Liber Mechanicum – Forces of the Taghmata Army Book (English)

This 152-page hardcover book is an essential reference for anyone looking to field a Mechanicum army in Warhammer: The Horus Heresy. Inside, you’ll find all the rules you need to organize and deploy a force of battle-automata, fanatical tech-adepts, and monstrous war machines—whether Loyalist or Traitor. The book includes unit profiles, Detachments, Equipment, and the distinct faction mechanics that set the Mechanicum apart, including the Major Techno-Arcana, which represent different branches of the Cult’s martial philosophy.

It also features rules for the Machina Malefica—Warp-tainted constructs twisted by dark energies—as well as the esoteric Cybertheurgic Rites used by the Mechanicum to dominate the battlefield in strange and terrifying ways. The book is richly illustrated with color schemes, heraldry guides, and a showcase of beautifully painted miniatures. To make full use of this supplement in your games, a copy of the Warhammer: The Horus Heresy – Age of Darkness Rulebook (sold separately) is required.
