About the USP-S | Check Engine

The USP-S | Check Engine is a Mil-Spec Grade skin for the USP-S, found in the London 2018 Inferno Souvenir Package. Its main colours are red (94%), so it fits a red loadout. It comes in 5 wears, from Factory New to Battle-Scarred (float 0.00–0.60). The cheapest copy currently sells for about €0.35.

Float shows how worn a skin is: the lower it is, the cleaner the skin looks. Read our float guide to pick the right wear for your budget.
