To create an FPS where you control with the mouse, you need to turn ON the following two trigger settings:
Camera -> Turn Camera Mouse Rotation On/Off
Camera -> Lock Camera Mouse Relative Mode On/Off
Enabling both of these will allow you to "look around" by moving the mouse. You can then use "Camera -> Camera Pitch of Player" and "Camera -> Camera Yaw of Player" to determine where they are looking.
You'll also need to modify the camera position to follow whatever unit you want to follow.
