Forget the promise of progress and understanding, for in the grim darkness of the far future there is only war.
There is no peace amongst the stars, only an eternity of carnage and slaughter, and the laughter of thirsting gods.
Warhammer 40,000, known informally as "Warhammer 40K," "WH40K," or just plain "40K," is a miniatures-based tabletop war game released by Games Workshop in 1987. In its beginning it drew heavily on GW's previous Warhammer Fantasy game, and was essentially "Warhammer In Space," but over time grew distinct from (and much more popular than) its counterpart. Its ninth edition was released in 2020.
More than anything else, 40K stands out from other tabletop wargames because of its extreme 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 unfathomable horror where an eternal, impossibly vast conflict occurs between several absurdly powerful genocidal, xenocidal, and (in at least one case) omnicidal factions, with every single weapon, ideology, and creative piece of nastiness imaginable turned Up to Eleven... and even it has a Hell.
As bad as the Imperium is, however, all the other major factions are just as bad, if not far worse. The Eldar, an ancient, mysterious and manipulative race nearly destroyed by the fallout from their ancestors' decadence, are best known for contriving wars that see billions from other species dead to spare mere thousands of their own that fate, while their depraved cousins, the Dark Eldar, happily perpetuate mass slaughter and Cold-Blooded Torture, both trying to stave off the hellish afterlife looming over their entire race. The Tyranids, an extra-galactic race of ever-hungering virus-like monstrosities guided by an animalistic but highly intelligent Hive Mind, are rampaging across the galaxy, consuming everything they come across (including planets' biospheres) to evolve and become stronger. The Necrons, The Remnant of an ancient alien civilization transformed into vast legions of undying warriors made of living metal and possessing incredibly advanced technology, 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 Orks, a genetically-engineered warrior species infesting every corner of the galaxy, cheerfully battle anyone that might give them a good fight — including each other, if nothing better presents itself — because it's literally hard-wired into their genetic code to do so... and because it's fun. The T'au, 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 reputed to absorb those who refuse through orbital bombardment, concentration camps and possibly mind control, all to further their philosophy of the "Greater Good".
Worst of all are the Chaos Gods, four ruthless, destructive deities who can only exist in the Warp, but are the root cause for most of the setting's darkness. Sustained by the beliefs and emotions of living beings, they exude a deadly energy force that taints anything it comes into contact with, including people's bodies, minds and the ground under their feet. Their fighting forces, which include Chaos Cultists (humans, mutants and aliens perverted into Chaos worship), Chaos Daemons (fragments of the Chaos Gods given life, who are well-known for their capacity to strike deals with, manipulate and possess people) and Chaos Space Marines (heretical Space Marines who have turned against the Imperium for a variety of reasons, including greed, lust for power, disillusionment, and revenge), sow ruin and bloodshed wherever they go. Most infamously, the forces of Chaos frequently rip open portals and large rifts into the material plane from which they emerge to wage war, the most recent of which stretches across the entire galaxy and has split the Imperium in two.
The models are divided into nine distinct categories: Lords of War,note HQs,note Elites,note Troops,note Dedicated Transports,note Fast Attack,note Heavy Support,note Fortifications,note and Flyers.note The 8th edition rules allow players to build their armies either as Open Play (basically bring whatever you want), Narrative (recreating historical battles from the fluff or themed campaigns), or Match Play (building armies along an organized structure with specific numbers of certain model categories, determined by a Force Organization Chart). There are six default FOCs, each with a set number of HQ and Troops slots as base requirements and varying numbers of slots for other model types. Match Play armies also get bonuses that the other play styles do not, and give the player certain amounts of Command Points which can be used during the game in various ways.
For each army, the models available in each category have both a Power rating and a base point value relative to their worth in gameplay, which covers the # of models and their default weapons and armor. The Power rating is generally geared toward Open and Narrative games while the points values are geared toward Match Play. 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. Power ratings will generally only increase if models are added to units while points values will often increase with both additional models and weapon changes. Players assemble their armies to meet an agreed-upon total Power rating or number of points per army prior to play, with the upper limits usually determined by the type of game being played.
Before the game begins, dice are rolled to determine the Mission for the game,note how the battlefield will be divided between the armies,note various challenges and model abilitiesnote that influence gameplay, and who gets to begin deploying their army first. There are twelve Missions in the core rulebook, six "Eternal War" Missions that are carryovers from older 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 finish deploying his army gets to choose whether or not to start the first turn; if he does, the second player has a chance to roll to go first, or "seize the initiative."
Games have a maximum of 7 battle rounds; whether or not rounds 6 or 7 happen is determined by die rolls starting at the end of round 5. Each round has two player turns, each having six phases: Movement, Psychic, Shooting, Charging, Assault, and Morale. In the movement phase, the models' stats govern how far they can move and how movement affects what they can do in the subsequent phases. The moving player can also elect to Advance a model or unit, 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, so long as all such models are deployed by the start of round 4. In the psychic phase, the attacking player attempts to use psychic powers by rolling 2D6 to meet or beat each power's casting cost, with failed rolls, "Perils of the Warp," and/or the defending player attempting to negate successful rolls factored in. During the shooting phase, dice are rolled for each weapon being fired to determine whether it hits and then whether it actually causes wounds. In the charging phase, die rolls determine whether or not a unit can move into range of a target unit to enter melee combat. In the Assault phase, units pile into each other and engage in melee combat, with the player that charged in the previous phase getting first strike and then alternating between players. As in the shooting phase, die rolls determine hits and wounds. In the morale phase, the players determine the number of models lost from each unit and, if needed, roll a D6; if the combined result is greater than the unit's max Leadership value, the unit loses a number of additional models equal to the difference. In the psychic, shooting, and assault phases, if possible, the defending player can roll for armor or invulnerable saves to attempt to negate 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 battle round is complete at the end of the second player's Morale phase; the process then starts over again with the next round.
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 opponentnote is an automatic win regardless of the score.
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 levelnote 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 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 Demon 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 spinoff games and publications. Hundreds 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. Marvel Comics now publishes 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, Damnatus, which was approved, made, banned over conflicts between British and German IP laws, then leaked online. An official CGI movie, 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 Event Horizon (which has long been 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, 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 spend all your money to experience the inimitable insanity that is Warhammer 40,000.
- 40K Lexicanum and 40K Wiki — Two large and comprehensive wikis. Formatting and citation methods are very different between them, and the Lexicanum tends to be more concise.
- 1d4chan — Another wiki, a spinoff of 4chan's /tg/ board; it covers many games, but Warhammer 40,000 is highly represented. It features a lot of info about the game's fanon and fan works as well as the game itself. It's very informal in tone, steeped in 4chan's lingo and culture, and generally NSFW, so be prepared.
- Websites and YouTube channels featuring battle reports, painting lessons, discussions of rules, codex reviews, and other game-related items:
