CS2 Collections

Updated 2026-11-11 · Skins

Every map, operation and Armory collection in CS2, with what each one can give you in a trade-up.

Every CS2 weapon skin belongs to a collection, and the collection decides what a trade-up can give you: a contract only returns skins from the collections of its inputs. Case collections are on the case pages; this page lists the other 49 collections (maps, operations, the Armory, weekly drops and Terminals), each with a page showing every skin, its float range and what every rarity trades up into.

Frequently asked questions

What is a collection in CS2?

A set of weapon skins released together, for example with a map, an operation or a case. Every weapon skin belongs to a collection, and trade-up contracts only return skins from the collections of their inputs.

Do collections matter for trade-ups?

Yes. The result always comes from the collections of your inputs. Valve doesn't publish the exact odds; the model calculators use gives each input's collection a 10% share, split evenly over that collection's skins one tier up.
