How do you rotate the upper torso with mouse?

Can you explain more what you’re working on? Perhaps with some screenshots of the issue or a video.

I’m having a lot of trouble with moving the head up,down,left, and right when moving the mouse. The head stays looking forward when the mouse/camera is looking down, how could I fix this?

It wont move his head with the mouse, it wouldn’t be a problem except your able to shoot. So the head needs to move with the camera.
