A different slant on power. A true to life generator where you can see how the power is made and transported though the facility by wires connecting each other. The "core" in the generator room really makes it look important and dangerous, because of the moving parts inside. The whole thing is representitive of a real generator... who said you couldn't map reality?
One other note: texturing. If there was more time, Howdy could make the map feel more living if he applied more detail on the walls, because they look quite boring without it...
