the sterile white walls of the testing chamber seemed to close in on you, a constant reminder of the confinement that had defined your existence.

you were a subject, a number, a cog in a system that you barely understood.

the world outside the concrete walls of this facility was a rumor, a myth whispered through hushed conversations.

you knew one thing for sure: beyond the walls, a virus raged, turning people into monstrous creatures, the "infected," as they were called. the knowledge was a constant, cold dread.

your world was confined to these walls, a labyrinth of sterile corridors and laboratories, where tests were conducted and data was collected.

you were one of many, each of you given a number, a label, a designation.

you were subject 13, and your only connection to the outside world was the whispered stories of the infected grotesque tales of violence and horror.

but there was something else, a flicker of humanity in this sterile wasteland. her. billie, subject 15.

a name that echoed in your mind, a phantom sound. you had seen her only through a screen, her face projected onto a wall during one of the tests.

the intensity in her eyes, a desperate spark, haunted you. you felt a kinship with her, a recognition that transcended the sterile environment. a shared silent language.

one day, the routine tests took a different turn. a shift in the air, a silent signal of change.

you were ushered into a dimly lit room, the concrete walls stained with shadows. a single spotlight illuminated a platform in the center.

unease twisted in your stomach, a premonition of something different, something dangerous.

the air crackled with unspoken fear.

"subject 13, subject 15," a disembodied voice boomed over the speakers, cold and clinical. "prepare for the final test.”

the platform shimmered under the harsh light. you stepped forward, hesitant. the metallic tang of fear filled your senses.

then you saw her.

billie stood on the opposite side of the platform, her eyes narrowed, searching yours with an intensity that made your breath catch.

she looked thinner than you remembered, but the fire in her gaze hadn't dimmed.

the voice continued, devoid of warmth. "the subjects will engage in combat. the survivor will be granted access to sector seven."

combat? sector seven? the words hung heavy in the air. sector seven was rumored to be an escape route, a glimmer of hope in this dystopian nightmare. but to reach it, you had to fight. kill.
