This mod replaces all the natural Bone County textures, such as dirt, sand, tracks, rock, cliffs, and such, with snow. It looks simply amazing. I reccommend using the fog cheat for optimum effect, gives it a snow storm appearance. I used the snow texture from the LC cutscene, from the St. Marks Bistro so it looks as good as snow will ever look in SA.
2.0-Area 69, Tierra Robada, and the long distance models/lod's now have snow on them.
