The game uses a first-person, room-based adventure perspective with illustrated scenes and a text parser or interface commands. Sonny investigates locations, examines objects, speaks with witnesses and suspects, collects evidence, and performs police duties.

Progression is largely linear. The player travels between locations, completes procedural tasks, and uses information from one scene to solve later situations. Incorrect actions can lead to failure, so careful observation and regular saving are important.

Read every available description and examine relevant objects before leaving a location. Police procedure is central, so avoid skipping steps or choosing an aggressive response without clear justification.

Save before major investigations, conversations, and potentially dangerous encounters. If progress stops, revisit earlier locations and look for an uncompleted action rather than guessing randomly.
