Chaos Space Marines are the Imperium's most bitter foes – warbands of genetically augmented killers, clad in baroque armour and sworn to otherworldly forces, festooned with the battle scars and trophies of their treachery. This deck of Index: Chaos Space Marines cards will enhance your games from the moment you start playing Warhammer 40,000, giving you hands-on references to all the rules for your faction. The deck includes individual datasheets for every Heretic Astartes unit, detailing their profiles, wargear, options, and special abilities. You'll also find reference cards for the Heretic Astartes army rules – Dark Pacts and The Lost and the Damned – as well as the Slaves to Darkness Detachment, which includes five Enhancements, six Stratagems, and the Marks of Chaos rule. There's also an Armoury card, which details common weapons employed by the Heretic Astartes.
