOfTurnRealism: Action by Action by virtue by the action point system.
* SlidingScaleOfUndeadRegeneration
* SocialDarwinist: Capital Wasteland Super Mutants. One of their battle quotes is even "WE ARE THE FUTURE!" Considering they have no reproductive ability and can only reproduce by turning humans into more Super Mutants, this seems unlikely... but they are pretty stupid.
** This is actually the key to an alternate way to win ''Fallout''. If you find proof of their sterility and tell The Master about it he'll kill himself, making this a good option for nonviolent characters.
* SoloCharacterRun: Extremely common throughout the series due to ArtificialStupidity. In VideoGame/{{Fallout 1}}, companions [[CantCatchUp did not level up, could not change their starting armor]], and were generally liabilities due to friendly fire and obstructing doors or corridors. Improved somewhat in the sequels.
* SpiritualSuccessor: To the 1988 game ''[[http://en.wikipedia.org/wiki/Wasteland_(computer_game) Wasteland]]''.
* StealthRun: Possible in all three games.
* StockFootage: One piece of promotional art for [[http://www.bravenewgamer.com/wp-content/uploads/2010/11/fallout-new-vegas_22.jpg New Vegas]] was just concept art for [[http://fallout.gamepedia.com/File:Stripmall_m.jpg Paradise Falls]] from Fallout 3, with the sign in the background changed.
* StuffBlowingUp: Each DefinitelyFinalDungeon inevitably ends in this, in every game. In ''Tactics'', [[spoiler:you choose whether it does or not.]]
** In ''New Vegas'', [[spoiler: there is neither a definitive BigBad nor a definitive DefinitelyFinalDungeon, so instead you get Ulysses, who is a {{Foil}} to the main character, and the fact that he is willing to nuke all of civilization back to the stone age marks him as one of the main antagonists of the game. Even if you stop the launch, the nukes still go off.]]
* SuperSoldier: The original and current point of creating Super Mutants, Deathclaws, and Power Armor. This was the US's hat before the war.
* SurvivalistStash: All over the place, with varying degrees of loot. Some have their locations hinted at by notes or dialogue, and some are just lying in the middle of nowhere. And, of course,you're likely to stockpile a few of your own once you start to [[CriticalEncumbranceFailure exceed your encumbrance limit]].
* TakeYourTime: Averted in the first game. Played straight in all subsequent games.
* TalkingTheMonsterToDeath: A very common way to deal with the FinalBoss and/or BigBad is to talk your way out of the fight, or you can avoid it entirely.
** In ''1'', the Master can be talked into destroying himself if you convince him his plan will fail. TheDragon, the Lieutenant, can be avoided by self-destructing the base.
** ''2'', you can talk the MadScientist who is responsible for the BigBad's scheme into sabotaging it. The BigBad will happily converse you with, but conversation goes nowhere and he's not a fighter so he doesn't attack you unless you strike first. You also set their base to self-destruct, ensuring his death anyway. In a rare case for this series, the FinalBoss ''cannot'' be talked down, and this is almost lampshaded by allowing you to ask "can't we talk this over?" and the villain laughing "we just did".
** ''3'', Autumn can be talked into walking away by convincing him he fights for a lost cause.
*** The add-ons: ''Operation Anchorage'' lets you convince the final boss to kill himself. ''The Pitt'' lets you talk one of the two villains (depending on quest options) into fleeing, the other must die. In the other three add-ons, the final villain must be killed.
** ''New Vegas'', you may face one of two final bosses, or both. Both can both be talked into standing down without a fight. The BigBad of the Legion, Caesar, must be killed, but he's a BonusBoss and his death is not demanded by the story.
*** The add-ons: ''Old World Blues'' lets you talk the villain into reforming, ''Dead Money'' lets you snare the villain in a DeathTrap without fighting him, and ''Lonesome Road'' lets you talk down the final boss. ''Honest Hearts'' plays with this by [[spoiler:having Joshua Graham subdue the villain, Salt-Upon Wounds, in a cutscene, and you can either talk down Joshua into letting him live, letting him fight for his life, or just let him kill him.]]
* TechnoWreckage: The abandoned vaults, the Glow and the Sierra Army Depot.
* TrailersAlwaysSpoil: The box for the Fallout Trilogy has a screenshot of the final boss battle for Fallout 2.
* TroubleFromThePast: Half of the problems in the entire series are leftovers from the past, either in the form of radiation, old world machines, or other leftover messes.
* UndergroundCity: The Vaults were designed to function as these. Ghoul communities tend to be found in subterranean locations, such as Necropolis located in the ruins and sewers of Bakersfield, as well as Underworld in the Capital Wasteland.
* UniversalAmmunition: All guns with the same caliber take the same ammunition.
* UselessUsefulSpell: There are a few traits and perks in the series that are theoretically awesome but useless in practice, such as the third game's 'Nuclear Anomaly' perk (funny, and occasionally handy, but it doesn't discriminate between friend and foe and cannot be turned off), the first and second game's 'Skilled' and 'Night Person' traits and 'Presence' perk, and a few others.
** Fast Shot (-1 AP to shoot, no aimed shots) + One Handed (Bonus to hit with one-handed weapons, penalty with two-handed) is a fun combination for role-playing purposes and [[SelfImposedChallenge not using Gifted]]. Pretty viable in ''Fallout 2'' with some Melee/Unarmed skill and gets better once you get a [[HandCannon .44 Magnum]].
** Computer Whiz and Infiltrator in Fallout 3 and New Vegas. Respectively allows you to re-hack a computer if you locked it after failing to hack it and to pick a lock you've broken by trying to force it. Useless for two reasons : you can leave the computer and retry anytime as long as you didn't lock it and forcing the lock is an option.
* UtopiaJustifiesTheMeans: The MO of quite a few villains throughout the series.
* UniverseBible: available [[http://fallout.gamepedia.com/Fallout_Bible here]] among other places.
* TheVeryDefinitelyFinalDungeon: Five of them:
** ''Fallout'': [[spoiler:A big Cathedral in the middle of the ruins of Los Angeles inhabited by strange cultists and a shadowy atmosphere. Bellow, there is a dark Vault filled with Super Mutant Nightkin elite troopers, mad scientists, mutated aberrations, cultists and crazy FEV-induced psykers. The walls are full of a grotesque biological goo that looks strangely alive. At the end of your way, you have to pass a corridor where your nemesis starts blasting you with his immense psionic powers. At the end, you meet what can be accurately called the strangest being of the wastelands: insane, super-intelligent, grotesquely mutated]]. There's also [[spoiler:an old military laboratory in the remote badlands west of Vault 13, guarded by strong mutant soldiers and robots. The base is brightly-lit, yet the atmosphere is dense and shadowy. In the depths of the base, big vats of bubbling green fluid contains, depending on the point of view, either the key to the evolution of the human race, or its eventual demise.]]
** ''Fallout 2'': [[spoiler: The Enclave Oil Rig, the stronghold of the extremely well-equipped remnants of the éminence grise members of the United States Government, a massive fortress significantly larger than any other settlement or dungeon, populated by an army larger than all other armies combined, consisting of incredibly tough PoweredArmor-wearing soldiers loaded with the best weapons in the game and lots of stimpaks. Indeed, unless you're an ''insanely'' tough, completely combat-oriented character, your only viable means of getting through is to [[DressingAsTheEnemy disguise yourself by wearing one of their own armored suits]] and sneaking past everyone.]]
** ''Fallout Tactics'': [[spoiler: Vault 0. For most of the first half of the game, you are just expanding the Brotherhood's influence, crushing rebellions, killing raiders, so on and so forth, but then you run into the Super Mutants, who were the reason the Midwestern Brotherhood was sent over the mountains in the first place. But even they're not the true enemy- they were merely mobilizing to fight an even more significant threat- robots, centered around Vault 0, and towards the end of the game you move further and further into Colorado and into the mountains, until you start seeing real snow (unusual in a setting without much weather) and finally end up getting into the heavily-guarded Vault 0... by blasting it open with a nuke. From that point on, all bets are off, and you can't go back to home base...]]
* VideoGameCrueltyPotential: You can be a sick, sick bastard if you so desire. Pimping your wife and then divorcing her, becoming a slaver, causing gang wars, murdering children... if you count post-end-of-game results, your actions can cause entire cities to fall apart.
** A minor, but rather poignant, bit of cruelty is convincing Moira to give up on her Wasteland Survival Guide. Not only is this considered evil, but it gives you a perk called Dream Crusher and forever dampens her ordinarily cheery attitude. There are benefits, of course, but they really went out of their way to make you seem like a bastard for doing it.
** In ''Broken Steel'' [[spoiler: You can wipe the Brotherhood HQ right off the map, kill off any stragglers, and get a special Magnum if you do]].
** Mid- to endgame main quests in ''New Vegas'' requires you to screw over each main faction except the one you favor, and it's quite possible to have them think you're working for them up until the moment of betrayal. It's quite easy (and historically appropriate) to visit Caesar for a negotiation and stab him to death, and Mr House, well... [[spoiler:given what a pitiful creature he's become, it's hard not to feel like a heel for ending his dream.]]
* VideoGameCrueltyPunishment: If you're a slaver, childkiller, or just an evil, evil bastard, a lot of folks won't take too kindly to you.
* VillainousLegacy: Non-character example. The BigBad of the first game, TheMaster, was using the Forced Evolutionary Virus to mutate humans. The villains of the second game excavated the ruins of his lair to retrieve the FEV for their own uses, and the villains of the third synthesized their own version for their plan as well.
* VillainProtagonist: Just one of the many possible playthroughs for the player character in ''Fallout''.
* WasOnceAMan: Every ghoul and super mutant you encounter was a human once.
* WastelandElder: A lot of towns have them. This includes [[TeenageWasteland Little Lamplight]], whose "Elder" is about 12.
* WeCanRuleTogether: The Master, President Eden, and Caesar all make similar offers to the player character. The Master is actually good for it, while Eden's plan will get you killed, and Caesar doesn't exactly have the best track record of keeping his promises (especially if you're playing a female character, given Caesar's view on the place of women in society).
** In ''Dead Money'', ''the player'' can make this offer to the BigBad, Father Elijah, but only if they have a negative relation with the [=NCR=], whom Elijah wants to overthrow.
* WebGames: Bethesda created a demake of ''Fallout 3'' for browsers. The graphics are 8-bit style and similar to the early ''DragonQuest'' games. The demake is currently only in Japanese, but it's fascinating: http://www.bethsoft.com/jpn/fo/fo_quest/index.html
* WeHaveReserves: The New California Republic defeated the Brotherhood Of Steel because the Brotherhood, being an elitist order, had too few members to conscript for troops. For years, they fought the war under the assumption that their technological superiority gave them the advantage, until it became clear that they were doomed because they could not replace their troops fast enough.
* WeirdScience: The ''Fallout'' 'verse runs on 50-style B-movie '''SCIENCE!'''
* WellIntentionedExtremist: Most major villains tend to be these (or at least, they think that they are). The Vault 101 Overseer is one as well.
* WhatCouldHaveBeen: Originally, ''Fallout'' was going to be based on a licensed version of the paper RPG GURPS, from Steve Jackson Games, and would have published under the name ''Vault 13: A GURPS Post-Nuclear Adventure''. But due to disagreements, including Steve Jackson disliking the appearance of Vault Boy on the character creation screen, and the execution of the insurgent from the intro, the deal was called off. Instead, Black Isle thought up the SPECIAL system, which has been used in every Fallout game ever since.
* WhatsAnXLikeYouDoingInAYLikeThis
* WorldOfBadass: Absolutely! The player and their companions each game count as a OneManArmy unto themselves, racking up hundreds of kills on an average playthrough. In a world where your little village could get overrun at any time by super mutants, feral ghouls, slavers, raiders, mutated animals, or power-armor clad extremists, not to mention that just being able to feed yourself for the day and go to sleep on a bed are luxuries many do not have, and just being able to survive to old age is a test of strength and will of anyone in the wasteland.
* AWorldHalfFull: The series in general. Yes, its a post apocalyptic wasteland, but the remaining inhabitants are more or able to get through the day. Of course, playing a Good character makes it count even more.
* WretchedHive: New Reno, The Den, Paradise Falls, Evergreen Mills, The Pitt, Nipton [[spoiler:before the Legion, anyway]].
** Paradise Falls is so bad that its the only town you can completely massacre (preferably with Lincoln's hat and Repeater for extra irony) with absolutely ''no'' repercussions.
* YourPrincessIsInAnotherCastle
** Inversion - while searching Vault City's database for your vault in Fallout 2, your character will notice a Pip-Boy hole if his/her Perception is above or equal to 7. Shoving your Pip-Boy in will give you the location of nearly all the locations. (Normally, finding the vaults would be an ardous task with several middle men involved.)
** Played straight early in Fallout 1, [[spoiler: when you discover that Vault 15's water-purification chip is utterly inaccessible.]]
* {{Zeerust}}: The surviving pre-apocalypse architecture and technology is highly reminiscent of '50s Pop Art: complete with muscle cars, vacuum tube computers, and tin-can robots. Background material establishes that America (and by extension, the world) never really moved beyond the 1950's in terms of values. There was no 60's revolution, no 80's technological shift, nothing like that at all. As a result, even though the world "ended" in 2077, culturally, it hadn't progressed a bit.
