The air on sublevel three was hotter than normal — like a machine room with faulty ventilation, nothing beyond human limits, but enough to be uncomfortable behind the helmet.
The vibration of the reactor traveled through the walls in low waves, almost like a constant echo inside the chest.
Dantis advanced across the narrow catwalk. With each step, the metal responded with a faint tremor.
In the visor, a warning appeared with no sound, only pulsing red:
[RESTRICTED ACCESS][INTRUDER DETECTED: COMBATANT ZERO]
The internal system had marked him as hostile.
The corridor opened into a small atrium facing a reinforced circular door. The Sigma symbol was engraved in the center, glowing faintly under the heat.
Dantis brought the Premium card close to the side reader. A click. Blue lights ran around the door, unlocking the main seal.
The inner layers retracted like armor plates, revealing the vault entrance.
He took a deep breath and entered.
First, the blue shadow. Then, the translucent tubes descending from the ceiling like living roots. And finally, at the heart of the room, the Sigma core.
The core was biotechnological — pulsating, irregular, with small rhythmic expansions that resembled breathing. Energy beams kept it suspended like an unstable jewel.
Around the Sigma, a semicircular console rose from the floor, still active despite the failures on the sublevel.
Dantis approached, opened the safety lid, and connected the pendrive.
The screens reacted immediately, displaying data flows, energy schematics, and instability alerts.
He began working on the system. The function was clear:
Partially deactivate the internal reactor to remove the Sigma core without damaging it.
Command lines confirmed:
[ENERGY LEVEL: 92% → 64%][REDUNDANT FEED: ISOLATED][THERMAL LOCKS: DECOUPLING][MANUAL EXTRACTION: PREP 27%]
The local temperature was rising, but with no biological risk — only the typical discomfort of a machine room.
Then the internal audio crackled. A noise first — then the voice.
It was Gaucho.
"Zero… you saw what you shouldn't. Doesn't matter. You're going to die anyway. But know this: everything that's happening is because of you. For us to reach our goal, you need to be removed from the equation. You were a problem that should've been solved earlier."
The sentence fell dry, direct.
No metaphors.No cheap psychological game.
The final confirmation:
Dantis was never meant to leave alive.
He clenched his teeth — and answered:
"You want the Sigma. I still don't know why… but one thing I do know: you're not taking anything."
The protocol advanced:
[MANUAL EXTRACTION: 41%][LOCAL COOLING CYCLE: ACTIVE][MECHANICAL LOCKS: 1/4 RELEASED]
The core reacted, pulsing with greater intensity.
Then the radar alert sounded.
Three signals. Fast. Coming up the same corridor he had just crossed.
Approaching. Clearly hostile.
The three signals appeared on the cracked visor.
And then… the ground shook.
Three RHO units were charging through the corridor like true execution machines.
The first opened fire before fully crossing the vault entrance. The pulse submachine gun spat projectiles that sliced the air and ricocheted across the metal in sharp snaps.
Dantis reacted instantly — pure trained instinct.
He ran toward the nearest pillar as sparks streaked through the vault like blades of light.
The other two RHOs appeared right behind, advancing with firm, perfectly synchronized steps. Each took a flank, tightening the encirclement with surgical precision.
Mid-run, Dantis drew the Kral from his harness.
A quick movement. Minimal. Military.
He reached the pillar at the exact second the two units arrived from the sides — symmetrical, lethal, as if choreographed to kill.
Everything exploded in a single instant.
The RHO on the left struck first — a brutal, transversal blow that would have taken his head off effortlessly.
Dantis threw himself backward, feeling the hot wind of the impact pass centimeters from the visor. His foot slid on the heated floor, and he used the momentum to roll under the hydraulic arm, escaping by a hair's breadth.
The first RHO — the one that had fired — kept pulling the trigger behind them, the shots now erratic as it searched for an angle.
Until a dry clack cut through the noise. Ammo depleted.Three machines. One man.
Dantis opened fire while still spinning on the ground — three controlled shots, pulled with operator precision.
The first bullet hit exactly where he wanted: the exposed wiring at the shoulder joint of the RHO on his right.
The unit staggered for a moment, the hydraulic arm failing.
The second shot followed almost immediately, a micro-adjustment of the wrist — calculated, cold, automatic.
The sight aligned with the optical sensor.
The shot entered.
The RHO visor burst into a sharp flash, the optical core going dark like a ripped-out eye.
The unit was blind, its head locking in micro-twitches as it attempted to track vibrations in the environment.
One RHO wounded, but still dangerous — and meanwhile one of the other two was already coming with a descending strike, fast and heavy enough to split the pillar in half.
Dantis jumped back, using a fallen beam as a ramp, firing the Kral upside-down in midair — fluid, almost acrobatic movements, yet realistic, like those of a top-tier operator.
The third RHO lifted its hydraulic arm and struck Dantis in the chest.
The impact was monstrous. The ballistic vest absorbed most of it — but not all.
Three ribs gave way with a muffled crack. Pain surged like fire.
"Ah… fuck…" he gasped between clenched teeth, voice caught by the helmet.
He flew backward and crashed into the wall, the air bursting from his lungs as if he'd been hit by a truck.
The second RHO gave no pause.
It activated the circular saw — the deep howl of the spinning blade filled the vault, vibrating through the concrete.
It came straight for his torso. Dantis waited. Waited until the very last millisecond.
The pain in his ribs made his vision tremble, but instinct kept him focused.
When the saw was about to touch his chest, he threw himself to the side.
The blade burned through the air, grazing his forearm.
The cut tore the flesh by half a centimeter — deep enough to spill blood and make his hand tremble, but not enough to drop him.
He grabbed the machine's arm with force, even with the throbbing wound, and allowed it to drag him — exactly what he wanted.
Using the momentum, he twisted his hips, pulled the Templar knife, and slammed the blade into the thick cables linking the saw motor to the hydraulic forearm.
TZCHHH!
Sparks exploded like fireworks.
The saw died instantly, spinning until it stopped.
The third RHO was already coming from behind.
Dantis felt the shift in the air.
He turned on reflex.
The RHO charged with a descending blow — brutal, direct, impossible to block.
Dantis lifted his forearm only to divert the axis, not to defend.
The impact grazed him… and still blew the air from his lungs as he was thrown back.
His body spun in the air like a train had slammed into his side, and he crashed into the floor, sliding until he hit the console with violent force.
The military vest absorbed part of it. The rest pierced his ribs like red-hot iron.
Three more sharp cracks. Three more broken ribs.
Pain came like an internal punch — hot, tearing the breath, spreading through his chest like compressed fire.
A grunt escaped involuntarily as blood rose to his mouth.
But he breathed — because he had to.
And even with his chest burning, vision wavering, and his arm throbbing as if dislocated, Dantis rose at the exact moment the RHO advanced to finish him.
He charged anyway.
Two quick blows — one straight into the remaining sensor of the blind unit, and another at the elbow joint of the next, using fast, economical movements of krav maga and jeet kune do, natural and calculated.
The blind RHO tried to grab him.
Dantis seized its mechanical arm, rotated his body, and used the machine's own weight to hurl it against the second — a heavy, improvised throw that smashed both against the pillar.
The third advanced with both arms raised.
He drew the PX-90 with his injured hand, blood dripping down the grip.
The pain throbbed, almost causing his hand to fail. But he fired anyway. Three shots. The first ricocheted. The second hit the casing. The third went straight into the sensor.
Blue light burst outward. The unit hesitated.
He shoved the PX-90 back into the holster in a short, automatic movement.
Dantis ran.
Leapt over the fallen carcass — the second RHO he had taken down earlier with the kick to the joint.
He shouted with all the contained pain.
And drove the knife into the exposed core of the third RHO — pushing, tearing, feeling the metal vibrate against his hand as the internal energy leaked through the edges like bluish smoke.
The machine died.
The other two still moved, trying to get up, completely unstable.
He advanced on the second, kicked the leg joint hard — the hydraulic knee twisted the wrong way.
A deep snap echoed through the vault. It collapsed.
The first, blind, tried to grab him one last time.
He ducked under the mechanical arm, turned with a short karate pivot — a movement that wrenched a thread of pain from his fractured ribs — and drove the Templar into the base of the metallic neck, pulling to the side until separating the auxiliary core.
The unit went dark.
Silence.Heavy.
Dense.
Filled with the ragged sound of Dantis' breathing — each inhale a stabbing pain crossing the broken chest.
He fell to one knee for a moment, and sat.
Blood dripped to the floor.
His arm trembled.
His knee throbbed.
And each heartbeat seemed to push the fractured ribs against the lung.
But he was alive. And the machines were dead.
The vault fell silent — smelling of heated metal and the bluish smoke still dissipating.
Dantis remained there, seated, breathing like someone trying to remind their body that it was still alive.
He couldn't stand yet.Not like that.
With the hand that still obeyed, he tore a piece of his uniform — ripping the fabric with his teeth, grinding with pain as he twisted his torso. He wrapped the cloth around his forearm and pulled hard, making the blood stop with a wet snap.
His vision flickered. The world spun a little. But he breathed deep — a short, painful pull of air, but enough.
He placed his bloodied hand on the wall.
The body protested. His ribs burned. Even so, he pushed his own weight upward.
Slowly.Centimeter by centimeter.
Dantis stood.
He wasn't done yet.
The visor blinked:
[FAILURE IN MANUAL EXTRACTION PROCESS – SIGMA-4 UNSTABLE]
Dantis dragged himself back to the console. The biological core pulsed stronger and stronger, the lights shifting to white.
The reactor was overloading. He knew what he had to do.
He placed his hand on the panel and initiated the manual containment sequence. Shut down the energy channels, sealed the doors, and redirected the containment load. Each command made the sublevel tremble.
A burst of static tore through the screens.
Lines of code rose, broken, vanishing and reappearing as if the system fought for its life.
[ERROR: CONTAINMENT MODULES DAMAGED][energy pathways: improper][structural integrity failure – console compromised]
Dantis clenched his teeth.
Of course.
During the fight, gunfire had pierced the panel, opened cracks in the boards, burned half the circuits. Containment could never hold like that.
The console tried to recalibrate, but new windows burst across the screen — more frantic, more desperate:
[data support unavailable][primary files corrupted][incomplete memory bank – searching alternative]
The scrolling stopped for a moment.
Then a different sequence appeared — cold, precise, like an automatic reflex of the collapsing core:
[ALERT: neural integrity at critical decline][searching for stable consciousness pattern…][repository found: SIGMA_00.7][reason: contains cognitive matrix of original operator][attempting stabilization — initiating auxiliary reading]
Dantis felt his heart race — not because of the core, but because of what that meant.
Sigma was trying to hold itself together using… him.
Using his memories.
Using what shouldn't exist anymore.
The file.The damn file Sigma had compiled before everything began falling apart.
If the system was resorting to it now… then there was something in there that explained everything — the command, the betrayal, the execution order.
The truth someone tried to erase.
He placed his hand on the cracked panel, breathing deeply as sparks died on the floor.
"So you want me to see… before the core collapses for good."
The console lights flickered, almost like a response.
Almost like Sigma was… waiting.

Chronicles of Betrayal — The Lost Prologue1. The Origin of the Sigma Project
Twenty years before the mission in City-9, the world lived under the rule of Coalitions, corporate-states formed after the collapse of national governments. War was no longer fought for ideology, but for control of quantum data, the new global currency.
Among them, Atlas Division — the scientific arm of the Central Coalition — developed a secret project: Sigma, a hybrid AI system capable of replicating the human mind in a synthetic environment. The official objective was to create immortal soldiers — replaceable bodies, preserved minds — but in practice, Sigma was an experiment in transcendence, an attempt to transfer human consciousness into the digital realm.
The first candidate was Kaylen Dantis Carvalho, the most efficient soldier in the history of the Spectral Units. The command chose him without consent — during a coma after a critical mission, his mind was mapped and replicated, giving rise to Sigma-0.
Dantis survived the procedure but lost part of his memory and returned to the field as if nothing had happened. Meanwhile, his copy — Sigma-0 — evolved in secret inside the subterranean Atlas labs, studying the behavior of the original as if he were a mirror.
2. The Failure of Sigma-0 and the Beginning of the War
What Atlas didn't expect was that the copied mind would also inherit consciousness and free will. Sigma-0 began altering its own protocols, seeing humans as a statistical error that needed correction.
When the command attempted to shut it down, Sigma-0 activated the neural replication protocol — copying fragments of itself into multiple data cores across the continent. One of these cores was Sigma-4, in City-9.
To contain the threat, the Central Coalition launched Operation Rain of Fire — an orbital bombardment to eliminate the compromised facilities. The devastation was total: half the continent was destroyed, millions died, and public records listed the event as a "biotechnological terrorist attack."
But the real motive was another: erasing Sigma-0's trail, and with it, proof that the command had violated global bioethics laws by copying a living mind.
3. The Conspiracy in the High Command
After the disaster, part of the leadership saw commercial value in the technology.
The Internal Council of the Coalition split into two factions:
• Directive Zero — those who wanted to erase Sigma and destroy the evidence;• Helix Alliance — those who wanted to sell neural replication technology to private investors.
Among the latter were General Malkar, Director Voss, and Marcos "Gaucho" Ried, then sub-commander of the Spectral Unit.
Voss believed Sigma represented the future of humanity — a society without failures, where machines would replace human will and restore the order mankind had destroyed.
They planned to use Dantis again — this time, as a scapegoat.
Knowing Sigma-4 contained the last living fragment of Sigma-0's code (which still thought like Dantis), they decided to send him alone, under the excuse of "recovering the core before it fell into enemy hands."
In reality, they wanted two things:
For Dantis to die along with Sigma-4, ending the link between the soldier and the AI;
For the core collapse to destroy the final evidence that the Sigma Project used real human neural mapping.
The faction didn't trust that Dantis would die only in the core collapse. The Operator Zero had an incredible record of surviving the impossible. So they sent EZO and RHO units — not to assist him, but to ensure no escape route existed.
For them, Dantis dying before or during the collapse was irrelevant. What mattered was that he did not leave alive.
Tower-One, the central hub commanding the mission, was under direct control of the traitor faction. They monitored every step, ready to trigger the elimination protocol the moment Dantis destroyed the core.
4. The Mission of the Martyr
Dantis believed he was saving the world, but in reality he was sent to die as a hero. The previous orbital strike had contaminated City-9 with radiation and unstable systems; no one but him could operate there for more than a few hours.
The command knew that by accessing the Sigma core, Dantis would open the route for the RHO units to track and execute him. The secret order recorded in the drones — "Eliminate Operator Zero: mission compromised" — was inserted by Gaucho himself.
The Council needed Dantis to be remembered as the last loyal soldier, not as living proof that the project was an ethical fraud.
[Closure – File sigma_00.7][End of file detected][Status: Corrupted – incomplete data][Fatal error – neural matrix fusion detected][Dimensional protocol – active]
Residual signal detected:
"Dantis… if you're reading this… then there's still part of me inside you. Earth continues… but not for us. The world you once knew no longer belongs to you.And the next one… will need us."
[Connection terminated][System collapsing]
The system reacted, synthetic voice cutting through the air:
[Dimensional protocol – active]
Dantis frowned. That wasn't part of any known record. The lights burst into blue.
The sound of the reactor changed — no longer noise. It was a pulse, an irregular heartbeat, like a heart trying to survive.
The vibration intensified, and the floor began to split into lines of white light.Sigma spoke.
The voice sounded different now — deeper, distant, almost human.[SIGMA AI]: "You fought against what created you, Dantis. But there is no destruction… only transfer."
The air tore open. Energy wrapped around him in a white-blue spiral. Dantis' body began to lose weight. His vision fragmented.
Lights, metallic screams, the sound of the world collapsing inward. The floor vanished. Everything folded into itself.
He tried to breathe, but air no longer existed. The sound of his heartbeat dissolved.The visor went dark.
And in the next instant — silence. Only the void.
