Scorpion skins are recognizable for their unique paint job that prominently features a depiction of a red scorpion on the side. At the moment, only one skin is a member of the Scorpion family and it is P2000 | Scorpion. This skin was added to the game way back in 2013 as a part of the Arms Deal Update. It is also a part of The Dust Collection and only comes in two out of five possible exteriors, these being Factory New and Minimal Wear.
