Legions: Rise of the Dark Mechanicum

This 128-page hardback book provides a detailed history of the rift that split the Mechanicum, exploring the rise of the Dark Mechanicum and the Doom of Magma City, the largest conflict of the war. It includes rules for both the loyal Mechanicum and the traitorous Dark Mechanicum, along with their Formations and Detachments. The book also features a campaign system for linking Legions Imperialis battles, including an Escalation Campaign, rules for three Formations of Legend, and army lists for Collegia Titanica and Questoris Familia forces. A copy of the Warhammer: The Horus Heresy – Legions Imperialis Rulebook is required to use this content.
