Z Button = Fire Weapon (3)

Configure your aiming options in Perfect Dark (2000), including Reverse Pitch, Look Ahead, Head Roll, Auto-Aim, and Aim Control.

Aiming Options:

• Reverse Pitch: Changes the direction style your aiming mechanism (the way you aim) goes.
• Look Ahead: This lets you see ahead during gameplay. It is suggested to leave this setting on.
• Head Roll: This allows you to turn your head fully around when looking.
• Auto-Aim: When set on, this will hone in on enemies during fire.
• Aim Control: You can select 'Hold', where you have to hold the aim button, or 'Toggle', where it is automatically set when the corresponding key is pressed.
