Unlike previous installments in the Police Quest video game series, which followed LAPD SWAT officers through missions set in Los Angeles, California, the single-player campaign of SWAT 4 takes place in fictional East Coast city of Fairview (an amalgamation of New York City, Boston, and other eastern cities), during the game's then-future of 2008 to 2009. In SWAT 4, the player leads a SWAT tactical element in resolving various situations, such as hostage standoffs or apprehensions of dangerous subjects, simulating the experiences of real-life Special Weapons and Tactics officers. It was built on Irrational Games' Vengeance Engine powered by Unreal Engine 2 technology.
SWAT 4 is a 2005 tactical shooter video game developed by Irrational Games and published by Vivendi Universal Games exclusively for Microsoft Windows.
