All files included are in .dds format, just import over the existing skins. You should be able to tell what goes where, though if you're having trouble you might have to ask someone to make a .ppf patch (I don't have time; sorry). Note that you will need to install the multi after the FP skin, otherwise the multi will become corrupted and the shiny areas will go crazy ingame. You will also need to back up the original reticles because there's a chance that installing mine will corrupt them a little. If that happens, just re-import the backups and everything should be just fine.
