About Chaos Space Marines — Lore & How They Play
The Lore
The Chaos Space Marines are the Imperium's original sin: the traitor Legions and renegade Chapters who followed Horus into damnation, and their inheritors ten thousand years on. From the Black Legion of Abaddon the Despoiler to a hundred lesser warbands, they are everything the Astartes are — unbound by oath, conscience or restraint.
Each warband bargains with the Dark Gods on its own terms, taking marks, mutations and daemon-gifts as payment for atrocity. The Long War is their religion, and its only commandment is vengeance.
On the Tabletop
The most flexible force in the game's dark half: Chaos Space Marines mix durable Astartes infantry, daemon engines, cultist chaff and devastating characters into whatever shape you fancy, with marks of Chaos tuning units toward blood, filth, sorcery or speed.
They fight best in the mid-board — arrive in force, trade favourably, and let Dark Pacts sharpen the rolls that matter. If you want the Space Marine toolkit with the safety catch filed off, start here.
Chaos Space Marines are the Traitor Legions and renegades who turned on the Emperor ten thousand years ago and never looked back: Black Legion, Night Lords, Iron Warriors, Red Corsairs and more. Spikes, daemon engines, cultists and every ounce of bad attitude in Warhammer 40,000, with total freedom to build your own warband.
