Valve is readying a downloadable content pack for its zombie laden co-op shooter Left 4 Dead 2, one which will feature a meet up between the new cast and the original survivors from  the first game: Bill, Francis, Zoey and Louis.

Dubbed “The Passing,” this add-on is targeted for release in “early 2010″ and takes place after the Dead Center campaign of L4D2, set in a small town in rural Georgia. More details courtesy of Valve ensue:

In addition to the new co-operative campaign and associated narrative, “The Passing” will include new arenas for Survival, Versus and Scavenge mode and introduce a new co-operative challenge mode of play. The Passing will also include a new “uncommon common” zombie class, melee weapon, and firearm.

“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,” said Doug Lombardi, VP of marketing at Valve. “It will also be a huge offering of new gameplay content, with something new for every game mode plus a new uncommon common and weaponry.”

Pricing was not revealed as part of the announcement but Valve did note that details on that front would come as the launch date approaches.
