Warhammer 40,000 is a tabletop miniature wargame published by Games Workshop. It is set in the 41st Millennium — a far-future Gothic science fiction universe where a declining human empire called the Imperium of Man fights on every front against alien races, ancient machine warriors, and the corrupting force of Chaos. The tone is deliberately grim: the tagline "In the 41st Millennium, there is only war" is not irony. It is the premise.

What makes Warhammer 40K distinct from most other games is that the pieces are not tokens or cardboard standees. They are plastic miniature figures — soldiers, vehicles, creatures, and war machines — that you clip from a sprue, glue together, prime, and paint yourself. The models are the hobby. Many people who play Warhammer 40K spend more time on their workbench than at the game table, and they would not have it any other way.
