I tooked the “MouseLook” script (you get this script with the “Islands” project) and you put it on your player (because my player is without hands I put it on his body, but you can put it on his hands or any part in the body of the player) and when you move the mouse the player moving in the same way.
You need to use the ShooterGameCamera.cs script.
You attach it to your camera, and you make an empty GameObject in your scene used to be the aim target.
