Operation-exclusive Collections – Operation Shattered Web
Operation-exclusive Collections drop skins through the weekly drop scheme only to those players who have the current CS:GO operation pass. The Cache, Chop Shop, Cobblestone, Gods and Monsters, Overpass and Rising Sun collections were exclusive to operation pass-holders during Operation Bloodhound, Wildfire and Hydra. For Operation Shattered Web three new collections were introduced: Canals, Norse and St. Marc.
Active Collections drop skins through the weekly drop scheme. During an operation the skins from these collections drop to players who do not own the operation pass.
In-active Collections are not available through the weekly drop scheme. The skins from these collections can only be acquired through opening souvenir packages or gift packages, or through trading and the Steam Community Market.
Retired Collections do not drop at all making it impossible to acquire any of the skins from these collections except through trading or the Steam Community Market.
The Blacksite Collection was only available during the first few weeks of the launch of the Dangerzone game-mode.
