Editing First person view

You can enter and exit the first person view with the key combination alt+f. For ranging small targets like rabbits and racoons it can be very helpful.
You will be able to shoot a target, to pick up bags and to move over the map while you are in FPV.
The downside, you can not view what is behind you. But you will not be stoped from ranging a target because it is obscured by trees. When you move under the treeline it will be more easy to see if a target is behind a rock or a bush. The "no line of fire!" exception will happen to you less often.
