Journal Tactica: Zone Mortalis

Zone Mortalis: Journal Tactica

Not every battle of the Horus Heresy is fought across open battlefields. Many of the war's fiercest engagements take place deep within fortress complexes, hive cities, underground installations, and sprawling industrial facilities where narrow corridors and sealed chambers leave little room for armored vehicles or long-range fire support. In these confined environments, close-quarters combat determines the fate of entire campaigns.

Master Close-Quarters Warfare

This Journal Tactica supplement expands Warhammer: The Horus Heresy with the complete Zone Mortalis Core Rules and the Clearance Protocol Mission Pack. Designed for intense battles fought in enclosed environments, it introduces new terrain rules, missions, and unit options tailored to brutal fighting in tight spaces.

Whether you're recreating iconic Horus Heresy engagements or designing your own campaigns, this supplement provides everything needed to bring claustrophobic urban warfare to the tabletop.
