SWAT 4

SWAT 4 is a 2005 tactical first-person shooter video game developed by Irrational Games and published by Sierra Entertainment (Vivendi Universal Games) exclusively for Microsoft Windows. It is the ninth installment in the Police Quest series and the fourth installment in the SWAT subseries. In SWAT 4, the player commands a police SWAT team in the New York City metropolitan area. Unlike its predecessor, SWAT 3: Close Quarters Battle, SWAT 4 does not have an overarching plot. Instead, gameplay takes place over a series of mostly unconnected deployments of the player's SWAT team, as they are sent to apprehend criminals, terrorists, gangs, and cults in and around New York City.

SWAT 4 was built on Irrational Games' Vengeance Engine powered by Unreal Engine 2 technology. Like the rest of the SWAT series, SWAT 4 places heavy emphasis on following proper police procedure, minimizing casualties, and ensuring the safe apprehension of enemies as opposed to simply killing them.

The game was well received by critics and players. An expansion pack, SWAT 4: The Stetchkov Syndicate, was released in 2006.
