Question
I see custom maps on the servers but I can't join.
Answer
L4D / L4D2 does not support in game custom downloads.
In order to play on a custom map, you must have it previously installed and it must eb the same version as playing on the server. You can download any custom maps playing on the SunLit servers from the Downloads section.
