What’s better than seeing the world? Seeing the world during its post-life crisis – at least, according to Valve. And so, during a recent pow-wow with Kotaku, Valve writer Chet Faliszek confirmed that a smattering of new L4D scenarios are currently making sure their crumbling shacks and snaking paths are undead-accessible, as is the long-awaited L4D SDK.
 
However, as of now, details are sadly few in number. Apparently, Valve wants to “deliver more content you can play at this point,” meaning that the SDK probably won’t arrive with the initial batch of DLC.

On the bright side, the zombpocalypse preparation tool’s first tune-up will add versus mode support to the Dead Air and Death Toll campaigns, allowing you to feast upon your friends’ flesh at all of the game’s fine locales.
 
The Kotaku-Valve chat was recorded on December 15, so Faliszek’s claim that "We should be announcing that before Christmas, what the DLC is,” was obviously derailed.

"The holidays aren't actually so much delaying it as the press guys--[marketing VP] Doug [Lombardi]'s been taking some time. We'll have an announcement shortly, I don't know exactly when,” he continued. We’re guessing that bit’s still valid.
 
As is Valve’s wont, the DLC probably won’t cost any money – though arms and legs haven’t been ruled out just yet.

We’ll make sure to let you know when Lombardi and co. finally raise the curtain on Left 4.1 Dead. Pencil us in for “soonish.”
