The first wave of engagement concluded in mere minutes.
The Ork elite guards, who had once stalked naval ratings and mortal crewmen through the ship's iron belly, dismissing hard-slug stubbers and las-fire with impunity behind their heavy armor, now found their roles utterly reversed.
The close-quarters slaughter enacted by the Iron Men was defined by a calculated, extreme brutality.
Shimmering, mono-molecular edges cleaved through the air multiple times a second. The greenskins would barely close the distance before the automatons' four kinetic limbs sliced them into a disheveled heap of severed flesh and bone.
Gouts of viscous xenos blood sprayed continuously across the alloy carapaces of the mechanical units, pooling and flowing along the armored plating like streams of crimson meltwater before dripping onto the deck-plates.
This display of unmitigated mechanical violence was soon witnessed by the Imperial survivors huddling in the dark, gothic recesses of the sub-decks.
Several mortals, unable to stomach the sheer geometric precision of the butchery, retched violently into the shadows.
Yet, the advancing cybernetic forces remained entirely indifferent to human shock; their primary programming dictated a swift purge. The faster the greenskins within the warship were eradicated, the lower the statistical probability of collateral mortal casualties.
As the tireless mechanical columns ground deeper into the vessel, the Orks quickly realized the lethality of these multi-legged iron monoliths.
Zog Steeltoof abandoned all care for preserving the integrity of the capital ship. He roared at his Boyz to bring out their loudest, most destructive "shootas" and "boomas."
Though he possessed a primal fondness for Imperial battleships, viewing them as massive, heavily gunned testaments to the glory of the Waaagh!, he was a cunning warlord.
If he remained stubborn about keeping the vessel intact, his Boyz would be wiped out to the last brute before they ever reached the bridge.
Spurred by Steeltoof's direct commands, the Orks adapted. Emulating the defensive doctrines of the Imperial forces they had so often slaughtered, they erected makeshift barricades at key transit intersections and began unlimbering heavy, volatile weaponry.
Melta-burnas, zzap gunz, and massive, custom-built ordnance pieces that blurred the line between heavy stubbers and artillery pieces were shoved over the scrap-barriers.
The thick, uneven barrels and crudely bolted assemblies epitomized the ramshackle, terrifying power of Ork technology, synonymous with extreme destructive yield and catastrophic unreliability.
No sooner had the greenskins stabilized their firing positions than the Erratana-class Armored Wardens, spearheading the vanguard, rounded the corridors.
Leveraging their immense muscular bulk and cybernetic augmentations, the massive Orks hefted heavy melta-weapons, ordinarily locked to fixed ground mounts, directly in their meat-hook hands.
They unleashed a concentrated, overlapping fusillade directly into the approaching front ranks of the giant machines.
BOOM! BOOM! BOOM!
Regardless of the caliber or nature of their armaments, the Orks' accuracy was utterly abysmal.
Aiming for the chassis but hitting the deck, or targeting the sensory clusters only to scorch an auxiliary limb, was the standard deviation of their fire.
Yet, through sheer volume, the most unfortunate Armored Warden at the point of the wedge was instantly engulfed by over a dozen overlapping beams of searing orange heat and blinding, turquoise plasma the moment it crossed the threshold into the intersection.
The first three thermal impacts shattered its heavy, integrated kinetic shielding with a deafening crack. The subsequent torrent of superheated energy struck the bare alloy hull, melting nearly two-thirds of the machine's central frame into sloshing slag.
The ambient thermal backwash was so intense that even the armored bulkheads of the Imperial battleship buckled and liquefied into glowing puddles.
"WE IS DA STRONGEST! YOU'Z DEAD NOW, TIN CAN!"
"KRUSH DA GIT-MACHINES! KILL 'EM ALL!"
"LOOT! LOOT! DAT SHINY CHOPPA IS MINE!"
Stimulated by the successful kill, the greenskins erupted into a discordant chorus of roars and deafening, guttural shouts of Waaagh!, their voices echoing through the vaulted corridors.
Detecting the shift in the xenos' tactical disposition, the remaining Armored Wardens instantly reconfigured their weapon matrices.
The pale-gold particle-vibration blades retracted into their housings, replaced by high-energy plasma arrays crackling with blinding arc-lightning and horrific, pale-green phosphor weaponry.
Relying on target-acquisition subroutines that operated at speeds the xenos biology could not perceive, the multi-ton automatons began climbing the vertical surfaces of the corridor.
The heavy, metal talons of their multi-legged chassis bit deep into the thick, gothic iron walls. Assisted by localized electromagnetic locks, these massive war-engines scuttled across the vertical bulkheads, with several units inverting entirely to sprint upside down across the ceiling.
To the cold logic of the Iron Men, structural damage to the ship was irrelevant.
Once the compliance purge was complete, Sapient Machine Automatons, serving as the servitor-equivalent, would simply 'repaint' the corridor walls with swarms of nanite construction matrices.
The sight of massive, mechanical arachnids sprinting across the walls threw the Orks' primitive tracking capabilities into total disarray, causing their already terrible accuracy to degrade completely.
Conversely, firing posture meant nothing to the cold calculus of the machine.
Whether static, pivoting, or sprinting at hyper-velocity upside down, their targeting solutions remained absolute.
An Armored Warden inverted on the ceiling fired a precise stream of white-hot phosphor directly through the narrow viewing slit of an Ork scrap-shield. The residual thermal energy bypassed the metal plating entirely, instantly vaporizing the brute's skull from the inside out.
Seeing this, some of the more cunning greenskins desperately grabbed jagged sheets of reflective metal, attempting to use them as primitive mirrors to track the automatons from behind cover.
They soon realized the futility of the gesture.
The thick, improvised alloy barricades were systematically punched through by superheated plasma bolts, leaving behind a series of smoking, melted cavities.
In sectors where structural geometry restricted direct line of sight, the Armored Wardens simply bypassed the choke points entirely by wall-running over the Orks' heads, dropping directly into the center of their defensive nests.
Before the howling greenskins could swing their heavy, crude firearms, the Armored Wardens spun their upper torsos in a continuous, 360-degree arc, their four particle-vibration blades transforming them into whirling cyclones of mono-molecular death.
Within a single, fluid second, the interior of the bunker was transformed into a horrific slurry of minced xenos flesh, shattered scraps of iron armor, and detonated weapon components.
The slaughter was so absolute that it triggered latent genetic memories within the surviving Orks, evoking the primal nightmares of land battles against the Tyranid swarms.
The lightning-fast drop-assaults mirrored the predatory ambushes of Hive Fleet Lictors, slicing through everything with terrifying ease.
Yet, these mechanical anomalies were far more resilient than any bio-engineered beast.
The Armored Wardens advanced in tight, disciplined cohorts, appearing by the dozens at every intersection like armored Tyranid Warriors.
What truly unnerved the greenskins was the machines' overlapping force fields, their overwhelming kinetic strength, and an uncanny, unliving agility that defied their immense weight.
The mechanical tide ground over the Orks' desperate fortifications without slowing down, its metal limbs trampling the scrap-barricades into flat sheets of iron as it pressed onward.
After sustaining nearly fifty-percent casualties, the remaining greenskins were forced to fall back, abandoning the mid-decks and retreating toward the heavily fortified perimeters of the primary bridge.
In exchange, one hundred and thirty-six Armored Wardens had been rendered combat-ineffective.
The vast majority of these losses had occurred during the initial, concentrated melta-ambush, where the sheer volume of thermal ordnance had overridden their shields and reduced their chassis to molten slag.
As for the units that had only sustained superficial structural damage, they remained entirely operational.
Internal nanite mother-machines immediately swarmed over the scarred plating, sewing the disrupted alloy matrix back together in real-time.
A fully mobilized, non-compromised cohort of Iron Men was an unstoppable force; until their raw energy reserves were entirely depleted, little short of total molecular vaporization could halt their advance.
Even the destroyed units were far from a permanent loss. Once the automatons began the post-battle reconstruction of the starship's corridors, the slagged remains of the fallen machines would be collected, recycled, and fed directly into the Sapient Factories to be forged anew.
Sitting within the command center of the bridge, Zog Steeltoof listened to the frantic, guttural reports of his retreating Boyz. The developing situation was giving his massive, scar-tissue-covered head a distinct ache.
Since he had joined the grand migrations of Ghazghkull Thraka to ravage the domains of the mortal Emperor, he had fought against every manner of foe the galaxy had to offer.
He had broken the specialized Legio Cybernetica phalanxes of the Adeptus Mechanicus across a dozen forge worlds.
Yet, it was blindingly obvious that the unyielding, silent entities currently carving through his retinue bore no resemblance to the lumbering, binary-shackled constructs of the Martian Priesthood.
For a brief moment, the giant Warlord felt a rare twinge of uncertainty.
However, hesitating before a good fight was entirely anthema to the soul of an Ork.
Steeltoof hoisted his massive, crackling power klaw and decided he would see these unique "tin cans" for himself.
Flanked by a roaring mob of his largest, heaviest Nobz, Steeltoof soon arrived at a secondary junction where a desperate firefight was unfolding.
Suddenly, an Armored Warden detached itself from the shadows of the vertical bulkhead, leaping directly into the center of the Ork column with its blades bared.
Steeltoof's reflexes were monstrously fast for his size. His massive, heavy power klaw snapped outward mid-air, catching the automaton squarely around its central chassis.
With a malicious grin, the Warlord squeezed. The field disrupting energy of the weapon flared violently, snapping the Armored Warden cleanly into two fractured halves.
Yet, even as its lower multi-legged frame collapsed to the deck-plates, the machine's upper torso refused to cease function. Its four independent limbs continued to lash out, the particle-vibration blades striking repeatedly against the heavy armor of Steeltoof's power klaw in a desperate bid to sever the mechanism.
Steeltoof's eyes narrowed into tiny, dangerous slits of low-born cunning and feral ferocity.
Raising the massive power klaw high, he swung it in a brutal, sweeping arc, swatting the thrashing mechanical torso across the corridor. Before the machine could hit the deck, Steeltoof followed through with a thunderous, metal-shod fist, hammering the remaining chassis directly into the reinforced iron wall of the ship.
The sheer, kinetic violence of the impact was so immense that the internal quantum energy core of the Warden was completely ruptured, flickering out into silent darkness.
Seeing their massive Warlord crush the unstoppable machine with his bare hands, the surrounding Ork Boyz erupted into a fanatical, deafening cheer. Their flagging morale was instantly restored, replaced once more by a burning, psychotic lust for war.
