The Last Code

Not Human

The Alpha Shattered’s roar shook the bunker passage, its glowing maw tearing through the hatch like paper.

Jace’s ears rang, Lena’s words—“You’re not human”—burning hotter than the blood dripping from his wounds. The Codex’s command screamed in his mind: Eliminate rival Codex-bearer. Warning: Classified data divulged.

His sister stood beside him, her nanite blade raised, eyes conflicted but fierce. Elara braced against the wall, plasma-cutter humming, her face pale from blood loss.

The passage was a choke point, and the Alpha was coming.

“Jace, snap out of it!” Elara yelled, firing a plasma burst. The beam grazed the Alpha’s shoulder, black ichor spraying, but it didn’t slow.

Its claws raked the walls, nanites pulsing in its veins like the Signal Spire’s light. Jace’s Codex flashed: Threat level: Lethal. Survival probability: 8%. Subroutine available: Nanite Grenade. Cost: Critical neural strain.His head throbbed, vision blurring. Host neural integrity: 73%. Lena’s claim clawed at him—not human? Impossible.

But the Codex’s planted memories, the hum rewriting his thoughts, made doubt creep in. “What am I, Lena?” he growled, crafting a nanite grenade as the blueprint burned in his mind.

The air shimmered, forming a pulsing orb in his hand.

“Later!” Lena snapped, dodging the Alpha’s claw. She slashed, her blade carving a gash in its arm, but the creature swatted her like a doll. She hit the wall, gasping, blood seeping from her side. Jace hurled the grenade, the explosion rocking the passage.

Green fire engulfed the Alpha, its screech deafening, but it staggered through, half its face charred.

“Run!” Elara grabbed Jace, pulling him deeper into the passage. Lena stumbled after them, clutching her ribs. The Codex’s timer ticked: 23:36:05. Mission: Survive the Alpha.

The passage sloped downward, toward Bunker-17’s core, but the Alpha’s claws echoed behind, relentless. Jace’s scav-suit was shredded, pain lancing his side, yet the Codex pushed him forward: Nanite Forge Tier 2 available. Craft: Kinetic Spike.

He focused, nanites coalescing into a jagged spear. His nose bled, neural strain hitting like a hammer, but he spun, hurling the spike.

It pierced the Alpha’s chest, pinning it to the wall. The creature thrashed, ichor pooling, and for a moment, Jace thought they’d won. Then its maw glowed brighter, nanites knitting its wounds.

Codex-bearer detected, the Codex warned. Alpha designation: Enhanced.“It’s like us?” Jace gasped, backing away. Lena’s eyes widened, confirming it. The Alpha wasn’t just a monster—it was part of the aliens’ test.

“Keep moving!” Elara shouted, her cutter’s charge flickering. The passage opened into a maintenance bay, rusted pipes and flickering lights casting eerie shadows. A blast door loomed ahead—Bunker-17’s inner sanctum.

Elara hacked the panel, sparks flying. “This is our shot. Hold it off!”

Jace and Lena stood shoulder-to-shoulder, blades ready. The Alpha charged, faster now, its claws a blur. Jace activated Reflex Overclock, time slowing as he dodged, stabbing its flank. Pain seared his skull, blood streaming from his eyes.

Lena’s blade flashed, severing a claw, but the Alpha’s tail whipped, slamming her to the ground. “Jace!” she cried, voice raw.

He dove, shielding her, the Alpha’s claw grazing his back. The Codex screamed: Eliminate rival or be terminated. “Shut up!” Jace roared, stabbing upward.

The Alpha recoiled, but Lena pushed him off, her face twisted with pain and something else—regret?“You don’t get it,” she whispered.

“The Codex made you. You’re their prototype.”Before he could respond, the blast door hissed open. Elara waved them through.

“Now!”

Jace dragged Lena, the Alpha’s roar shaking the bay. They stumbled into a dim corridor, the door slamming shut.

The Alpha’s claws scraped outside, but it held—for now.Jace collapsed, gasping, blood pooling beneath him. Host neural integrity: 70%.

Lena leaned against the wall, clutching her side. Elara checked her wrist-comm, face grim. “We’re in, but the Spire’s signal is spiking. Something’s coming.”

“What am I, Lena?” Jace demanded, voice hoarse. “What’s the Codex hiding?”She met his gaze, eyes haunted. “You were born human. But the signal… it changed you. Before the Collapse. You’re their key.”

The Codex cut in: Warning: Hostile data breach. Terminate rival. A new blueprint flashed—a nanite toxin, lethal to Codex-bearers. Jace’s hand twitched, the urge to craft it overwhelming. He fought it, head splitting.

Not human. The planted memories—Lena’s screams, their past—felt like lies.

Elara stepped between them, cutter raised. “Enough. The Codex wants you two dead. Fight it, or we all die.” Her comm crackled, a distorted voice breaking through: “Kade, you’re activated. The Spire calls.”

Not Lena. Not Bunker-17. Alien.The corridor shook, lights flickering. The Codex’s hum became a scream, and Jace’s vision flashed with a new message: Ascension Key located. Rival Codex-bearer holds fragment.

Lena’s blade glowed brighter, a faint pulse within it. She backed away, eyes wide.“You have it,” Jace realized, stepping closer. “The Key.”

“Stay back!” Lena raised her blade, trembling. The door buckled, the Alpha breaking through, and the Codex roared: Claim the Key or perish.
