A new fan-made campaign for Left 4 Dead 2 known as Warcelona is now available to download, however installing it is a little complex at the moment.

The campaign is made up of four maps and recreates the route between the Sant Roc church and the National Art Museum of Catalonia in Barcelona. If you wish to give the map a try you can find full instructions on how to download and install it over on the Left 4 Dead blog.

You can have a quick look at the campaign in the video below.
