[Fu Xuen]

As I made some nearly invisible skins ('predator'-like ones, available [url=http://www.alliedassault.com/pafiledb/pafiledb.php?action=file&id=515:7a103]here[/url:7a103]), it is possible to make totally invisible ones. But you can not 'see' it (well, hope you understand what I'm trying to say) unless you AND the server have downloaded them. Maybe some funny guys have made a cool mod/map/skin you dowloaded, but they included the invisible skins in the pack... Just explore your uniform skins in the multiplayer options to see if there is an hiding one.
