Current DLC in Progress: The Passing

As you have heard since December, Valve announces their first add-on for their cooperative zombie thriller, Left 4 Dead 2. This add-on is dubbed "The Passing" where players assume the roles as the Left 4 Dead 2 survivors as they meet the original Left 4 Dead 1 survivors. Unfortunately the original cast is unplayable is this campaign. The survivors will meet face to face at the beginning of the campaign and then again at the finale. The campaign takes place after Dead Center and before Dark Carnival. Set in a small rural town in Georgia, "The Passing" is a 3 map campaign. This campaign will feature
a new campaign, melee weapon, uncommon common infected, game mode, and firearm.

New Campaign: The Passing
New Melee Weapon: The Golf Club

New Uncommon Common Infected: The Fallen Survivor
New Game Mode: [UNCONFIRMED]
