In Barricaded Suspects mode, polish clan <|UZ|> has re-opened their Custom Map server - named "POLAND POLAND NEW MAP". The server was opened initially a few months back but taken down due to a lack of players on the server. However, it is now live again and is unique in the sense that one doesn't have to download any map whilst connecting - meaning you don't get kicked if you don't have the .s4m file in your directory.
