Follow the Liter
Scavenge one can at a time.
No more fighting over what cans to grab first. This Mutation spawns only one group of cans at a time, so survivors know exactly where to go. There is only one problem: the Infected know exactly where they are going.
This presents a different strategy from regular Scavenge mode and actually tips match in favor of the Infected.
Infection!
Besides working on getting the DLC out on the 360 and playing L4D2 ourselves, the team has recently started playing some other zombie infection related games we thought we would share.
Our most obvious pick is Telltale’s
The Walking Dead: The Game - Episode 1 available on Steam. If you love the comic and like the TV show as much as we do, the game is a great addition to the franchise.
Just this week,
Pandemic 2.5 was released on the IOS. We played this game a ton on the PC while we thought about how viruses spread. While it is not a scholarly study like the book
Flu, it is quite a bit more fun. With its release on the iPhone, you can now plot the world’s demise while sit in the Doctor’s office waiting for your appointment.
Let us know in the forums or on Facebook what games you’re playing.

Today we have released a pretty big update for Left 4 Dead 2 that includes map bug and exploits fixes.
These changes will be coming to the Xbox 360 with the title update that will accompany Cold Stream’s release. Before we send the game off to certification, we want to test these fixes on the PC. So please, give these maps a play through and tell us what you think.
The Cold Stream DLC will include 21 maps in total - the Cold Stream, Blood Harvest, Crash Course, Dead Air, and Death Toll campaigns. Besides the massive amount of new content, 360 users will also be getting many of the bug fixes and changes we have implemented since the last update.
We don’t have a release date yet, but we will make sure to post the minute we do.

Last Man On Earth
You will become legend to the infected as the last human left.
You are the only Survivor left in the world. No split screen help. No Survivor bots. But don't worry you aren't entirely alone. While there are no common Infected, Special Infected will hunt you down and become close, close friends with you.
Loners?
While the first part of this blog post should make the results of our last poll obvious, the second place finisher is just as interesting. Between Lone Gunman and "scared to play alone," seems about 30% of you are "scared to play alone" – putting that choice in second place. With that being true, today is a great day to overcome that fear and play Left 4 Dead 2 alone with Last Man On Earth.
After all, it is Friday the 13th, what could happen?

The first Survivor team sets the time. The second team tries to beat it. Then the first team tries to beat the second team's time. Then the second team tries to beat the first team's time. And then the... you get the idea. Rounds keep switching until someone fails to beat the previous time.

Blast the infected to shreds with M60s.
Swords can slice up some fun. Chainsaws can tear apart the infected. But you need to get close for both and well… chainsaws are really loud! Time to go with the ultimate gun, you and three friends armed with M60s and unlimited ammo. This is going to get messy.
Cold Stream
As we recently posted on our blog, we are busy working on the full Cold Stream DLC which will include Cold Stream, Blood Harvest, Crash Course, Dead Air, Death Toll, and No Mercy. We will be updating Campaigns on Steam with bug fixes as we get ready to ship the DLC.
Check the release notes as the list of fixes is extensive. The Xbox 360 will get Campaigns with the bug fixes at a future date.

If you have been playing Left 4 Dead 2 for a bit, you probably have your own lists of who is naughty and who is nice. We already make it easy for you to track who is being nice – we have the Steam Friends list. But we know people can rage, players can grief, and some people… well some people you just don’t want to play another game with.
For those special people, we have the blocked list. Think of it as your own personal naughty list. Not only will those people not be getting gifts from you this holiday season, they also won’t be joining you in any games, reindeer or otherwise.
Once you add someone to your blocked list, they will not be able to join your game. This means they are blocked through the lobby interface, the server browser, the recently played list, and even direct connecting. They are gone from your life.

This is a great way to try Versus. Rounds are only as long as you can keep beating each other’s times. There are no rushing Survivors. Infected spawns get quicker as the time increases. It is mayhem filled with all the weapon perks and items. What’s not to like? Give it a try.

Overall the Mutations and weekly polls have been a great success and an amazing way for us to get feedback from the community. Don’t worry we still have more Mutations coming and we will also be tweaking and bringing back some of our favorites.
The idea behind the Mutations was simple. Left 4 Dead 2 is played by many different players and types of players. Some players have 300+ hours played in almost daily games and some players only play in weekly casual games with friends. We wanted to create weekly events that mixed up the game rules to experiment with gameplay and made people look at the game in new ways.

In the first two months of Left 4 Dead 2's release, 28,981,249,043 zombies have been shot, bludgeoned, chainsawed and killed — or, for our younger readers, taken to a farm where they can frolic and shuffle around forever.
You read that correctly: 28 BILLION. To put that number in perspective:

With our last
update having come out a few weeks ago and the next one a few weeks out, we wanted to let people know what we are working on. In addition to "The Passing" DLC, we are working on some other updates coming for both PC and 360. While not a complete list by any means, we wanted to give a heads up on a few Versus changes coming.

We are releasing the Left 4 Dead 2 Authoring Tools and Left 4 Dead 2 Add-on Support today.
PLAYERS:
If you are not looking to design but play custom campaigns all you need to do is install the add-on support package. Just go into steam and open up the
Tools tab. Look for the entry labeled
Left 4 Dead 2 - Add-on Support click and install it. This download is sizable, but will update your L4D2 installation to allow running ANY map, including custom maps made for the original
Left 4 Dead. Once installed, you do not need to run this application, it will always be active.
We will be updating the Left 4 Dead 2 game UI to include links to this package when applicable but for now please just download it directly. If you see any missing textures or models from your favorite map let us know in the forums.
DESIGNERS:
Besides also downloading the above file you will need to download the
Left 4 Dead 2 - Authoring Tools. Downloading it will add applications, utilities, and example files that are useful for building L4D2 game add-ons. These are similar to the tools released for Left 4 Dead, but include many updates and new features. Among the most useful are:
Gamemode Logic: Designers can now make a single map that can behave differently depending on the gamemode in which it is being played. This can dramatically reduce the file size of Campaign add-ons, as the same map can be used for Co-op, Versus, Scavenge, and Survival.
Director Logic: Maps can now alter their layout and behavior depending on how "angry" the A.I. director is. The better the Survivors are doing, the angrier the AI Director seems to get. This allows you to base variable paths and other events on the player's skill and current conditions.
Scavenge Mode Support! All the elements map authors need to support Scavenge in their maps. This includes game props as well as a full example in the form of Deadline 2, an updated tutorial campaign.
We have included an updated tutorial to help you get going and as always you can join the discussion on the
map designer email list. What we want for New Years is to get to play your custom maps in Left 4 Dead 2.
For the best user experience and to take advantage of the new map and nav mesh formats, Left 4 Dead 1 Map Makers will want to compile Left 4 Dead 2 specific versions of their map in the new tool.
Happy Holidays,
The Left 4 Dead 2 Team

During the production of a game, a lot of concept art gets drawn up, redrawn, thrown away, cursed at, and, occasionally, even used. There's a mountain of this stuff fluttering around the Valve offices, and while the non-artists among us might not know much (anything) about art, we hope we're not embarrassing our artists by saying it looks pretty kickass. So we grabbed some of it off the nearest pile and made it into desktop wallpaper:

When it came time to photograph the box art of L4D1, our art staff had three goals. One, there should be a hand in it somehow. Two, the hand should have a thumb bitten off, so customers would look at the four fingers remaining on the hand and think, "Hey, four." Three, under no circumstances would we use Photoshop. L4D is a visceral experience, and its box art deserved the same approach. Valve artist and L4D1 hand model Andrea Wicklund was more than happy to help.

Survival Mode pits your team against never ending waves of infected. Sounds simple. Just trap the survivors in a small part of a map, unleash the hordes, and record the longest time. Survival Mode, which will be released next week, is actually a bit more than that.

Aesthetics, fiction and gameplay: these are three criteria that we always consider when employing a new art direction for a game. With a game as dark as Left 4 Dead, this meant having to figure out a lot of new ways to use the absence of light to our advantage.

Because Left 4 Dead is a new property for us, we wanted to provide some basic player training prior to the start of the game. Traditional in-game training mechanics didn't make sense for Left 4 Dead, because they would take away from the sense that players had been immediately dropped into a very real, very dire zombie apocalypse.
