Fallout 3 Mod

Don’t know if it’s requested before, couldn’t find it.
Like Fallout 3, it would completely pause the entire game, and then zoom in on your enemy (zooming in isn’t necessary + the enemy needs to be on crosshair) and everyone’s frozen, it detects joints on the enemy so you have the option to shoot him in the head or in the leg or in the arm or throw a grenade to him or whatever. Impossible? Okay then.
