Shadow War - Armagedon

The imperial hive world of Armageddon is engulfed in planetwide war. As countless hordes of ferocious Ork warriors surge across the jungles, mountains and ash wastes, they are met in fierce combat by the amassed soldiers of the Astra Militarum and the mighty Space Marines of the Adeptus Astartes. The bloddiest and most gruelling conflicts are fought within the hives: the ancient, towering cities that are the last strongholds of humanity. 
In and around Hive Archeron, a site of endless battle, elite squads of soldiers are deployed on search and destroy missions. These guerilla fighters operate where larger armies are unable, creeping through the siege lines into the twisting pipes and gantries that snake throughout the hive. They are assassins and saboteurs, scavengers and predators, they are the kill teams of Armageddon.
