Warhammer 40,000 (informally known as Warhammer 40K, WH40K or simply 40K) is a tabletop miniatures wargame produced by Games Workshop, set in a dystopian science-fantasy universe. Warhammer 40,000 was created by Rick Priestley in 1987 as the futuristic companion to Warhammer Fantasy Battle, sharing many game mechanics.
The Greatest Warhammer 40k Race,
Space Marines
The Space Marines or Adeptus Astartes are foremost amongst the defenders of humanity, the greatest of the Emperor of Mankind's warriors. They are barely human at all, but superhuman; having been made superior in all respects to a normal man by a harsh regime of genetic modification, psycho-conditioning and rigorous training. Space Marines are untouched by plague or any natural disease and can suffer wounds that would kill a lesser being several times over, and live to fight again. Clad in ancient Power Armour and wielding the most potent weapons known to Man, the Space Marines are terrifying foes and their devotion to the Emperor and the Imperium of Man is unyielding. They are the God-Emperor's Angels of Death, and they know no fear.
Eldar
The Eldar are a race of fey-like humanoids similar in appearance and culture to the sylvan elves of ancient Terran mythology and literature, and they are the most ancient and technologically advanced of all the intelligent races of the Milky Way Galaxy, with the exception of the Old Ones, and their ancient enemies the Necrons. Their armies usually have the advantages of great mobility, potent psychic abilities and technology that is more advanced than that deployed by the human Imperium. In the sense that Warhammer 40,000 races are generally derived from the earlier Warhammer Fantasy universe, the Eldar are derived from the High Elves of the Warhammer World, except for the Eldar faction known as the Exodites who are the equivalent of the Wood Elves.
Chaos Space Marines
A Chaos Space Marine, also sometimes called a Traitor Marine or a Renegade Marine, is a former Loyalist Space Marine of the Imperium of Man who has chosen to betray the service of the Emperor of Mankind and dedicate his soul to the service of Chaos and its foul deities. Such corrupt Astartes normally belong to one of the 9 Traitor Legions that betrayed the Emperor during the ancient civil war called the Horus Heresy more than 10,000 standard years ago, while others come from Space Marine Chapters created long after the Heresy ended that have turned Renegade. Chaos can corrupt Astartes of any time and place just as its siren call leads many lesser men to their damnation.
Imperial Guard
The Imperial Guard is the largest military force of the Imperium of Man and also serves as the Imperium's first line of defence from the myriad threats which threaten the existence of the human race in the late 41st Millennium. It is comprised of countless billions of men and women -- hundreds of thousands of different regiments, supported by a vast array of light and heavy armoured vehicles that provide the Guard's primary offensive punch. They are usually the first Imperial force to respond to a threat if a planet's Planetary Defence Force (PDF) fails to suppress it. They also garrison major locations of strategic or cultural interest to the Imperium and are often found in defensive roles. The Imperial Guard is often referred to as the "Sledgehammer of the Emperor";
Kroot
The Kroot are a species of savage humanoids who are a member species of the Tau Empire who evolved from avian creatures. Kroot are tall aliens (a good half-meter taller than most humans), their avian ancestry giving them a bird-like beak and long quills protruding from their heads like hair. Smaller quills, possibly the evolutionary remnants of feathers, can be found scattered over their bodies.
Tyranids
The Tyranids are a species of terrible xenos that is actually a space-faring ecosystem dedicated solely to its own propagation and evolutionary advancement. The Tyranids collectively form a monstrous superorganism that travels the universe in their great Hive Fleets of biomechanical Hive Ships, systematically consuming all other biomatter to enable its own rapid evolution and reproduction. All Tyranid organisms are Synaptic (psychically-reactive), and each Tyranid creature within a Hive Fleet shares in a communal Hive Mind, granting the ability for trillions of beings to communicate and organize instantaneously on a staggering scale.
Tau
The Tau are a young, humanoid and highly technologically-advanced intelligent race native to the Eastern Fringes of the Milky Way Galaxy who are fighting to expand their interstellar empire and a philosophical concept they call the Greater Good. The Tau claim to be a peaceful race when possible, asking if others will join their cause voluntarily instead of fighting. However, if their peaceful overtures are refused, the Tau may well decide to conquer a planet and add it to their growing interstellar empire for the greater good, searing the flesh from the bones of anyone who stands against their benign expansions. Tau society is divided into a number of castes, each responsible for managing a specific aspect of their society. The Tau's central motivating ideal is that everyone in their empire regardless of their species will work for the collective betterment of everyone else, an almost mystical philosophy they call the Greater Good.
Chaos Daemons
A Daemon, also known as a Neverborn amongst the Forces of Chaos, is an intelligent and usually malevolent entity of the Warp that is a living embodiment of Chaos. Daemons are collectively the greatest servants of the Chaos Gods and of Chaos itself as a universal force. They are created at the whim of one of the four major Chaos Gods from a fraction of the god's own power within the Immaterium and act as an extension of his will. A daemon's appearance and intrinsic character reflect the god's own nature. These daemons may be reabsorbed into the god's own psychic signature in the Warp at his whim.
Orks
The Orks, also called Greenskins, are a savage, warlike, green-skinned race of humanoids who are spread all across the Milky Way Galaxy. They share many features with Warhammer Fantasy Orcs (and were initially called Space Orcs to distinguish them). They are seen by their enemies (pretty much everyone else in the galaxy) as savage, warlike, and crude, but they are the most successful species in the whole galaxy, outnumbering possibly every other intelligent race, even Mankind (with the very plausible exception of the Tyranids, who are split between thousands of subspecies genetically engineered for specific purposes). However, this massive population of Orks is split into hundreds of tiny empires, often warring between themselves. It has been speculated that were the Orks ever to unite as a single racial entity, they would undoubtedly crush any opposition that would dare to stand against such a tsunami of green muscle. Luckily, the Orks enjoy killing each other every bit as much as they savour shedding the blood of the galaxy's other peoples.
Necrons
The Necrons are a mysterious race of robotic skeletal warriors that have lain dormant in their stasis-tombs for more than 60 million Terran years and who are the soulless creations and former servants of the ancient C'tan, the terrible Star Gods of Eldar myth. The Necrons are ancient beyond reckoning, predating even the birth of the Eldar. At long last, however, they are beginning to awaken from their Tomb Worlds, for the galaxy is ripe for the greatest harvest of sentient beings to feed the eternal hunger of the C'tan since the disappearance of the Old Ones 65 million standard years ago. The Necrons are a completely cybernetic humanoid species whose technological prowess is probably unmatched by any of the other intelligent races of the galaxy. Yet out of a desire for vengeance against the more fortunate long-lived ancient xenos race called the Old Ones, and the trickery of the godlike intelligences known as the C'tan, the Necrons shed their organic forms and lost all forms of compassion and empathy, becoming ruthless, undying killing machines who feed their endless appetite for the life energy of organic beings and whose different dynasties are determined to exert their mastery over the galaxy once more.
