The set of textures having such plain name not only replaces textures, but adjusts shader effects of portals. Holes in space became more animation, similar that we saw in early versions of game. The author also changed textures of automatic turrets and the most portal gun. It became all black, with glossy brightness. All this isn't inscribed in the general stylistics of game a little, but for the sake of change of the bothered original and beautiful effects of portals it is worth setting a set definitely.
