Far from Terra, the Horus Heresy raged in the darkest places of the Imperium – and some of the brightest. The 500 Worlds of Ultramar were a beacon of hope and civilisation, and one that the Traitors hoped to tear down as they waged a Shadow Crusade across the region. In response, the Imperial Loyalists forged their own Crusade of Iron and brought the battle to their enemies.

Discover the secrets of the Shadow Crusade and the Crusade of Iron in this 97-page hardback supplement for Adeptus Titanicus, alongside a host of new rules to use in your games. Harness the psychic might of the Ordo Sinister and devastate your foes with warp-spawned powers. Add new weapons to your god-machines and use them to lay low your enemies. Try out new Stratagems in a host of narrative missions based on the Crusade of Iron. Experience the might of six new Titan Legions and six Knightly Houses, each with their own additional rules. And wage war across a sub-sector with detailed campaign rules that allow you to forge a battlegroup and maintain it across your games. Each victory will add to your roll of honour and increase your power, while each loss will leave you with decisions to make as you use your resources on repairing damaged Titans and keeping your grip on worlds as your foes try to seize them from you.
