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. But what we have heard so far from Valve, the old survivors will be playable, but this may change during the process of The Passing.
