Left 4 Dead DLC, SDK Announced 66
Today Valve announced plans for Left 4 Dead's first DLC, called The L4D Survival Pack. It will include a new game mode and two campaigns for Versus mode. The new content is coming to both the PC and Xbox 360 versions of the game (a PS3 port to the base game still seems unlikely). The press release goes on to say, "In addition, for PC gamers and aspiring developers, the first Left 4 Dead release for the Source Software Development Kit (Source SDK) will allow the creation of custom Left 4 Dead campaigns that will be discoverable via L4D's matchmaking system. The SDK update is also due for release this spring, and is free of charge to all owners of L4D on the PC." The Opposable Thumbs blog also reports on a way to play Left 4 Dead in 3D.
