The GameCube and Wii versions feature several minor differences in their controls. The Wii version of the game makes use of the motion sensors and built-in speaker of the Wii Remote. The speaker emits the sounds of a bowstring when shooting an arrow, Midna's laugh when she gives advice to Link, and the series' trademark "chime" when discovering secrets. The player controls Link's sword by swinging the Wii Remote. Other attacks are triggered using similar gestures with the Nunchuk. Unique to the GameCube version is the ability for the player to control the camera freely, without entering a special "lookaround" mode required by the Wii; however, in the GameCube version, only two of Link's secondary weapons can be equipped at a time, as opposed to four in the Wii version.[g]
