With genres such as action, adventure games, platforming, and shooting, the left stick normally controls the character's movement while the second stick controls the camera. The use of a second analog stick alleviated problems in many earlier platform games, in which the camera was notorious for bad positioning. The right stick not only allows for camera control in third-person games, but is almost essential for most modern first-person shooters such as Halo, where it controls the player's gaze and aim, as opposed to the left stick, which controls where the player moves.
