Project Zero: Evolution Protocol

First Sample

He had crept to the service stairwell on his good leg, ten minutes of dragging breath and held steps, past silent doors and the dead shapes of things that had once been staff. The facility had gone quiet in a way he didn't trust. Quiet like a held breath. Quiet like something waiting for him to make a mistake.

The stairwell was a dead end. That was the point. A narrow concrete shaft behind a steel door, tucked between the morgue and the boiler room, with one way in and one way down. No windows. No cameras. A single caged bulb that buzzed like a trapped wasp.

Cyrus wedged the axe haft through the door handle, kicked a rusted bucket against the bottom for good measure, and slid down the wall until he hit the floor.

"Home sweet f*****g home," he muttered.

He laid it all out in front of him like a man preparing for surgery. The pistol. Eight rounds. The axe. The bleach bottle, nearly empty. The notebook with its dead men's handwriting. The gold keycard.

And the thing in the gauze.

He didn't touch it yet.

NOT YET, the tag had said. Lopes was out there somewhere, scratched his way out of a drawer, alive or something close to it, and Cyrus couldn't find him with a body that was bleeding out and blind.

Eight hours. Nine. That was the price of being useful.

First, the leg.

The morgue had a first-aid cabinet bolted to the wall, and he had stripped it down to the screws. Antiseptic. Gauze. A curved needle and a spool of black surgical thread. He hadn't stitched anything since a bad night in a worse country, and then it had been someone else's leg.

He cut away the sodden scrub strip. The wound underneath was long, red and gaping, the edges puffy, the muscle shining wet. It hadn't closed. It hadn't even tried.

"Fractured," Cyrus said. "Functional. Fucked."

He poured the antiseptic over it and bit down on his sleeve.

The scream came out anyway, a strangled, animal sound that bounced off the concrete and rang in his teeth. He rode it out. Then he threaded the needle with shaking fingers.

The first stitch went in like a hot nail.

"Son of a b***h. Son of a b***h. Son of a motherfucking bitch."

The second was worse. By the sixth he was soaked in sweat, his vision blurring at the edges, his own voice reduced to a steady, vicious chant of obscenities. By the twelfth he'd stopped swearing and started counting, because counting was the only thing that kept him in the room.

Twenty-two stitches. He tied off the last one with his teeth.

He lay back on the concrete, panting, and stared at the buzzing bulb.

"Okay," he said. "Okay. That's the easy part."

He sat up and unwrapped the gauze.

The organ had changed. It had been pale and wet in the lab, a fist of ridged meat. Now it was a darker, bruised gray, the ridges tighter, the surface glistening as though it were sweating. It pulsed. Slow and steady. Still alive, hours later, still f*****g alive.

Blue letters rose in the corner of his eye.

[SAMPLE ANALYSIS: COMPLETE]

[SOURCE: ADAPTED, SCENT TRACKER]

[VIABLE MUTATIONS: 2]

"Here we go."

[1. PREDATOR: PULSE SENSE]

[Detect heartbeat and respiration within approximately 15 meters. Passive. Always active once integrated.]

[COST: SENSORY OVERLOAD. INCREASED CALORIC DEMAND.]

[2. PREDATOR: SCENT TRACE]

[Track blood, sweat and fear across long distances. Identify individuals by chemical signature.]

[COST: SEVERE APPETITE ESCALATION. INCREASED AGGRESSION.]

[WARNING: INTEGRATION WILL REDUCE GENETIC STABILITY. EFFECT IS PERMANENT.]

Cyrus read it twice.

Then a third time, slowly, the way you read a contract you were about to sign with a gun to your head.

"Aggression," he said. "Appetite. Yeah, f**k that. I'm already hungry enough to eat a goddamn horse."

His eyes slid back to option one.

Heartbeats. He would hear them. Anything alive within fifteen meters, behind a wall, around a corner, in the dark. A woman who learned tactics could stand perfectly still and he would still know exactly where she was.

It was the best intelligence he'd ever been offered, and it came from the thing that wanted him to evolve.

"You want me to pick," he said to the letters. "You want me to say yes."

The letters pulsed.

"What happens if stability hits zero?"

[DATA UNAVAILABLE]

"Of course it's unavailable, you useless f*****g prick."

"Fine. But I'm not doing it for you." His jaw set. "I'm doing it because I'm tired of walking into rooms blind."

He selected the first option.

[CONFIRM? Y/N]

"Yes."

[INTEGRATION STARTED. ESTIMATED DURATION: 8 HOURS, 58 MINUTES]

[SYNTHESIS METHOD: INGESTION]

Cyrus stared.

"Ingestion."

He looked down at the organ.

"You have got to be f*****g kidding me."

The system said nothing.

He picked it up. It was warm now, warmer than his hands, and it throbbed against his palm like something that wanted to be eaten. His stomach clenched, hard and bright, the way it had in the morgue, and this time it wasn't a warning. It was a prayer.

He hated how badly he wanted it.

"Don't think about it," he told himself. "Just do it."

He closed his eyes and bit down.

It tasted like copper and cold meat and something sweeter underneath, a taste with no business being delicious. He chewed twice and swallowed hard. The next bite went down easier. By the third he was ripping at it with both hands, shoulders hunched, a feral little animal in the dark.

He finished it in under a minute.

He sat there afterward with his hands slick and his face wet, shaking, bile rising at the back of his throat.

He thought of Brandt, twenty-three, the kid who wrote postcards to his mother. He wondered what Brandt would have said if he could see this.

"Sir," Brandt would have said, gently, "please stop eating the thing."

Cyrus wiped his mouth on his sleeve. It left a dark smear.

"Jesus Christ," he whispered. "What the f**k have I done?"

The first wave hit him like a train.

Fever, all at once. His skin went tight, then burning, and sweat poured down his ribs in sheets. His joints locked. His ears began to ring, high and thin, and then the ringing deepened into something heavier. Something with a rhythm.

Something wet trickled over his lip. He touched it. Red.

A nosebleed. His own blood, bright on his fingertips.

"No," he rasped. "No, no, don't you f*****g dare." He clamped his sleeve over his nose, pinched the bridge until stars popped, and prayed to nothing in particular that every scent-tracker in the building had died in that vent.

[MUTATION IN PROGRESS: PULSE SENSE]

[TIME REMAINING: 8:57:12]

[GENETIC STABILITY: 94% → 91%]

He slumped sideways against the wall, vision swimming.

And then he heard it.

Not with his ears. Deeper than that. A pulse, slow and thudding, felt through the concrete and the bones of his jaw, like a drum heard through water.

One heartbeat.

Then ten.

Then a hundred.

Close, in the walls, three small ragged beats, quick and ugly and out of time: Hollowed, twelve meters away, shuffling through the boiler room. He could hear them breathe. He could count them.

Beneath those, deeper, steadier, the vast chorus.

He gasped. The world was full of them, a vast soft chorus rising through the floor, hundreds upon hundreds of hearts, all beating at once. And they weren't random. They weren't overlapping like a crowd. They were perfectly, horribly, in sync.

Thud-thud. Thud-thud. Thud-thud.

Two thousand hearts. One beat.

Cyrus pressed his palms to his temples and tried to breathe. It was too big. He could feel every thud in his teeth, in his spine, in the wet roots of his eyes, and the harder he tried to shut it out, the louder it got.

"Turn it off," he begged the letters. "Turn it the f**k off."

[PASSIVE ABILITY. CANNOT BE DISABLED.]

"Of course not."

And under the pain, under the fever, the worst part: he was still hungry. He had just eaten a fist of raw meat, and his stomach was screaming for more.

Then he noticed the sound under the sound. A single heartbeat. Close. Right in the middle of his chest.

His own.

It was slowing down.

Thud-thud. Thud-thud.

It was matching theirs.
