LEVEL 0: PATIENT ZERO

Flatline

The last thing Kade Miller heard wasn’t the weeping of a loved one or a profound final word. It was the rhythmic, clinical insult of a heart monitor that had been betting against him for months.

Beep. Beep. Beeeeeeeeee

The sound stretched into a horizon of white noise. For a moment, the agony in his lungs, the sensation of breathing through wet concrete simply evaporated. It was the most productive thing his body had done in nineteen years: it had finally stopped trying.

Then, the world turned red.

Not the red of blood, but the neon, artificial red of a low-battery warning on a faulty monitor. Kade blinked. His eyelids felt like they were made of rusted iron.

[SYSTEM INITIALIZATION: 1%]

[CRITICAL ERROR: BIOLOGICAL SIGNATURE TERMINATED]

[SEARCHING FOR COMPATIBLE HOST... ERROR]

[INCOMPATIBLE DATA DETECTED... OVERRIDE INITIATED]

Kade tried to gasp, but his diaphragm didn’t twitch. Panic, sharp and cold, flared in his mind, yet his chest remained a hollow, silent cavern. He wasn't in his ICU bed anymore. The air smelled of formaldehyde, industrial bleach, and something sweet like rotting peaches.

He was lying on a stainless-steel slab. A thin plastic sheet covered him, clinging to his skin with the static of the dead.

[INTEGRATION COMPLETE]

[WELCOME, PATIENT ZERO]

"I'm... dead?" Kade thought. His internal voice sounded too loud in the vacuum of his mind. He tried to sit up. It wasn't the fluid motion of a living teenager; it was a mechanical, jarring heave. His spine popped with a sound like dry kindling snapping.

The plastic sheet slid off, revealing skin that looked like bruised parchment. His hands, once trembling with the weakness of stage-four lung cancer, were now steady. Too steady. They were stone.

"Okay," Kade croaked. The sound was a jagged vibration in a throat that felt like it had been lined with sandpaper. "New plan. Don't go into the light. The light is apparently a glitched UI."

He swung his legs off the metal table. His feet hit the tiled floor with a heavy, wet thud. There was no sensation of cold. There was no sensation at all, other than a dull, magnetic pull at the base of his skull, a hum that felt like a radio tuned to a dead frequency.

CRASH.

The sound of shattering glass erupted from the hallway. Kade froze. It was followed by a wet, rhythmic slapping noise, the sound of bare feet on a waxed floor, moving with a frantic, uneven gait.

"Nurse?" Kade tried to shout, but it came out as a low, guttural rasp.

[LEVEL 0: PATIENT ZERO]

[ACTIVE BUFF: UNDEAD VIGOR (RANK F)]

[CURRENT OBJECTIVE: ESCAPE THE MORGUE]

"Escape the morgue," Kade muttered, his eyes darting to a flickering fluorescent light above. "Great. I finally get a HUD, and it's for a horror game I didn't buy."

He limped toward the heavy double doors of the refrigeration room. His body felt heavy, his muscles lagging a millisecond behind his brain's commands. As he reached the door, he caught his reflection in the polished chrome of a storage locker.

He looked like a car crash survivor who had waited a week to seek help. His eyes weren't the vibrant hazel they had been an hour ago; they were a cloudy, milky grey, shot through with thin, pulsing veins of violet light.

"Well," he whispered, tilting his head until his neck cracked. "At least the bags under my eyes are gone. Silver linings."

He pushed the doors open.

The hospital basement was a war zone of clinical debris. A gurney lay overturned, its wheels still spinning lazily. But it was the blood that caught his attention. It wasn't just on the floor; it was sprayed across the ceiling in a frantic, abstract pattern.

Standing over a pile of blue surgical scrubs was something that used to be a security guard. Now, it was a mess of protruding bone and greyish muscle. The thing turned, its jaw hanging by a single tendon.

[THREAT DETECTED: MINDLESS DRONE (LVL 1)]

The guard didn't attack. It paused, its nostrils flaring as it took in Kade’s scent. It tilted its head, a low whine vibrating in its throat.

Kade felt that magnetic hum at the back of his brain intensify. For a split second, he didn't see a monster; he felt a connection. A tether. It was like looking at a very stupid, very hungry dog.

Move, Kade thought, the command rippling out of him involuntarily.

The zombie stumbled back, its heels clicking on the tile. It slumped against the wall, its cloudy eyes fixed on Kade with a weird, vacant reverence.

"That's... actually pretty cool," Kade said, his confidence flickering for the first time. "I have minions. I’m a sickly, undead overlord."

But the System wasn't done with him.

[WARNING: SYSTEM SANCTITY BREACHED]

[INTERNAL CLEANUP PROTOCOL INITIATED]

[ELIMINATE THE ANOMALY]

The red light in the hallway didn't come from the emergency lamps. It came from the air itself. Pixels of light drifted down like digital snow, coalescing into a shape at the end of the corridor. It was a floating, geometric orb of white light, trailing long, translucent ribbons of data.

[CLEANER BOT (LEVEL 3)]

[MISSION: PURGE INFECTED BIOMASS]

"Purge?" Kade's eyes widened. "Hey! I'm not biomass, I'm Kade! I have a library card!"

The orb didn't care about his civic status. A lens opened in its center, glowing with a hum of gathering electricity.

Zap.

A bolt of blue energy hissed through the air. Kade dived or rather, he threw his heavy weight to the side. The bolt hit the wall where his head had been, melting the cinder block into glowing slag.

"Okay! Not a friendly robot!" Kade scrambled to his feet, his new "Undead Vigor" kicking in. He didn't feel the burn of lactic acid or the shortness of breath that had defined his life. He just felt... momentum.

He sprinted toward the service stairs, his bare feet slapping the floor. Behind him, the Cleaner Bot hummed, its ribbons of data lashing the air like whips.

Zing.

Another bolt grazed his shoulder. Kade didn't feel pain, but he saw the notification.

[HP: 88/100]

[CAUTION: NECROTIC TISSUE CAUTERIZED]

"Stop hitting me!" Kade ducked into the stairwell, slamming the heavy fire door shut.

He leaned against the door, listening to the thump-thump-thump of the bot hitting the steel. He waited for his heart to race, for his pulse to thrum against his eardrums, for the familiar panic-attack sweat to break.

He waited.

And waited.

He pressed his hand firmly against his chest. Nothing. Just the cold, unmoving cage of his ribs. There was no throb in his neck. No warmth in his veins.

The silence inside his own body was louder than the robot outside.

"Oh god," he whispered, a sob catching in a throat that didn't need air. "It's real. I'm really... I'm really gone."

The weight of it hit him harder than the energy bolt. All those months in the ward, he had joked about death, played it off with dark humor to make his mom cry less. But now, staring at his grey, motionless hands in the dim stairwell light, the joke was over. He was a glitch. An accident.

Thud.

The fire door groaned. A glowing red line began to appear in the center of the steel as the Cleaner Bot started cutting through.

"No," Kade snapped, his grief turning into a sharp, jagged spike of anger. "I spent six months fighting a tumor. I am not getting deleted by a flying light bulb."

He looked up the stairs. The hospital was a labyrinth, and he was at the very bottom. He needed a weapon. He needed a plan. Most of all, he needed to stop being Level 0.

He started to climb, his movements becoming more fluid as his brain figured out the new "controller" for his limbs. He reached the first-floor landing and peered through the small reinforced window.

The lobby was a nightmare. The "Integration" had turned the crowded waiting room into a buffet. People were screaming, running toward the automatic doors, only to find them locked by the same red digital lattice that had appeared in the morgue.

But it wasn't the zombies that were the problem. It was the "Players."

Kade saw a man in a business suit holding a shimmering translucent sword. He was swinging it wildly, decapitating a nurse who was mid-transformation. Above the man's head, a blue floating name tag read: [DAVE_THE_DISRUPTOR - LVL 2 WARRIOR].

"Die, you rotters!" Dave yelled, a manic, terrified grin on his face. He turned his sword toward a teenager cowering in the corner. "The System says I get XP for every one of you I clear!"

"Wait!" the kid screamed. "I'm not sick! I'm"

Dave didn't wait. He lunged.

Kade’s jaw tightened. The "System" wasn't just a game; it was an invitation for the world to lose its mind. And according to that System, Kade was the ultimate prize.

He looked at his own hands. The violet veins were pulsing faster now.

[NEW SKILL AVAILABLE: ZOMBIE TREE]

[SKILL: INFECTIOUS COMMAND (RANK F)]

Description: Direct the hunger of those lower than you.

Kade looked at the "Mindless Drones" wandering the lobby, then back at Dave, who was eyeing a fresh group of survivors.

"You want a monster?" Kade whispered, his voice dropping into a register that sounded like grinding stones. "I'll give you a monster."

He pushed the door open and stepped into the chaos of the lobby. He didn't run. He walked.

"Hey, Dave!" Kade shouted.

The warrior turned, his glowing sword humming. He saw Kade the grey skin, the violet eyes, the Level 0 tag.

"Whoa," Dave grinned, his eyes widening with greed. "A named mob? In the tutorial? Talk about a jackpot."

Kade didn't flinch. He reached out with his mind, grabbing that magnetic hum he had felt in the morgue. He didn't just feel the zombies in the room; he felt their emptiness. Their void. And he filled it with a single, burning thought.

Eat.

Across the lobby, six zombies froze. Their heads snapped toward Dave.

"Jackpot's closed, Dave," Kade said.

As the horde lunged, the ceiling above them groaned. The red lattice hissed, and a massive, shimmering portal began to tear open in the center of the lobby.

A voice, booming and ancient, echoed through the halls, overriding the screams.

[WORLD EVENT: THE CROWN ASCENDS]

From the portal, a hand made of pure, calcified bone reached out, clutching the edge of reality.

Kade’s "Patient Zero" tag began to glow a violent, blinding purple.

[WARNING: THE CROWN ZOMBIE HAS DETECTED YOUR SIGNATURE]

[RUN, LITTLE PRINCE]

The floor beneath Kade's feet began to liquefy into black ichor, and the "Jackpot" Dave was suddenly the least of his worries.

Kade looked at the portal, at the thing coming through, and realized that escaping the morgue had been the easy part.

The heart of the hospital let out a final, mechanical scream, and the lights went out.
