is just some dirty 3d painting.
You'll notice in the texture bellow. Just save it. don't resave it with a 2d software in jpg format, do it in bmp..is crappy enough already without loosing more..


Just anarkrave said he did not add the weapon as no texture...well, u have now all the md2 (you'd need to do the trick for the shading you did) and a somehow quick raw texture...
