About This Game

OBSESSION — The Vanishing Witness

Three weeks ago, a man fell from Wujiang Bridge. The police ruled it suicide. Case closed.
Three weeks later, five strangers vanish one after another. Their only common thread: that same night, each of them crossed that same bridge.
It wasn't suicide.

The Detective

Lu Yan, 28. Detective with the Criminal Investigation Brigade. Nickname: "Mad Dog" — once he bites into a case, he doesn't let go.
Pressure from above. Witnesses gone silent. The shadow of a corporate empire weighing on every report.
You have 9 days to bring all five back alive.

Gameplay

The Vanishing Witness gives you two things at once.

One. Hours of long-form cinematic video. Surveillance pulls, dashcam recordings, interrogation playbacks, scene reconstructions, character dialogue — everything delivered through the camera. The video isn't a cutscene. It's the evidence you have to study. You watch for the details everyone else missed.

Two. A genuinely punishing evidence board. 130+ clues, 70+ deductions — all dragged, placed, and connected by your own hand. The system doesn't reason for you, and it doesn't filter. Once a clue lands on the board, it stays. Once a red string is drawn, it doesn't come down. When you're truly out of ideas, spend Intuition coins for a hint.

The video lets you see the scene. The board forces you to think it through. The two alternate — and that's the core of this game.
