The Left 4 Dead Blog reveals the new weekly mutation for Left 4 Dead 2 as "Follow the Liter," where only one group of cans spawns at a time, so survivors know exactly where to go, except the Infected know exactly where they are going. Valve also announces that last week's vote resulted in an overwhelming victory in favor of making Realism Versus a permanent mode, and next week they will announce when this will happen. They also reveal their new poll question is about rage quitting in Versus mode. The update concludes with word that the developers of the zombie shooter will be playing all weekend on PC and Xbox 360, offering a list of developer player names.
