I personally think they should have done it like this in the first place. The mod replaces the gray silvery color with a black shiny metallic color. It look pretty damn good in game if I do say so myself;)

It might have a problem because I made this in like 2 seconds but probably not ;)
I don't care what you do with it or if you re upload it somewhere but you should mention me as the creator.

You need texmod to use this. You know what to do.
