Rusty HMG skin by Crowbar Bill. Makes the HMG look old and rusty.
Crowbar Bill's Rusty HMG for Kingpin
The skin is in pak5 file. The zip file is set up so you only have to extract the pak5 file to your Kingpin directory. This will place the pak5 file in your kingpin/main folder.
If you already have a pak5 file in your main folder then extract the new pak5 to a temporary folder somewhere and rename it to another number such as pak2, pak3 etc which you don't already have. Then copy it to your kingpin/main folder.
