The Cache Collection is a map collection of 13 skins added to the game in 2015. It spans rarities from Industrial Grade to Restricted, featuring two Restricted skins. SkinsMonkey lists every The Cache Collection skin with prices for each wear level.
The Cache Collection was first released in August of 2014 alongside the ESL One Cologne 2014 update. It is one of the CSGO classics, just like the corresponding Bomb Defusal map, which is set at the nuclear power plant in Chernobyl. The skins included in this collection are ideal for players who are tired of traditional military prints and patterns, but are not quite ready for neons and graffiti. They feature interesting color combinations, mostly consisting of greens, reds, and yellows, that often resemble toxic waste and warning signs. Very much on theme.
