AtmosFear is a mod for S.T.A.L.K.E.R. - Call Of Pripyat that tweaks and expands the vanilla weather system to be more realistic and various.
First of the videos presenting new features of upcoming AtmosFear 3 for S.T.A.L.K.E.R. Call of Pripyat. This one focuses on the nights. They will feature real moon with dynamic shadows and changing phases. The nights will be slightly longer (as for August in Ukraine).
