We should be adding these into the featured custom campaign list.
There were 6,541,389 incidents of friendly fire.
98% of the game sessions had zero players kicked during the game.

All in all, a pretty good day for a game that was released 969 days ago.

Competitive Versus Mutation
Confogl is a set of rules for competitive L4D2 Versus that standardizes many of the elements and changes item and weapon distribution. In general it tips the balance a bit more towards the Infected.
ProdigySim, the creator of this Mutation, has made another update based on community feedback.
- Single hunting rifle given out in saferoom on non-intro maps, other hunting rifles removed.
- Spitters removed from spawn rotation while Tank is in play.
- Natural hordes are removed.
- Hunting Rifle reserve ammo increased by 70 bullets.
- Extra witches spawning on round 2 of Hard Rain chapter 2 are removed.
- Item Limits and limiting algorithm tweaked.
This week would be a good time to test this mutation. We are hoping these final tweaks are good and we will make this the version we include in the big update. So please – if you can – play it this week. Any guesses on how many unique players we can get to give it a try this week?
Cold Stream Release
In case you just read the in-game blog – good news. We have a release date for Cold Stream! The entire DLC consisting of Blood Harvest, Crash Course, Cold Stream, Dead Air, and Death Toll, will be released on July 24th.
With the update going out at the same time (also for the PC), all of the mutations will be available at all times. This will allow players to choose to match into games playing Taannkk!, Gib Fest, or even a user created mutation like Confogl.
For PC players we also updated the featured community campaign to Blood Tracks.
Grab it from here
and you can choose to play it on Official Dedicated since we have updated our servers with it.

After months *cough*year*cough* of play testing not just the Cold Stream campaign on the PC but the entire DLC consisting of Blood Harvest, Crash Course, Cold Stream, Dead Air, and Death Toll, we are ready to release on the Xbox 360.
The date will be July 24th. There are some other surprises and details we will give you later but for now we just want to confirm an often requested feature. With the update going out at the same time (also for the PC), all of the mutations will be available at all times. This will allow players to choose to match into games playing Taannkk!, Gib Fest, or even a user created mutation like Confogl.
Stay tuned for more information in the coming weeks as we get ready to launch.

You’ll never see them coming
This Survival Mutation was inspired by Karma Jockey. There are commons, plenty of beefed up Specials, no glows, and lots and lots of fog. If you like to be scared by things that jump out at you from the night, this one is for you.
What do Zombies Think?
While cleaning/moving our offices around (all our desks at Valve are on wheels so we can have desk races), we discovered this old, long ago used Zombie decision making tree. It was created before our session with Mike Patton to record the common zombie sounds. While it is near indecipherable gibberish thanks to bad penmanship, it shows not at an AI level how a zombie behaves but all the speech opportunities and transitions.
Our favorite is the top. Lay Down? Nope. Want to vomit? Sure.
