Take to the shattered, war-torn battlefields of the Garmon Cluster with this expansion book for Warhammer: The Horus Heresy – Legions Imperialis. This 128-page hardback book explores the origins of the terrible clash that would later become known as the Great Slaughter of Beta-Garmon, and allows you to fight massive battles and bloody campaigns set within that apocalyptic conflict.

The Thunderhawk Gunship fulfils a number of roles within the Legiones Astartes, but primarily acts as a drop ship, soaring through both atmosphere and void space to deliver its deadly cargo of Space Marines. It is also a formidable weapons platform in its own right, however, equipped to scour landing zones and engage enemy aircraft

The Reaver Titan is one of the most ubiquitous and destructive classes of Battle Titan, a gargantuan war machine that forms the heart of the Titan Legions, holding the line or leading the charge as their Princeps demand. Whether unleashing awesome thermal blasts from a melta or volcano cannon, spitting beams of death from a turbo-laser destructor, or closing in to shred heavy armour with a roaring chainfist, the Reaver leaves enemies with one choice: flee or die.

Warhounds are the smallest class of ‘true’ Titan, classified within the De Bellis Titanicus as ‘Scout Titans’ in reference to their common operational role as vanguards to larger Titan battle groups, or support elements for lesser ground forces. A Warhound's sheer scale and power is enough to turn the tide of most battles – but when facing enemy Titans, they must rely on manoeuvrability and pack tactics to bring down their larger counterparts.

The Rhino is the most widely used armoured personnel carrier in the Imperium. Based upon ancient STC technology, the fundamental design is robust, reliable, and easy to maintain, with an adaptive power plant that can run off a wide variety of fuels. Within the Space Marine Legions, the Deimos pattern was the most widespread, serving as the basic armoured transport available to the Legiones Astartes and the foundation on which a number of other war machines were based.

Dire Wolf Heavy Scout Titans are sturdier and more heavily armoured than their Warhound cousins, and function as ambushers in Legio Titanicus battlegroups. Dire Wolves hunker down in forward positions to ambush and obliterate key targets with precise shots from their primary dorsal weapon, while their pintle-mounted arm weapons offer some defence against lesser targets, allowing the Heavy Scout Titans to focus on lining up a firing solution.

Warmaster Heavy Battle Titans are the embodiment of the Omnissiah's wrath. Once hidden away from prying eyes, these war machines have been unleashed in the cataclysmic days of the Horus Heresy. Though few in number, the thunderous tread of a Warmaster is an omen of impending doom, for little can stand against their fury.

Spartan Assault Tanks carry large numbers of Space Marines into the very heart of the battle. Mounting armaments comparable to the Legion’s super-heavy armoured vehicles and protected by heavy layers of armour plating, these tanks are considered by many to be akin to a mobile fortress.

The Kratos Heavy Assault Tank is based on an Ancient Terran pattern, first fielded during the Unification of Old Earth. Redesigned after the Emperor's treaty with the Lords of Mars to serve as the spearhead of the Great Crusade, it excels as a line-breaker and foe hammer. Their steady, inexorable advance provides an indomitable core to any assault by the Legiones Astartes, enforced by a barrage of overwhelming firepower.

Warhounds are the smallest class of ‘true’ Titan, classed as Scout Titans in reference to their common operational role as vanguards to larger Titan battle groups, or support elements to lesser ground forces. When confronting enemy god-engines, Warhounds must rely on their speed, manoeuvrability, and pack tactics to bring down their larger counterparts.

Across the war-torn worlds of the Age of Darkness, massive armies battle amongst ruined cities. Nowhere is the cost of war more evident than areas where entire blocks have been bombarded, or suffered the tread of mighty Titans.

This box builds six epic scale Land Raider Proteus tanks for your games of Legions Imperialis. These ancient variants are used by all Legiones Astartes, where their heavy armour, lascannons, and transport ability makes them fantastic all-around workhorses. Land Raiders are an ideal transport for Space Marine infantry, getting your elite troops where they need to be in one piece. You'll find a variety of options for the top hatch, allowing you to mix up the way your individual tanks look.

Horus Lupercal, Warmaster of the Emperor's armies, has turned upon his gene-father and sent the Imperium spiralling into bloody civil war. Half of the great Space Marine Legions have sided with the traitorous Warmaster, and countless cohorts of the Solar Auxilia, Knight Households, and Titan Legions march at his side. Now brother fights brother as the Imperium's vast armies tear one another apart in a cataclysm of fire and blood. An age of darkness descends, the likes of which have never been witnessed before.

The Solar Auxilia are well equipped to engage in every theatre of battle, against every type of foe. Their adaptability is due in part to their training, but also the advanced wargear they bring to the front. When in need of heavy support from weapons too large for infantry to carry, their Tarantula and Rapier weapons platforms add additional firepower, while remote-controlled Cyclops tanks can be sent in to clear bunkers or even destroy heavy tanks.

The Warbringer Nemesis Titan serves the Collegia Titanica in the role of heavy fire support. It mounts a single Warlord-scale weapon on its upper carapace and Reaver-scale weapons on its arms – sacrificing the speed, armour and manoeuvrability of a conventional Battle Titan in favour of firepower far in excess of its size. With a Mori quake cannon launching world-shaking shells of arcane power, the Warbringer Nemesis is a sight to inspire dread in all but the most battle-hardened enemy Princeps.

The Knight Questoris is the most common suit of Knight Armour extant in the Imperium during the Age of Darkness, serving as the mainstay of Household forces and configured with a myriad of different armaments. Questoris Knights are frequently fielded in Lances, consisting of multiple noble Scions operating in concert.
