Journal Tactica: Zone Mortalis brings the brutal close-quarters warfare of the Horus Heresy to life with a complete rules expansion for fighting desperate battles inside fortress complexes, hive cities, underground installations, and sprawling industrial facilities. Packed with new battlefield rules, missions, unit profiles, and tactical options, this supplement delivers a fresh way to experience the Age of Darkness.

• Official Horus Heresy Supplement – Introduces the complete Zone Mortalis rules for Warhammer: The Horus Heresy.
• Fight in Claustrophobic Battlefields – Battle through corridors, chambers, and fortified installations where every decision matters.

• Expanded Army Options – Features five new unit profiles for Legiones Astartes, Solar Auxilia, and Mechanicum armies.

Not every battle of the Horus Heresy was fought across vast open plains or beneath the guns of mighty Titans. Many of the conflict's most desperate engagements took place deep within fortress networks, hive cities, orbital stations, and underground defence complexes where tanks could not advance and artillery offered little support. Victory depended upon disciplined infantry, elite assault troops, and relentless close-quarters combat.

Journal Tactica: Zone Mortalis provides the complete rules required to recreate these brutal engagements. New battlefield mechanics introduce corridors, chambers, blast doors, confined spaces, and specialised interactions that fundamentally change how Warhammer: The Horus Heresy is played, rewarding careful movement, tactical positioning, and aggressive assaults.

The included Clearance Protocol Mission Pack expands gameplay with six new missions, additional objectives, deployment options, and primary detachments specifically designed for fighting within enclosed environments. The supplement also introduces five new unit profiles ideally suited to close-quarters warfare, providing fresh tactical opportunities for several of the game's most popular factions.

This 48-page softcover supplement includes:

• Zone Mortalis Battlefields – Rules for corridors, chambers, doorways, confined spaces, and specialised terrain.
• Zone Mortalis Core Rules – Complete rules for enclosed battles, including Zone Mortalis Reserves, Advanced Reactions, and Cogitator Terminals.
• Clearance Protocol Mission Pack – Six new missions with new objectives, deployment maps, and primary detachments.
• Additional Unit Profiles – Veteran Breacher Squads, Veteran Despoiler Squads, Veletaris Raider Sections, Auxilia Combat Technician Sections, and the Castellax Infernus Maniple.

Please Note: You'll need a copy of the Warhammer: The Horus Heresy – Age of Darkness Rulebook, along with Liber Mechanicus, Liber Astartes, Liber Hereticus, and Liber Auxilia, all available separately, to make full use of this supplement.
