In World of Tanks, if you click "v" your battle icons go invisible. The list of players, you tank status box and you map go invisible. Basically all you see is your tank and the terrain around you. As if you were a person viewing the battle from a real point of view. The icons come back by re clicking the "v" button. It is not useful at all in the actual battle, unless you are challenging yourself. But I would like to use something like this in World of Warships to record the ships a different times if it is allowed. You could then get "cool" shots of ships without all gadgets and icons surrounding the screen.
