It would be cool if a patch by TDW could switch the usage of alternative foggy periscope masks, is any of our scopes gets damaged... |
You are talking about 'fogging' or 'clouded' lenses and whole optics.. but as I saw in the screen, I saw really dirty and not fogging lens..
And yes, it would be a cool feature if masks will change after damage..
