This 48-page softcover supplement contains:

• In-depth Lore: Detailing the Skitarii Battle-Pilgryms and their role within the Mechanicum, as well as how the horror of the Horus Heresy split even these stoic warriors between loyalty to the Fabricator General and the wider Mechanicum.
• Additional Missions: The Vaults of Tharsis Legendary Mission and the Relic Hunt Missions Pack, featuring fast-paced missions to recover ancient weapons and devices long thought lost.
• Skitarii Army List: Rules for using Skitarii Battle-Pilgrym Marshals, Skitarii Battle-Pilgrym Corpus, Bonepicker hosts, Skitarii Triaros Armoured Conveyor, Skitarii Karacnos Assault Tank, Skitarii Krios Battle Tank, and Skitarii Krios Venator Tank Destroyer in battles, including additional faction rules and new weapons to represent these fearsome warriors on the battlefield.

You will need a copy of the Warhammer: The Horus Heresy – Age of Darkness Rulebook and Liber Mechanicum, both available separately, to make full use of this gaming supplement.
