Featured campaigns are Custom Campaigns for Left 4 Dead 2 that were elected by Valve for their outstanding quality. Featured campaigns are uploaded to all official dedicated servers for an unspecified amount of time. They are announced in blog posts with a short description and a link to the download. Featured Campaigns are presumed to remain on official servers indefinitely (except Dead Before Dawn; see below). Valve will attempt to keep the most up-to-date version of a featured campaign uploaded to the servers. __toc__
