Police Quest 4: Open Season

Police Quest: Open Season is the fourth installment in the Police Quest series. It abandons the story arc of the previous three games, introducing a new setting and a new protagonist, homicide detective John Carey of the Los Angeles Police Department. Carey finds his best friend and ex-partner, Officer Bob Hickman, murdered in an alley in the Southern part of the city. An eight-year-old boy named Bobby Washington has been murdered as well. Carey begins an investigation that leads him deep into the criminal life of the city and a hunt for a maniacal murderer.

The game utilizes Sierra's traditional icon-based interface for interaction with the environment and generally follows an adventure format. However, it focuses on realistic police procedures even more than the previous games in the series. Much of the gameplay is dedicated to examining crime scenes, questioning suspects, and conducting a by-the-book investigation. There is a considerable degree of freedom in the interaction, allowing the player to perform actions not connected to the main story, some of which will, however, lead to the protagonist's death. The game utilizes digitized photorealistic images for its visuals.
