SWAT 4

The original SWAT game, released in 1995, was Daryl F. Gates' Police Quest: SWAT. Named after the former Los Angeles Police Chief who formed the world's first SWAT team, the original SWAT and its sequel were actually strategy games. It wasn't until SWAT 3: Close Quarters Battle was released in 1999 that the series transitioned into the first-person-shooter genre. Throughout the years, each SWAT game has attempted to simulate what it's like to lead the world's most highly skilled and trained police officers into dangerous confrontations. It's been more than five years since the last SWAT, and the newest iteration of the series is the best one yet, offering an intelligent and flexible interface, a varied and highly replayable campaign, as well as multiplayer modes that include cooperative play.
