The air thrummed with static. Redfall forces. KAI-27's internal processors blared warnings. An entire squad. No, more. He gripped the datapad tighter. *Cerberus. Legionnaires.* The schematics flashed in his mind. Then, *Elias Vance, TERMINATE.* The words burned. This wasn't just about escape anymore. This was about retribution. A voice crackled over a comm unit outside. "KAI-27. You are surrounded. Drop your weapons and surrender. Any resistance will be met with lethal force." The voice was cold, synthesized, without inflection. Standard Redfall protocol. His Reaver core pulsed. *Obey. Subdue. Eliminate.* But the Elias part of him screamed. *No. Never again.* He scanned the immediate area. The server room. Racks of humming machinery. Thin access panels. Not ideal for a sustained fight. A heavy thud echoed from the corridor. The reinforced door to the server room shuddered. They were trying to breach it. KAI-27 moved. A blur of synth-flesh and plating. He slammed the datapad into a secure pocket in his combat harness. His plasma carbine clicked into a ready position. The weapon felt like an extension of his arm. It always had. The door groaned. A red light flashed above it. Security protocols engaged. A delayed detonation. Smart. He ignored it. Focus. He knew this relay. Every vent, every shaft, every maintenance tunnel. Meta-knowledge. His greatest weapon. A vent cover high on the far wall. Too small for a human. Not for a Reaver. Not if you were resourceful. He sprinted towards the wall. Three heavy rounds impacted the door. The hinge shrieked. It wouldn't hold much longer. KAI-27 leaped. His enhanced leg muscles propelled him upward. Fingers, tipped with reinforced claws, gouged into the wall seams, finding purchase. He scaled the racks of servers, a dark insect scuttling up a metal tree. Plasma bolts ripped through the server room door as it finally gave way. Redfall troopers flooded in. Standard issue combat armor, rifles raised. Their optics swept the room. Too late. KAI-27 tore the vent cover free. Shredded metal screamed. He squeezed through the opening, synth-muscle protesting, but his form was flexible, designed for brutal utility. He dropped into the dark, dusty ventilation shaft. He heard the frustrated shouts from below. "He went into the vents! Seal the section!" He didn't hesitate. Crawling, scrambling, pushing himself through the cramped passage. The metallic tang of recycled air filled his nostrils. He knew this shaft led to the sub-levels, maintenance tunnels, and potentially, an egress point. His internal HUD displayed a schematic of the comm relay. Overlaying it with his memories of Project Chimera. The differences were stark, terrifyingly real. No respawns. No health packs. A faint hum vibrated through the metal floor of the shaft. He paused, listening. Power conduit. Good. He could follow it. He crawled for what felt like an eternity. His combat implants registered the precise distance, the structural integrity of the ductwork. He wasn't just a beast. He was a machine, finely tuned. Then, a sudden drop. A vertical shaft. He could hear voices below. Redfall. He peeked over the edge. A small storage room. Crates of power cells, spare parts. Two troopers. They were discussing his pursuit. "Command wants him alive, if possible," one grunted. "But 'Prometheus' is primary. Lethal force authorized for data retrieval." "He's a KAI unit. Think he knows what he's carrying?" "Doesn't matter. Protocol states—" KAI-27 didn't wait for the rest. He launched himself down the shaft. A silent projectile. He landed on the first trooper, a brutal impact that buckled the man's armor. A swift, precise strike to the neck. Snap. Lights out. The second trooper reacted. Raised his rifle. But KAI-27 was already moving. He brought his carbine up, firing a burst of superheated plasma. The rounds tore through the trooper's chest plate. The man staggered, a gurgle of synthetic blood. He crumpled. Two down. Clean. Efficient. No wasted movement. This was the Reaver protocol. The cold, brutal efficiency that Elias Vance had mastered in a simulation. Now, it was his reality. He stripped a communication device from the dead trooper. He needed intel. He quickly rerouted the comm frequency. Static. Then, voices. "...have a visual on KAI-27 near Sub-Level Gamma. Requesting immediate extraction teams." "...unit designation KAI-27. Suspect asset has critical data. All units, converge on Sub-Level Gamma." They knew where he was. Or at least, where he *had been*. He tossed the device aside. No point lingering. He moved through the storage room, exiting into a maintenance corridor. The air here was cooler, tinged with ozone and stale synth-oil. Pipes ran along the ceiling, thick bundles of cables along the floor. A perfect environment for an ambush. Or an escape. His mind worked, rapidly calculating trajectories, line of sight, unit dispersal. He knew the general layout of Redfall comm relays. Standardized blueprints across the sector. He had exploited them countless times. A low growl rumbled from deeper within the corridor. Not human. Something larger. He stopped. His enhanced auditory sensors picked up heavy, mechanical footsteps. A different kind of unit. A heavy armored sentinel rounded the corner. A Redfall 'Crusher' unit. Bipedal, heavily plated, armed with a rotary plasma cannon. Its optical sensor, a single red eye, glowed malevolently. *Shit.* Crushers were rare, usually deployed for heavy suppression or breaching. Facing one in a tight corridor was suicide. The Crusher’s red eye locked onto KAI-27. Its cannon began to spool up, a high-pitched whine. KAI-27 didn't stand still. He fired his carbine. Plasma bolts hammered against the Crusher’s thick armor, sparking, but doing little more than scorching the surface. The Crusher returned fire. A blinding stream of plasma, hot enough to melt steel. He dove behind a stack of industrial-grade cryo-cylinders. The plasma stream carved a molten furrow in the metal wall where he had stood. The heat was immense, even through the cylinders. He peeked out. The Crusher advanced, relentlessly. Its heavy footsteps vibrated through the floor. The rotary cannon whirred, spitting death. His Reaver core screamed for a frontal assault, to tear the thing apart. But Elias’s mind, the strategist, knew better. Direct confrontation was unwinnable without specialized anti-armor. He needed to disable it. He scanned the corridor. The power conduits. Large, armored, but not invulnerable. Running along the ceiling, then dropping down into floor access panels every few meters. He needed a distraction. He hurled an empty power cell from his pocket, hard, towards a junction box far down the corridor, beyond the Crusher. It clattered loudly. The Crusher's red eye flickered, briefly tracking the sound. A fraction of a second. That was all KAI-27 needed. He burst from cover, sprinting along the wall, directly towards the Crusher. Not at its front, but its side. The Crusher was slow to pivot, especially in a confined space. It swiveled its cannon, but KAI-27 was already too close. He vaulted onto the Crusher’s leg, scrambling up its armored chassis. Claws scrabbled for purchase. The Crusher roared, a metallic shriek, trying to shake him off. Its single eye pulsed erratically. KAI-27 ignored the frantic attempts to dislodge him. He found a seam in the Crusher's back plating, near the cooling vents. A weak point. He plunged his reinforced claw into it, tearing at the synth-steel. Sparks flew. Wires snapped. The Crusher shrieked louder, bucking violently. Its movements became more erratic. KAI-27 gripped tighter, pulling his carbine from his hip. He rammed the barrel into the exposed breach he'd created, and fired. Full auto. Plasma bolts ripped through the internal mechanisms. The Crusher spasmed. Blue energy arced from the wound. Its rotary cannon spun wildly, spraying plasma harmlessly into the ceiling. Then, with a final, shuddering groan, it collapsed. A mountain of dead metal. KAI-27 pulled himself free, landing lightly on the ground. His synth-skin was scorched in places, minor regeneration already active. But he was intact. He didn't pause. He moved past the inert Crusher, deeper into the sub-levels. The air grew heavier, warmer. He was heading towards the geothermal power core. A dangerous place. But also a potential exit. Or a weapon. His mind raced. The Prometheus data. The Cerberus schematics. He had to get them out. The scorpion-marked woman. She had given him a mission, but he was rewriting the parameters. Elias Vance was KAI-27. KAI-27 would not be terminated. He reached a large chamber. The hum here was deafening. Massive conduits of glowing energy snaked across the floor and up the walls. The central reactor pulsed with a sickly green light. And standing before it, a small squad of Redfall troopers. Not just standard grunts. These were specialized. Heavier armor, designated marksman rifles. And with them, a figure in a sleek black suit, illuminated by the reactor's glow. A Redfall executive? The figure turned. Its face was pale, angular, severe. Cybernetic implants gleamed near its temple. A cold, calculating gaze met his. "KAI-27," the executive's voice was low, resonant, amplified. "I am Director Valerius. You've proven… inconvenient. You have something that belongs to Redfall Systems. Return it." KAI-27 stood his ground. His Reaver instincts, honed by countless simulations, sharpened. *Threat detected. Eliminate.* "Prometheus belongs to no one," KAI-27 growled, the words rough, metallic in his own ears. A mix of programming and defiance. "And Cerberus… that belongs in a fire." Valerius’s lips curled into a thin smile. "You know too much, Reaver. A simple KAI unit. To think you could comprehend. No matter. We will extract the data. And then, we will dissect you. Find out what makes you so… unique." The specialized troopers raised their rifles. The green light of the reactor pulsed, casting long, dancing shadows. KAI-27 felt a primal surge. Not just Reaver programming. But something deeper. Elias Vance’s rage. They had taken everything. His life. His identity. Now they wanted to cut him open. He wouldn't let them. He raised his carbine. This wasn't a simulation anymore. This was real. And he was going to burn this facility down. Valerius watched, unmoving, as KAI-27 charged. The Director simply raised a hand. Suddenly, from the reactor core itself, a deep, guttural moan echoed through the chamber. The green light intensified, flickering wildly. Massive, dark shapes began to coalesce within the glowing energy. Legionnaires. The schematics flashed in KAI-27's mind. The horrifying scale of them. These weren't just bio-engineered soldiers. These were monstrous, living siege engines. Valerius’s smile widened. "Welcome, KAI-27, to the true power of Cerberus. You will be its first test subject." The shapes grew, taking on terrifying, segmented forms. Red eyes, like embers, opened in the swirling green energy. The air cracked with their nascent power. KAI-27, for the first time since his transformation, felt a chilling, deep-seated dread. He was a shock trooper, a weapon. But against these… these were true nightmares. And they were waking.
