where would i get L4D2 skins and maps?

How would I go about using L4D2 skins and maps…I have the game but it’s not on there (map select or even the models) like TF2 or Counter Strike is. what must I do O great geniuses of Facepunch?

Rephrase that gibberish to a complete sentence.



Don’t know if it works for L4D2 though. But that’s what I use mainly.
