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, motive, method, and decisive evidence.
INVESTIGATE EIGHT ORIGINAL CASES
Open eight fictional noir mysteries, each with its own victim, suspects, testimony, timeline, red herrings, traversal routes, deductions, and multiple outcomes. The first case is always available. Completing cases earns Case Keys that let you choose which mystery to unlock next.
CLIMB, CHASE, AND DESCEND
Follow evidence through three investigation routes. Climb vertical city structures, chase leads across dangerous rooftops, and descend through hidden service paths. Checkpoints preserve progress, and route assistance helps after repeated falls.
BUILD THE EVIDENCE CHAIN
Inspect documents, photographs, recordings, camera footage, physical traces, keys, containers, and personal objects. Connect evidence on an interactive board, reconstruct timelines, challenge testimony, dismiss supported red herrings, and request graduated hints when a theory stalls.
MAKE YOUR ACCUSATION
Choose the culprit, motive, method, and decisive evidence. A strong result depends on reasoning and recovered evidence, not on watching ads. Incorrect and partial theories return you to the evidence instead of ending the investigation.
UNCOVER CASE 17
Each mystery contains three fragments connected to the disappearance of inspector Ada. Archive all 24 fragments, link them across a persistent season board, and uncover the system behind Greyglass's altered records.

OPTIONAL ADVERTISING
Murder Jump includes clearly labeled rewarded ads for optional conveniences such as a checkpoint revive, doubled run evidence, a chase skip, a clue reveal, or one Case Key. Completing a case also awards a Case Key, so advertising is never the only path forward. Interstitial ads may appear only after an eligible failed run and are frequency limited; they never interrupt active traversal or deduction.
Murder Jump is an original fictional story. Its characters, organizations, cases, and locations do not depict real people or real crimes.
Chase leads across rooftops, connect evidence, and solve eight noir mysteries.
