Police Quest: In Pursuit of the Death Angel is an adventure game (and police simulation) produced by Jim Walls for Sierra On-Line, and originally released in 1987 built on their AGI. It was remade in 1992 using 256 color VGA graphics and the SCI engine, which dramatically improved the appearance and audio of the game, and replaced the command line interface with point and click.
It is the first game in the Police Quest and SWAT series and spawned two direct sequels, Police Quest II: The Vengeance and Police Quest III: The Kindred, as well as Police Quest: Open Season, Police Quest: SWAT, Police Quest: SWAT 2, SWAT 3: Close Quarters Battle and SWAT 4.
Police Quest: In Pursuit of The Death Angel, is an adventure game whose gameplay is centered on interacting with the environment to resolve a series of scenarios. These largely revolve around typical police work, such as securing crime scenes and recovering stolen vehicles, plus some important duty procedures. The original release of the game required the player to type in the desired actions, such as opening doors, pressing buttons or firing one's gun, while the remake allows the player to use the mouse to select actions from a menu and objects in the environment.
The lack of "traditional" puzzles made the game stand out at the time of release, although it also resulted in some criticism of the dry police work. Unlike many games of this genre, the style of play depends largely on a strict adherence to standard police rules and procedure. Failure to abide to proper procedure typically leads to the player being penalized on points, or having his character killed. For instance, if Sonny neglects to store his side arm in a gun lockers before entering the jail to book a prisoner, the prisoner will take the gun from him the moment his handcuffs are removed and shoot him with it, ending the game.
