The Knight Questoris is the most prominent variety of Knight Armour on the battlefields of the Horus Heresy, striding forth alongside the Legiones Astartes, Taghmata Omnissiah, and in the great armies of Knight Households. Such was its popularity amongst the noble scions of the Questoris Households that it was reconfigured in myriad ways with weapon options and hull augments, and given names such as Paladin, Errant, Warden, Gallant, and Crusader to reflect their traditions, lineage, and fighting styles.

Sky-hunters are feared strike units, mounted atop sophisticated and powerful jetbikes. These high-speed craft are more akin to compact aircraft than ground bikes – propelled across the battlefield by jet engines with grav-impellor assistance, they can maintain great speeds for extended periods of low-altitude flight. The jetbike's lift-strength is enough to carry an armoured Space Marine and his wargear along with a variety of heavy weapons mounts and stocks of ammunition, giving the Sky-hunters access to extremely potent, highly mobile firepower.

This multipart plastic kit builds one Legion Scorpius, a mobile artillery piece built on the Deimos-pattern chassis. This tank's turret-mounted missile system is loaded with rotary racks of explosive rockets, ready to saturate whole battlefield zones with a whirlwind of shrapnel and flames. Its launchers can be assembled at a variety of angles, to suggest a devastating volley of direct fire or an arcing salvo of munitions that will wipe out all but the heaviest infantry.

Outside the loyalist Space Marine Legions and the Cult Mechanicum, the Emperor wields forces which are loyal only to him. The Legio Custodes guard the Emperor's person, while the Sisters of Silence stand watch over the Black Ships. The Solar Auxilia are the elite spearhead of the Imperial Army, exemplars of mortal soldiery, while the Divisio Assassinorum is the Emperor's culling blade, aimed at the neck of any foolish enough to imperil his grand dream of Unity.

The Predator is perhaps the best known and most widespread variant of the basic Rhino chassis, equipped with superior armour protection and firepower, but sacrificing the Rhino’s troop transport capacity entirely. The Predator Support Tank is designed to field a wide variety of armament configurations, allowing it to excel in specific battlefield roles.

The Land Raider is regarded by many as the finest armoured fighting vehicle of its class in the Imperium’s arsenal, and is the mainstay battle tank of the Space Marine Legions. It is a phenomenally powerful war machine, its multi-layered composite armour and reinforced hull all but impervious to even heavy weapons, being a sealed unit designed to resist enemy attack from any approach. Intended to serve in almost any environment as both war machine and exploration vehicle, it can operate freely in war zones ranging from acid swamps to rad-deserts without any noticeable impediment to its performance, and can even operate in hard vacuum, ensuring there is no open battlefield on which its armoured wrath cannot be unleashed.

Heavy Support Squads provide the Legiones Astartes with mobile, infantry-portable firepower sufficient to bring down hordes of enemy troops or smash armoured vehicles apart with withering hails of fire, combining devastating armaments with all the flexibility of a footsoldier. Heavy flamers project a roaring torrent of burning promethium capable of incinerating infantry and flushing foes from cover, while multi-meltas reduce enemy tanks to molten slag with a flash of energy, and plasma cannons unleash volatile blasts of superheated matter.

Heavy Support Squads provide the Legiones Astartes with mobile, infantry-portable firepower sufficient to bring down hordes of enemy troops or smash armoured vehicles apart with withering hails of fire, combining devastating armaments with all the flexibility of a footsoldier. Volkite culverins emit scorching heat rays that burn through swathes of infantry, while versatile autocannons spit shells that shred troops and light vehicles alike. Lascannons are the most powerful laser weapons available to Legionaries, firing devastating beams to punch clean through tank armour.

The Predator is perhaps the best known and most widespread variant of the basic Rhino chassis. Augmented with superior armour and firepower, it entirely sacrifices the Rhino’s troop transport capacity in favour of ammunition and generators for its formidable weapon systems. The result is an effective and versatile tank of the line, with an excellent balance of speed, firepower, and protection. The Predator's robust design can field a wide variety of armament configurations – the Legiones standard is a rapid-firing turret mounted autocannon, but other configurations include a powerful heavy lascannon, or more exotic grav and volkite weapons.

The battles of Warhammer: The Horus Heresy are rife with swift Reactions, mighty Warlords, and forbidden Psychic Powers. This handy deck of reference cards makes it easy to keep track of new rules and mechanics, so you can focus on your strategy. These cards will ensure you can take full advantage of the new Reaction system – they work as both a reminder to use them, and a rules reference for you and your opponent.

Terminator suits are the ultimate in personal armour technology, gifted to the finest veteran forces of the Legiones Astartes. Squads clad in Terminator armour become devastating frontline assault units, able to withstand the heaviest enemy fire and deliver a ruthless hammer blow to crush their foes. Tartaros armour is perhaps the most advanced form of Terminator suit ever designed – offering greater durability and protection than power armour, while sacrificing none of its mobility.

Praetors are the mightiest warriors and battle-leaders of the Space Marine Legions, second only to the god-like Primarchs in martial skill and generalship. Amongst their ranks can be found chapter masters and lord commanders, captains and khans, warsmiths and jarls, as the traditions of their Legions dictate. Each is a vastly experienced warrior and warlord who has writ for themselves a legend in blood, and carries into battle the finest wargear and weapons known to humanity, leading hosts that have conquered worlds unnumbered.
