Eventually, White Dwarf provided proper 'army lists,' which could be used to create larger and more coherent forces than were possible in the main rulebook.ДЄ few elements of the setting ( bolters, Frag Grenades, Terminator Armour) can be seen in a set of earlier wargaming rules called Laserburn produced by Tabletop Games. In addition, supplemental material was continually published in White Dwarf magazine, making and providing rules for new units and models. Much of the composition of units was determined randomly, by rolling dice. This original version came as a very detailed, though rather jumbled, rulebook, making it most suitable for fighting small unit skirmishes. Game designer Rick Priestley created the original rules set and the Warhammer 40,000 universe. The first edition of the game, Warhammer 40,000: Rogue Trader, was published in 1987.

The mood of the franchise is concisely summed up in the slogan: 'In the grim darkness of the far future, there is only war.'

Mankind is xenophobic, fascist and tyrannical at its best in this time, though also for good reason considering the sheer hostility of the universe that Humanity inhabits. There are no unambiguously 'good' factions for example, the Imperium of Man, which most players might be expected to sympathise with, is a corrupt, uncaring, and stagnant interstellar government that dominates the Milky Way Galaxy. The universe of Warhammer 40,000 is strongly dystopic, using many elements from Gothic, dark fantasy and Lovecraftian literature.

The game depicts combat between the armies of the fictional universe of the 41st Millennium using 28 mm scale (approximately 1:65) miniature figurines which represent futuristic soldiers, creatures and vehicles of war. Warhammer 40,000 is the science fantasy companion to the dark high fantasy world of Warhammer Fantasy and Warhammer Age of Sigmar, and originally shared many of the same game mechanics and some of the setting elements with those properties. The intellectual property also has expanded in recent years to include other related tabletop miniature games, video games, novels and animated features. Warhammer 40,000 (informally known as Warhammer 40K, WH40K, W40K or just 40K) is a science fantasy tabletop miniature wargame, produced by Games Workshop.
