Originally slated for a late March release, Valve's upcoming "The Passing" DLC for Left 4 Dead 2 has been delayed to a new "Spring" release period. The add-on brings three of the original game's survivors down south for a meeting with the Left 4 Dead 2 cast, while delivering new single-player, multiplayer and co-operative gameplay.

No official reason was given for the delay, but the news at least came alongside pricing details for the Xbox 360 version – The Passing will cost 560 Microsoft Points ($7) on Microsoft's console, the same as the Left 4 Dead 'Crash Course' DLC, while presumably remaining free on PC. Other new details include players able to wield the new golf club melee weapon or M60 machine gun, and encounter two new enemies: a "Bride" version of The Witch and a Molotov cocktail sporting zombie known as the Fallen Survivor.
