The release is a mix of fixes, tweaks, enhancements and features. PC players are the spoiled one this time, as the update will be applied automatically via Valve’s Steam.

In the mean time, Xbox 360 players will have to sit down and wait for their turn. The company promised that the console version of the patch will become available in the coming weeks.

– Fixed Survivors being able to climb surfaces marked for versus infected only
