Chapter 2: The Tutorial Beneath the Floor

The hallway outside Eli’s apartment had gone too quiet.

A few minutes ago it had been full of wet shrieks, pounding feet, the raw and human sound of people discovering that doors were not enough anymore. Now the corridor held its breath. The emergency lights that had come on after the power failure painted everything in a rust-red smear—the peeling beige walls, the old water stains on the ceiling, the blood dragged in streaks toward the stairwell.

Eli stood with one hand on his apartment handle and the other wrapped around the length of steel he had ripped from the busted bedframe. It wasn’t much of a weapon. It was too light at one end and bent near the middle. But it was metal, and metal was better than empty hands.

His breathing sounded loud. Too loud.

Below the pounding of his pulse, he heard it again.

Not from the hall. Not from the stairs. From under the floor.

A thin electronic chime, bright and cheerful in the dark, like a machine at the arcade registering a coin drop.

He froze.

Every instinct told him to ignore it. Find Nora. Barricade a room. Survive one hour, then one more. The practical part of his mind—the part that had spent years keeping dying cabinets alive with zip ties, solder, and profanity—told him something else.

Errors did not repeat without reason.

The broken tutorial prompt still hovered in the corner of his vision, its blue text flickering like a cheap sign with failing wiring.

Down.

He looked at the stained carpet beneath his shoes.

“That’s not ominous at all,” he muttered.

His own voice steadied him more than silence did. He crouched and pressed his palm to the floor. The carpet was damp and cold. For a second he felt nothing. Then the boards beneath his hand gave a tiny shiver, as if an elevator were passing through the building where no elevator shaft existed.

A blue seam ignited along the edge of the hall runner.

Eli jerked back. The carpet split from wall to wall without tearing. Space simply unzipped. A rectangle of darkness opened in the middle of the corridor, and a metal ladder unfolded upward from nowhere with a clank that was too solid to be a hallucination.

Cold air breathed out of the gap, carrying scents that did not belong in his building—ozone, damp stone, old grease, and the sweet burned smell of overheated circuits.

The prompt pulsed.

Tutorial access degrading.
Enter now? Y/N

“I hate this,” Eli said, and climbed down.

The opening swallowed the hallway above him after the third rung. Red emergency light snapped away. Darkness sealed over his head, followed by a cascade of blue glyphs that flowed across the walls around him like projected code. The metal ladder trembled under his weight. It went deeper than it had any right to. Ten feet. Twenty. Thirty.

The sound reached him before the bottom did.

Not dungeon ambience. Not the howling fantasy nonsense his sleep-starved brain had expected. It was mechanical and familiar: the distant tick of relays, a low electrical hum, the intermittent jangle of corrupted speakers.

He landed on concrete.

For a moment he just stared.

The sublevel looked as though his apartment building had shed a second skin beneath itself—a secret basement stitched together from pieces of maintenance tunnels, boiler rooms, unfinished parking decks, and the back guts of an arcade. Exposed pipes ran overhead beside bundles of luminous blue wire. Vending machines stood half-buried in cinderblock walls, their glass fronts black and mirrorlike. Ticket dispensers jutted from concrete pillars. Far down the corridor, an EXIT sign buzzed in pink instead of red.

The floor glistened. Not with water. With scrolling code that moved under the concrete surface like fish under ice.

Eli swallowed.

“Okay,” he whispered. “Definitely not supposed to exist.”

A new screen unfolded before him.

Corrupted Tutorial: Foundation Breach
Objective 1: Reach the Anchor Node
Objective 2: Survive
Recommended Level: N/A
Warning: Standard System protections unavailable.
Warning: Loot corruption probability high.
Warning: Causality bleed detected.

At the bottom, a final line appeared one letter at a time, as if something were typing in a hurry.

Use what works, not what’s intended.

Eli barked a humorless laugh. “Now that sounds like my kind of game.”

He moved.

He did not charge heroically into the blue-lit dark. He edged down the corridor with his shoulders tight and his weapon held high, putting each foot down carefully. His work shoes squeaked on the shimmering concrete. Every shadow looked occupied. Every blinking light looked like an eye about to open.

He passed an old prize claw machine embedded halfway into a wall. Plush toys hung inside it, except they were wrong. Their button eyes tracked him. One had too many limbs. Another had a zipper where its mouth should be, tugging itself wider and wider with invisible hands.

He kept walking.

A movement flashed in the reflection of a dead vending machine.

Eli pivoted just as something dropped from the ceiling.

It hit the floor in a skid of glass and chitin. For one impossible instant it looked like a maintenance drone the size of a dog, all camera lenses and thin mechanical limbs. Then its shape glitched. Pixels tore off its body. Its outer shell became translucent, revealing a slick knot of flesh threaded through machinery. A human hand pressed from inside the casing and vanished.

Corrupted Janitor Whelp Lv. 3

The thing screamed through a burst speaker and came for him.

Eli jumped backward. The whelp’s forelimb sliced through the air where his throat had been and struck sparks off the wall. Fast. Way too fast. He jabbed with the steel bar, hit shell, and the impact rattled all the way up his arm. The creature recoiled with a spray of blue static and dark fluid that smelled like antifreeze and rotten meat.

It leaped again.

He barely got the bar across his body in time. The hit drove him into a pillar. Pain flared in his shoulder. The thing clung to the rod, six limbs scrabbling, its head splitting open into a nest of whirring grinder teeth.

“Nope!”

Eli slammed the bent end of the bar into the nearby ticket dispenser out of pure desperation.

The old machine burst to life with a cheerful melody. Tickets vomited from the slot in a papery flood. The whelp’s body jerked. Its lens-eyes snapped toward the movement. For one absurd second it forgot him entirely and pounced on the stream of tickets, shredding them with frenzied mechanical bites.

Eli stared, then saw the pattern instantly.

Arcade conditioning. Target motion. Reward fixation.

Like a bad cabinet AI coded to chase flashing stimuli.

You stupid glitched little raccoon.

He grabbed the dead vending machine beside him, planted his foot against the base, and shoved with everything he had.

The machine tipped with agonizing slowness, then crashed sideways onto the whelp. Glass exploded. Metal folded. The thing shrieked, trapped under several hundred pounds of obsolete sugar delivery system.

Eli did not hesitate. He raised the steel bar and hammered it down into the writhing gap where shell had split. Once. Twice. A third time, wet and ugly. The screech cut off.

Silence rushed back in, broken only by the machine’s tinny victory jingle still trying to play through a ruined speaker.

Eli bent over, breathing hard, his whole body shaking with adrenaline.

A blue pulse rolled out from the corpse.

Enemy defeated.
Experience gained: 12

The body did not dissolve cleanly the way game monsters were supposed to. It collapsed inward in layers, machine parts clipping through flesh, flesh through machine, until only a lump of black crystal remained amid the broken glass.

Another notification appeared, this one bordered in jagged red.

Corrupted Loot Detected.
Item integrity compromised.
Absorption/adaptation chance increased due to class trait: Null Diver

Eli crouched beside the crystal. Up close, it looked less like stone and more like frozen television static. Light crawled inside it. He reached toward it, then stopped inches away.

“Adaptation chance,” he said softly. “And what’s the other chance?”

No answer, of course. He touched it with the tip of the steel bar first.

The crystal burst like a soap bubble. A spray of blue symbols spun around his hand and condensed into an object: a keycard attached to a strip of blood-flecked yellow tickets.

Obtained: Prize Counter Access Tag (Corrupted)
Effect: Opens sealed tutorial doors.
Bonus Effect: +15% movement speed for 8 seconds after passing through a threshold.
Side Effect: Each door crossed may randomize local enemy aggro.
Durability: ???

Eli blinked at the item hanging from his fingers.

“That is the dumbest thing I’ve ever seen.”

The tag flickered and turned semi-transparent, then solid again. When he clipped it to his belt loop, a cold tingle ran up his side like a live wire brushing skin.

He looked at the crushed whelp, the broken dispenser still spilling tickets, and felt the first hard click of understanding settle into place.

Corrupted enemies were dangerous.

Corrupted loot was insane.

And somewhere ahead, if this tutorial was worth the name, there would be worse things guarding better prizes.

He pushed onward.

The corridors twisted in ways the building’s foundation could not possibly support. Once he opened a steel fire door and stepped into a room that should have been a laundry space. Instead it held three rows of arcade racing cabinets, all running the same track. On every screen, a low-resolution city burned under a blue sky. Tiny cars drove themselves in circles. When Eli entered, each pixel driver turned to look directly out of the screens at him.

He backed out and shut the door very carefully.

Another corridor took him through a boiler room where the boilers had been replaced by stacked aquarium glass. Shapes drifted behind the algae-stained panes. Human-sized, too many-jointed. He kept his eyes down and his pace steady.

A sound rose ahead: clack-clack-clack, like marbles bouncing down metal steps.

Eli ducked behind a pillar just as three things scuttled around the corner. They resembled children’s ride-on animals from a grocery store entrance—bright plastic horses mounted on coin-operated bases—except their painted faces had peeled open to reveal probing tongues of cable and teeth. Their metal bases had grown spider legs. Blue saddle lights flashed in hypnotic rhythm.

Carousel Biters Lv. 4 x3

They moved in a loose pack, circling one another, bumping their plastic heads together with eager little chirps.

Eli assessed the corridor in one sweep. Narrow. Exposed pipe overhead. Puddle of something reflective near the wall—oil, maybe. On the opposite side, a fuse box with its panel hanging open, wiring exposed.

Use what works.

He pulled the bent steel bar free, took a breath, and hurled it down the hall.

The bar clanged off the floor. All three Biters snapped toward it at once and launched after the noise with horrifying speed.

Eli sprinted from cover, slammed his shoulder into the fuse box, and ripped free the thickest cable he could grab. Sparks snapped against his hand. He hissed and nearly dropped it. The oil puddle gleamed only six feet away.

The lead Biter pounced on the steel bar and started gnawing it with a shrill plastic laugh.

The other two piled on.

Eli whipped the cable into the puddle.

For a heartbeat, nothing happened.

Then the floor flashed white-blue.

The shock cracked through the corridor with a brutal pop. The puddle erupted into a net of crawling electricity. The Biters spasmed as one, legs locking, saddle lights exploding into showers of sparks. Burnt plastic and charred meat stung the air. One of the things tried to scream and emitted a distorted carnival melody instead.

Eli yanked the cable back and stumbled away. His palm was blistered where current had kissed it. He ignored the pain, grabbed the steel bar from the twitching pile, and caved in what remained of the nearest mount’s face. Then the next. Then the third, until the corridor was silent but for the drip of melting plastic.

Blue text rolled over his vision.

Enemies defeated.
Experience gained: 39
Level increased: 2

Warmth surged through his limbs. Not healing exactly, but correction—fatigue peeling back, breath deepening, his senses snapping into tighter focus. The ache in his bruised shoulder dulled. A second prompt arrived.

Attribute points available: 3

Eli stared at it while smoke drifted around him.

“Right. Stats. Of course stats are real now.”

A transparent panel unfolded. Strength. Agility. Vitality. Perception. Will.

He thought of those first two fights: how close he’d been to getting his throat ripped out, how the only reason he was alive was because the monsters were stupid in specific, exploitable ways. He was not winning on muscle. He was winning on timing.

He put two points into Agility and one into Perception.

The world sharpened. Not dramatically, not superhero nonsense—but enough. The edges of motion became cleaner. He could hear the faint buzz of a faulty light twenty yards away. His own body seemed to respond half a beat faster to what he wanted from it.

The dead Biters left loot too.

One produced a cracked plastic token warm as a tongue.

Obtained: Continue? Token (Corrupted)
Effect: Negate one fatal strike within 10 minutes.
Side Effect: User is forcibly moved to the start of current encounter area.
Warning: Start point may be unsafe.

“That’s… horrifyingly useful.”

He pocketed it.

The second yielded a buzzing coil of copper wire that bit his skin whenever he touched it. The third dissolved into nothing but static and a brief image of a smiling child on the horse ride, gone before he could process it.
