''Warhammer 40,000'', [[FanNickname known informally]] as "Warhammer 40K", "[=WH40K=]", or just plain "40K", is a miniatures-based {{tabletop|Games}} [[WarGaming war game]] by Creator/GamesWorkshop. In its beginning it drew heavily on GW's previous ''TabletopGame/{{Warhammer}} Fantasy'' game, and was essentially "''Warhammer'' [[RecycledInSpace In Space]]", but has over time [[DerivativeDifferentiation grown distinct from]] ([[MorePopularSpinoff and much more popular than]]) its counterpart. It is currently in its seventh edition.

More than anything else, 40K stands out from other tabletop wargames because of its ''[[RefugeInAudacity extreme]]'' [[SlidingScaleOfIdealismVersusCynicism darkness]]. Set roughly thirty-eight thousand years in the future, the most basic summation of the game's plot is that our galaxy has been twisted into a [[CrapsackWorld horrifying hell]] where an [[ForeverWar eternal, impossibly vast conflict]] occurs between several absurdly powerful [[KillEmAll genocidal]], [[FantasticRacism xenocidal]], and (in at least one case) [[ApocalypseHow omnicidal]] factions, with [[TropeOverdosed every single weapon, ideology, and creative piece of nastiness imaginable]] [[{{Troperiffic}} turned]] UpToEleven...and even ''it'' [[CosmicHorrorStory has a Hell]].


[[folder:More about the setting]]
In the distant past, humanity held immeasurable power and glory, but no longer. In the waning years of the 41st millennium, the game's central faction, the [[TheEmpire Imperium of Man]], is a [[{{Dystopia}} paranoid, fascist]] [[TheTheocracy theocratic state]] which spans the galaxy but is struggling mightily to maintain its grip on its territory. Its {{messia|nicArchetype}}h was [[Literature/HorusHeresy laid low by his most beloved son]] and has been locked up on life support for more than ten millennia, [[AndIMustScream physically dead yet psychically conscious]]. The incomprehensibly vast [[ChurchMilitant Ecclesiarchy]] [[CorruptChurch commits horrible atrocities in his name (but against his philosophy)]] on an almost-daily basis. The {{Space Marine}}s, capricious, fanatical, [[BioAugmentation genetically engineered]] KnightTemplar {{Super Soldier}}s and the [[AmazonBrigade Sisters of Battle]], equally fanatical, [[KillItWithFire pyromaniacal]] [[ChurchMilitant battle nuns]] serve as the Imperium's special forces, while the [[RedShirtArmy Imperial Guard]], its ''trillions''-strong regular army, takes [[WeHaveReserves disregard for human life]] to new and interesting extremes. A futuristic [[StateSec Inquisition]] ruthlessly hunts down anyone with even the ''slightest'' taint of the heretic, the mutant, or the [[FantasticRacism alien]], even going as far as [[EarthShatteringKaboom destroying entire planets]], ''[[NoKillLikeOverkill just to be sure]]''. Science and technology have [[MedievalStasis scarcely progressed for ten thousand years]], partly because they are treated with fear, [[LostTechnology ignorance]] and [[CargoCult magical superstition]], and partly because the [[{{Cyborg}} Adeptus Mechanicus]], the secretive, [[CyberneticsWillEatYourSoul deranged]] [[MachineWorship machine cult]] that maintains the Imperium's technological base, [[OlderIsBetter by and large sees innovation as blasphemy against the wisdom of the ancients]]. The Warp, the Imperium's only means of FasterThanLightTravel, carries with it a good chance of [[HyperspaceIsAScaryPlace being ripped apart by daemons in more ways than one]], and [[HumanResources the souls of psychic humans]] are [[PoweredByAForsakenChild consumed in the thousands per day]] to not only power the Astronomican, the psychic navigation aid used to negotiate Warpspace, but to fuel the Emperor's life support mechanism.

The problem is, as bad as the Imperium is, all the other major factions [[BlackAndGrayMorality are just as bad, and in many cases far worse]]. The [[SpaceElves Eldar]], an [[{{Precursors}} ancient, mysterious]] and [[TheChessmaster manipulative]] race hovering near extinction, contrive wars that see billions from other species dead so that ''[[MoralMyopia mere]] [[ItsAllAboutMe thousands]]'' of their own may survive, while their depraved cousins, the [[EvilCounterpart Dark Eldar]], [[ForTheEvulz happily perpetuate]] [[CruelAndUnusualDeath mass slaughter]] and ColdBloodedTorture to stave off the eternal punishment looming over their entire species. The [[BugWar Tyranids]], a [[HordeOfAlienLocusts mysterious, ever-hungering]] [[OutsideContextProblem extra-galactic race]] guided by a malevolent HiveMind, are rampaging across the galaxy, [[PlanetEater consuming planets']] ''[[PlanetEater biospheres]]'' to evolve and become stronger. The [[KillerRobot Necrons]], TheRemnant of an ancient alien civilization transformed into vast legions of [[ClarkesThirdLaw incredibly advanced]], [[ImmortalityImmorality undying]], [[RobotWar living metal warriors]], are awakening after millions of years of slumber to reclaim a galaxy they see as rightfully theirs and scour away the taint of organic life. The [[OurOrcsAreDifferent Orks]], a genetically-engineered warrior species who [[AlienKudzu infest]] every corner of the galaxy, [[AxCrazy cheerfully kill anything and anyone they come across]] -- including each other, if nothing better presents itself -- because it's [[AlwaysChaoticEvil literally hard-wired into their genetic code to do so]]... and because [[BloodKnight it's fun]]. The [[NaiveNewcomer Tau]], a comparatively small and young race with an insurgent cross-species empire on the galaxy's fringe, readily seek new allies through diplomacy, but are [[UnreliableNarrator reputed]] to absorb those who refuse through [[EarthShatteringKaboom orbital bombardment]], [[TheEvilsOfFreeWill concentration camps]] and possibly [[MassHypnosis mind]] [[HappinessInSlavery control]], [[WellIntentionedExtremist all to further]] [[UtopiaJustifiesTheMeans their philosophy of the "Greater Good"]]. The common foe of all is [[TheLegionsOfHell the forces of Chaos]], which lives and thrives in the Warp, [[TheCorruption corrupts all it touches]], [[GreaterScopeVillain is the root cause of much of the setting's darkness]] and is known for ''light years''-wide [[NegativeSpaceWedgie holes in reality]] through which countless [[OurDemonsAreDifferent daemons]] and [[EvilCounterpart corrupted]] [[TheDarkSide daemon-powered]] {{Super Soldier}}s periodically emerge to attempt to bring the universe to further ruin.

[[folder:How the game is played]]
The game is played on a table top or similar flat surface with added terrain, obstacles, and other objects; the standard play area is 6' x 4'. The essential tools for gameplay, aside from the models, are: the main rulebook; codexes, supplements, and dataslates which detail model stats and specific rules for the individual factions, as well as gameplay scenarios; a tape measure, as everything is measured in inches; templates for blast and flame weapons; objective cards and markers which are used in some game variants; and ''lots'' of six-sided dice (D6s)[[note]]seriously...30 is a decent number to have on hand[[/note]], including a special "scatter die" used for specific weapons and troop movements. You can pick these up separately, but GW provides a starter kit which contains the templates, a scatter die and a few D6s, enough miniatures to field two small armies, a rules-only version of the rulebook, and special rules pertaining to the armies in the kit and game scenarios. The current starter kit is ''Dark Vengeance''.

The models are divided into eight distinct categories: Lords of War[[note]]exceptionally powerful, even legendary figures[[/note]], [=HQs=][[note]]powerful leaders[[/note]], Elites[[note]]exceptionally strong units and war machines[[/note]], Troops[[note]]basic infantry[[/note]], Fast Attack[[note]]speedy units and light vehicles[[/note]], Heavy Support[[note]]heavily armed vehicles and units[[/note]], Fortifications[[note]]specific types of terrain that work in an army's favor[[/note]], and Other[[note]]models that don't neatly fit into the other categories, such as Imperial Knights[[/note]]. The 7th edition rules allow players to build their armies either as Unbound (basically bring whatever you want) or as Battle-Forged (an organized structure that includes a Primary Detachment and optional Allied Detachment, each with specific numbers of certain model categories). Battle-Forged armies use a Force Organization Chart to determine how many units/vehicles in each category can be fielded. The standard [=FOC=] has one HQ and two Troops choices at minimum, while some codexes feature their own [=FOCs=] which give differing options. Battle-Forged armies also get bonuses that Unbound armies do not. Formations can also be taken, which feature specific builds involving certain models and have their own special rules and bonuses. Some codexes' [=FOCs=] are built entirely around formations, such as the Necron Decurion Detachment or the Space Marines' Gladius Strike Force.

For each army, the models available in each category have a base point value relative to their worth in gameplay, which covers the # of models and their default weapons and armor. The rules give the player specific options to change the weapons, armor, and other bonuses depending on the category and model or unit in question, and to add models to certain units, with most changes increasing that model or unit's overall point cost. Players assemble their armies to meet an agreed-upon number of points per army prior to play, with the upper limits usually determined by the type of game being played. Normal games are typically in the 1000-2000 point range, but a beginner could easily play a 500 point game, and the Kill Team variant is designed for fast games using 200 point armies. On the other hand, Apocalypse games feature huge numbers of units per army and models that are typically overpowered for the normal game, such as faction-relevant HumongousMecha, and can have point values in the tens to hundreds of thousands or more.

Before the game begins, dice are rolled to determine the Mission for the game[[note]]killing everyone, capturing objectives, etc.[[/note]], how the battlefield will be divided between the armies[[note]]whether sides or corners of the table will be used for deployment, how many terrain pieces are to be used, etc.[[/note]], various challenges and model abilities[[note]]Warlord Traits and Psychic Powers, for example[[/note]] that influence gameplay, and who gets to deploy their army first. There are twelve Missions in the core rulebook, six "Eternal War" Missions that are carryovers from previous editions and six "Maelstrom of War" missions introduced in 7th edition. These have a general theme like the Eternal War missions but also use Tactical Objectives which give specific tasks that the player can attempt to accomplish during each turn. The first player to deploy gets to start the first turn, with the second player having a chance to roll to go first, or "steal the initiative".

Games have a maximum of 7 turns; whether or not turns 6 or 7 happen is determined by die rolls starting at the end of turn 5. Each game turn has two player turns, each having four phases: Movement, Psychic, Shooting, and Assault. In the movement phase, specific rules govern how far different models/units can move and how movement affects what they can do in the subsequent phases. The moving player can also elect to "run" a model or unit in the shooting phase, passing up the chance to shoot to move it further. Anything being held in reserve can also be potentially brought in during the movement phase starting on turn 2. In the psychic phase, the attacking player rolls 1D6 to set the Warp Charge pool; both players then have the Warp Charge pool plus the sum of their models' psychic "mastery levels" worth of Warp Charges in total. The attacking player then spends one Warp Charge per die rolled to cast powers, with failed rolls, "Perils of the Warp", and/or the defending player using his Warp Charges to try to negate successful rolls factored in. During the shooting phase, dice are rolled for each weapon being fired to determine whether the attack hits and then whether it actually causes wounds or damage. In the assault phase, die rolls determine whether or not a unit can move into melee combat with a target. Combat then follows a structured order of attacks, with die rolls for hits and wounds/damage in the same manner as in the shooting phase. In the psychic, shooting, and assault phases, if possible, the defending player can roll for various types of saves to attempt to negate damage or wounds, and can potentially counterattack in the assault phase. Characteristic tests, special abilities and features unique to each faction, weapon-specific rules, terrain effects, and other such actions also influence the progress of each phase. A game turn is complete at the end of the second player's assault phase; the process then starts over again with the next turn.

Players acquire victory points as they eliminate sections of the opponent's army from the game, when Mission-specific objectives are achieved, and when Tactical Objectives are achieved during a turn. All Missions are won by majority of victory points; draws are possible. "Tabling" the opponent[[note]]completely eliminating his models that are present on the tabletop, regardless of what he may have in reserve[[/note]] is an automatic win regardless of the score.

[[folder:The Hobby]]
One of the major aspects of 40K, aside from the gameplay, is the actual work that goes into the miniatures. Just like any other model kit, 40K minis come unassembled and unpainted, and it's up to the player to put in the legwork to literally build their army. The model kits come in a variety of ways, such as single blister packs or boxes that contain one model, a boxed unit, or as larger box sets that contain many models and allow the player to obtain a large chunk of his army at once. Models are generally glued together piecemeal using plastic or super glue (for plastic and resin/metal, respectively), but the starter kits' minis are designed to be snapped together with limited gluing necessary, speeding up the building process. The kits feature a large number of ways that models can be customized, and kit-bashing models is a good way to spruce them up and to make use of [[BitzBox spare bitz lying around]].

Possibly even more important than assembling the models is painting them. It's generally seen as bad form to field an unpainted army, especially for factions like the Space Marines that have many different chapters and where a lot of the models look exactly alike, making painting them the accepted way to determine which particular chapter you're playing. Painting models to a "tabletop" quality level[[note]]painted well enough so that the models don't look sloppy at an at-the-table perspective and particular factions are easily distinguished[[/note]] is considered the norm, and tournaments will often require a certain level of completion of painting, but players can put as much or as little effort into it as they wish, although they're often encouraged to go beyond tabletop quality. GW produces painting guides and free online tutorials, but other tutorials are readily available through Website/YouTube and dedicated painting sites. GW uses Citadel products for its models, paints, glues, and tools, and all of its painting methods and tutorials are built around using them, but equivalents from other companies are readily available, and tutorials will vary wildly between paints, glues, and other materials. There are ''many'' different ways to go about painting models, and settling on one is up to the player's tastes and budget and the availability of supplies...the general rule is "find what works for you and run with it."

Thus, 40K is just as much a hobby as it is a game. It's perfectly fine to ignore the game aspect altogether and devote yourself to building and painting the miniatures, whether it's for simple recreation, for display and competition, or even as a business. There are many artists and sites who do commission work for others, doing anything from simply painting minis to the entire process of assembly and painting, and from quality levels ranging from tabletop-quality to work similar to what you see on show cars. GW recognizes the best of the best through an annual competition called the Golden Daemon Awards, where painters show off models that have been painted and based to standards ''far'' beyond tabletop-ready, to the point that they have become works of art.

Apart from the game itself and its rulebooks, faction-specific, setting-specific, and campaign sourcebooks, 40K has spawned a range of [[ExpandedUniverse spinoff games and publications]]. Dozens of novels and short story anthologies are published by the Black Library, a subsidiary of Games Workshop, who also published the now out-of-print comic book ''Warhammer Monthly'' and short story magazine ''Inferno''. Boom! Studios now publish comics set in the 40K universe, in the form of various mini-series, rather than an ongoing title. There is even a full-length fan film, ''Film/{{Damnatus}}'', which was approved, made, banned over conflicts between British and German IP laws, then leaked online. An official CGI movie, ''WesternAnimation/{{Ultramarines}}'', was released in 2010, following up on a number of live-action shorts shown at various Games Day events in the 90s.

In the meantime, you can track down an old Games Workshop VHS release film called ''Inquisitor'', or even watch ''Film/EventHorizon'' (which has long been [[{{Fanon}} accepted as an unofficial prequel]], since the creators seem to have accidentally matched the franchise's premise and style with remarkable exactitude, though not the time period). There is also another fan film being produced called ''The Lord Inquisitor'', which will be fully CGI. Unlike the incident with ''Damnatus'', Games Workshop is perfectly fine with the existence of the movie and will not be taking legal action against its production.

As you may have guessed from the incredible size and attention to detail on this page, [[FanNickname 40K]] has a huge, diverse, and fanatical following, despite the niche status of the hobby. The franchise has a lot of appeal even to people who don't play the wargame itself (or used to play it and only keep in touch with the lore), and who only follow the spinoffs (many of which are perfectly good in their own right). You don't have to [[CrackIsCheaper spend all your money]] to experience the inimitable insanity that is ''Warhammer 40,000''.

[[folder:Spin-offs and games that do not have their own pages]]

* ''Aeronautica Imperialis'': Air-combat spin-off tabletop game.
* ''Epic 40000'': Uses very small scale miniatures, allowing the players to field huge armies and extremely powerful units such as the largest [[HumongousMecha Titans and Gargants]] and even [[EldritchAbomination Daemon Primarchs]].
* ''Final Liberation'': ''Epic''-based turn-based strategy video game, with FMV cinematics that look like a fan film.
* ''Aspect Warrior'': Isometric shooter video game.
* The various counter-based BoardGames, including ''Battle for Armageddon'' (and the add-on ''Chaos Attack''), ''Horus Heresy'', ''Doom of the Eldar'', ''Warmaster'', ''Arena of Blood'', and ''Relic''.
* The card games.
* ''Dark Millennium'': Upcoming {{RPG}}, initially an MMO until Creator/{{THQ}}'s financial difficulties forced cut backs. An unconfirmed rumor claims it has been passed to EA for further development.
* ''Blood For The Blood God'', ''Hive Infestation'' and ''Inquisitor'': Obscure live-action shorts.
* ''Rites of War'': Turn-based computer strategy game starring the Eldar, using the ''VideoGame/PanzerGeneral'' engine.
* ''Armageddon'': A turn-based computer strategy game, using the Panzer Corps engine, from Slitherine Games, about the ''Second'' War for Armageddon involving various Space Marine chapters, Imperial Guard & Orks.
* ''Space Crusade'': A board game somewhat similar to ''Space Hulk'' in which up to three players control a squad of Space Marines each, attempting to fight their way through a space hulk filled with a mix of Orks, Genestealers and Chaos troops controlled by another player. Although apparently set in the Warhammer 40K universe, including use of Space Marine chapter names, it was developed jointly with Milton Bradley and, as with other similar joint games such as ''TabletopGame/HeroQuest'', never makes any mention of the actual setting.
* ''Warhammer 40000: Glory in Death'': An obscure title for the ill-fated Nokia N-Gage handheld/cellphone combo released in 2006. Either nobody bought it or it had a hilariously limited release because it's got a stub on TheOtherWiki and is mentioned on the N-Gage page, and not a lot else.
* ''Warhammer 40,000: The Freeblade Chronicles'': A RailShooter /ActionRPG hybrid for mobile phones, dealing with a dispossessed Imperial Knight rescued by the Dark Angels.
* ''Space Wolf'': A mobile phone [[FightLikeACardPlayer card-battle]] StrategyRPG.
