When you look back over your right shoulder the periscope lens appears in a black box outside of the canopy.
On another point when your in the periscope view it shows the word ammo in the top left hand corner but there is no count for shells. Also it wont fire the cannons in the periscope view.
Yet it will fire from the pilots seat as well as F3 mode.
Since we have rear view now from the periscope should F3 mode be enabled?
So with cannons should they not fire through the periscope view?
