Dehalan Industrial Zone, a newly established industrial district with little history, lay east of Hades Hive. To conveniently and rapidly discharge all the district's wastewater, it had been built very close to the hive's steel walls. With a reasonably fast aircraft, one could fly from the walls to the center of Dehalan Industrial Zone—a massive tank factory—in just half an hour.
Pipelines extending from there ran directly into the city walls, with all wastewater discharge controlled by periodically opening automatic gates. Though those thick pipes were filled with deadly radiation and chemicals, anyone who could endure the pollution capable of melting flesh could "safely" attack the heart of Dehalan Industrial Zone through them.
The Ork tide swiftly surrounded the entirety of Hades Hive and began assaulting the city from every direction. The charges and battles against Planetary Defense Force positions that the Orks had anticipated never came. The mines buried in the ground made their assault on Hades Hive incredibly boring.
After watching their comrades get blown to pieces by anti-personnel mines, some Orks abandoned the Waaagh! and headed deep into the subcontinent to fight the Planetary Defense Force troops defending themselves along rivers and mountains.

The Orks wandered through Hades Hive's streets, the enormous hive structure perfectly dispersing the mass of their army. Those junk armored vehicles that had been like a flood
