The sky was wrong.
That was the first thing John Smith noticed.
It wasn't the familiar gray of city pollution or the orange glow of sunset reflecting off glass towers. It was crimson—thick and swirling like liquid fire poured across the heavens.
The second thing he noticed was the smell.
Smoke. Blood. Burning wood.
And the third—
He was no longer in his apartment.
John stood in the middle of a shattered cobblestone street. Around him, medieval buildings leaned at impossible angles, roofs collapsed, market stalls overturned. Bodies in steel armor lay scattered between broken carts and shattered shields.
A distant roar echoed across the ruined city.
Deep. Inhuman.
John exhaled slowly.
"Okay," he muttered. "That's new."
He checked his hands. Solid. Real. No controller. No keyboard.
Another roar—closer.
At the end of the street, something stepped through the smoke.
It was massive—over three meters tall, skin red and cracked like molten rock. Curved horns jutted from its skull. Its claws scraped sparks from stone as it walked.
Behind it, smaller creatures crawled over walls and rooftops, eyes glowing with predatory hunger.
Demons.
John's heartbeat accelerated—but his thoughts sharpened.
Panic later.
Assess now.
A metallic chime echoed inside his mind.
> SYSTEM INITIALIZING…
MILITARY COMMAND PROTOCOL DETECTED
ZERO HOUR INTERFACE LOADING
A translucent tactical HUD exploded into existence before his eyes.
Grid lines overlaid the city. Enemy silhouettes highlighted in red. Terrain elevation rendered in crisp detail.
And at the center of the interface—
Three rotating emblems.
USA
China
GLA
Below them blinked a single command:
> SELECT YOUR FACTION
John stared.
This wasn't just any military system.
It was based on Command & Conquer: Generals – Zero Hour.
But the readouts scrolling beside it were different.
Unlimited Supplies: ACTIVE
No Cooldowns: ENABLED
All Units Available Upon Infrastructure Completion
Realistic Combat Physics: ENGAGED
The demon at the end of the street roared and began to charge.
John didn't hesitate.
He tapped USA.
The emblem flared brilliant blue.
> USA FACTION SELECTED
COMMAND CENTER DEPLOYMENT READY
The ground trembled violently.
Behind him, a massive steel crate materialized out of thin air, slamming into the cobblestones and crushing debris beneath it. Panels unfolded outward with mechanical precision. Hydraulic arms extended. Walls locked into place.
Within seconds, a fully operational USA Command Center stood in the middle of a medieval ruin.
The demon slowed, confused.
John turned calmly.
"Let's see if this works."

Base Construction
"Deploy Power Plant."
Another crate dropped from nowhere, unfolding into a humming reactor. Blue energy surged through cables connecting to the Command Center.
"Supply Center."
"Barracks."
Each structure assembled in moments, steel and concrete rising like a technological invasion.
The demon roared again and lunged forward.
"Barracks complete."
The doors slid open.
Four Rangers sprinted out, rifles raised.
"Target hostile. Engage."
Gunfire shattered the eerie silence.
The sound was deafening against stone walls.
Bullets tore into the demon's chest. Black blood sprayed across cobblestones. It staggered—but kept moving.
Smaller creatures shrieked and rushed from alleyways.
"War Factory."
The structure unfolded behind him.
Seconds later, a Humvee rolled out, its mounted machine gun swiveling automatically.
It opened fire.
The street transformed into a kill zone.
Demons fell under concentrated gunfire. The large brute roared in rage, swinging a claw that slammed into a Ranger's shield—
Before a volley of focused shots ripped through its skull.
It collapsed with a thunderous crash.
Silence followed.
Smoke drifted across steel and stone.
John's HUD updated.
Enemy Wave Neutralized.
Perimeter Secure.
Resources: ∞
He stared at that last line for a moment.
"Unlimited," he whispered.
Supply trucks were already rolling out, collecting glowing crystalline ore scattered among the ruins. The system had identified it automatically as usable resource material.
Magic or oil.
Didn't matter.
It was fuel.

First Survivors
A faint sound reached him.
Coughing.
Human.
John gestured to two Rangers.
"Cover me."
He moved toward a partially collapsed chapel.
Inside, beneath fallen beams, a small group huddled—knights in silver armor, visibly wounded.
And in their center—
A young woman in torn royal attire.
Her long auburn hair was streaked with ash, but her posture remained dignified despite the chaos.
She stared at him—at the soldiers behind him—at the weapons she had never seen before.
One knight raised his sword weakly.
"State… your allegiance."
John stopped a few meters away.
"Currently?" he said evenly. "Anti-demon."
The princess studied him carefully.
"You are not of this kingdom."
"No."
Another distant roar echoed from somewhere beyond the city.
Bigger.
Stronger.
John's HUD flickered as long-range sensors detected massive movement near the northern gate.
Threat Level: HIGH.
He looked back at the survivors.
"You're not safe here," he said calmly.
The princess lifted her chin.
"This is my capital."
John met her gaze.
"Then let's make sure it stays yours."
Behind him, more structures were already rising. Tanks assembling. Missile teams forming.
The medieval square was transforming into a modern military stronghold.
Above the burning skyline, two fighter jets screamed into existence, cutting through crimson clouds.
John watched the tactical map expand beyond the city walls.
Red markers.
Hundreds of them.
He felt no fear.
Only focus.
Zero Hour had begun.
And this world was about to learn what overwhelming firepower meant.
