Weapon Skins for all weapons in a mirror like/reflective style by [GT]*Knight*
The reflective weapon skins are in a pak3 file. Just extract/unzip the file to your Kingpin folder. This will place the pak3 file in your kingpin/main folder.
If you already have a pak3 file in your main folder then extract the new pak3 to a temporary folder somewhere and rename it to another number such as pak2, pak4 etc which you don't already have. Then copy it to your kingpin/main folder.
