The control menu is the mouse setting of the keyboard mouse player and the right joystick setting of the handle player.

Control menu

Aiming Sensitivity: Adjust the aiming sensitivity to suit your mouse and aiming feeling.

Custom key binding: especially for other shooters, adjust some key settings to suit your feel.

Think of the mouse side key as ESC: If you often touch the mouse side key by mistake, it is recommended to turn this option off to prevent it from affecting the game experience.
