Quick question
there are 3 maps present, I recognize 2 as a normal and the other diffuse
whats the other?

from left to right:
-Diffuse/Color
-Specular
-Normal map
...although, if i would use this in our game i probably would consider removing the specular map and use a channel from the diffuse, tweak it a bit in the shader (multiply/tint/contrast).
But that is more a matter of "some more instructions in the shader" vs "texture fetch+memory cost" vs "the final look"

What does the specular map do exactly?
the specular map describes how the highlights (light reflection) will look, the lighter areas in the specular map is the more light those areas will reflect, making it more shiny.
By using the diffuse/color as base when creating the specular i can get the hightlights that somewhat matches the features in the diffuse.
this tutorial is really great if you want to learn (one way) to create really nice specular maps.
