In this article, we’ll guide you through absolutely everything you need to know, from understanding the factions to picking the perfect Chaos Space Marines miniatures. Let’s dive in!

Discover the Lore of Chaos Space Marines

The Chaos Space Marines are no doubt one of the iconic factions to feature in Warhammer 40k. Their story is filled with betrayal, corruption, and bitter vengeance.

Once loyal servants to the Emperor, these warriors were cast into the Warp following a rebellion during the Horus Heresy, which led to a deep devotion among the Space Marines to the dark gods of Chaos, and to fighting against the Imperium for their fallen brothers-in-arms.

These former warriors are now powerful agents of Khorne, Nurgle, Tzeentch, and Slaanesh, and each Chaos god offers unique powers that shape the playstyle of their followers.

• Khorne: The god of war and bloodshed. His followers, like the World Eaters, focus on brutal close combat.
• Nurgle: The god of decay and disease. Death Guard armies are resilient and difficult to destroy.
• Tzeentch: The god of change and sorcery. The Thousand Sons use powerful psychic abilities to manipulate the battlefield.
• Slaanesh: The god of excess and pleasure. Emperor’s Children embrace perfection and indulgence.

Now that we understand the rich lore behind the Chaos Space Marines, let’s look at the top armies you can build with this faction.
