On the thirteenth day of Secundus, the bombardment began... In the greatest betrayal the universe has ever known, the Warmaster Horus - once humanity's greatest general, now corrupted by Chaos - has turned against the Emperor and hurled the Imperium of Man into ferocious civil war. The galactic conflict has risen to its climax. The Warmaster's ruinous legions have assaulted Holy Terra itself, the Emperor's seat. Here the fate of humanity hangs in the balance during the greatest military campaign ever seen. In the Horus Heresy board game, this legendary battle unfolds across the razed plains of Terra and in the frozen orbit above. Deadly fighting ranges from the Emperor's golden Inner Palace to Horus's flagship, the Vengeful Spirit. Taking the side of either traitor or loyalist, two players control either fearless Space Marine legions or deviant Chaos Space Marines, mighty Titans, Imperial Armies both loyal and traitorous, and a fearsome array of other units, including the Emperor and Horus themselves. An innovative order and initiative system forces each side to carefully consider the commands they issue to their troops. A dramatic, card driven combat system incorporates escalating damage, gives players the opportunity to allocate resources between attack and defense, and brings to bear the unique special powers of each unit type, from fortification-destroying Titans to the perverse daemons of Chaos. Brother fights brother, and the universe hangs in the balance!Horus Heresy includes over 120 detailed miniature models including 10 plastic terrain pieces, and more than 200 cards to bring this sweeping conflict to life on a stunning map of the war-torn Terra. Horus Heresy is for 2 players, 13+ and takes about 2 hours to play.
