Apparently the first batch of Left 4 Dead 2 DLC is going to feature the survivors from the original game. The players will meet up with them during the new campaign level called ‘The Passing’.

I’m quite looking forward to this as I’ve been intrigued by the rumours that the first survivors are in fact carriers of the virus.
Unfortunately we’ll all have to wait until Spring 2010 to find out if that’s true.
