The game uses a third-person perspective with illustrated scenes and a mouse-driven interface. Players examine locations, question witnesses, collect evidence, operate police equipment, and travel between calls and investigations.

Progression is divided into connected incidents and case stages. Correct procedures, careful observation, and appropriate use of evidence are required to move the investigation forward. Incorrect actions can lead to failure, so saving regularly and reading reports closely are important.

Follow department procedures instead of rushing through scenes. Examine every relevant object, question people carefully, and keep track of evidence and information from reports.

Save before major decisions, traffic stops, confrontations, and unfamiliar interactions. If progress stops, review earlier locations and consider whether a required procedure or piece of evidence was missed.
