Updates to Left 4 Dead 2 have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

Encore mutation: Taannkk!

Dead Center - The Mall
  • Survivors can no longer bypass the storefront mini-finale.

Dark Carnival - The Barns
  • Survivors can no longer bypass the barn interiors.

The Parish - The Waterfront
  • Removed the Survivor zombie-jump exploit in the first alley.

The Parish - The Quarter
  • Survivors prevented from using short cut over the top of the fence.

Cold Stream
  • Various bug and exploit fixes for the first 3 maps.
  • Added survivor respawn closets some temporary while we work on the maps.
  • Added navigational aids to maps.
  • Changed the first maps ending as an experiment please give feedback!
  • Added alternate route around boat mast please give feedback.

To help with public testing, we fixed more bugs and exploits than we normally would on maps that are still in a transitional state. We are holding off on many changes to the finale right now as that map will change the most.
