About This Demo

Game Description

You will go undercover as a security guard to infiltrate the Jinxiu Apartment complex, which is slated for demolition. The building is shrouded in the shadow of serial murders: a female author's bizarre hanging, an editor's mysterious drowning, a security guard's accidental fall, and a resident's brutal stabbing. All the while, the killer, calling himself "Frogman," openly boasts about his crimes online...

Your true identity is a journalist seeking the truth. By day, you must handle the residents' daily needs to maintain your cover; by night, you must meticulously watch the building's surveillance monitors—covering the lobby, elevators, rooftop, parking garage, and more. Use the unique "Frame-level Investigation" system to capture every clue and piece together the full picture of the events.

Probing online, reviewing footage, searching the web—every step may bring you closer to the truth, but you must remain vigilant. As the warning circulating among the residents says: "That serial killer... they say he never left the building."
