After centuries of peace, the Imperium is thrown into panic as human worlds everywhere are menaced by orks. In a relentless tide of slaughter, ork attack moons destroy planet after planet with gravity weapons of unstoppable power. On Terra, the High Lords are paralysed by the scale of the threat and fail to take any effective action. With entire Space Marine Chapters missing or known to have been wiped out, does anyone have the will and the power to rise to the Imperium's defence?

As ork ships lay waste to world after world, heading inexorably towards Terra, Imperial citizens despair. The High Lords become desperate to prove that victory is possible, no matter the cost. A massive navy fleet is assembled - their mission to make a definitive strike against the orks at Port Sanctus, an area of enemy-held space. But when the Imperial armada arrives, they find themselves outclassed and outmanoeuvred. Can human courage and faith possibly prevail against such terrible odds?

Despite the Imperium's best attempts to forestall the ork plague that is wreaking havoc in human space, an ork attack moon now hangs over Terra. As its malevolent presence gazes down at the Imperial Palace, terrified citizens run riot in the streets. In a last-ditch attempt to destroy the attack moon, a proletarian crusade is launched. Thousands of ships large and small head to the moon carrying billions of citizens, all eager to take the fight to the enemy.

The Imperium's situation has never been more grim - an ork attack moon hangs over Terra, and ork armadas ravage human space. To make matters even worse, eldar strike at the heart of the Imperial Palace, forcing humanity's defenders to fight on two fronts at once. Though it seems nothing can stop the orks - neither brute force, science, nor faith - an unlikely alliance in the furthest reaches of space uncovers the first clue how to defeat the greenskins. The Adeptus Astartes now face an almost impossible task....

Paralysed by the continued ork invasion of Imperial space, the rulers of Terra continue to fight among themselves. Finally losing patience with the High Council, Koorland - the last surviving Imperial Fist - ousts the Lord Commander and seizes control. Elsewhere, the Fists Exemplar are forced by circumstance to fight alongside the Iron Warriors. Where will such an alliance lead - can a Traitor Legion ever be trusted?

The Imperium has been brought to the edge of extinction by an ork invasion of unprecedented scale and depth. Piecemeal strikes against the invaders prove ineffective - for every ork fleet destroyed, five more appear. The only solution is to find and kill the orks' warlord - the Great Beast. Surely if its leader is killed, the greenskins' empire will fall apart in agony of infighting and confusion.

The attempt to hunt down and kill the orks' leader has ended in catastrophe. The Imperium is reeling from the loss of so many beloved heroes, and the military forces of mankind have been reduced to tatters. Koorland now knows that brute force is not the answer - but how else can the orks be fought? In a radical move, he creates small, mixed Chapter units of Adeptus Astartes - compact teams that will hit the enemy hard and fast and with deadly accuracy.

As the ork menace ravages the galaxy, the Imperium faces its darkest hour. Its fleets are in ruins, its armies devastated - amongst them the noble Imperial Fists - and even a primarch of myth has fallen against the Beast. As brute force fails, Koorland resorts to increasingly desperate tactics against the greenskins. A final hope lies in deploying the controversial Deathwatch and the Sisters of Silence in a deft strike at the heart of the ork empire.

Ufthak Blackhawk and the green tide descend upon Hephaesto - an Adeptus Mechanicus forge world bristling with loot - only to find it already under siege by the notorious Freebooter Kaptin Badrukk. When his warboss, Da Biggest Big Mek, orders temporary co-operation, Ufthak seeks to make a name for himself by crushing some of the Imperium’s most advanced defenders and claiming the greatest prize. 

The Imperium's attempts to defeat the ork menace seem doomed to failure; it is only a matter of time before the greenskins triumph, and mankind is wiped from the galaxy. Yet there is some cause for hope - the psychic weakness of the orks has been found, and a few Sisters of Silence survive. Supported by the full might and technology of the Adeptus Mechanicus, the Space Marines head to the orks' home world one final time. This time there will be no retreat, no surrender. They must succeed...or die in the attempt.

Across the length and breadth of the galaxy, humankind celebrates its salvation and relishes the prospect of a return to peace. But the war against the orks has driven the political bedrock of the Imperium, exposing its rotten core. One man, one powerful man, decides he has the solution and launches a campaign of destruction so terrible that thousands of years later his actions will still be viewed with horror.

Die Custodeswache wacht seit Anbeginn des Imperiums über den Palast des Imperators auf Terra. Es ist ihre Aufgabe, den Herrn der Menschheit vor allen inneren und äußeren Gefahren zu beschützen. Ihre furchteinflößende Entschlossenheit ist in der gesamten Galaxis berüchtigt und ihre goldene Rüstung ist das Letzte, was ein Attentäter oder Saboteur jemals sieht. Zusammen mit den Schwestern der Stille, dem Fluch aller Psioniker und Hexer, haben sie bisher jede Gefahr für den Goldenen Thron gebannt... bis jetzt.

The Death Korps of Krieg are deployed to a soul-crushing siege in the Octarius War Zone. They’re the right regiment for the job, though victory might come at a price that some might balk to pay.

The Night Lords were once among the most potent forces of the Imperium, Space Marines who used fear itself as their weapon. Now, cast adrift from the Emperor's light and hunted as heretics after their monstrous betrayal, the Night Lords clad themselves in symbols of death and fight the Long War, bringing pain and terror to all who worship the corpse-god of Terra. A summons from Warmaster Abaddon sends these rebels on a dangerous journey that leads inexorably to a conflict with the Emperor's chosen warriors, the Blood Angels.  

When Horus fell, his Sons fell with him. A broken Legion, beset by rivalries and hunted by their erstwhile allies, the former Luna Wolves have scattered across the tortured realm of the Eye of Terror. And of Abaddon, greatest of the Warmaster's followers, nothing has been heard for many years. Until now....
