adjusted the high-frequency transmitter hidden in his cuff, the cold rain of Neo-Berlin slicking his tactical gear. The "CG Update"—the Code-Genetic sequence that could rewrite a human’s neural blueprint—was finally loaded onto a portable drive. He had spent months infiltrating the High-Alpha labs, and now, with the sirens wailing through the sterile corridors, he was the most wanted man on the continent.
He ducked into a narrow alleyway, the neon signs reflecting off the puddles in flashes of electric blue and violent pink. Behind him, the rhythmic thud of mag-boots echoed. The High-Alpha enforcers were closing in. They didn't want the drive back; they wanted him dead so the data would perish with him. 17 checked his internal HUD. The upload progress bar flickered at forty-two percent.
"Hold the line, 17," a voice crackled in his ear. It was Maddy, his handler. "The satellite link is patchy through the storm. You need to stay in the open for three more minutes."
"Staying in the open is a death sentence, Maddy," 17 hissed, pressing his back against a rusting dumpster. He pulled his silenced sidearm, checking the charge. One magazine left.
He broke into a sprint, heading for the central plaza. The enforcers opened fire, red plasma bolts searing the air around him. He dove behind a fountain, the CG Update ticking up to sixty percent. The data was heavy, a digital labyrinth of genomes and encryption keys. If he succeeded, the world’s elite would lose their monopoly on biological perfection.
"Eighty percent," Maddy whispered, her voice tight with tension.
17 rose from cover, returning fire with surgical precision. Two enforcers went down, their armor sparking. But more were coming, a tide of black chrome and lethal intent. He felt a sharp sting in his shoulder—a grazing shot. He didn't flinch. He couldn't afford to.
He reached the highest point of the plaza, a glass overlook peering into the abyss of the lower city. He held the drive high, the signal strengthening as the clouds parted for a fleeting second. "Ninety-eight... ninety-nine..." The progress bar turned green. Upload Complete.
17 didn't wait for the enforcers to reach him. He looked at the drive, now a useless piece of plastic, and tossed it into the dark void below. With a smirk that never reached his eyes, he triggered his thermal cloak and vanished into the rain, leaving the High-Alpha guards chasing a ghost. The world was about to change, and Agent 17 was already moving on to his next target.
