The roar rolled through the underground complex like distant thunder.
Dust drifted from the ceiling.
The reinforced walls vibrated.
For the first time since the outbreak began, Unit Zero’s expression changed.
It wasn’t fear.
It was awareness.
Its amber eye slowly turned toward the lower levels of the facility, as though listening to something only it could hear.
Subject Nine grabbed Elias’s sleeve.
“We have to leave.”
Her voice trembled.
“Now.”
Another heavy impact echoed from below.
The steel beneath their feet groaned.
Noah looked toward the sealed blast doors lining the laboratory.
“Whatever’s down there…”
“I don’t want to meet it.”
The overhead speakers crackled once more.
“Containment Protocol Delta initiated.”
Mechanical locks engaged throughout the laboratory.
Emergency shutters descended over observation windows.
The calm voice continued as if reading from a checklist.
“Prototype Unit Zero has exceeded projected combat efficiency.”
“Secondary prototypes are entering active synchronization.”
Elias frowned.
“Synchronization?”
Subject Nine’s face turned pale.
“They’re waking together…”
She looked at Unit Zero.
“They can feel each other.”
The words sent a chill through the room.
These creatures weren’t simply monsters.
They were connected.
Unit Zero took another slow step forward.
It ignored Noah.
Ignored Subject Nine.
Its attention never left Elias.
“Elias.”
Its voice sounded clearer this time.
Less distorted.
Almost…
Curious.
“Why?” it asked.
Elias blinked.
“…What?”
The Chimera tilted its head.
“You…”
It struggled with the next words.
“…alive.”
Fragments.
Broken thoughts.
But they carried meaning.
The creature wasn’t asking who Elias was.
It was asking why he had survived.
Before Elias could answer, the observer interrupted.
“Cognitive development continues beyond expectations.”
“No external stimulus required.”
“Remarkable.”
Unit Zero slowly turned its head toward one of the security cameras.
For a brief second…
It frowned.
Then, without warning, it swung its claw.
A shockwave exploded through the laboratory.
The camera shattered.
Static consumed every monitor in the room.
The speakers fell silent.
No announcements.
No observations.
Nothing.
Noah stared.
“Did…”
“…did it just attack the cameras?”
Subject Nine whispered.
“It hates being watched.”
The laboratory lights flickered.
Emergency power replaced the primary system.
Darkness swallowed half the room.
Only red warning lights remained.
The shadows became deeper.
Longer.
More threatening.
Elias noticed something strange.
Unit Zero wasn’t advancing anymore.
Instead, it stood perfectly still.
Listening.
Watching.
Almost…
Protecting the laboratory entrance leading to the lower floors.
Another roar echoed from below.
Closer this time.
A metallic door somewhere beneath them buckled inward.
Subject Nine shook her head.
“No…”
“They shouldn’t be awake yet.”
A terminal beside one of the containment pods suddenly came to life.
Its screen flickered despite the damaged power grid.
PROJECT CHIMERA
Emergency Data Recovery Available
Estimated Download Time: 90 Seconds
Elias immediately understood.
“We need that data.”
Noah looked between the terminal and Unit Zero.
“You’re kidding.”
“If we leave now, we’ll never know what happened here.”
“And if we stay?”
“We might die.”
Noah sighed.
“You always pick the dangerous option.”
“I’ve noticed.”
Elias rushed toward the terminal.
His fingers flew across the cracked keyboard.
Most files were corrupted.
Entire databases had been erased.
Someone had already tried to wipe Project Chimera from existence.
Then one folder remained accessible.
ARCHIVE: INCIDENT DAY ZERO
Before he could open it—
Subject Nine screamed.
“Elias!”
Unit Zero had moved.
Not toward him.
Toward the terminal.
One massive claw crashed into the workstation.
The monitor exploded into sparks.
Hard drives shattered.
Storage units split apart.
The download stopped at 7%.
Elias cursed under his breath.
The Chimera stared at the destroyed computer.
Its expression remained unreadable.
Then it slowly looked back at Elias.
It hadn’t destroyed the data out of rage.
It had destroyed it intentionally.
As if it understood exactly what the files contained.
The facility trembled violently.
Concrete cracked overhead.
A deafening alarm replaced the mechanical warnings.
REACTOR INSTABILITY DETECTED
FACILITY SELF-DESTRUCT SEQUENCE AVAILABLE
Subject Nine’s breathing became uneven.
“They’ll bury everything.”
“They’ve done it before.”
Elias looked at her.
“You’ve seen this happen?”
She nodded slowly.
“They erase every failure.”
Her eyes drifted toward the shattered containment pods.
“They don’t leave evidence.”
A deep, guttural growl echoed from the corridor outside.
Noah spun around.
Movement.
Not one.
Several.
Dark silhouettes emerged beyond the broken doorway.
Ordinary infected.
Drawn by the alarms.
Their snarls filled the corridor.
Dozens of glowing eyes appeared in the darkness.
The laboratory had become a cage.
Infected behind them.
Unit Zero before them.
Something worse awakening below.
Unit Zero glanced toward the approaching infected.
It released a low growl.
Every infected stopped.
Absolute silence.
Then…
One by one…
They backed away.
Not out of fear.
Out of instinct.
Like wolves yielding to an alpha.
Elias watched in disbelief.
“So that’s it…”
The infected weren’t acting randomly.
Hierarchy existed.
The realization was more terrifying than any roar.
Subject Nine leaned against the wall, struggling to remain conscious.
“They’re changing…”
“The virus isn’t spreading anymore.”
“It’s organizing.”
Elias looked toward Unit Zero again.
The Chimera still hadn’t attacked.
Instead, it simply watched him.
Almost as if waiting for a decision.
Another violent explosion erupted beneath the facility.
The floor split open several meters away.
Hot steam burst upward through the widening crack.
A massive claw—far larger than Unit Zero’s—slammed against the fractured concrete below before disappearing again.
Only a glimpse.
But enough.
Noah’s voice shook.
“Tell me that wasn’t another prototype.”
Subject Nine closed her eyes.
“No…”
“It wasn’t.”
Silence followed.
Then she whispered the words Elias wished he hadn’t heard.
“That one…”
“…was never supposed to wake up.”
A thunderous roar ripped through the underground complex.
This time…
Even Unit Zero took a single step backward.
Elias understood immediately.
Whatever was beneath them…
Even the first successful Chimera considered it dangerous.
He tightened his grip on his weapon.
“Move!”
No one argued.
As the four survivors raced toward the emergency escape corridor, the lights throughout the laboratory died one by one.
Behind them, Unit Zero remained standing in the darkness.
It didn’t pursue.
It simply watched Elias disappear into the shadows.
Then, in a voice too quiet for anyone but itself to hear, it whispered one final word.
“…Brother.”
