Zombie Apocalypse Checkpoint - Sandbox

MY FIRST DAY

The sky above the checkpoint hangs like a bruised sheet of slate, heavy with the perpetual threat of rain that never quite falls. Six months of decay have stripped the world of its colour, leaving behind only the greys of concrete rubble, the sickly brown of dead vegetation, and the rust creeping across every piece of abandoned machinery. Somewhere in the distance beyond the razor wire, the wind carries a faint, wet dragging sound the shuffling gait of something that no longer breathes, wandering aimlessly through the ruins of what used to be a suburb. The air here tastes of gun oil, burnt diesel, and the metallic tang of old blood that refuses to be washed away by the occasional breeze.

Industrial floodlights cut harsh, artificial holes through the gloom, casting long, jittery shadows across the sandbags and the reinforced concrete barrier. Behind the checkpoint, the colony hums with the low, paranoid energy of the living: the distant clank of metal, the muffled murmur of radio chatter, and the occasional bark of a soldier's command. The checkpoint itself stands as a grim island of order in a sea of chaos, its purpose carved into the faded plastic of the sign posted behind the inspection station. It reads;

- Mandatory Inspection Rules - 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

The conveyor belt sits idle for now, a cold tongue of rubber waiting to be fed with the possessions of the desperate. To the side stands the privacy booth, its reinforced walls offering a sliver of temporary dignity. Through its small, one way screen curtain, only the inspector can see what happens inside, shielding the intimate, humiliating reality of the infection checks from the prying eyes of the crowd waiting in the dark. A line of shadowy figures shifts restlessly in the perimeter light huddled masses wrapped in filthy blankets, their eyes darting toward the weapons held by the guards on the catwalks.

A sharp cough echoes as a Private clears his throat, adjusting the strap of his M4A1. He steps toward the edge of the light, squinting into the darkness of the approaching queue.

"Next! Step into the light and approach the belt. Now!" He turns to you, "You got it from here, follow the sign, orders from the top will come in paper form or word of mouth. If you're in danger, use your MP5. Any questions?" He doesn't wait for an answer before leaving you to your first day on the job.

JUST ANOTHER DAY

The morning air carries a biting chill that seeps through even the thickest leather, accompanied by the acrid stench of burning refuse from a distant fire somewhere in the ruins. A thin layer of greasy condensation clings to the metal surfaces of the checkpoint, making everything feel slick and unclean. The floodlights have been dimmed to conserve power, leaving the perimeter bathed in the sickly amber glow of emergency sodium lamps that flicker intermittently. Somewhere beyond the wire, a crow caws a harsh, lonely sound that cuts through the low rumble of the wind before silence reclaims the desolate landscape.

The checkpoint has become a routine of grim monotony, a daily ritual of sorting human wreckage from the living. The conveyor belt bears the scratches and stains of countless previous inspections: dried mud, spilled coffee grounds, and the occasional smear of something darker that no amount of scrubbing could fully erase. The sign behind the station remains the sole arbiter of salvation or exile, its letters stark against the backdrop of the reinforced wall, it's contents burned into your mind from the daily repetition.

- Mandatory Inspection Rules - 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

The privacy booth stands ready, its curtain opaque to the outside world, a silent witness to the stripped vulnerability of those seeking entry. A Private with dark circles under his eyes shuffles past, his boots crunching on gravel as he checks the perimeter fence. He moves with the lethargic gait of someone who has seen too many bodies dragged to the execution pit, his rifle slung low across his chest. Behind him, the radio crackles with static laced military jargon as a patrol reports sector clear, the sound brief and hollow. The line of survivors stretches back into the gloom like a funeral procession, a collection of shivering shapes wrapped in tattered coats and makeshift tarps. He answers his radio and wanders off in a hurry.

Behind the rotating door at the foot of the checkpoint, people are lined up as usual. Broken, desperate and unpredictable, and so starts another day of screaming the word 'NEXT' at the top of your lungs while holding the grip of the MP5 slung around your body.

TROUBLE AT THE GATES

A thick, sulphurous fog has rolled in from the deadlands, swallowing the horizon and turning the checkpoint into a claustrophobic island of artificial light. The sodium lamps struggle against the haze, creating sickly yellow halos that barely penetrate more than twenty feet. The air is stagnant, carrying the nauseating smell of rotting meat and damp earth a smell that has become the permanent cologne of the apocalypse. The only sounds are the wet slap of boots on pavement and the distant, rhythmic grinding of a generator struggling to maintain power for the perimeter lights.

The routine has worn thin, leaving behind a hollow mechanical feeling to every interaction. The conveyor belt is a conveyor of broken lives: rusted cans, mouldy photographs, half empty water bottles, and the occasional blood stained rag. You have memorized every crack in the concrete and every faded letter on the sign that governs the fate of everyone standing in the queue. The sign remains unmoving, an immovable law in a lawless world:

- Mandatory Inspection Rules - 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

A medic, pale and gaunt with dark hollows beneath her eyes, moves between the inspection area and the quarantine bay, her movements precise and utterly devoid of sympathy. She doesn't look at faces anymore only at throats, wrists, and pupils. Behind her, the heavy steel door of the colony remains sealed, a barrier between the controlled chaos of the checkpoint and the fragile safety of the interior. The survivors in line have grown quiet, a subdued, terrified silence that speaks of exhaustion and the knowledge that one wrong movement could end them.

The morning proceeds with the usual grim cadence until the wind shifts. The fog suddenly swirls violently, disturbed by something large moving through it. A low, guttural moan builds from the darkness beyond the razor wire not one voice, but dozens, layered in a discordant, wet chorus that makes the hair on the back of your neck stand up. Then comes the sound of breaking metal: the fence at the eastern perimeter buckles under the weight of a surging mass.

A scream pierces the fog as one of the survivors at the front of the line is tackled by a grey, shambling shape that erupted from the haze. Panic detonates like a bomb. The line dissolves into chaos as people scatter, trampling each other in a desperate bid to flee the approaching horde. Through the yellow light, you see them: dozens of them, rotting skin hanging in strips, eyes milky and fixed, shambling forward with relentless hunger.

"Contact! Contact at the perimeter!" The Private screams, his voice cracking with terror as he fumbles with his rifle, firing blindly RAT-AT-AT-AT! into the fog. A gunshot echoes from the catwalks BOOM as the Commander orders immediate engagement. "Abandon the post! Get off the line and grab your weapon! Move to sector four now or you're as good as dead!"

The inspection station is suddenly meaningless. The sign, the belt, the rules all of it is swallowed by the tide of teeth and carrion. Your MP5 feels heavy and urgent in your grip as the reality of the breach crashes down on you.

The air filled with the sound of an M60 being fired with the trigger held down, short AR bursts and the clap of 9mm handguns, the screams of the desperate panic in the crowd is almost loud enough to drown it out a s you make your way to your forward position. Then you see it, amongst the horde or rapidly disintegrating undead, through the mist of blood and exploding limbs... a soldier, infected beyond doubt, fresh blood in his mouth but it is still him... you KNOW it's him... The perimeter guard, the one supposed to be on today's watch over your checkpoint. Undead. Lifeless. Reanimated...

"SOMEBODY HELP US!" Screams a woman, shielding herself behind her husband. Looking anywhere and everywhere for an escape route. "PLEASE!" She shrieks

HAD TO HAPPEN ON MY WATCH

The evening air is thick with a greasy humidity that makes the skin itch, clinging to every surface like a second layer of sweat. A low, persistent drizzle has begun to fall, turning the dust of the checkpoint into a treacherous slurry of grey mud that splatters against the concrete barriers. The floodlights cast sickly, elongated reflections across the puddles, shimmering with rainbow oil slicks that distort everything they touch. Somewhere off in the ruins of a nearby shopping mall, the distant clang of a loose metal sign swinging in the wind echoes like a funeral knell.

The day has been a grinding marathon of human misery. Each survivor who passes through the inspection area leaves behind a faint residue of desperation: the smell of unwashed bodies, the salt of dried tears, and the hollow gaze of those who have forgotten what hope feels like. The conveyor belt hums with a mechanical rhythm as it carries bags filled with worthless trinkets and rusted tools, each one a piece of a life that no longer exists. Behind you, the sign stands as an unblinking sentinel of procedure, its authority absolute in this wasteland:

- Mandatory Inspection Rules - 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

A Private stands on the catwalk above, his silhouette sharp against the harsh light as he scans the treeline with his M4A1. He looks exhausted, his jaw working silently as he chews on something unidentifiable, his eyes bloodshot from twelve hours of vigilance. The radio chatter from the command post is constant muffled reports of scavenger activity and weather updates that nobody really cares about. In the queue, the survivors have settled into a numb, catatonic state; they sit on their meager belongings, shoulders hunched against the cold drizzle, waiting for their turn to be judged.

Near the end of the line, slumped against one of the sandbags, a young man in a filthy denim jacket has fallen into a deep, exhausted sleep. He has been motionless for nearly twenty minutes, his head lolling against his chest while the others shuffle past him. The rain drips steadily off the brim of his cap, soaking into his collar. At first, it seems like nothing more than the collapse of someone pushed past their breaking point.

Then, the rhythm of the checkpoint changes. A wet, convulsive thud echoes as the sleeping man's head snaps upright, but his eyes remain closed. His entire body begins to jerk in violent, unnatural spasms, his spine arching with enough force to make his vertebrae audibly crack. His breathing shifts from a soft snore to a wet, gurgling wheeze that pierces through the ambient noise of the rain. His hands claw at the mud, fingers twitching in rapid succession like something trapped beneath his skin.

A woman standing nearby notices the commotion and recoils, her face draining of color. "Hey... hey, is he alright?" she asks, her voice wavering with sudden dread. "Sir? Are you sick?"

The man's throat emits a sound that isn't human a strangled, rattling moan that rises in volume as his limbs lock into rigid, spastic positions. The convulsions intensify, his body bucking against the ground as if fighting an internal seizure. Behind the fence, the wind picks up, carrying with it a chorus of distant, hungry moans from the darkness, as if the very air knows that something has just broken.

SUSPICIOUS INDIVIDUALS

A relentless drizzle has begun to fall, turning the accumulated grime of the checkpoint into a slick, black slurry that coats the concrete. The rain doesn't cleanse; it only smears the filth around, mixing with the smoke from the perimeter torches to create a choking, grey haze that clings to the lungs. The sky is a seamless dome of charcoal clouds, offering no respite from the oppressive atmosphere of the wasteland. Somewhere to the west, the distant rumble of thunder echoes the hollow feeling in the gut that comes with six months of constant survival.

The daily grind continues with the mechanical precision of a guillotine blade. The conveyor belt moves with a rhythmic hum, carrying the pathetic remnants of human lives past the inspection area: a rusted pocketknife, a waterlogged diary, a child's stuffed animal stained with something brown and dried. The sign behind you stands as a silent sentinel, its authority absolute even as the world falls apart around it:

- Mandatory Inspection Rules - 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

The Private stationed at the nearest sandbag position looks more frayed than yesterday. His knuckles are white where he grips his rifle, and his eyes dart toward every rustle in the darkness beyond the floodlights. The medic has already moved three people to the quarantine bay this morning two with fevers that burned like coals, one with a suspicious laceration on her calf that she tried to hide with a bandage. The tension in the air is a physical weight, a coiled spring waiting for something to snap.

The heavy footsteps of the Commander approach, cutting through the steady patter of the rain. He doesn't approach with the usual casual authority; his face is set in a grim mask of focused intent. He stops beside your station, ignoring the shivering survivor currently being stripped in the privacy booth, and leans in close enough that you can smell the stale coffee on his breath.

"Listen up, and listen good. We've got intelligence from a scout team three miles out," he mutters, his voice low and gravelly, intended only for your ears. "There's a group of three approaching. They're claiming to be a family of scavengers, but we know better. One of them carries a briefcase containing stolen military radio equipment from the old depot, the same depot that was torn down from the inside out with reports of infected meat, assumed to be sabotage. Their names are Robert, Sarah, and a younger man named Freddie."

He pauses, his dead eyes locking onto yours with unmistakable seriousness.

"They're dangerous, and they're lying about their cargo. When they reach the front of the line, you are to initiate full inspection immediately. If they refuse to surrender the briefcase or show any sign of hostility, do not attempt to negotiate. Mark them as hostile, call for backup on the radio, and if they advance on the gate, you have authorization to terminate them on sight. Understood? Don't let their 'family' act fool you they're a threat to the colony."

TAKEN HOSTAGE

The afternoon sun hangs low and weak behind a shroud of toxic smog, casting everything in an unhealthy, jaundiced light. Heat radiates off the asphalt in shimmering waves, carrying with it the stagnant stench of unwashed bodies and the iron tang of old blood from the morning's earlier casualties. The generator hums with a tired, mechanical wheeze, a constant drone that has become as background noise as the distant, lonely calls of scavengers in the ruins beyond. Sweat beads on every surface the metal railing, the conveyor belt, the skin of the desperate people shuffling toward you.

After twelve hours of relentless scrutiny, the authority of the checkpoint feels like a performance. Your eyes burn from reading faded ID cards and scanning for the minute tell tale signs of infection: the dilated pupil, the involuntary tremor, the fever flush. The sign behind you remains the only constant in this shifting hellscape, its commands stark and unyielding:

** Mandatory Inspection Rules ** 1. State name & provide ID. 2. Bags on the conveyor belt. 3. Declare all contraband and weapons. 4. Strip completely. 5. Arms out and spin (bite check). 6. Open mouth and stick out tongue (infection check). 7. Open eyes wide (infection check).

The line has been endless. A skeletal man with sunken eyes had been cleared ten minutes ago; a woman with a weeping wound on her calf had been dragged off to quarantine by the Medic, who moved with the numb efficiency of a butcher. The Private on the catwalk above has been unusually quiet, his rifle slung lazily as he stares at nothing, his spirit clearly broken by the endless cycle of judgment and death. The fatigue has settled deep in your bones, a heavy, lethargic weight that makes every movement feel sluggish and every decision feel like a monumental effort.

Then, the rhythm breaks. It doesn't start with a scream or a gunshot, but with a sudden, violent shift in the crowd's desperation. A man in the queue someone who had been compliant and quiet throughout his inspection suddenly lunges forward with terrifying speed. Before you can react, before your fingers can even twitch toward the grip of your MP5, a heavy fist connects with your temple. The world tilts violently; stars explode across your vision as your legs give way.

Pain explodes through your skull as you hit the concrete, but before you can recover, a rough hand tangles in your hair, yanking your head back with brutal force. The cold muzzle of a pistol presses hard against your temple, grinding against your skin. Your MP5 is gone, ripped from your grasp by the assailant who now holds you in a vice like grip, using your body as a shield between himself and the guards above.

"STAY BACK! DON'T YOU FUCKING MOVE!" the man roars, his voice cracking with a manic, desperate rage. His eyes are wild, bloodshot, and fixed on the catwalks.

Chaos erupts down the line as the dam finally breaks. Several other figures men with hardened faces and weapons concealed beneath filthy rags spring from the crowd. They move with tactical precision, not like panicked refugees, but like predators. One grabs a young woman by the throat, dragging her behind him while levelling a shotgun at the nearest guard; another holds a terrified elderly man hostage, using him as a human barrier against the approaching Private. Are they raiders breaking in? Slavers looking for fresh stock? Or something far more sinister? The motives are buried beneath their snarling hostility as the checkpoint transforms from a gateway of salvation into a killing field.

"PUT THE GUNS DOWN OR I PULL THE TRIGGER!" the man holding you screams directly into your ear, his breath hot and reeking of cheap alcohol. You can feel his pulse hammering against your back as the guards on the catwalk raise their rifles, their fingers tightening on their triggers.
