Valve have decided to officially support a community made Left 4 Dead 2 campaign called Warcelona. Meaning, once you've installed the custom map pack you'll be able to search for games using the Left 4 Dead's native search client. While the installation is a bit of a chore, Valve have revealed that it will be much easier soon as Left 4 Dead's Steam Workshop component is finally entering private beta and so shouldn't be too far from release, hopefully.
More on how to get hold of the campaign after the break.
The news of the Steam Workshop integration entering beta came from the Left 4 Dead 2 blog: "The Left 4 Dead 2 Workshop has been in a test beta and will be expanded into an invite only private beta this week." If you've been playing Skyrim or Portal 2 you'll likely be familiar with the advantage Steam Workshop brings to installing mods. It's as simple as browsing the community tab in Steam and subscribing to any that take your fancy. If you've not yet sampled the delights on offer I'll just subtly point you to our collection of some of the the oddest Skyrim mods.
The other news from the blog post, that community-made campaign Warcelona has received official server support is wonderful. The campaign's four maps cover a (largely) faithful recreation of the route between the Sant Roc church and the National Art Museum of Catalonia in Barcelona.
See for yourself in this trailer I shamelessly ripped from the dev's Youtube channel:
Installation is a little complex at the moment, certainly not as easy as just clicking a subscribe button. To get the map pack into your game you'll first need to download it, then copy it over into your '\Steam\steamapps\common\left 4 dead 2\left4dead2\addons' directory. From there you'll be able to select if from the map list in game and with any luck find a few fellow zombie apocalypse survivors and - via an axe - take the fight to the recently dead.
We'll give a shout out when Left 4 Dead 2's Steam Workshop activates.
