City of Sin The Nocturne Files Ep1 game, In a city where power is measured in secrets, Kate Adler is no stranger to deception. 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. Your Story, Your Choices, Your Gameplay. 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.
