Members of the Adeptus Mechanicus are fanatical worshipers of the Machine God of Mars. With ritual and reverence, for thousands of years the hooded priests of the Cult of the Machine have managed the fabrication, maintenance, and preservation of Humanity's surviving technological wonders. Led by Tech Priests whose weak organic flesh has been replaced by metallic prosthetics, the armies of the Adeptus Mechanicus fight to defend the forge worlds and traverse the galaxy in search of ancient archaeotech.

Within the ranks of the Cult of the Machine are cohorts of disciplined cybernetic soldiers, towering robot warriors, and battle minions. They wield a wide array of exotic weapons capable of obliterating enemies with volleys of radioactive munitions or incinerating them with blasts of fiery energy. Those who seek to sabotage the divine work of the Omnissiah must face the power of this ruthless mechanical war machine, devoid of compassion and remorse.

The Codex: Adeptus Mechanicus is the invaluable guide to collecting and playing the Adeptus Mechanicus. Within its pages you will find the rules you need to play an Adeptus Mechanicus army in your games of Warhammer 40,000 (including rules for the Crusade narrative campaigns and Battle Patrol skirmishes), as well as information on the mysterious techno-dogmas of this Cult, on the bizarre bionic prosthetics, the most important forge worlds and the role of the Adeptus Mechanicus in the Imperium.
