I’m slightly late on this so sorry about that.
The exceptionally well done I Hate Mountains campaign for Left 4 Dead has just been updated to 1.2. The major thing about this release is that we’re finally getting the campaign on Left 4 Dead 2. After almost 8 months in development we can finally play the amazing campaign on Left 4 Dead 2, with 1.2 comes some bug fixes for the Left 4 Dead Version. They have noted that there are some bugs they were unable to fix but I’m sure we can forgive them as working with any Source Engine game is always a painful process.
