Criterion intended to "do for shooting what Burnout did for racing - tear it apart",[1] with dual emphasis on destructible environments and the handling and behavior of real-world firearms. Bullets that hit buildings, terrain and objects leave visible damage; moreover, the guns are rendered with great detail and accuracy, though some weapons' features are stylized or exaggerated.[2] The emphasis on the appearance, function, and sounds of the weapons led the developer to label the game as "Gun-Porn".[3] Another notable and original feature is the use of real-time blur while reloading, giving a depth of field and more perspective to the game. Similarly, when the player drops below two bars of health, the screen turns black and white, the sound of the character's heartbeat become the dominant noise and the game goes into slow motion, and the large and small motors in the control pads match the sound of systolic and diastolic part of the heartbeat.
