Full concept MODIFICATION of S.T.A.L.K.E.R. Call of Pripyat that touches every game aspect including textures, sfx, music, weapons, A.I., items, weather, mutants, difficulty and much much more!
There's too much to say. All I can say is that the mod wasn't perfect (although that may be because of personal preference in terms of difficulty and other factors), but it surpassed my standards and raised them in the process. I can't play another mod now because of this.
