In theory, a world bombarded by virus bombs would become nothing more than a swamp of rotting organic matter.
After the entire ecosystem decayed into combustible gases, igniting them would create a planetwide firestorm that burned away every virus and every living thing on the planet.
But for psychic creatures as utterly unreasonable as Greenskin Orks, even virus bombs could only temporarily suppress their reproduction.
Moreover, existing records showed that the same virus bomb could not have much effect on Greenskin Orks a second time.
Their miraculous genome would develop a powerful resistance to viral contamination in an extremely short time.
But for humanity, that brief window was already precious enough.
The orbital drop pods deployed by humanity encountered almost no serious resistance.
The Ork Boyz stationed inside the defensive gun emplacements had already turned into puddles of sludge, unable to continue operating their powerful anti-air weapons in retaliation.
The orbital drop pods fell like meteors, smashing into rock strata that had been stripped of most of their organic matter and baked brittle by extreme heat.
If not for their retro-thrusters, those drop pods could have punched straight through the bedrock and crashed into the planet's crust.
The average surface temperature of Skullcrusher was over one hundred and fifty degrees Celsius. It was already a living hell.
When the drop pod doors slammed down onto the ground, the Astartes of Ashen Claws and the Night Lords immediately felt a wave of heat rush at them.
The servos of their power armor operated normally, while the cooling modules kept the temperature inside at the level most suitable for Astartes survival.
The Astartes Sigismund sent to Skullcrusher were all exceptionally skilled at concealment, infiltration, and stealth.
He understood that unless they found the Ork warlord on this planet, no matter how devastating
