->''"Thugs-4-Less! Pay for six hits, and the seventh is free!"''
-->-- '''[[NoNameGiven Thug Leader]]''', VideoGame/RatchetAndClankGoingCommando

In various forms of fiction, it is terribly common to have various criminal organizations floating around with a single purpose in life: [[ProfessionalKiller causing death to others]]. It is often called [[WeirdTradeUnion The Assassin's Guild]], but it could appear under any number of other names or in any number of settings. Their goals for this vary. It's often simply for money, but it could just be a group that enjoys playing politics. In that case, there's some overlap with the AncientConspiracy, except they're not that old ... and not that big.

Sometimes, Murder, Inc. started as an organized crime group that came under new leadership and started indulging in other, darker (and probably less profitable) hobbies, such as the [[KickTheDog killing of puppies]]. In that case, they probably go by a modern, [[TheMafia Mafia]]-esque name. Frequently and regardless of origin, they have a large code of by-laws that makes one wonder how they do anything without six months' advance notice.

Indeed, there's often overlap between Murder, Inc. and other groups. Often, what makes Murder, Inc. ''different'' from any other [[TheSyndicate Organized Crime Syndicate]]/terrorist front/SecretPolice is the fact that their strength comes not from their numbers or their training, but their reputation. Most such groups could, in fact, really consist of ten competent people and it wouldn't hinder their operations too much. Or two--don't forget [[Literature/{{Neverwhere}} the Old Firm]]. They're feared as the ones that "take people" who are "never seen again." Usually people that [[DeadlyEuphemism "cause problems" that need to be "solved." Capisce?]]

In less contemporary settings--far past or far future--they are the frequent source of TrainingFromHell (and, if their membership is large enough, TheSpartanWay).

In some cases, Murder, Inc. might even be a force that will assist the heroes. But they should never be trusted. It's kind of like trying to beat someone to death with a rattlesnake; deadly, effective, and very, very stupid. However, if a single character [[DefectorFromDecadence leaves this group]], they will be your friend forevermore, possibly becoming the SixthRanger.

There are more pragmatic evils out there. Why kill people when you could be doing something else? Why, for fun and profit, of course! "[[ForTheEvulz For fun]]" usually entails that the group sees murder as an art form of one sort or another (like the BloodKnight you never see coming). "For profit" usually invokes images of the League of Extraordinary Hitmen (tm). Sometimes, what keeps such a group together is a slavish devotion to their leader, who will serve as TheDragon. First glance would indicate Murder, Inc.'s leader would be a good [[TheManBehindTheMan Man Behind the Man]]. Unfortunately, TheReveal is usually too foreshadowed to be useful: after all, if every person on the street fears them, it's not surprising when they turn out to be the BigBad. One can still play it that way, but don't expect the audience to be surprised.

These groups are typically composed of {{Professional Killer}}s, unless this trope is being played for laughs. More comedic examples often operate like a WeirdTradeUnion. May be either ALighterShadeOfGrey, or darker.

The TropeNamer is [[http://en.wikipedia.org/wiki/Murder,_Inc a gang that mainly did killings for Lepke Buchalter and the National Crime Syndicate from the 1920s through the 1940s]], dubbed Murder Incorporated by journalists, aka the Brownsville Boys. They also hired their men out to other mobs. What set them apart was, unlike hitmen who worked on a per-contract basis, they were ''salaried'' and had a benefits package.

Please note that Murder, Inc. isn't always [[EvilInc evil.]] They don't tend to let [[TrueNeutral codes of morality]] get in the way of their [[OnlyInItForTheMoney business model]]. [[note]](Sometimes...)[[/note]]

Compare with PrivateMilitaryContractors, which has similar functions with employees acting as HiredGuns, but is often "legal" compared to the criminal MurderInc ([[CorruptCorporateExecutive not that they're above engaging in dodgy business practices either...]])



[[folder:Anime and Manga]]
* The Red Dragon Syndicate in ''Anime/CowboyBebop'' was always called that, but became much more...uh...[[MeaningfulName vicious]] as time passed. Eventually, their full-time job seemed to be killing people and antagonizing the main characters. The people that the organization was seized from were very opposed to this, and even said the organization wouldn't survive long like this.
* The various ninja villages in ''{{Naruto}}'' are partly this, but are primarily mercenaries who will perform any task for the right amount of money. None of the main characters actually perform assassinations, such tasks being reserved for high ranking individuals. None of the villages are explicitly 'evil' ([[spoiler:except Orochimaru's]]), but are mostly considered enemies of each other.
** Kakashi is a main character and he used to perform assassinations, and may stil do so if not as often. The rookies later own devise their own assassination attempt [[spoiler: against Sasuke]] and in the Grass Country arc the plot revolves around intercepting an Akastuki spy in the Sound village with the intent that his info. can be used to draw up plans to assassinate Orochimaru; this ran simultaneously with a secret plan to [[spoiler: kill Sasuke]] by new member Sai, on orders from ROOT, for whom he had already carried out numerous killing missions.
* The Black Organization of ''Manga/DetectiveConan''. They also deal with drugs and illegal weaponry as well.
* The [[SortingAlgorithmOfEvil Gung Ho Guns]] in ''Manga/{{Trigun}}'' are the murderous minions specifically of the BigBad, selected for their power and willingness to slaughter people, up to and ultimately including ''[[KillAllHumans everybody]]''. In the manga, however, some slots in the Guns are explicitly filled from the ranks of [[ProfessionalKiller The Eye of Michael]], which is one of these that fronts as a Christian church and has its roots in a plant worshiping cult. They therefore tune in to the AncientConspiracy part of the trope. The arrangement is useful to [[BigBad Knives]], because it means if one of these minions dies off there's already a contract in place to bring in a replacement.
** [[spoiler: Wolfwood is one of them, of course. They adopted him around age twelvish and subjected him to horrible experimentation and TrainingFromHell, and he's got subversive goals, but he's very much what they made him.]]
*** In fact, he took advantage of the 'auto-replacement' feature to shoot his [[EvilMentor teacher]] and infiltrate the Guns.
** Anime Chapel the Evergreen, Chapel-with-an-apple, is not shown to be from one of these. He could at least as easily be someone's pet assassin who took on an apprentice and then later fell in with [[TheDragon Legato]], although the information is sparse enough it could go either way.
*** The sense of honor anime Chapel ultimately shows ("the cornered mouse will attack the cat") does not fit with the frenetic nihilism that seems to be in fashion in the Eye, although that might just be Razlo being AxeCrazy, Livio being beyond the DespairEventHorizon, and Master C being crippled and out for revenge.
* Broadly speaking, the Hell Correspondence from ''Anime/HellGirl'' is this in a supernatural, DealWithTheDevil context. They'll instantly whisk anyone you don't like to Hell, but the price is your own soul (after your natural death).

[[folder:Comic Books]]
* The League of Assassins from Franchise/TheDCU.
** The DCU also has the Council of Spiders, a [[{{Motif}} spider-themed]] group of elite assassins that appear to be a subgroup of the League. Their membership includes poisoners, martial artists and a guy with [[MultiarmedAndDangerous six extra arms]]. He can ''[[GunsAkimbo oct]]-wield''.
* Marvel has the Assassins Guild. They were introduced in ''Gambit #1'' and mostly appear in the ComicBook/XMen-related books. They've recently returned as antagonists of the ComicBook/ScarletSpider.
** There was also ''ThePunisher: Assassin's Guild'', featuring another such organization. Oddly enough it had the Punisher ''teaming up'' with the guild.
* There was an organization named Murder Inc. in the MarvelUniverse (Partly based on the real life Murder Inc.) in the 1940s, that would take in homeless men, force them to sign life insurance policies, then collect on the policies after murdering them.
* Koroshi, the assassin's guild from ''ComicBook/UsagiYojimbo''.
* In the ''ComicBook/SinCity'' comics, the Colonel runs an organization of elite assassins.
* In ''{{ComicBook/Fables}}'', [[spoiler:Peter Piper's wife, Bo Peep,]] was a member of such an organization in their Homeland, after the Adversary invaded.

* The Assassins' Guild of Ankh-Morpork, and especially its School, are greatly expanded upon in the ''Literature/{{Discworld}}'' fic written by A.A. Pessimal. Assassins who are barely there in the canon become [[AscendedExtra Ascended Extras]] and get full bios and [[Fanfic/NatureStudies stories to themselves]]; the workings of the School are currently being described in ''[[https://www.fanfiction.net/s/10383608/1/The-Prospectus The Prospectus]]''.

* The creation of such a group, to prevent overlapping contracts, is a major plot point in ''Film/GrossePointeBlank''.
* Two such organizations collide in ''Film/MrAndMrsSmith2005''.
* The Deadly Viper Assassination Squad of ''Film/KillBill'' infamy.
* The Fraternity in ''Film/{{Wanted}}''.
* ''Film/TheAssassinationBureau'', based on the unfinished novel ''The Assassination Bureau, Ltd.'' by Creator/JackLondon.
* In ''Film/TheParallaxView'', the Parallax Corporation seems to be this, whether or not it was a secret government front.

* ''Literature/{{Discworld}}'':
** The Assassins' Guild of the great city of Ankh-Morpork, whose motto is "''Nil Mortifi Sine Lucre''": "No killing without profit", is at once a parody and a lampshading of the trope. The Guild is legal, its head is an influential public figure, and it is common for nobles to send their children to its excellent fee-paying school. The Guild will take political actions for the good of the city, and will even enforce their monopoly on assassination by hunting down murderers. Assassins themselves abide by several rules, including that they always wear black, even when this is detrimental to any attempt to be inconspicuous, and especially that they're not allowed to kill people unless they are paid to do so, and they cannot kill the defenseless. Of course, anyone rich enough is automatically considered able to defend themselves by hiring someone else to protect them.
--->'''Dr. Cruces:''' No, we do it for the money. And, because we above all must know the value of a human life, we do it for a great deal of money.
** There is a Klatchian ([[FantasyCounterpartCulture read Arabic]]) assassination group, the drug-using Hashashin, resembling accounts of the original Assassins (Hashishim). However, descriptions of the Hashashin are sometimes parodic; apparently, they kept giggling at the way light reflected of their knives, swaying to music, and falling over. In ''Jingo'', as Ankh-Morpork goes to war with the Klatch, Vetinari notes acidly that the Guild's boast of being so good that the Klatchians send their children there really means that Klatch's assassins know Ankh-Morpork's methods, have refined their ancestral skills, and have a working knowledge of the city's layout.
** The New Firm: Mr. Pin, the brains, and Mr. Tulip, the muscle (with a bad chemical habit and a deep appreciation for antiquities). Aside from referencing Misters Croup and Vandemar, some of their dialogue also echoes Jules and Vincent of ''Film/PulpFiction''. Mr. Tulip's purse says "Not A Very Nice Person At All," which says it all, really.
* The Hashishin are identified as the ([[UnreliableNarrator possible]]) forebears of the Illuminati in the ''Literature/{{Illuminatus}}!'' trilogy, reflecting assorted flaky real-world conspiracy theories.
* ''Literature/{{Dragaera}}'': The Right Hand of the Jhereg is essentially a fantasy mafia, with assassinations being quite common both within the house and out.
* ''Literature/TheReynardCycle'': The country of Glycon has a famed [[WeirdTradeUnion Assassins Guild]]. The majority of expatriates from their country are freelancers killing people for money.
* ''Literature/ASongOfIceAndFire'' actually features multiple Murders Inc.
** The Sorrowful Men of Qarth will always say "I am so sorry" right before they kill you.
** The Faceless Men of Braavos are {{Warrior Monk}}s who worship death as a universal force, with the "Many-Faced God" as its personification. They are the world's most capable assassins, but do not consider themselves to be killers for hire. Instead, the customer is expected to make a "donation" to their temple for the privilege of selecting an individual to receive the blessing of death, the cost being deliberately so high that you really have to ''want'' someone dead. Unless it's yourself you want dead, that you can have for free with no questions asked and corpse disposal included.
* The protagonist of Eric Nylund's ''Literature/AGameOfUniverse'' works for Umbra Corp, a great example of this trope.
* Michelle West's novels have a group called the Kovaschaii, who are high-quality assassins. Among other things, they take information on the target directly from the client's mind, foiling any attempts at eavesdropping. Also, one of them does leave and become a hero, but not because they're evil or even because he wanted to: a girl who can see the future convinced him that he would be needed elsewhere to help save the world.
* ''Literature/TheExecutioner'' series by Don Pendleton. The Black Aces are elite Mafia hitmen under the control of the Five Families. Toward the end of Mack Bolan's war against the Mafia we discover they're not above manipulating the politics of the Mob for their own ends. Bolan also finds their reputation useful by pretending to be one himself.
* In ''Dreams of Steel'', a novel in Literature/TheBlackCompany series, the cult of Kina plays this role pretty explicitly. They believe that anyone they kill for the goddess Kina will go directly to paradise, so they make it their goal to kill as many as possible.
* Henry Slesar's short story "The Candidate" concerns the Society for United Action, a group of like-minded individuals who, upon deciding someone is truly "not fit to live", engages in mass wishing for the person's death, after letting them know that they've been targeted; the sheer psychosomatic effect of knowing so many people are wishing you dead has resulted in their "hits" being successful the vast majority of the time.
* The Silent Guild of ''[[Literature/AssassinFantastic History and Economics]]'' operates openly, with several of its laws not only common knowledge, but featured as obligatory reading in Introduction to Law, along with the court case "Romanez vs. the Silent Guild".
* In Creator/CJCherryh's ''{{Literature/Foreigner}}'' series, the alien atevi have a strange form of government approved Guild: someone contracts with the Guild to assassinate a target, the Guild informs the government, and the government informs the target. If the target is still killed in spite of the warning, the killing is legal. If an amateur kills someone themselves, it's illegal. If a Guild member kills someone without a Guild sanctioned contract, it's illegal ''and'' ticks off the Guild.
** In spite of being called the Assassin's Guild, and the members being called assassins, most assassins spend the majority of their time doing security work or being bodyguards, on the theory of "to catch a thief, send a thief".
* A humorous novel titled ''Going Public'' (author unknown, sorry) starred three young hitmen who decided to actually offer stock options for their assassination business, 3W Undertakings. (The "W" was because the three had adopted nicknames based on "Willie" -- Willie the WASP, Willie the [[NWordPrivileges Wop]], and Willie the Watusi.)
* ''Radio/{{The Shadow}}'' once fought an organization that offered death insurance. People would buy insurance on a person and would be payed if they did not die by a certain time. Of course, this was really a paper thin disguise for a murder for hire business, though when the organization failed to carry out a hit they did pay up.
* The Brotherhood of the Hand from ''Literature/TheDeathGateCycle'' is part Murder, Inc. and part ThievesGuild; they are the most powerful criminal organization in their world and have their hands in all sorts of dubious enterprises, but are most well-known for producing highly competent assassins, including AntiHero [[BadassNormal Hugh]].
* ''Literature/{{Neverwhere}}'' by Creator/NeilGaiman has '' "Croup and Vandemar, the Old Firm, obstacles obliterated, nuisances eradicated, bothersome limbs removed and tutelary dentistry." ''
* Subverted in Creator/JohnMoore's ''Literature/TheUnhandsomePrince''. The capital of Melinower ''does'' have an Assassin's Guild--but it's actually a fake, run by the palace guard, to catch people who might want to hire or join such an organization.
* In Sherrilyn Kenyon's ''The League'' series they have "The League", who also offer education. The entire futuristic soceity runs around a very public assassination contract system. Things like "Spill-Kills" offer bonus payment for everyone killed trying to get to the target.
* The Gray League in ''Literature/DiamondSwordWoodenSword'' is part assassin's guild, part information brokers.
* In the Yellowstone society described in ''Literature/RevelationSpace'', a number of companies provide "Shadowplay" services, which allow the bored, wealthy, immortal aristocrats living in the upper city to set an assassin on... themselves. The assassin has a limited time to kill his target (often a few months), both the assassin and the target are alerted by a special implant when they get close to each other, and there may be other constraints and requirements specified by the target (for example, limitations on weapons, or on the place of the killing). The game is designed so that most of the targets manage to escape, but around 30% get killed. Why do they do that? They are so bored that facing death is the only way they manage to feel alive, and besides, surviving a shadowplay session makes you famous and respected.
* The events in ''[[Literature/RevelationSpaceSeries Chasm City]]'' are instrumental to the creation of Shadowplay, and the end of the novel sees the foundation of the first and biggest shadowplay company, Omega Point.
* In ''Literature/{{MARZENA}}'' according to Helena, there this thing called the Coven which is a modern day evil league of super evil womyn. The Coven hide itself behind a number of companies such as Starcloud and the C-Section. They form the Feminist Mafia and controls the stock market by killing people for a profit to buy ruined companies with [[FictionalCurrency decimals on the Credit]]. There's also the United-Bank of all Nations, the UBN, money is all about profit at any cost.
* Creator/DorothyLSayers wrote a story about a firm called "Smith & Smith, Removals" that specialized in such matters. It was supposed to be part of a series, but she never wrote any more.
* Creator/AgathaChristie's ''Literature/ThePaleHorse'' had one of these.
* The ''Literature/MalazanBookOfTheFallen'' has several:
** The Guild of Assassins in Darujhistan is exactly what it calls itself. They are headed by Guild Mistress Vorcan and organized in internal clans and make it possible for noble families to settle their disputes away from the public eye.
** The Claw doubles as the SecretPolice of the Malazan Empire. They are typically trained from a young age and organized in Hands, which often include assassin mages as well. Any place facing a Malazan conquering army tends to shit its metaphorical pants at even the ''rumor'' of a Claw Hand or two having slipped in to prepare their army's arrival.
** The Talon was the precursor of the Claw, but with less emphasis on the police and more on the secret parts. It was allegedly wiped out by the Claw to secure Empress Laseen's hold on the empire, yet rumors of a few agents still existing and operating tend to have even the Claw scamper in near panic.
** The Kingdom of Lether has the peculiarly named [[WeirdTradeUnion Rat Catcher's Guild]], which purports to do just that - catch rats and other vermin. In truth, they act as the unofficial assassins guild, [[ThievesGuild the guild of thieves]], a refugee smuggling ring, ''and'' are conveniently contracted by the crown to investigate disappearances.
* ''Literature/VillainsByNecessity'': The assassins guild Sam used to be a member of.
* ''Literature/JoePickett'': In ''Stone Cold'', Joe is sent to Medicine Wheel County to investigate what retired financier Wolfgang Templeton is up to on his ranch. It turns out that Templeton is running a murder-for-hire organisation, with Joe's friend Nate as one of his operatives.

[[folder:Live-Action TV]]
* [[FunWithAcronyms Homicide International Trust]] on ''Series/MacGyver1985''.
* G'Kar from ''Series/BabylonFive'' was once targeted by someone from the Thenta Makur, a Narn assassin's guild. Their signature is leaving a red flower on the target's bed, which is a signal to get one's affairs in order. The group has such a dedication that when G'kar fakes bribing the man they sent, they cancel the contract on him and move it to the assassin out of embarrassment.
* The Mal Noche from ''Series/CSIMiami'' are supposed to be one of these. A street gang originally from South America, it's repeatedly mentioned that their business is solely in murder for hire (avoiding other lucrative businesses like selling drugs). Considering the sheer number of Mal Noche members operating in Miami, one has to think the Miami market for hired killers is booming.
* Buffy in ''Series/BuffyTheVampireSlayer'' is once targeted by the Order of Taraka, an assassin's guild hired by Spike to take her out.
* In ''Series/TheWestWing'', Toby Ziegler's father was a member of the historic Murder Incorporated.
* One episode of ''Series/MutantX'' featured Blue Bolt, an organization of BadassNormal assassins with acute hand-to-hand skills and cutting-edge technological weaponry.
* The Junshi clan from ''Series/{{Jake 20}}''.
* Tarot in ''Series/TheCape''.

[[folder:Newspaper Comics]]
* ''ComicStrip/ModestyBlaise'' has several examples, starting with "La Machina" in the very first story arc. The most notable example would be Salamander Four.

[[folder:Tabletop Games]]
* The Assamites in ''TabletopGame/VampireTheMasquerade'' and other TabletopGame/OldWorldOfDarkness role-playing games are used as hired vampiric killers. Their backstory ties them to TheHashshashin.
* In ''TabletopGame/DungeonsAndDragons'' 3.5 members of the Assassin prestige class are typically supposed to be members of an assassin's guild. in supplemental campaign material, one of the most famous of such organisations is The Garrotte, a multi-planar guild of assassins with operatives virtually everywhere. They are also the only apparent epic level assassins guild. All of this may or may not hold true in a given campaign.
* The player characters in ''TabletopGame/BladesInTheDark'' can effectively be this trope if they pick the "Assassins" crew type.

[[folder:Video Games]]
* ''Franchise/TheElderScrolls'' includes a number of organizations which may qualify, but two are most prominent: the Morag Tong and the Dark Brotherhood.
** The Morag Tong is a guild of assassins officially sanctioned by the [[OurElvesAreBetter Dunmer (Dark Elf)]] government. To put it lightly, the Dunmer [[TheClan Great Houses]] don't get along very well, and since open warring between the Great Houses would weaken the Dunmer overall, the Morag Tong was sanctioned as the solution. Whenever someone with a enough wealth to hire the Morag Tong wants someone dead, an "Honorable Writ of Execution" will be created for that person and a Tong assassin will be dispatched to kill them. They [[EvenEvilHasStandards follow a strict code of honor]] and are [[ProfessionalKillers highly professional]] in regards to their work. (Even if one of their agents could get away without getting caught following an assassination, they are still encouraged to turn themselves in and present their Honorable Writ of Execution to ensure that everything remains above board.) After aiding in [[TheKingslayer the assassination of Emperor Reman Cyrodiil III]] at the end of the 1st Era, they were outlawed everywhere in Tamriel except for Morrowind.
** The Dark Brotherhood is a fully criminal offshoot of the Morag Tong who operates throughout the rest of Tamriel. They are a much more PsychoForHire group, doubling as a [[ReligionOfEvil cult of Sithis]]. Despite this, they do still have rules, such as losing part of your paycheck for anybody else aside from the intended target dying in the mission area. They appear to very much dislike the wholesale slaughter of innocent people, but one unnoticed target or another they do seem to encourage as that is how you gain entry into the guild, just no mass murdering people for the hell of it. Also, the lower level leaders are very much sane in a professional way, and generally only care if you are doing your job right. By the time of ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', the Dark Brotherhood is now down to a single chapter in Falkreath. As such, the current leader Astrid has taken a less religious approach to things. She later proves to be quite the ControlFreak when the player is recognized as the Listener of the Night Mother fairly early on in the story, eventually resorting to [[spoiler:dealing with the head of the Emperor's personal guard to try and sell you out, only for this to backfire horribly on her]]. When first encountered, the player character can either begin a short quest chain to ''wipe them out'' or join them and put them on the path to renewed glory.
* The Assassin's Guild in the video game ''VideoGame/{{Summoner}} 2''.
* The Lotus Assassins in ''VideoGame/JadeEmpire''
* The Howling Voice Guild and Nether Gate in ''VideoGame/{{Suikoden}}''. The latter even has no fewer than ''four'' [[DefectorFromDecadence defectors]]. They're all, naturally, quite loyal to the cause once recruited.
* The main character of ''VideoGame/AssassinsCreedI'', Altaïr, is one of the Hashshashin, and the game depicts the Syrian branch; future games would depict successor incarnations of the Assassins as being more politically-motivated (namely opposing Templar schemes to consolidate control over humanity), though they're willing to invert this by actually putting contracts on Templars and hiring either Assassins or outsiders for minor targets.
* In ''VideoGame/KnightsOfTheOldRepublic'', you encounter the Genoharadan (which is claimed to be an AncientConspiracy). Sorta. This particular league of assassins is so shrouded in deception and mystery that you never really find out what it's really all about. And by the time you finish the associated quests, it may not even exist anymore. Or maybe it does. Who knows?
* Thugs-4-Less in ''VideoGame/RatchetAndClankGoingCommando''. Boasting such mottos as "If it ain't broke, we'll break it!" and "Pay for six hits and the seventh one's free." Thugs-4-Less flunkies challenge Ratchet throughout the game, and the Thugs-4-Less leader serves as one of the game's main villains, even though [[spoiler:you end up on the same side as the person who hired them in the first place. Right around the time it's revealed the thief is a good guy, and Mr. Fizzwidget doesn't really want anything more to do with you, the Thugs-4-Less leader gets a phone call to make him switch sides, and still be opposed to you.]]
* The UAA from the video game ''VideoGame/NoMoreHeroes'' follows this trope. Interestingly enough, it also sets up deathmatches between members of its own organization, allowing ambitious killers to climb their way up the UAA's assassin rankings.
** Though this is mostly because the player wants to climb the ranks.
* The International Contract Agency and the Franchise in the ''VideoGame/{{Hitman}}'' video games, though the Agency could be considered more of a VillainProtagonist in the sense that they seem to only take hits against scum-of-the-earth criminals who escaped justice, while the Franchise ''are'' the go-to people for the scum-of-the-earth criminals.
* The Molochean Hand in ''VideoGame/ArcanumOfSteamworksAndMagickObscura''. They are secretive, with an ancient and actually very compelling history, and they're quite literally ''everywhere'' you go - hot on your trail, keeping lookout in bars, and waiting for you in plot-relevant dungeons. Sadly their fearsome reputation becomes a bit implausible when you realize you've killed two dozen already, and you're not even playing a combat-oriented character.
* ''VideoGame/WatchDogs'' has the Fixers, a loose network of mercenaries and freelancers operating through Chicago's Darknet, willing to do any job for anyone, provided the price is right. Although wetwork and kidnapping are just some of the services they provide (they also incorporate skilled hackers and wheelmen in their ranks for illicit transportation and data retrieval, for instance), they are mostly used as professional assassins and hitmen.
* ''Franchise/DragonAge'':
** The Antivan Crows in ''VideoGame/DragonAgeOrigins'' fall under this category, with members being raised and trained for the sole purpose of assassinating and... well, sex. If Zevran is recruited as a companion, he shifts his allegiance from the Crows to the Warden, and if his friendship increases sufficiently he will answer questions about the organization. The Warden can also choose to take assassination side-missions from a representative of the Crows.
** ''Videogame/DragonAgeInquisition'' introduces the House of Repose, which operates from Orlais. [[AffablyEvil They're probably the most polite ruthless murderers you'll ever meet.]] They target [[spoiler:Josephine]] because of a contract against her family that was drafted a hundred years ago. Even though the original clients are long dead and their descendants no longer nobility, the House of Repose will still honor the contract for the sake of their reputation. However, since the situation is so unusual, they extend the courtesy of an explanation, so that at least she understands ''why'' they're trying to kill her. The conversation also gives her an idea of how to have the contract nullified, and though their representative warns that it will take a long time, he sees merit in the idea. If allowed to leave unharmed, he adds that "I pray we never meet again," suggesting that he personally doesn't like having to honor the contract.
* There's a dubious group on your space station in ''VideoGame/ThePerilsOfAkumos'' that deal in explosives, among other ''less'' legal activity.
* ''VideoGame/DarkSouls'' has several factions that basically exist to murder other players, particularly the Darkwraiths, Blade of the Darkmoon and the Forest Hunters.
* A group literally called "Murder, Inc." appears in ''VideoGame/DeadToRights.'' Apparently they're based in New York.
* The Crimson Lance from ''VideoGame/{{Borderlands}}'', who are the military wing of the corrupt Atlas corporation.
* The [[TheDreaded Scattered Bones]] of ''VideoGame/TalesOfZestiria''. Infamous and have a catchphrase in "[[PreMortemOneLiner may these weary bones find peaceful rest]]". They also fall under the kind with morality, researching their targets and only killing those who they feel deserve it, aka AssholeVictims. [[spoiler: Considering they used to be the famous [[HiredGuns Windriders]] their morality makes sense. They also act as the Sparrowfeathers, a group of [[IntrepidMerchant Intrepid Merchants]] who aid [[TheHero Sorey]] and others more than once.]]
* Pendles from ''VideoGame/{{Battleborn}}'' runs Executive Executions, of which he's the sole proprietor and star assassin. He advertises EE services with all the affability and charm of a professional business-minded assassin.

[[folder:Web Comics]]
* Team Vorg, from ''Webcomic/CwensQuest'', is a "business" in CQ's fantasy world who's whole business model is based around having large armies going about conquering city's and towns at the behest of their psychotic and unstable but also Reaganomic, corporate minded & business savvy leader.
* The titular group in ''Webcomic/SuicideForHire'', though it consists of just two teenagers, and their clients and their victims are the same people.
* A league of assassins assaults ''Webcomic/TheDragonDoctors'' and the magical doctors are forced to use their spells and skills to fend them off. A magical mishap turns one of the assassins into a tree, rooted to the spot in front of their clinic, and until the spell wears off (which could be years) they have to take care of her and keep her company.
