The Grey Pulse
I arrived on the rooftop, the heavy metal door clanging shut behind me. No one was here.
Perfect. I needed the silence.
I leaned my weight against the rusted railing and looked down at the sprawling landscape of the city. It never stopped; it was a machine that was always moving, always humming. It was alive, but in a cold, artificial way that made my skin crawl.
I let out a long, jagged sigh. I was just another gear in that machine, wasn't I?
Right after graduation, I had stepped into this cycle. It had been three years of the same grey rhythm. I woke up, forced down breakfast, and ran. I’d grab something for lunch on the way, arrive at this glass-and-steel cage, and work until my eyes burned. I spent my afternoons listening to the verbal sewage spewed by a mannerless beast I was forced to call a "boss." Then, I’d return to my small apartment, eat something unmemorable, and sleep. My colorless life continued, day after day, in this artificial city.
I reached into the crinkled paper bag and pulled out a burger. "Sorry, buddy," I muttered to the sandwich. "You’re my lunch today. I know you were constructed in a careful, artistic way, but I need to consume you now. Your sacrifice will give me enough energy to survive until dinner. Rest in peace....in my stomach."
As I opened my mouth to take a bite, a thought knocked on the back of my mind.
Is this a sacrifice?
Mr. Burger never agreed to be my lunch. He was forced into this destiny. He had no choice. This wasn't a noble sacrifice at all. It was murder, cold-blooded, empty-stomach murder. Mr. Burger was a victim, created solely to be eaten alive. Poor guy.
My extraordinarily important philosophical debate was shattered by a sudden, violent roar of noise from the street below. High-pitched screams began to puncture the hum of the city.
Another accident? I leaned further over the railing to see.
A man was lying in the middle of the street, but he wasn't alone. Another man, one filled with a terrifying, animalistic rage, was pinned on top of him, his teeth buried in the first man's shoulder. A crowd had gathered, people shouting and trying to pull the aggressor away. The commotion had already caused a massive traffic jam; cars honked and people leaned out of windows, oblivious to the horror unfolding.
The rage-filled man suddenly lunged, snapping at a woman who was trying to help. The original victim on the ground was suffering, his body twisting in a series of grotesque, unnatural spasms. Then, with a suddenness that made my stomach drop, the victim stopped twitching. He flipped over and instantly attacked the person closest to him.
Chaos exploded like a bomb. People started running in every direction. Every person who was bitten seemed to turn within seconds, their bodies contorting as they dropped to the ground. They weren't running like humans anymore; they were moving on four limbs, scuttling like predatory insects. Two of those rage-filled things....those Crawlers burst through the glass lobby doors of my office building.
My senses finally returned.
The door!
I sprinted across the rooftop, my heart hammering against my ribs, and slammed the heavy door shut, throwing the bolt just as a muffled scream echoed from the stairwell below.
A zombie apocalypse? Now?
I hadn't even had the chance to buy a car yet. I was going to die in my work clothes because of a biological glitch.
The screaming inside the building started loud, a chorus of terror and tearing flesh. But I didn't move a muscle. I sat with my back against the rooftop door, hearing screaming and the noises of footsteps in down floor.
The human screams faded into a sickening silence, replaced only by the dry, clicking noises of the monsters. I stood up and looked back down at the street. The horror was total. The city was no longer moving; it was being hunted. Those things were everywhere, scuttling on all four limbs, their heads twitching as they searched for anything left alive. Blood was painted across the pavement in dark, jagged streaks. Everything I knew was destroyed.
I pulled out my phone, turning the volume to the absolute lowest setting. I was terrified the Crawlers might be sensitive to sound. The news reporters were frantic, talking about an unknown virus. They said it was highly infectious, traveling through blood and saliva. Those Red-Eyed Devils could admit you to their "fan club" with just one bite.
I sat back down and ate half of my burger. It tasted like ash, but I needed the fuel.
Suddenly, my phone started ringing in my hand. I startled so violently I almost dropped it over the edge. I held my breath, hearing the sound of claws scuttling on the floor beneath the door. They had no idea I was up here yet, but the ringtone sounded like a siren in the silence.
It was a video call from my parents. They were in another country, thousands of miles away from this madness.
I answered, keeping my voice a trembling whisper. They were safe there, the news hadn't reached them yet, or the virus hadn't crossed the ocean. They were worried about me, sensing something was wrong. I forced a smile, assuring them I was okay, that I was just working late.
"I have to go, I love you," I whispered, cutting the call quickly. I had to save my battery. It was my only lifeline left.
As night fell over the burning city, I ate the other half of the burger in the dark.
In the morning, the air was cold and smelled of smoke and that sweet, chemical rot of starvation. I gathered my courage. I couldn't stay on this roof forever.
I didn't have the luxury to use the stairs when my meat loving coworkers were waiting eagerly to greet me. I began my descent in the hard way.
The descent from the rooftop wasn't a heroic leap; it was a grueling, terrifying exercise in gravity management. My college parkour days had been about flow and style, jumping over benches in a park for the thrill of the movement. This was different. This was a frantic struggle against metal that groaned under my weight and concrete that crumbled beneath my fingers.
I shimmed down a copper rain pipe, my heart hammering so loudly against my ribs I was certain the Crawlers could hear it. I stopped at the fourth floor, hanging by my fingertips from a window ledge.
Below me, in the narrow alleyway, three of them were breakfast. From this vantage point, I finally had a clear, unobstructed view of what the world had become.
They weren't the usual cinematic zombie. They were more like biological machines in total failure.
The virus seemed to have targeted the cerebellum, the brain's balance center, making upright walking impossible. To compensate, their bodies had adapted a four-legged gait. Their arms had elongated, the tendons pulling tight until their knuckles scraped the pavement. They moved with a jerky, insect-like efficiency, their spines arched in a permanent, agonizing curve. It wasn't human movement; it was a predatory skitter.
One of them looked up, and I nearly lost my grip on the iron railing. The news called them "Red-Eyed Devils," but there was no magic in those orbs. It was subconjunctival hemorrhage on a massive scale. The virus caused such extreme internal pressure and fever that the capillaries in their eyes had simply burst, drowning the whites of their eyes in a pool of fresh, vibrating crimson. They didn't glow; they bled from the inside out.
They didn't growl. Instead, they made a wet, clicking sound in the back of its throat. I noticed A thick, yellowish froth bubbled constantly from their lips, coating their chins and dripping. They didn't....maybe couldn't swallow. As they moved, they left behind a "snail trail", a mixture of this infectious saliva and a sour, acidic gastric sludge that hissed faintly against the cold concrete.
I realized then that they weren't searching for "brains." They were searching for anything that moved, driven by a "furious" phase of a virus that had stripped away their humanity and left only the predatory instinct to bite. They were fast, moving on all fours allowed them to distribute their weight, scuttling over rubble like oversized, hairless rats.
Even from this height, the stench was a physical blow. It wasn't just the smell of blood. It was the sharp, eye-watering sting of ammonia from concentrated sweat, mixed with a sickly-sweet, chemical odor like rotting apples. It was the smell of ketosis, their bodies were literally eating their own fat and muscle to fuel the "furious" rage of the virus.
I looked away, my stomach churning. They weren't ghosts or demons. They were humans whose 'engines' had been hijacked by a virus and reprogrammed into a living gruesome nightmare.
I remained like a statue until those creatures finished their meal and skittered away,
I navigated the ruins of the neighborhood, my heart stopping every time a piece of glass crunched under my boot.
I reached the second-floor balcony of my own building. I gripped the railing, my muscles screaming in protest, and hauled myself up. I didn't use the front door; that was a bottleneck for death. Instead, I moved along the narrow concrete lip of the building’s exterior, pressing my chest against the brick as I shimmied toward my own window.
I could see into the neighboring units as I passed. In 2B. There was no movement, only the eerie silence of a home that had become a tomb.
Finally, I reached my window. I’d left it cracked an inch for ventilation before the world ended, a rare moment of luck. I slid it upward, the friction making a high-pitched screee that sounded like a gunshot in the quiet.
I froze. I waited for the scuttle. I waited for the red, burst-capillary eyes to find me.
Nothing.
I tumbled inside, landing on my rug with a muffled thud. I kicked the window shut and locked it, my forehead leaning against the cool glass. I was home. I was safe.
Or so I thought.
The floorboards behind me creaked. The air in the room didn't smell like my apartment; it smelled like rain and a faint, floral perfume that didn't belong in my bachelor pad.
I turned slowly, fearing the worst.
But my heart stopped in a completely different way.
A woman was standing in the center of my kitchen. She was wearing a vibrant yellow top that seemed to glow in the dim light, and her auburn hair was a messy, fiery crown around her pale face. She didn't look relieved to see me.
She pointed a kitchen knife at me, her hand steady despite the fear in her eyes.
"Hey," she rasped, her voice sharp. "Are you bitten?"
