VG247 are reporting that Valve have finally announced a release date for Left 4 Dead 2's Cold Stream campaign. Now I know what you're thinking, you're thinking "But Tom! Isn't that campaign out already?" To which I reply "How can I hear what you're thinking, am I telepathic now?" But also "Nope, it's just been in beta testing. For a year." Which is a fairly speedy release in Valve time.



Cold Steam has spent the last year in community testing, with Valve gathering data on how the players perform on the map and adjusting it accordingly. But it's technically never been released until now, or rather until July 24th.



Assuming other Valve projects follow this release pattern, we estimate we'll be able to review Dota 2 sometime around 2014. In fact the truth is Half Life: Episode 3 was actually finished in 2009, but Valve feel it needs another six years of testing to be sure they got it right.*

Is it possible to hate streams? I can't imagine anyone being offended by one.

Left 4 Dead 2′s Cold Stream DLC has been through more tests than a guinea pig that just survived a nuclear blast. As well as the new map, the DLC contains Blood Harvest, Crash Course, Dead Air and Death Toll from the first game, but that’s not new news. The fresh meat on this data morsel is the availability of all mutations at all times and Valve promise “other surprises and details” soon. July 24th is the release date. That’s the release date for the DLC, by the way, not the guinea pig. The guinea pig is too uncanny to release into the wild so top scientists have sealed it in a lead box which is currently being dropped into a furnace.

After over a year of public testing, Valve will officially launch Left 4 Dead 2's 'Cold Stream' DLC later this month. It packs versions of original Left 4 Dead campaigns Blood Harvest, Crash Course, Dead Air and Death Toll, as well as the community-made Cold Stream. On top of that, a patch launching alongside will make all of the game-altering mutations available at all times.

The DLC and accompanying patch will launch on July 24, Valve revealed in a blog post. Valve put Cold Stream up for public testing last March, followed by the remaining L4D campaigns (No Mercy had launched before). Now, thanks to the wonders of Valve time, it's finally ready to roll out.

Valve has been rotating mutations weekly since February 2010, with only one available at any time. Their weird and wonderful effects have included turning all enemy infected in Versus into tanks with 'Taaannnkk!,' the infinite ammo M60 madness of 'Gib Fest,' and mode-mashup 'Versus Survival.' When the new patch launches in the 24th, you'll be able to play any of them whenever you want.

While the Cold Stream DLC will be free on PC, Valve will most likely charge on 360.

Maybe we'll all get cameos!Well, this is odd. We’ve known about an upcoming Payday: The Heist-Left 4 Dead crossover for about a month now, and – as is often the case with these things – it materialized earlier today via YouTube’s eyebeaming ethers. “”Have you ever wondered how the Left 4 Dead series began?” the video’s description asked, forcing me to realize that I’ve never actually wondered that. “It started with a heist!” Intrigued, the Internet looked on as Payday’s band of mask-loving hooligans shot its way through a very un-zombified version of Left 4 Dead’s Mercy Hospital. And then the trailer disappeared.

Happily, Eurogamer managed to upload a roll to its own Internet-powered projector machine, so you can still watch the trailer and remember it as it was before its mysterious disappearance. Perhaps Valve and Overkill (now known collectively as Valverkill) stole it. From themselves>. This may just be a heist caper for the ages. I, however, will work tirelessly to get to the bottom of it: Oh look, here’s the answer. It’s just a Left 4 Dead cameo (character and hospital setting) in a Payday map.

Hooray! Sort of, eh?

Community Announcements - the gish
Nightmare
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.
