An Age of Darkness has descended upon the galaxy. Horus Lupercal, Warmaster of the Emperor's armies, has turned against his gene-father and sent the Imperium spiralling into bloody civil war. Of the eighteen great Space Marine Legions, finest of all humanity's soldiers, fully half have sided with the traitorous Warmaster, while the remainder stand staunchly loyal to the Emperor. 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 Citadel and Forge World miniatures, and clash with fellow players in wargames of staggering tactical depth.
