The steel door behind us didn't fail all at once. It died screaming.
We were halfway down the corridor when the hinges finally shore away with a sound like a gunshot, followed by the wet, heavy thud of the door hitting the concrete floor. Then came the scrambling—the frantic, scurrying sound of claws on linoleum, moving faster than any human legs were meant to move.
"Run," I choked out.
It was a redundant command. Hailey was already moving, her sneakers squeaking on the polished floor. I was the anchor. I was the dead weight.
My body was a riot of conflicting biological failures. The hunger in my gut was a physical vacuum, a black hole trying to suck my ribcage inward. The heat was rising, turning my blood into slow-moving sludge. And the empathy... that was the worst.
Even with the mental barrier I was desperately holding in place—a crude, psychic dam made of stolen alien instinct—the noise leaked through.
I could feel the thing chasing us.
It wasn't thinking. It wasn't planning. It was just a jagged, red spike of pure need. It was hungry. It was cold. It wanted to fill the void inside itself with warm meat.
"The cage!" I shouted, pointing a shaking finger ahead.
The janitor's cage was a chain-link enclosure blocking the entrance to the service tunnels. It was locked, obviously. A heavy padlock secured the sliding gate.
Hailey didn't slow down. She didn't look for a key. She didn't panic.
She adjusted her angle.
"Move," she hissed.
I threw myself against the wall to get out of her way.
Hailey hit the chain-link gate at a full sprint.
Just before impact, I saw the ripple—the grey, chitinous wave surging under the skin of her shoulder and arm. It wasn't magic. It was rapid, violent biological calcification.
CRASH.
The metal groaned and snapped. The padlock didn't break; the entire hasp tore out of the concrete wall. The gate twisted inward, mangled like aluminum foil.
Hailey stumbled through the wreckage, her momentum carrying her forward into the darkness of the tunnel mouth. She spun around, chest heaving, her eyes wide and terrified.
"Femi! Inside!"
I scrambled through the twisted metal, snagging my hoodie on a sharp edge of chain-link. I ripped it free and fell into the tunnel.
"Block it," I wheezed. "Push it back."
Hailey grabbed the mangled gate with her bare hands—hands that were currently encased in thick, grey ridges of bone—and shoved it back into the frame. She bent the metal edges, jamming them against the concrete to create a crude barricade.
Seconds later, a shape slammed into the other side.
It was the Husk. The thing that used to be Josh.
It threw itself against the chain-link, snarling and spitting. Through the mesh, I saw glimpses of it in the red emergency light. Its eyes were gone—just black pits. Its jaw was distended, unhinged.
"OPEN," it shrieked, the voice oscillating between a guttural roar and Josh's terrified tenor. "HAILEY... IT HURTS... LET ME IN..."
Hailey flinched, stepping back, her hands trembling. The grey armor on her knuckles was receding, steaming slightly in the cool tunnel air.
"Don't listen," I said, my voice flat. I squeezed my eyes shut, reinforcing the mental barrier. The empathy coming off the thing was toxic—a mix of animal hunger and the echoes of Josh's dying fear. "It's a lure. It's mimicry. Ignore it."
The Husk thrashing against the gate didn't have the mass to break through the jam Hailey had created. It was fast, agile, but lacking the brute force required to breach the barricade. It clawed uselessly at the wire, snapping its teeth.
"Come on," I said, pushing myself off the wall. "We need distance."
The service tunnel was a different world.
It was narrow, lined with hissing steam pipes and bundles of thick electrical cables. The air smelled of damp concrete, rat poison, and ozone. It was dark, lit only by flickering fluorescent tubes spaced twenty meters apart.
We jogged—or rather, limped—deeper into the underground network.
"How far?" Hailey asked. Her voice was hollow. She was wiping her hands on her jeans repeatedly, trying to clean off the memory of the door handle.
"Cafeteria sub-basement is roughly two hundred meters north," I said, visualizing the campus blueprints I'd memorized during freshman orientation. "There's a dry storage pantry. Canned goods. High-calorie density."
"Food," she whispered. "I'm starving."
"Me too."
That was an understatement. My hunger wasn't just an appetite; it was a survival threat. My vision was swimming. If I didn't get calories soon, my own biology would start consuming my muscle mass for fuel.
We moved in silence for a minute, the only sound the distant hum of the campus generators and the rhythmic thump-thump-thump of my own heart.
Then, I stopped.
"Wait."
Hailey froze instantly. "What? What is it?"
I pressed my hand against a cold water pipe, steadying myself. I lowered the mental barrier just a fraction—a dangerous gamble.
The psychic noise flooded back in. Pain. Confusion. Hunger.
But I wasn't listening for the chaos above. I was listening for proximity.
...scrape... click... hiss...
It wasn't a sound. It was a pressure on the mind. Sharp. Jagged. Close.
"Ahead," I whispered. "Wait, no. Two sources. One weak, one... heavy."
I squinted into the gloom ahead. The tunnel branched off to the right, leading toward the boiler rooms.
From the shadows of the branch, a figure stepped out.
It wasn't running. It was shambling.
It was wearing the tattered remains of a janitor's uniform. It was big—naturally big, maybe a weightlifter in its former life—but the mutation had warped it. One shoulder was grotesquely swollen, covered in that familiar grey plating.
A Juggernaut Husk. Or at least, a partial one.
It stopped when it saw us. It didn't scream. It just turned its head slowly, the vertebrae grinding audibly.
"Back up," I said, grabbing Hailey's arm.
But behind us, from the way we came, came a low, chittering sound.
I spun around.
A Leecher Husk—smaller, faster—dropped from the overhead pipes, landing on all fours like a spider. It was naked, skin pale and translucent, ribs showing. Its mouth was a bloody ruin.
Pincer movement.
"Trapped," I muttered.
My heart rate spiked, triggering my internal weakness. My temperature surged. Sweat broke out instantly on my forehead. My glasses fogged up.
"Femi?" Hailey backed into me. We were standing back-to-back in the narrow corridor.
"The big one is slow," I said rapidly, my brain analyzing the threat vectors despite the heat haze. "The small one is the immediate threat. It will jump."
"I can't fight them," Hailey whimpered. "I can't do it again."
"You don't have a choice," I snapped. "You are the tank. I am... currently compromised."
The Leecher hissed and lunged.
It covered the ten meters between us in a heartbeat, a blur of pale limbs and teeth.
"Hailey, duck!"
She didn't duck. She froze.
The Husk collided with her, knocking her backward. They hit the floor in a tangle of limbs.
"Get off!" Hailey screamed, thrashing.
The Husk was snapping at her face, its teeth clicking inches from her nose. It was pure, feral violence.
I stepped forward, intending to kick it, to do something, but a wave of dizziness hit me. The hunger inside me saw the Husk not as an enemy, but as... meat.
Eat it. Consume. Restore energy.
The instinct was so loud I nearly vomited. It was vile, a betrayal of my own humanity.
"NO!" I yelled, kicking the Husk in the ribs.
It felt like kicking a bag of cement. It barely registered. The Husk swiped backhand at me, its claws tearing through my jeans and slicing my shin.
Pain. Sharp and hot.
But the pain snapped Hailey out of her paralysis.
She saw the blood on my leg.
Her eyes changed. The fear vanished, replaced by a sudden, cold fury.
CRACK.
A sound like a gunshot echoed in the tunnel.
Hailey had grabbed the Husk by the neck. Her hand was encased in full armor plating—thick, jagged grey rock. She squeezed.
The Husk's windpipe collapsed.
She didn't stop. She lifted the creature—which must have weighed seventy kilos—off her body with one hand and slammed it into the concrete floor.
THUD.
She slammed it again.
THUD.
And again.
SPLAT.
The creature stopped moving. Its head was... gone. It's brain matter splattered on the concrete.
Hailey scrambled backward, crab-walking away from the corpse, her chest heaving. Steam was rising from her arm in thick, white plumes.
"Behind you!" I yelled.
The Juggernaut Husk—the janitor—had closed the distance. It was slow, but it was massive. It raised a fist like a sledgehammer.
Hailey was on the ground. She couldn't dodge.
"Hailey, brace!"
She crossed her arms over her head instinctively.
The grey armor flashed into existence, covering her forearms and shoulders in a split second, interlocking like tectonic plates.
WHAM.
The Janitor-Husk's fist connected with Hailey's guard.
The impact shook the floor.
Hailey didn't break. She didn't even buckle. The armor absorbed the kinetic energy completely. She groaned, the floor cracking beneath her back, but she held.
She roared—a primal sound of exertion—and kicked out with both legs.
Her feet caught the heavy Husk in the knee.
SNAP.
The creature's leg bent backward. It toppled over like a felled tree, crashing down beside her.
Before it could recover, Hailey rolled on top of it. She didn't strike. She just... pressed.
She placed both armored hands on the Husk's chest and pushed.
I watched, horrified and fascinated, as the armor on her arms flared, the muscles bunching. The Husk's ribcage gave way with a sickening, wet crunching sound. The chest cavity collapsed.
The Janitor stopped moving.
Silence returned to the tunnel, broken only by the hiss of steam and Hailey's ragged breathing.
She sat there, straddling the dead monster, her arms encased in steaming grey rock. She looked at her hands, then at me.
"I..." she started, her voice trembling.
"Status check," I interrupted, leaning against the wall to keep from passing out. The heat in my body was unbearable. I needed to cool down. "Any bites? Scratches?"
She checked herself. "No. Just... bruised."
"Good." I slid down the wall, clutching my bleeding shin. "Threat neutralized."
"Neutralized?" She laughed, a frantic, high-pitched sound. "I just crushed a guy's chest like a soda can, Femi! I'm a freak!"
"You're alive," I corrected. "And so am I. That is the only metric that matters right now."
I pointed down the tunnel. "The pantry. We need to move before the noise attracts more."
She stood up, the armor slowly receding into her skin. She looked exhausted, her face pale, sweat dripping from her nose. The heat was hitting her now.
She walked over to me and offered a hand. It was hot to the touch, like she had a high fever.
"Can you walk?" she asked.
"If I have to crawl, I will," I muttered, taking her hand. "I need sugar."
We made the last fifty meters in a stumbling daze.
The door to the sub-basement storage was a standard fire door. It wasn't locked. We pushed inside and barricaded it with a heavy metal shelf loaded with industrial-sized cans of tomatoes.
The room was cool. Smelled of dust and dried pasta.
I scanned the shelves. My eyes locked onto a box of energy bars—cheap, bulk-buy chocolate and oat bars.
I didn't wait. I tore the box open.
My hands were shaking so bad I could barely unwrap the first one. I shoved the whole thing in my mouth. It tasted like sawdust and chemicals. It was the best thing I had ever eaten.
I ate three in thirty seconds.
The knot in my stomach loosened slightly. The black hole receded. My vision cleared.
I looked over at Hailey. She was sitting on a sack of rice, holding a can of peaches she'd opened with her thumb. She was drinking the syrup, eyes closed.
"Better?" I asked, wiping crumbs from my mouth.
She nodded slowly. "Yeah. The heat... it's going down."
"Good."
I leaned back against a shelf, adjusting my glasses. My leg throbbed, but the bleeding had slowed.
We were safe. For five minutes.
"Okay," I said, my voice steadier now. "First objective complete. We have resources."
"What's the next objective?" Hailey asked, looking at me with a mix of fear and reliance.
I looked around the room. There was a service elevator at the back (useless without power) and a stairwell leading up to the kitchen.
"We need information," I said. "We know what the enemy is. We know what we are. But we don't know the territory."
I pressed my hands against my temples, fighting the dull, constant pressure of the psychic noise that never ended.
"First, we survive the internal fight," I continued, my voice tight. "The constant heat and the hunger are draining our resources faster than we can replenish them. We are both unstable."
"The pain?" Hailey asked, watching my hands.
"That's the constant," I said, dropping my hands. "But the energy debt is not. If I keep losing control to the hunger, I become a liability. If you keep activating your armor and instantly overheat, you become dead weight."
I looked at her, my voice turning cold and tactical. "We have to stabilize the viral side effects before we can even attempt to leave this basement."
"So, what's the plan? We just wait?"
"No. We adapt," I said, my gaze hardening. "We have two weeks of food here, tops. We spend that time learning control. You need to practice your thermal regulation—how to use the armor without spiking a fatal fever. And I need to practice the Filter, so the screams and pain don't blind me when we run into trouble."
I grabbed the last energy bar. "We aren't students anymore, Hailey. We're an unstable biological system. And if we want to survive what comes next, we need to stop breaking and start functioning."
I handed her a bottle of water. "Eat up. We start in an hour."
