The Passing

"The Passing will become the most important campaign in the Left 4 Dead story, as all the Survivors are being called together in one campaign."

- Doug Lombardi

The Passing is an upcoming DLC for Left 4 Dead 2 which includes a new campaign and "a new co-operative challenge mode of play.". The Add-on also includes new weapons, one melee and one firearm, and a new Uncommon Infected. The new campaign takes place between Dead Center and Dark Carnival in a rural town in Georgia. It will also feature a meet up between the Left 4 Dead 2 survivors and the original survivors. The campaign will be playable in all the game modes including the new game mode. Valve hasn't announced pricing details yet, but they do have a target release window: "early spring" for both the PC and Xbox 360 versions.

Because the campaign will feature a meet between the old survivors and new survivors, fans thought it would include 8 versus 8 multiplayer. However, a programmer at Valve has stated that it will not be a reality. He hinted 8 player co-op was a possibility.

Many fans from many Left 4 Dead communities are debating how the Survivors from Left 4 Dead 2 will meet the original Survivors. Many fans are saying that the Survivors will meet on the other side of a door, similar to the Church Guy, or they will collide paths somewhere, or be heard on the radio, and not seen anywhere in the entire campaign.
