Set in the immediate aftermath of the zombie apocalypse, Left 4 Dead's survival co-op mode lets up to four players blast a path through the swarming zombie hordes and terrifying mutant monsters. Guide your survivors across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests in your quest to escape a devastated Ground Zero crawling with infected enemies.

New technology dubbed the "AI Director" is used to generate a unique gameplay experience every time you play. The Director tailors the frequency and ferocity of the zombie attacks to your performance, putting you in the middle of a fast-paced, but not overwhelming, Hollywood horror movie.

Some more news has been released via the Left 4 Dead blog about how exactly the new user created custom content is going to be implemented into the game. This will all be done by using an add-on platform and the new VPK file system.

Valve wrote:Third party campaigns are designed to be installed using a new Add-On framework. Content authors will be able to package up their new maps, along with new posters, models, and textures, into a single .VPK file. To install and activate this content in-game, players need simply download the .VPK and double click on it. Alternatively, they will be able to drop it into a new "addons" folder. The list of installed add-ons will be viewable from a new item on the 'Extras' main menu flyout.

It's nice to see that Valve has decided to make installing and playing custom content as easy as possible, and with the update to the matchmaking system if players do not own the VPK files needed for the custom campaign then it will be offered to them to download.

Valve wrote:When creating or searching for a lobby, a new option named "Add-on campaign" will let you select from among the add-on campaigns that you have installed. You can then find games or lobbies as well as create a lobby for that campaign. You can invite your friends, too. If they do not have the campaign installed, they will automatically be offered and an option to download it. We've also made it easier to create lobbies by adding a 'Create Lobby' option directly from the 'Play Online' menu. Once you're ready to go, the new matchmaking system will automatically try to find any dedicated servers nearby that have the custom add-on campaign installed, or you can make your own local server.

On my quest for answers on what exactly the VPK file is I managed to find that everyone's favourite Source SDK development program GCFScape now supports VPK files too. It turns out VPK is just a another variation on the GCF file that populates most Valve games, so being able to use others work looks like its possible, not sure what the copyright would be on that either. The last piece of news from this update is that as of this patch going live the L4D Authoring tools/SDK will go live as well. I would still like Valve to give modders access to a full SDK for L4D as the director in modding hands could see some great things be developed, but as of right now it does not look like it's going to happen. A shame really.

When Left 4 Dead came out, people where bitching and complaining about there not being enough content for the game, now Valve is making more content and people are bitching and complaining about that now. Get your priorities straight.

I'm bitching and moaning because they promised DLC content, not an entirely seperate, full-price retail game. Everything they've shown so far could easily be imported to L4D in a large update.

ok really this argument has been beat like dead jackass (donkey). Like really your getting a new god dam campaign, got ******* survival mode, what more do you want? An arm? Also putting in what they have now would break the balance of the game, cause you to have to download like a ******* gb or 2 at least of content and not to mention you will still bitch that there is something missing so really get off it you cry baby

What argument? That there should be an SDK for Left 4 Dead 2? I wasn't aware that was being debated or argued. Coming from a Valve game it should be something expected. When you say something like that then you're implying that you dislike mods. If so then why are you even on ModDB? Don't flame or make comments like this without thinking about what you're typing. It makes you sound like an idiot.

They already gave a dlc for l4d and another is on the way... and im sure they will add more to l4d after l4d2 since they are working on making it cross compilable so you can play online with ppl from both games.

Valve never said they wouldn't support Left 4 dead
They said they would make a new game but does this mean they are just going to shove aside left 4 dead and make left 4 dead 2 take the spotlight? It doesnt at all.

Hey, quick introduction before I get on with what I want to really say. I'm a brand new member and I don't have any semblance of a reputation on this site, so I'm not trying to be pretentious or have un-warranted self-importance.

However, I have a (very) basic idea for a L4D mod. Since I have no skills in programming, modelling, or mapping; all I have are words on paper. As it stands I only have the idea for 4 new characters set in the city of Montreal during the winter of the first year of the new zombie-apocalypse. What I would like to do with this is provide more information and work on more information for any team interested in making such a mod. Please send me a message and I will give you far more information on said characters (a bio of each one) as well as some ideas I have for gameplay mechanics. If I find someone(s) who shows interest, I will be happy to write even more backstory and help with brainstorming for campaign themes.

Much obliged, Teh_Caspy
