The galaxy burns! Warmaster Horus has betrayed the Emperor and plunged the Imperium into civil war! An age of darkness has descended upon the galaxy. It is a war of brother against brother, Space Marine against Space Marine, which has seen the might of the Imperium's vast armies turned upon itself in a cataclysm of fire and blood.

In Warhammer: The Horus Heresy, you will pit mighty armies of superhuman warriors against each other in apocalyptic tabletop battles. Choose your favoured Legion – from the knightly Dark Angels to the duplicitous Alpha Legion – build your own army from a range of spectacular miniatures, and clash with fellow players in wargames of staggering tactical depth. The tale of the Horus Heresy is the bedrock of Warhammer 40,000's rich history, and this boxed set is the ideal first step to joining the epic conflicts that reshaped the galaxy.

The Warhammer: The Horus Heresy – Saturnine boxed set contains a treasure trove of content, including a rulebook detailing the lore and background of the galaxy-shaking civil war, gorgeous photography and art, and the core rules you need to play the game. The box also contains 50 plastic miniatures – including an imposing Saturnine Dreadnought and a host of MKII "Crusade" armoured Space Marines – allowing you to build two opposing forces for out-of-the-box play, or begin building a Legion force all your own. Alongside all of this, you'll get game accessories and rules reference materials to immerse yourself in the worlds of the Age of Darkness. Whether you prefer building, painting, in-depth narrative play, or balanced matched play, this box will support your journey through the 31st Millennium.
