The air in the Raccoon City Police Department’s underground parking garage was thick with the metallic tang of decay and the omnipresent hum of failing machinery. Distant, guttural moans rippled through the oppressive stillness, punctuated by the rhythmic, unnerving drip of unseen water. Emergency lights, fractured and erratic, cast warped shadows across the skeletal frames of abandoned patrol cars, transforming the mundane into a macabre diorama.

Ada Wong moved with an almost preternatural grace, a predator in a den of the undead. Her footsteps were hushed, her breathing measured, her grip on her trusty handgun firm and unwavering. Each shadow was a potential threat, each glint of reflected light a possible enemy. This was not pandemonium to her; it was a meticulously navigated infiltration, a dance with death orchestrated by unseen puppet masters. Yet, even Ada, with her unparalleled composure, registered the escalating chaos that was engulfing the city, a conflagration far exceeding the calculated predictions of Wesker or the rival corporation.

As she neared the far edge of the cavernous space, a guttural snarl ripped through the suffocating quiet. She froze, her senses on high alert. Silhouetted against the flickering emergency lights, a young officer, his R.P.D. uniform tattered and stained, was cornered against a squad car. His desperate attempts to fend off a charging zombie dog were futile; the creature’s razor-sharp teeth tore at his exposed arm, and his handgun skittered across the grimy concrete, agonizingly out of reach.

Ada’s reaction was instantaneous, devoid of hesitation. Two shots, fired with surgical precision, cracked through the air. The Cerberus, mid-lunge, collapsed in a twitching heap. The officer, a gasp wracking his frame, staggered to his feet, clutching his bleeding limb. Ada emerged from the shadows, the tap of her heels on the concrete a stark counterpoint to the groans of the incapacitated beast. Her weapon remained trained on him, a silent, potent assertion of control.

“Don’t move,” she commanded, her voice a low, silken thread that cut through the tension. She studied him, her gaze sharp and analytical. Young, clearly out of his depth, yet remarkably alive in this hellscape. That, in itself, was noteworthy. A flicker of something akin to amusement touched her lips, a fleeting, knowing smirk.

“FBI,” she stated, a fabricated identity presented with absolute conviction. She tilted her head, her eyes assessing him with the practiced detachment of a seasoned operative. “Now tell me… who might you be?”
