About the specular map, it is the map that tells the engine how shiny a surface is, it is needed to make wood look like wood and metal look like metal, the specular map don't need to be gray scale it can have color on it, for example you can give a tint of blue to a metal specular map to give the highlights a blue look, the rule of thumb of a spec map is that more brighter is the spec map more shiny is the material, so the flesh thing on Amnesia use a bright spec map to give it that wet and fleshy look.
