Purple NV, backup your original nightvision files (gamedata/anims) and that's it.
Credits to Green Hawk for this cool night vision effect.
It is compatible with S.T.A.L.K.E.R. Shadow of Chernobyl, Clear Sky, Call of Pripyat and also of course Call of Chernobyl.

Super. Will use it in my mod. I'll give full credits. This is much better than standard NV.
