In an official press release earlier this afternoon, Valve announced the first DLC add-on for Left 4 Dead 2 (L4D2), "The Passing," targeted for an early Spring 2010 release. The Passing "brings the original Left 4 Dead (L4D1) Survivors down south for a meeting with the L4D2 cast, while delivering new single-player, multiplayer and co-operative gameplay for the PC and Xbox 360." Valve stated that players will assume the role of the L4D2 Survivors and merely meet with the L4D1 characters. However, in addition to a new co-operative campaign and arenas for Survival, Versus and Scavenge mode, there will also be a "new co-operative challenge mode of play." Does this mean a 4 + 4 or 4 vs. 4 game mode? No word yet, but let the rumors fly! The Passing will also add a new "uncommon common" zombie class, melee weapon and firearm.
Doug Lombardi, VP of marketing at Valve, is calling The Passing "the most important campaign in the Left 4 Dead story." Only time will tell if it lives up to that.
