I just read this article over at Kotaku which is talking about the new content coming for Left 4 Dead 2. As previously stated, the DLC is known as The Passing in which the old survivors meet the new survivors and they all go out to dinner together. Actually, there isn’t much mentioned except that the survivors meet in the third mission of the DLC whereby they kill a lot of zombies.
Once the DLC is released, Valve also plans to release a digital comic which purports to give some explanation of the character’s back story, giving you further motivations to smash Ellis in the face with a shotgun.
Then, believe it or not, another round DLC is slated to be released for only the first game that will tell the story of how the original survivors make it to The Passing. Valve estimates that this should all be in our hands in the next few months but knowing how those mad scientists work, I think we can expect a mid 2012 delivery.
