SWAT 3: Close Quarters Battle is a tactical team-based first-person shooter game played cooperatively with the computer or human teammates as part of a 5-man police SWAT team. The game is divided into missions that represent the deployment of individual commandos in various crisis situations. The mission environment is typically indoors, requiring room-to-room CQB tactics. Operations include hostage rescue, armed standoffs, and bomb disposal. Enemies referred to as "suspects" include individuals, disorganized small groups, and trained politically motivated terrorists.
