Crash Course DLC is here! Find out what happens to Bill, Zoey, Louis, and Francis after their rooftop helicopter rescue in the No Mercy campaign. To celebrate the release of our second DLC for Left 4 Dead, we are offering Left 4 Dead for 50% off until Oct 2nd.

Next Stop: Penny Arcade Expo

We will be unveiling Dark Carnival at the Penny Arcade Expo in Seattle September 4-6.

Dark Carnival is the third of five campaigns we have revealed. It is the second campaign of the game and picks up after you have escaped from Savannah.

First Stop: Comic Con

During the San Diego Comic Con gamers had an opportunity to visit us in our Left 4 Dead 2 room and try out two L4D2 levels from the "Swamp Fever" campaign. The response was overwhelming, with lines going out the door well before we opened. Throughout the four days that the demo was made available, there was never an empty seat.

We're pretty excited about this next Left 4 Dead update, and we hope you will be as well. Since the Left 4 Dead Authoring Tools Beta was released several weeks ago, mod authors have been cooking with gas, so to speak. The ranks of dedicated community members working hard to create new content have been swelling, and a very hungry horde awaits...

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.

We've just announced that Left 4 Dead 2 is coming later this year! It's a much larger game than the original, and features new co-op and versus campaigns, all-new Survivors, boss zombies, weapons, and items, as well as melee combat. Check out the teaser trailer, and watch this space for more news in the coming days.

It's been an interesting week for us here on the Left 4 Dead team. This Monday, for instance, somebody accidentally told Robin Walker he had the power to fire people. In other interesting news, the Left 4 Dead team has all been fired.

The 27th Annual Golden Joystick Awards are now accepting votes for your favorite game of the year. Now, we'd of course never for a second want to sway your vote and suggest you follow this link and vote for Left 4 Dead. We're above that sort of thing.

Today we are opening the beta of the Left 4 Dead Authoring Tools to the public. It is available as a free download for all owners of the PC version of Left 4 Dead, and can be found under the "Tools" tab in Steam.
