The death at Wujiang Bridge was ruled a suicide, but three weeks later, five unrelated witnesses sequentially disappear. Detective Lu Yan has only nine days to uncover the truth and bring them back alive; he must review surveillance, dashcam, and interrogation footage, then connect over 130 clues into more than 70 deductions.
Obsessive Detective — The Vanishing Witness Three weeks ago, a man fell from Wujiang Bridge. The police ruled it a suicide and closed the case. Three weeks later, five ordinary people with no connection to each other went missing one after another. Their only commonality: they all passed by that bridge on that night. It was not a suicide. The protagonist, Lu Yan, is a 28-year-old detective in the Criminal Investigation Division, nicknamed "Mad Dog.exe" for his tenacity—he never lets go of a case once he sinks his teeth into it. Pressure from above, silent witnesses, and the shadow of conglomerates loom over every report. You have only 9 days to bring all five people back alive. Gameplay "The Vanishing Witness" offers you two core elements. First, high-quality, long-form narrative videos. Surveillance footage, dashcam recordings, interrogation replays, crime scene reconstructions, and character dialogues are all presented through cinematic lenses. These videos are not mere cutscenes; they are the evidence you must review. You need to spot details in the footage that others overlook. Second, a truly brain-burning evidence board. With 130+ clues and 70+ deductions, you manually drag, place, and connect them on the board. The system does not reason for you, nor does it filter information. Once a clue is pinned, it remains permanently; once red lines are connected, they never disappear. If you're stuck, you can spend Intuition Coins to get a hint. The videos let you see the scene, while the evidence board forces you to think it through. This interplay forms the core gameplay loop. More Details Four major investigation systems: Video Forensics, Crime Scene Investigation, Evidence Board Deduction, and Mobile Messages. Multiple threads run in parallel, cross-verifying each other. Living People, Not Case Numbers: Each of the five missing individuals has their own profession, family, habits, and last social media post. Your goal is to bring them back alive within 9 days. Choices Have Consequences: How you reply to Shen Ke, whether you confront or cooperate with the team leader, and whether you use gray-channel contacts like Ah Gui will all be remembered and referenced later. Main story lasts 6–8 hours, faster for skilled deductive players. One-time purchase, no microtransactions, no loot boxes, no ads. "Obsessive Detective" Series Wujiang City is coastal, with frequent fog in autumn and winter. Beneath the skyscrapers lies another city—the dark side woven from real estate, finance, and power. Lu Yan will investigate case by case. The old unsolved case haunting him for years hides behind every new investigation. "The Vanishing Witness" is the first case in this series. Perfect for you if: You enjoy narrative-driven deduction games like Ace Attorney, Her Story, Return of the Obra Dinn, and The Dark Pictures Anthology. You're willing to pause and think for five minutes in front of the evidence board rather than waiting for system hints. You don't mind a fair amount of reading. Language: Full Simplified Chinese.
