The Operation Hydra Collection is the weapon collection of the Operation Hydra Case, added to the game in 2017. It holds 17 weapon skins, from Mil-Spec Grade to Covert. SkinsMonkey lists every Operation Hydra Collection skin with prices for each wear level.
The Operation Hydra Collection is the set of 17 weapon skins tied to the Operation Hydra Case. Every skin in the set shows The Operation Hydra Collection in its in-game details. The case also drops 6 glove models as rare special items: Bloodhound Gloves, Driver Gloves, Hand Wraps, Moto Gloves, Specialist Gloves and Sport Gloves. Gloves are not part of any collection, so you will not find them in the list below.
A trade-up contract takes 10 skins of the same rarity and returns one skin of the next rarity up, picked from the collections of the skins you put in. Fill the contract only with Operation Hydra Collection skins and the result is always a skin from this set. StatTrak and regular skins cannot be mixed in one contract. Since the CS2 update of 22 October 2025, five Covert skins can also be exchanged for a pair of gloves from the collection of one of the skins used. With five Covert skins from The Operation Hydra Collection, the gloves come from the Operation Hydra Case pool.
The Operation Hydra Case page covers the container itself, and all CS2 collections are listed on one page.
