Murder Jump

Greyglass keeps its secrets above street level.

Play as Pip, a rooftop detective following impossible routes through elevators, stations, galleries, radio towers, motels, clinics, reservoirs and courthouse heights. Every jump retraces a witness's movements. Every recovered clue changes the case board. Every accusation must explain the culprit, the motive, the method and the decisive evidence.

Eight original cases. Start with a short guided training case that teaches the climb, the chase, the descent, the case board and the four-part accusation one step at a time. Then open eight fictional noir mysteries, each with its own victim, suspects, testimony, timeline, red herrings, routes and outcomes. Solving a case earns a Case Key that lets you choose which file to unseal next.

Climb, chase and descend. Follow evidence through three kinds of route: climb the city, run the rooftops, drop down hidden service paths. Checkpoints keep your progress.

Build the evidence chain. Inspect documents, photographs, recordings, camera footage and physical traces. Connect evidence on the board, rebuild the timeline, dismiss red herrings, and ask for a hint when a theory stalls.

Uncover Case 17. Every mystery holds three fragments of the disappearance of Inspector Ada. Archive all 24 and link them on the season board.
