A L4D2 DLC campaign was announced recently, and the main focus of it is the return of the old survivors. This is great news for the fans who really connected with the original cast. The new campaign is called “The passing”, and it’s set in a small rural town in Georgia, featuring one new uncommon infected, one new melee weapon, one new firearm, and a new co-op mode.

What I’m wondering is how big this expansion will be. You’ve probably heard how each survivor has over one thousand voice lines, so there’s going to be some downloading to do. Also, pricing hasn’t been announced yet, but PC players can expect it to be free.

It appears that either we have a glitched achievement that us impossible to gain or Valve has hidden something for us to find.
