Valve is adding another community campaign to its official Left 4 Dead 2 servers, "Warcelona." It joins the other recent campaign, Cold Stream, but the bulk of today's update is news on how the new Workshop features will simplify finding campaigns to play.
The L4D2 Blog says the Workshop features are about to enter private beta this weekend. Workshop users will get to click a button to subscribe to a new map like Warcelona. The announcement doesn't detail when the Workshop might go live for all users, but it does invite players to stop by for a "meet the creators" event. It will kick off on Saturday at noon PST in the Official Left 4 Dead Game Group.
