What is the Horus Heresy: Age of Darkness?
The Horus Heresy: Age of Darkness is a tabletop wargame immersing players in the brutal civil war that nearly shattered the Imperium of Man. Set roughly 10,000 years before the events of Warhammer 40,000, it depicts the conflict between the Loyalist forces and the Traitor Legions led by Horus. This era is characterized by large-scale warfare, complex political intrigue, and the immense power of the Primarchs.
The game utilizes a detailed ruleset, now comprehensively updated in the 1st Edition rulebook, offering a strategic and narrative-rich experience. Access to this ruleset is readily available through the Steam Workshop, providing a centralized hub for all necessary resources. It’s a period of galactic upheaval, where the fate of humanity hangs in the balance, and players can recreate iconic battles or forge their own destinies within this tumultuous age.
The Rulebook as a Replacement
The 1st Edition Horus Heresy: Age of Darkness rulebook serves as a direct replacement for the previous iteration, streamlining gameplay and resolving inconsistencies. It consolidates previously released FAQs for the 7th edition, eliminating the need for players to consult multiple sources. This updated version incorporates the Horus Heresy-specific army construction rules, moving away from the 7th edition standard and offering a more thematic approach to force organization.
This consolidation simplifies the gaming experience and ensures a unified ruleset. Players no longer need to navigate fragmented information, as the rulebook provides a complete and coherent foundation for their battles. The Steam Workshop offers access to this comprehensive collection, making it easily accessible to the community.
Key Changes from Previous Editions

Significant alterations distinguish the Age of Darkness rulebook from its predecessors, enhancing balance and refining core mechanics. Notably, the invisibility rule has been replaced, addressing concerns about its disruptive impact on gameplay and promoting more engaging engagements. Furthermore, adjustments have been made to the usage of melta-bombs, likely aimed at balancing their destructive potential and preventing overly dominant strategies.
These changes reflect direct community feedback, demonstrating a commitment to collaborative development. The integration of 7th edition FAQs ensures consistency, while the adoption of Horus Heresy army construction rules deepens the thematic immersion. These modifications collectively contribute to a more dynamic and strategically nuanced tabletop experience.
Incorporation of FAQs
A crucial aspect of the Age of Darkness rulebook is the comprehensive integration of previously released Frequently Asked Questions (FAQs) from the 7th edition. This consolidation streamlines gameplay by resolving ambiguities and providing clear guidance on rules interpretations. By directly incorporating these clarifications, the rulebook eliminates the need for players to consult separate documents, fostering a more cohesive and accessible gaming experience.
This approach ensures consistency and reduces potential disputes during matches. The inclusion of FAQs demonstrates a dedication to refining the ruleset based on player feedback and addressing common points of confusion. It represents a significant improvement over relying on scattered online resources, offering a definitive and readily available source of truth for all rules-related inquiries.
Army Construction Rules
The Horus Heresy: Age of Darkness rulebook departs from the 7th edition standard by implementing dedicated Horus Heresy army construction rules. This shift signifies a move towards a more specialized and lore-accurate approach to building forces for the tabletop. Players can now assemble their armies based on the specific organizational structures and unit compositions prevalent during the tumultuous era of the Horus Heresy.
This system allows for greater customization and reflects the unique characteristics of each Legion. The new rules encompass detachment types, force organization charts, and wargear options tailored to the 30th Millennium setting. This detailed approach enhances the immersive quality of the game, enabling players to recreate the epic battles of the civil war with greater fidelity.
Balance Changes Based on Community Feedback
The Age of Darkness rulebook incorporates several balance adjustments directly responding to community feedback, demonstrating a commitment to refining the gameplay experience. Notably, the controversial invisibility rule was replaced, addressing concerns about its disruptive impact on tactical engagements. This change aimed to promote more dynamic and visible battlefield interactions, fostering a more engaging experience for all players.
Furthermore, adjustments were made to the usage of melta-bombs, likely to address issues of excessive power or tactical inflexibility. These modifications reflect a dedication to ensuring a fair and balanced playing field, where strategic decision-making and skillful execution are paramount. The implemented changes strive to create a more competitive and enjoyable environment for Horus Heresy enthusiasts.
Invisibility Rule Modification
A significant alteration within the Age of Darkness rulebook centers around the complete removal of the previous invisibility rule. This decision stemmed directly from community feedback, indicating the rule was perceived as problematic and disruptive to balanced gameplay. Players frequently expressed concerns that invisibility created frustrating scenarios, hindering tactical engagements and diminishing the strategic depth of battles.
The removal of invisibility aimed to foster a more transparent and dynamic battlefield, encouraging active scouting, positioning, and direct confrontation. By eliminating this mechanic, the rulebook promotes engagements based on skillful maneuvering, accurate shooting, and effective use of cover, rather than relying on concealment. This change reflects a commitment to a more engaging and competitive experience.
Melta-Bomb Usage Adjustments
The Horus Heresy: Age of Darkness rulebook implemented changes to the usage of melta-bombs, responding to concerns about their overwhelming effectiveness. Previously, melta-bombs were considered excessively potent, capable of reliably destroying even heavily armored targets with relative ease. This led to a perceived imbalance, where players frequently prioritized melta-bombs over other weapon options.
The adjustments aimed to refine the role of melta-bombs, making them powerful but situational. These modifications likely involved alterations to their range, damage output, or specific targeting restrictions. The goal was to maintain their anti-tank capabilities while preventing them from becoming an automatic, one-shot solution for eliminating any enemy unit. This change encourages more diverse tactical approaches.

Understanding the Core Rules

The core mechanics encompass movement, range, combat sequences, and morale/leadership, forming the foundation of gameplay within the Horus Heresy: Age of Darkness.
Core Mechanics Overview
The Horus Heresy: Age of Darkness rulebook centers around a robust system governing unit actions and battlefield interactions. Core to this is the sequencing of phases, dictating when units can move, shoot, charge, and engage in close combat. Movement is measured in inches, influencing a unit’s tactical positioning and ability to reach objectives. Range determines the effective distance at which weapons can target enemies, demanding strategic deployment.

Combat resolution involves dice rolls modified by unit statistics and special rules, simulating the chaos of war. Morale represents a unit’s ability to withstand casualties and maintain cohesion, while leadership influences their effectiveness under pressure. These interconnected mechanics create a dynamic and immersive tabletop experience, demanding careful planning and tactical execution from players seeking victory amidst the galactic conflict.
Movement and Range
Within the Horus Heresy: Age of Darkness, movement is meticulously measured in inches, directly impacting tactical positioning and objective control. Units possess varying movement characteristics, influencing their speed across the battlefield and ability to exploit terrain. Range, equally crucial, defines the maximum distance at which a weapon can effectively target an enemy unit.
Understanding these parameters is vital for strategic deployment and maximizing firepower. Different weapon types boast diverse ranges, demanding careful consideration of engagement distances. Terrain features can further modify movement and range, creating tactical challenges and opportunities. Mastering these core mechanics allows players to dictate the flow of battle and outmaneuver their opponents in the pursuit of galactic dominance.
Combat Sequence
The Horus Heresy: Age of Darkness employs a structured combat sequence, ensuring a fair and methodical resolution to engagements. This sequence typically begins with determining which units can shoot, followed by the shooting phase where attacks are resolved based on weapon skill, ballistic skill, and target characteristics.
Subsequently, the assault phase initiates close combat, utilizing weapon skill and strength to inflict casualties. Critical aspects include determining hits, armor penetration, and damage infliction. Morale checks follow, assessing a unit’s resilience under fire. This systematic approach guarantees a balanced and engaging combat experience, demanding strategic decision-making and tactical acumen from players throughout each turn.
Morale and Leadership
Morale and leadership are pivotal components within the Horus Heresy: Age of Darkness, profoundly impacting unit cohesion and battlefield effectiveness. Units subjected to casualties or adverse circumstances undergo morale checks, potentially resulting in disordered or even routed states. Leadership plays a crucial role in bolstering morale, with effective commanders mitigating the risk of units breaking under pressure.
The rulebook details specific mechanics for determining morale checks, factoring in unit type, casualties sustained, and the presence of inspiring leaders. Maintaining unit morale is essential for sustained combat performance, as broken units can significantly disrupt battle plans. Strategic deployment of leaders and careful consideration of potential morale impacts are vital for success.

The Horus Heresy Setting & Lore
The setting draws heavily from Egyptian mythology, featuring deities like Horus, Osiris, Isis, Nut, Hathor, Nephthys, and Set, interwoven into the narrative’s rich tapestry.
The Egyptian Origins of Horus

Horus, a central figure in Egyptian mythology, is depicted as the falcon-headed god embodying the sun, sky, and kingship. His enduring presence spans millennia, manifesting in diverse roles throughout ancient Egyptian beliefs. Most famously, he’s recognized as the son of Osiris and Isis, destined to reclaim his father’s rightful throne after a period of usurpation.
This narrative of succession and righteous vengeance forms a cornerstone of Horus’s mythology. While Greek sources mention Horus the Elder as a sibling to Osiris, Isis, Set, and Nephthys, non-Greek accounts omit him from the lineage of Nut and Geb. The familial relationships are complex, with Isis and Nephthys being married even before their births, adding layers to the divine family dynamics.
Horus’s story isn’t merely about reclaiming a throne; it’s a cosmic struggle between order and chaos, light and darkness, mirroring themes prevalent within the Horus Heresy narrative itself.
Horus: God of Sun, Sky, and Kingship
Horus’s multifaceted nature positions him as a paramount deity in the Egyptian pantheon, representing the life-giving power of the sun and the vast expanse of the sky. He isn’t a static figure, but rather appears in numerous forms across thousands of years of worship, adapting to evolving beliefs and societal needs.
As the god of kingship, Horus embodies legitimate rule and divine authority. His claim to the throne, inherited from his father Osiris, establishes a precedent for rightful succession and the restoration of order. This concept resonates deeply within the Horus Heresy, mirroring the conflict over the Imperium’s leadership.
His role extends beyond mere sovereignty; Horus is a protector, a warrior, and a symbol of hope, constantly battling against the forces of chaos to maintain cosmic balance. This struggle defines his mythology and provides a powerful archetype for the events unfolding in the Age of Darkness.
The Role of Osiris and Isis
Osiris, the murdered and resurrected god, represents death, the afterlife, and rebirth – a cycle central to Egyptian cosmology. His tragic demise at the hands of Set and subsequent restoration by Isis establishes a narrative of overcoming adversity and achieving immortality, themes echoed in the Horus Heresy’s grand conflict.
Isis, Osiris’s devoted wife, embodies magic, motherhood, and healing. Her unwavering dedication and powerful sorcery were instrumental in resurrecting Osiris, solidifying her position as a protector and a symbol of feminine strength. She is often depicted as the ideal mother and wife.
Together, Osiris and Isis form a divine couple whose story profoundly influenced Egyptian beliefs about life, death, and the cosmos. Their relationship serves as a foundational myth, shaping the understanding of kingship, family, and the enduring power of love and loyalty.
Nut: Goddess of the Sky and Mother of Deities
Nut, the powerful Egyptian goddess, personifies the vast expanse of the sky, arching over the earth and protecting it from chaos. Her body is depicted as a star-studded canvas, representing the celestial realm and the mysteries it holds. She plays a crucial role in the daily journey of Ra, the sun god, swallowing him each night and giving birth to him anew each morning.
As the mother of Osiris, Isis, Set, and Nephthys (and, in some accounts, Horus the Elder), Nut is the progenitor of a generation of influential deities. This maternal role establishes her as a foundational figure in Egyptian mythology, responsible for bringing forth the gods who would shape the world.
Her very being supports Ra and prevents the primordial waters of Nun from engulfing the earth, highlighting her essential function in maintaining cosmic order.

Hathor: Goddess of Love, Marriage, and Motherhood
Hathor, visually represented with the head of a cow, embodies the nurturing aspects of Egyptian divinity, presiding over love, marriage, and motherhood. Her influence extends beyond domesticity, encompassing joy, music, and dance, making her a multifaceted and beloved goddess.
Throughout millennia of worship, Hathor assumed diverse mythological roles, demonstrating her adaptability and enduring significance. She is known for both benevolent acts, like healing Horus, and fierce displays of power, such as massacring the enemies of Ra, showcasing her complex nature.
Furthermore, Hathor provides nourishment to the deceased in the afterlife, offering comfort and sustenance on their journey. This role solidifies her position as a protector and guide, extending her care beyond the realm of the living.
Nephthys and Set: Siblings and Spouses
Nephthys, the youngest offspring of Nut and Geb, shares a unique familial bond with Set, being both siblings and spouses before birth. This unconventional relationship highlights the complex dynamics within the Egyptian pantheon and challenges conventional notions of kinship.
While her siblings, Osiris, Horus the Elder, and Isis, are prominently featured in many narratives, Nephthys often occupies a more subtle role. However, her connection to Set is crucial, representing a powerful, albeit often misunderstood, alliance.
It’s important to note that Horus the Elder appears exclusively in Greek sources, absent from native Egyptian accounts of Nut and Geb’s progeny. This distinction underscores the influence of cross-cultural interpretations on mythological understanding.
