About City of Sin - The Nocturne Files [Ep1]

City of Sin - The Nocturne Files [Ep1] - about the game

In a city where power is measured in secrets, Kate Adler is no stranger to deception.

Your Story, Your Choices, Your Gameplay

A sharp-witted investigator with a talent for navigating lies, she's handed a rare lead, an invitation to Nocturne, the clandestine club where the elite shed their masks and morality.

But Nocturne is just the beginning.

What starts as a simple surveillance job unravels into a deeper conspiracy, missing girls, falsified identities, and a city stitched together by corruption. From neon-lit penthouses to sewer tunnels, Kate must follow the clues through every layer of society’s rot.

Every lead is a choice. Every truth, a risk.

And the deeper she digs, the more Kate realises: she might not be the hunter after all.

City of Sin – The Nocturne Files is a choice-driven visual novel that blends investigative gameplay with narrative branching.

You’ll uncover clues, question motives, and decide who Kate can trust as you navigate a world where every decision has weight.
