Shadow War: Armageddon – Rulebook is an expansion for Shadow War: Armageddon released in 2017 for 2 players, 30–120 minutes per game, and ages 12 and up. Its main mechanics are Variable Player Powers, Dice Rolling, and Modular Board.
Shadow War doesn’t need a copy of the Warhammer 40,000 rules to play – it’s effectively a totally separate game, but sharing the setting and some miniatures. More than just a reprint of the book that originally appeared in the boxed game, this 200-page rulebook contains a wealth of new content. The main update is the inclusion of all the factions, previously only available as PDF downloads. By popular demand, two new factions have been added too – the fanatical Battle Sisters of the Adepta Sororitas, and the grim warbands of the Inquisition. This is a great book for those of you out there with an existing Warhammer 40,000 collection you’d like to play with in a different way, or for anyone who wants a way to play games with a small skirmish force while they build towards a bigger army. —descripiton from the publisher
