I say up to date, I'm missing a few image, waiting for Minininho02 to do those. But basically, all articles are filled with accurate information to the best of my knolwedge.
Also, there might be some skins that I'm missing due to PR being bad with update logs. An example of this is Fair Warning. IF YOU BOGUHT A SHITLOAD OF SKINCRATES AND USED THEM ALL ON ALL WEAPONS PLEASE TELL ME IF IM MISSING ANY SKINS ON THE WIKI. YOU WILL INSTANTLY GET WIKIA CONTRIBUTOR II.
