->''"Sometimes, late at night when I can't sleep, I remember my father. We lived in a [[UsedFuture rust park]] near Omni-1, in one of those ... port-a-junk mobile homes. There were no perimeter fences, so when I was just four, my father showed me how to fire a gun. 'To protect me from the lizards,' he said.''

->''I turned six when he took me to see where the first colonists had landed. I remember I wasn't very impressed; I'd expected something monumental, but there was only concrete and steel and a holographic plaque inscribed with Omni-Tek corporate propaganda. The sights seen by the pioneers were long gone, replaced by an urban wasteland.''

->''That was the first time my father told me about the war. At first, Rubi-Ka wasn't much more than a mining outpost. The workforce had been brought in from the asteroid belts and drilling operations on Mars--and Omni-Tek figured that the miners would be pliant and expendable. Their mistake. My father said that the rebellion changed everything, and not just for the better. It's never that simple, but still, there's no home without freedom. And we ''needed'' freedom, because we wanted to make Rubi-ka ''our'' home.''

->''My father taught me how to use a gun. Sometimes, late at night ... I wonder if I'll ever be able to put it down."''
-->--'''Anonymous Clan Member''', Original OpeningNarration

Over twenty-eight thousand years into the future, survey ships from [[MegaCorp Omni-Tek]] discover Rubi-Ka, [[SingleBiomePlanet a desert wasteland of a planet]] that possesses a substance found nowhere else in the known universe--Notum, which gives {{Nanomachines}} enough power to function outside the human body, revolutionizing nano-technology. Omni-Tek spends centuries colonizing and developing Rubi-Ka for settlement, along the way [[CorporateWarfare fighting corporate rivals]] for control of the planet as well as its own planetside workforce, who rebel against the company's gross mistreatment of its laborers and form the Clans.

It turns out, however, that Rubi-Ka and mankind have a much older shared history than anyone would have thought--and humanity is not the only species with a vested interest in the planet. Scientists discovered the Shadowlands, a parallel world linked to Rubi-Ka that holds secrets on the origins of mankind and life in the universe. Just as explorers started plumbing those secrets, however, an alien species known as the Kyr'Ozch invaded Rubi-Ka. Now the situation on the planet has become truly chaotic as Omni-Tek and the Clans continue to wage war on one another even as they fend off the aliens.

Developed by the Norwegian company [=FunCom=] and launched on June 27, 2001, ''Anarchy Online'' is a rare breed in the MassivelyMultiplayerOnlineRolePlayingGame industry. ''Anarchy Online'' is noteworthy for setting a number of firsts (or at least being part of the first wave); it's one of the first SciFi [=MMORPGs=], one of the first to implement instanced content in the form of on-demand randomized missions, one of the first to implement a "free to play" business model, and also one of the first with a completely open-ended PointBuildSystem. It's also one of the first [=MMORPGs=] that gave [[AnAdventurerIsYou Petmaster]] classes the ability to control more than one pet.

Despite a ''very'' rocky launch that involved serious stability, registration, and billing issues (and which took half a year to fix), ''Anarchy Online'' has survived to this day. In total, it's had three {{Expansion Pack}}s (''Shadowlands'', ''Alien Invasion'', and ''Lost Eden'') and two "booster" packs (''Notum Wars'' and ''Legacy of the Xan''). Development on the game hasn't stopped, either; in 2008, [=FunCom=] started work on a comprehensive graphics upgrade, intent on bringing ''AO'' closer to modern standards of quality. 2013 saw beta testing of the graphics overhaul, which also includes completely reworked low-level content to better prepare the modern MMO player for the wilds of Rubi-Ka.

----
!!''Anarchy Online'' provides examples of:
* AKA47: The Desert Reet, the game's answer to the Desert Eagle.
* AnAdventurerIsYou: By the given archetypes on that page, professions are broken down as--
** The Tank: Enforcer, Soldier in a pinch, Martial Artist for the ninja style.
** The Healer: Doctor, Adventurer, Meta-Physicist and Martial Artist in a pinch.
** The Nuker: Nano-Technicians were ''made'' to nuke, but Bureaucrats and Meta-Physicists can also handle this role.
** The [=DPSer=]: Shades out-damage whole teams, with Soldiers and Martial Artists bringing up the front. In theory, this is also the Agent's role.
** The Mezzer: The Bureaucrat's specialty, but Nano-Technicans and Traders aren't slouches at this either. Adventurers and Meta-Physicists can also fill this role in a pinch.
** The Jack: The Adventurer and Meta-Physicist are the primary Jacks of the game. Agents go here too--''if'' you can find 'em.
* AncientKeeper: Ergo, Ergo, and yet again Ergo.
* AppliedPhlebotinum: Notum, and in the Shadowlands Expansion, Novictum.
* BackStab: The "Sneak Attack" special available to two professions, as well as a similar attack for the ranged professions known as Aimed Shot.
* BarrierWarrior: The Soldier profession.
* BilingualBonus: The "songs" sung by the Yutto [=NPCs=] are actually taken from a Norwegian song that was entered in the [[EurovisionSongContest Eurovision contest]] (and lost spectacularly).
* BodyBackupDrive: The basis for Insurance Technology that makes death a slap on the wrist. Rubi-Kans within a certain age range can get their bodies scanned at an insurance terminal, saving their current physical state. At the moment of death, a new copy of their body is created at the last insurance terminal they used, and their life force is transferred into it.
* CameBackWrong: The Condemned Subway's deeper tunnels are full of monstrous, aggressive humanoids with names like "[[DamagedSoul Fragmented Soul]]," "[[SoullessShell Empty Shell]]," "Molested Molecules," "Redundant Scan," "Premature Pattern," "Incomplete Rebuild," "Neural Burnout," "Neural Breakdown," and "[[TwoBeingsOneBody Melded Patterns]]." They're the product of errors and glitches with insurance terminals. They have suitably [[BodyHorror horrific appearances]]--Melded Patterns, for instance, has double the facial features.
* CoolShades: Very common, now that the game has a "social" layer for appearance that overrides armor. In the early years, it was the Fixer profession that was known for wearing these at all times.
** A class-specific set of armor could only be worn when wearing certain items--eyeware like this being one of them.
* DeathIsCheap: Thanks to Notum, Rubi-ka is one of the only places in the known universe where this is possible through "Insurance Technology," which transfers a dying person's life force into a [[BodyBackupDrive fresh copy of their body]]. It can't halt aging, though--the new body has to be created from recently scanned data--and it doesn't allow for immortality as it stops working once a person gets too old. Regardless, [[http://www.anarchy-online.com/wsp/anarchy/frontend.cgi?func=publish.show&template=content&func_id=1762&table=CONTENT getting killed on purpose]] actually became ''a sport'' among the young, rich, and reckless. After insurance technology was deregulated, Omni-Tek even tried to attract new colonists with the advertising slogan "Rubi-Ka: Where Death Isn't Fatal!"
* DeathIsASlapOnTheWrist: The early game averted this by having various penalties for dying--up to and including losing all items, credits, and experience acquired since the last visit to an insurance terminal. Typically these would remain on one's corpse, free for looting. Later patches gradually removed these penalties save for "resurrection sickness," in which skills and abilities are lowered for a short period. Any experience lost now goes into a pool that is regained with additional experience earned.
* DeflectorShields: The bread and butter of the whole Soldier profession.
* EccentricMillionaire: Efen Christe, better known on Rubi-Ka as Lord Galahad of the Knights of Avalon. Before he decided to buy up land from the Clans and build his own version of Camelot, he was originally an interstellar trading mogul that traded with human colonies throughout the galaxy. He gave up all of that when he became Lord Galahad.
* EliteTweak: The game uses an implant system to buff skills on top of whatever buffs are available, and almost any skill can be buffed in this way (with limitations). This results in some of the most grossly overpowered and impressive "twinks" to walk the deserts of Rubi-Ka, capable of wiping the floor with platoons of lesser characters.
** To curb all the tweaking, [=FunCom=] implemented "soft" level limits--utilizing equipment or pets of significantly higher level causes them to operate at reduced effectiveness, depending on how far they are above you, and simply not function at all if they're too high.
* EverythingIsOnline: The Nano Controller Units every character has work this way. [=NCUs=] are critically important, since characters control their nanomachines through nano-programs active in the NCU's memory. Characters can also upload and execute nano-programs in others' [=NCUs=]--and hack the [=NCUs=] of their enemies to make their nanomachines execute [[DamageOverTime harmful]] or [[StandardStatusEffects debilitating]] nano-programs.
* [[FiveRaces Four Breeds]]: Unlike most other settings where the player can choose a race for his character, the choices available in ''Anarchy Online'' are all different species (or breed) of homnid. The type of breed determines how costly it is to spend points building up a specific trait or skill. Story-wise, all of the breeds were created by Omni-Tek (with the exception of Solitus).
** Solitus: Descendants of modern humans which naturally evolved after apocalyptic events on Earth thousands of years ago. They're the only breed that ''wasn't'' created via genetic engineering (and therefore [[HumansAreAverage the yardstick by which the other breeds are measured]]).
** Atrox: The first of the breeds developed by Omni-Tek, designed for heavy lifting jobs in the Notum mines. The Atrox genome is optimized to maximize strength and stamina, [[DumbMuscle at a cost of capacity for intelligence and nano-programming]]. Of the breeds, they're only ones that are genderless, completely lacking sexual organs.
** Opifex: Initially developed by Omni-Tek for tunnel-running in Rubi-Ka's mines, then adapted for stealth and assassination. Accordingly they're well suited to playing TheSneakyGuy or FragileSpeedster roles.
** Nano: The youngest of the breeds, developed for high intelligence and skill at nano-programming at a cost of physical durability. Trace amounts of Notum were added to their DNA structure, which not only prevents them from living off-world, but also renders most of them sterile.
** In addition to the four playable breeds, there are a number of failed breed specimens in Rubi-Ka's wilds that escaped Omni-Tek's labs.
* GunsAkimbo: The Adventurer profession has the option to wield either two swords or two pistols as their WeaponOfChoice, and yes, this means the Adventurer also is lucky enough to have DualWielding, but not one gun with one sword ... yet!
* ImprobablePowerDiscrepancy: There are some versions of fleas on Rubi-Ka which could easily kill a lot of dungeon bosses. Granted, Rubi-Ka's fleas tend to be no smaller than a basketball.
* KingArthur: Arthurian legend makes appearances, both on Rubi-Ka and in the Shadowlands.
** Some time after the second civil war on Rubi-Ka, Efen Christe bought substantial land from the Clans and used it to [[StartMyOwn start his own clan]]--the Knights of Avalon, who dedicate themselves to reviving the old Earth traditions of chivalry. Everything about the Knights draws right from Arthurian Legend--they named their land Avalon, they built a modernized medieval village and castle (which they, of course, call Camelot), and all the prominent members have named themselves after Arthurian figures (with the Efen claiming the name "Lord Galahad"). As might be expected, all of the Knights use medieval-inspired armor and weapons. They even have their own genetically-engineered dragon!
** Much of the Shadowlands also have motifs that draw right from Arthurian legend, despite the fact that the events hinted at in various flavor texts happened at the very least several thousand years before KingArthur was around. Commonly drawn motifs are: Merlin, Arthur as the FisherKing, often hinted at as being the Beast, the final boss of the whole dimensional area you're in, and Lord Galahad and Lord Mordeth (Mordred) as the final leaders of the Redeemed and Unredeemed respectively before reaching the blasted, hellish area known as Pandemonium.
* LethalLavaLand: Inferno, an aptly-named area within the Shadowlands.
* LevelGrinding: An estimated 320 levels to work through (though not in straight progression) makes for much grinding. Broken down as follows--
** Regular experience which accounts for levels 1-200.
** Shadowlevels which can only be earned in the Shadowlands and cover 201-220.
** Alien levels which is earned by killing aliens, which is counted as a separate number from the other levels, so you have 220/30.
** Lost Eden Research levels, which can be earned at any time by diverting some of your experience into "research." It has 7 lines with 10 levels apiece, resulting in a three-level cap (220/30/70).
* LongRunners: Over a decade old and still going!
* MagicByAnyOtherName: A number of nanotechnological concepts in ''AO'' are functionally identical to magic in a typical fantasy setting. Nano-programs can be thought of as spells, and nano-programming as spellcasting. "Executing nano-programs in someone's NCU" might as well be "casting spells on them."
* MagicFromTechnology: Notum-powered nanotechnology can allow for powers and abilities that look very much like magic to the unaware. Some groups (like the Knights of Avalon and the cultists in the Temple of the Three Winds) explicitly prefer magical aesthetics.
* MascotMook: Leets have taken on this role over the years.
* {{Megacorp}}: Omni-Tek. Putting aside the backstory setting them up as corrupt and abusive, whether or not they're truly evil is up for debate. The ''Shadowlands'' expansion saw Omni-Tek allied with the dark Unredeemed, and the Clans siding with the light Redeemed, which appeared to present a DarkIsEvil and LightIsGood dichotomy--but even now this is debated.
* MoneySink: This game has been an interesting experiment on how to get people to spend billions of credits while not giving them so much of an edge over normal players that game balance would be trashed. Examples of this includes--
** The Clinique Plastique, where you pay 25 million credits to change your character's features, height and build.
** IP reset points, costing 250 million, with the release of ''Lost Eden''.
** A special apartment in orbit above Rubi-Ka, available for only 989 million credits (out of the 1 billion maximum per character).
* {{Nanomachines}}: Pretty much everything under the twin suns of Rubi-Ka has something to do with nanomachines--either built by, maintained by, destroyed by or recycled by nanomachines. Nano Programs are used to tell the nano bots in the air around you what to do and how to do it. Much of the flavor text on many items also goes into how nanomachines are applied to the item in question.
* ObviousBeta: The original release was a notorious train wreck, with terrible connection issues and {{Game Breaking Bug}}s far beyond the normal birthing pains of an MMO, resulting in serious panning by reviewers. However, the devs worked overtime to iron things out, eventually winning AO multiple "most improved game" awards.
* PlayerGeneratedEconomy: As might be expected of an MMO, ''AO'' has one. Unfortunately, the game economy has been subject to serious player-driven inflation despite multiple {{Money Sink}}s. Among the player market, it's common to find items selling for far more money than a single character can hold. Players get around that cap with "mules" (characters that exist just to hang on to more money).
* ProductPlacement: One of the in-game bars plays music recently released in RealLife. It's [[JustifiedTrope Justified]] by the fact that although the game takes place tens of thousands of years in the future, Rubi-Ka is on the far side of the galaxy from Earth.
** More famously (and more fourth-wall breaking), ''AO'' implemented ads for RealLife products as part of its switch to a free-to-play business model. Players with subscriptions, however, could choose to turn them off.
* PVPBalanced: Initially ''AO'' was designed this way, but over the course of two expansions the dynamic became considerably unbalanced. The ''Lost Eden'' expansion helped to correct this problem.
* RainbowPimpGear: As one of the early generations of [=MMORPGs=], ''AO'' exhibited this for years until March 2008, when the Social Clothing Mode was released with patch 17.8 (see VirtualPaperDoll below).
* RandomDrops
* RandomlyGeneratedLevels: Instanced missions from mission terminals have procedurally generated descriptions, goals, enemies, locations, and layouts.
* RareRandomDrop: Some of the lowest drop rates in game history.
* RidiculouslyCuteCritter: Leets were designed for this, despite also being a TakeThat to certain types of players as a form of SmallAnnoyingCreature. Their sound files in ''AO'''s directories are even labeled with the prefix "cute." Over the years [=FunCom=] has put less emphasis on the mocking aspect: dozens of unique Leets have turned up, as well as Leet [=NPCs=] which can carry on conversations, albeit in cutesy [[WebOriginal/LOLCats kitty pidgin]].
* ShapeShifting: Mostly voluntary (with very rare exceptions). The Adventurer profession is considered king of this particular domain, thanks to a wide selection of nano-programs for the purpose.
* ShootingSuperman: Especially after ''Lost Eden'' and the patches that came afterward, a sufficiently leveled character has enough power to casually ignore most monsters that aggro them in the wild. The Meta-Physicist profession and Soldier profession both stand out with their unique flavors of DeflectorShields.
* SlippySlideyIceWorld: The Penumbra area of the Shadowlands replaces the "Slippy Slidey" part with "will freeze to death without the proper gear," but otherwise qualifies.
* TakeThat: [=FunCom=] has engaged in this several times over ''AO's'' history. Some highlights--
** The rodent-like Leets and parrot-like Reets were designed as this from the start. Both of them are parodies of players who speak exclusively in internet shorthand and who have no respect for the "RP" in "MMORPG" (for example, attacking a Reet might get it to scream "MY FRIENDS WILL KILL U" in response). The original "Backyard" tutorial zones have billboards informing players that Leets are vermin and are to be killed on sight.
** After months of complaints from the Meta-Physicist players that their summons were underpowered, the developers finally gave them an adequate endgame summon called "[[SignificantAnagram The Rihwen]]." Rearrange the letters and you get "The Whiner."
** One of ''AO's'' advertisements takes a shot across the bows of both ''VideoGame/{{Everquest}}'' and ''VideoGame/WorldOfWarcraft'' by claiming it's "lightyears beyond elves."
* TarotMotifs: The various glyphs acquired in the Shadowlands to upgrade professional Tier armor falls right into this motif.
* TruceZone: Most Neutral-aligned cities and zones can be freely visited by both Clan and Omni-Tek members.
* VariableMix: The game's music consists of hundreds of possible short clips, designed to flow into one another depending on the character's affiliation, location, and (if in battle) how well the fight is going.
* VideoGameTutorial: ''AO'' has had several flavors of this--
** Prior to the release of ''Alien Invasion'', when a player created a new character, they first spawned in their chosen faction's "Backyard," in which a Guide NPC would provide tutorials on basic game functions in a very direct "HeKnowsAboutTimedHits" fashion. Each side had a [[http://www.ao-universe.com/index.php?id=14&pid=441 thematically different Backyard]] and attached "dungeon" for combat training--Omni-Tek's was a "holo world," the Clans had an open-air entertainment park, and the Neutrals had a junkyard full of toxic waste. Though depreciated, the Backyards can still be accessed through the apartment complexes in any city.
** By ''Alien Invasion'', new characters (aside from ''Shadowlands''-based Keepers and Shades) instead received a JustifiedTutorial: they would be en route to the island-based ICC Shuttleport as a new arrival to Rubi-Ka, only to have their shuttle shot down by Kyr'Ozch forces who are attacking the facility. From there, they would [[http://www.ao-universe.com/index.php?id=14&site=AO-Universe%2FKnowledge%2F&pid=425&lang=en#4 embark on a number of quests]] to help the emergency crews and the joint Omni-Tek/Clan forces fend off the invaders before departing.
** With the release of the graphics engine upgrade, [=FunCom=] implemented a New Player Experience , including a new tutorial that replaced the ICC Shuttleport opening from ''Alien Invasion''.
* VirtualPaperDoll: The Social Clothing Mode in the equipment tab allows players to dictate the exact apparel of their characters. Any equipment placed in the Social slots will appear in place of the armor the character is wearing--letting players wear casual clothing or a specific set of armor they liked without worrying about missing out on stat boosts. Unfortunately, this is often demonstrated with [[{{Squick}} Atroxes in pink short shorts and NOTHING else]].
