How Do CS:GO Cases Value? CS:GO cs2 cases are containers where players can purchase skins for weapons and other cosmetics. The cases can also contain items called StatTrak, which add a kill counter to knives or weapons. Some of the most expensive CSGO cases are the Bravo Case, Huntsman Weapon Case, Spectrum Case, and Operation Hydra Case. These cases are worth the price for investors and collectors. However opening these cs2 cases to make profit is not advised. Prisma 2 Case The Prisma 2 case is a new weapon case that comes with a great set of skins.
