Aperture Science Vs Black Mesa Bonk! energy skins.
The long fought Black Mesa and Aperture war still continues, so I thought I'd contribute, considering I have not yet submitted anything BM or AS related, until now.
Regular retexture/recolor, you get the jist of the situation.
A very subtle bump map was added on as the finisher.
Also thanks again to CYoung for the sexy render.
