The tunnel was claustrophobic; the walls closing in around them as they sprinted toward the narrow passage that would lead them back to the surface. Every step was a heavy echo in the darkness, their breaths ragged as they pushed forward. The distant sounds of bio-mutants’ claws scraping across the floor were growing louder, but Andy forced them to move faster. He could feel the cold sweat dripping down his spine, his heart hammering in his chest.

  "Almost there, just a little farther!" Andy urged, his voice barely more than a strained whisper.

  Suddenly, there was a low, growling sound from behind them. The ground beneath their feet trembled. The hairs on the back of Andy’s neck stood on end.

  "What the hell is that?" Jorin panted, his voice full of panic.

  Before anyone could respond, the shadows at the tunnel’s edge seemed to writhe, and a massive form emerged. A bio-mutant, larger than any of them by at least twice, its body a grotesque mass of flesh and mechanical parts fused together. Its eyes glowed an eerie yellow as it let out a deafening screech, shaking the tunnel.

  The creature was like nothing Andy had ever seen. It was a towering, hulking mass of sharpened limbs and rusted metal, its metal limbs clinking as it stalked forward. A jagged, rusted blade extended from one arm, its other hand more like a claw—designed to shred, to tear, to maim.

  "Shit!" Andy yelled, raising his energy pistol instinctively. He fired a blast at the creature’s chest, but it barely flinched. The plasma blast only sizzled against its armored hide, leaving a small scorch mark.

  The creature roared, its eyes narrowing, focusing entirely on the group. It lunged forward with terrifying speed, closing the distance in an instant, its claw swiping through the air with lethal intent.

  "Get down!" Andy screamed, tackling Tobin out of the way as the bio-mutant’s claw whistled inches above their heads. The creature’s swipe left deep gouges in the tunnel walls, sparks flying from the stone as metal scraped against stone.

  The recruits scattered, moving in all directions, scrambling for cover.

  "Move!" Andy shouted, firing again, this time aiming for the creature’s head. The shot struck true, but again, the impact was minimal. The bio-mutant didn’t even seem to register the hit. It was an unstoppable force of nature, a terrifying blend of biology and machine.

  Tobin, still struggling to stay conscious, grabbed his weapon and tried to fire, but his shots were wild, missing entirely.

  "Jorin, get Tobin out of here!" Andy barked, his voice tight with urgency. "I’ll hold it off!"

  Terror froze Jorin as he stared at the creature, his eyes wide. "I can’t—"

  "Now!" Andy roared, pushing him toward Tobin. "You two move! I’ve got this!"

  Jorin hesitated, but the urgency in Andy’s voice made him snap to action. He grabbed Tobin’s arm, pulling him toward the narrow passage ahead, leaving Andy standing alone against the towering monstrosity.

  The bio-mutant concentrated entirely on Andy, its glowing yellow eyes narrowing on him. It was like a beast sensing its prey, instinctively drawn to him.

  Andy’s heart raced. He needed to keep it distracted, keep it from following the others.

  Thinking quickly, he ducked into a side passage, hoping the creature would follow. It did. The bio-mutant let out a shrill, almost mechanical screech as it charged after him, its massive footsteps shaking the ground beneath him.

  Andy barely had time to react. He turned, firing off a few more shots at the creature’s exposed joints, hoping to disable it. The shots hit with a satisfying crack, but the creature barely slowed down. Instead, it swung its enormous arm at Andy, sending him crashing into the wall.

  Pain shot through Andy’s ribs as he hit the stone, but he didn’t have time to dwell on it. He scrambled to his feet just as the creature lunged again, its claws tearing through the air. Andy dove to the side, narrowly avoiding the attack, but the sheer force of the bio-mutant’s swipe sent another shudder through the tunnel.

  "Come on, think!" Andy muttered to himself. His mind raced, trying to find something, anything, that could stop the beast.

  He caught sight of a large industrial pipe running along the ceiling. If he could break it open, maybe he could use the water pressure to throw the creature off balance. It was a long shot, but right now, he had nothing else.

  "Here goes nothing," he muttered under his breath as he sprinted toward the pipe.

  He reached up, gripping the loose bolts and yanking them free with one hard pull. Water surged from the broken pipe, spraying in a torrent and hitting the bio-mutant square in the face. The creature howled in fury, momentarily distracted by the flood of water, its body twitching as the pressurized liquid forced it backward.

  Andy didn’t hesitate. He grabbed a nearby rock, hefted it with all his strength, and threw it into the bio-mutant’s glowing eyes. Roaring in complete rage, the creature’s vision was impaired, its head snapping wildly from side to side.

  Taken from Royal Road, this narrative should be reported if found on Amazon.

  "Now!" Andy shouted, charging at it from behind. With all the strength he could muster, he plunged his energy pistol deep into the back of the bio-mutant’s neck and fired. Sparks flew as the energy bolt ripped into the creature’s mechanical components, and with a deafening screech, the mutant shuddered violently.

  For a moment, it seemed like it might fall, but then the creature twisted around, its claw swiping at Andy, missing him by inches.

  Andy stumbled back, his heart in his throat, and watched in disbelief as the bio-mutant’s limbs jerked and spasmed. Then, with a final, painful cry, the creature collapsed, its massive body crumpling to the ground in a heap of twisted metal and blood.

  Andy stood there, gasping for breath, sweat dripping from his forehead. He was alive. The bio-mutant was down.

  But the fight wasn’t over. Not yet.

  He quickly turned to make sure the others were safe. They were just ahead, Jorin supporting Tobin, both of them panting heavily.

  "Andy!" Jorin yelled. "Are you okay?"

  Andy nodded, his chest still heaving with adrenaline. "Let’s move. We’re not out of this yet."

  And with that, they pushed forward, knowing they had narrowly escaped the jaws of death—at least for now.

  The group moved quickly through the Catacombs, the weight of their recent encounter hanging over them like a thick fog. The air was dense with the scent of rust and decay, every step echoing in the narrow, claustrophobic tunnels. Andy’s thoughts raced from the fight, the adrenaline ebbing but leaving a simmering resolve in its wake. The creature had been created in the aftermath of the fall of civilization, designed for war but now reduced to stalking the ruins of the Catacombs and the wasteland. They were nightmares, remnants of a world gone wrong, hungry for any living thing that ventured too close. They were bigger and meaner then he could have imagined.

  Andy tightened his grip on the energy pistol, his knuckles whitening as he scanned the dimly lit passage ahead. His heart still thundered, not from fear, but from something more primal. The bio-mutant’s attack had awakened a part of him he barely understood—an instinct buried under years of survival and ingenuity. It wasn’t just the desire to live. It was the urge to fight, to overcome, to conquer something that should have been stronger than him.

  A fire burned in his chest, hot and unyielding. The will to prevail coursed through his veins, sharper than the fear that had gripped him only moments before. Andy cursed under his breath, jaw tightening. Losing wasn’t an option—not to the bio-mutants, not to the darkness pressing in around them, and not to whatever unseen forces waited deeper in the Catacombs.

  “We’ll find a way out,” Andy said, his voice cutting through the oppressive silence. It was sharper now, laced with a confidence that felt both foreign and familiar. “Just keep moving.”

  The group pushed forward, Andy setting the pace with determined strides. The Catacombs seemed endless, the labyrinthine passages stretching into shadowy uncertainty. Despite his past explorations, he’d never ventured this deep, and the weight of the unknown bore down on him like the thick, stale air. Every corner they turned, every new hallway they ventured into, carried the promise of danger.

  Yet Andy didn’t falter. Each step felt like a challenge, a test of his resolve. The oppressive sense of being watched clung to them, but instead of shrinking from it, Andy felt himself bristle, the fire in his chest growing brighter. He wasn’t just surviving anymore. He was pushing back, refusing to let the darkness win.

  “Stay close,” he said over his shoulder, his voice steady, commanding. “And don’t stop for anything.”

  The others followed without hesitation, their own fear tempered by the sheer force of Andy’s determination. The Catacombs stretched on, vast and unknowable, but Andy’s focus never wavered. The shadows might have been watching, but Andy was ready for them. Whatever was waiting ahead, he would face it—and he would win.

  They’d barely made it past another intersection when a loud, mechanical clank echoed through the tunnel, followed by the unmistakable screech of more bio-mutants.

  "Shit," Andy muttered under his breath.

  "How many?" Jorin asked, his voice tight.

  "I don’t know," Andy said, his eyes scanning the shadows. "But we can’t wait to find out. Keep moving, all of you. I’ll cover the rear."

  The others nodded, and Andy dropped to the back of the group, his energy pistol at the ready. His heart pounded in his chest, adrenaline spiking once again. He had done this before, faced down danger in the shadows, but this was different. This time, it wasn’t just him. He had to keep everyone alive.

  The noise grew louder, and then, through the dim glow of their flashlights, Andy saw them—more bio-mutants, this time smaller but faster, their limbs clicking and shifting as they raced toward the group. They moved in a blur of metal and flesh, their bodies glued together by whatever sick science had created them.

  Andy opened fire first, hitting the closest one square in the chest. The energy shot tore through the creature’s mechanical exoskeleton, sending sparks flying. It staggered, but didn’t fall. Instead, it lunged forward with an inhuman screech, its claws slashing at Andy. He rolled to the side, narrowly avoiding the swipe, and fired again, hitting the thing in the head. The creature crumpled, lifeless.

  "Go! Go!" Andy shouted, urgency creeping into his voice.

  The rest of the recruits were already ahead, moving faster now, pushing past the attack. But Andy kept his focus, firing as the bio-mutants surged forward, more of them appearing from the shadows. This time, there were too many. Andy fired again and again, but the creatures kept coming, their mechanical limbs moving with terrifying precision.

  "Andy!" Jorin called, his voice laced with panic. "We can’t keep fighting them off! We need to get out of here!"

  "We’re close," Andy grunted. He could feel the sweat pouring down his back as he squeezed the trigger again. He was running out of ammunition. He needed to decide—fast.

  He glanced at the others. They needed a way out, and fast.

  "Down that way!" Andy shouted, pointing to a narrow passage that split off from the main corridor. "Head for that tunnel!"

  Without waiting for confirmation, he turned and charged down the tunnel, his footsteps echoing in the silence as the others followed closely behind. The bio-mutants were still coming, but Andy pushed them to move faster, urging them forward with every ounce of energy he had left.

  The passage was narrow, winding, and dark, the walls closing in around them as they hurried through it. The sound of the bio-mutants’ clicking claws echoed behind them, but for the moment, they were gaining ground.

  He had been here before. He had survived this place before.

  "Stay focused," he muttered under his breath, his voice steady despite the chaos. "We’re almost there."

  They ran for what felt like an eternity, the sound of the bio-mutants fading as the tunnel opened into a wider chamber. For a moment, it seemed like they were free.

  But then, the ground beneath them trembled, and the walls of the tunnel seemed to close in. The rumble was unmistakable—the sound of something bigger, something far worse than they had encountered before.

  "Keep moving!" Andy shouted, heart pounding.

  They were almost at the exit. Almost there.

  But would they make it out alive? That was a question Andy wasn’t sure he wanted to answer.

  Enjoy the new chapter! We’re continuing the rite of passage—and finally getting a deeper look at something that’s been quietly building for over a month now.
