Valve have revealed some details for their first DLC pack for Left 4 Dead 2.

Titled; ‘The Passing‘, the new DLC pack will merge the cast of Left 4 Dead 1 with that of Left 4 Dead 2.

The DLC will consist of a new campaign with plenty of new single-player, multiplayer and co-op features thrown in to boot.

Here are the new features as described by Valve.

“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. 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.”

Although no dates or prices have been confirmed, Valve have said that they are targeting an “early spring” launch.
