Police Quest: In Pursuit of the Death Angel

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 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.
