Daryl F. Gates' first game for Sierra departed completely from the style of the previous games. The player was no longer cast as Sonny Bonds, but as John Carey; the action was no longer in fictional Lytton, but in Los Angeles, California. Carey, an LAPD homicide detective whose best friend was killed in the line of duty, must track down a serial murderer in L.A.  Numerous mature themes are depicted in the game, including hate crimes, Neo-Nazism, and youth involved in crime. Graphic imagery within the game also includes the body of a child murdered by gang violence and a severed head in a refrigerator. Using SCI2 the game replaced from earlier games with scanned photos as backgrounds, and live actors filmed from green screen as character sprites. It was released in 1993, for both IBM PC and Macintosh. The game is generally incompatible with Windows 95, and later editions; the game may crash at certain points in the game, e.g. the shooting gallery and the shoot out. This, however, was fixed with the release of the CD version with Windows installer. This game is the most "mature" of the "Police Quest" series of games; while previously only a peripheral element, the themes of drug abuse, police corruption and gang violence play prominent roles in this game. Police procedure is less of an element in the game, pushed aside for the sake of storytelling. Although the game is not referred to as PQV in the title screen, it is referred to as such in several other locations in the game including the files, and the game credits, and certain versions of the packaging near the ISBN/barcode and documentation. "Police Quest 5: SWAT" was re-released as part of the second "Police Quest Collection", and later as part of the "Police Quest: SWAT Force", "SWAT Career Pack" (which included all six PQ games), and "Police Quest: SWAT Generation" compilations.   "" is the sixth and final game of the original "Police Quest" series. It is a real-time strategy game using an original game engine. It retained only a few adventure game elements in the form of an inventory and use of a few "puzzle" items such as a pizza (to draw a suspect out of a house), and similar interface (look/search icon, pickup/hand icon, communication/talk/challenge icon, etc.). It is referred to as PQ6 in a few locations including its files.
