Valve have released a bit more information on the upcoming DLC pack for Left 4 Dead 2, called The Passing. The list, published on the game's blog, kind of speaks for itself:
* A Wicked Witch Bride!
* A Gargantuan M60!
* A Slashing Golf Club!
* And Introducing The Fallen Survivor!
* Meet 3 Left 4 Dead 1 Survivors!
* New Game Modes!
About the "new game modes"-point, Valve writes:
"Was that a typo? Game Modes? Didn't we mean Game MODE? Did we mean to include that 'S'?!?!?" YES WE DID!"
Sounds like The Passing, which will have the new survivors meet the new survivors (perhaps voting someone off the island?), is getting pretty meaty. Valve is also taking the opportunity to sell Left 4 Dead 2 for half the price on Steam for a few days.
