Draft articleThis CS2 explanation is being researched and checked for version scope, source length and links.
The collection arrived with The Armory update. A cached Armory listing records a four-star offer cost; that is a dated listing detail, not a promise of current availability or price. Armory offers can rotate, while the collection’s release date remains the historical boundary for the set.
The Overpass name describes the collection’s theme. It does not state that the map was added to a rotation or changed. See Overpass for the map and The Armory for the collection offer system.
The collection contains 16 named weapon finishes distributed across rarity tiers. Each finish is tied to a specific CS2 weapon, so the complete identity is the weapon plus its finish name. The collection grouping helps players recognize the common theme; the individual weapon page explains the base item.
A finish affects appearance and does not alter firing, recoil, damage, ammunition or movement. The weapon remains unchanged in play. The Armory context explains access at release, while Weapon Skins explains cosmetic finishes as a broader system.
