Zombie Mode?

  1. I see a video on youtube.com showing all NPC's turn into zombie. My internet connection is slow so I can't see the full video. Can someone tell me how to enable this mode? Is it needs a patch or somthing of this kind to enable or this is an easter egg? also can it is possible to enable this mode on all levels.

  1. It's an easter egg which involves killing people in a certain manner on the "Death on the Mississippi" mission. MikePenance's guide explains it under the easter eggs section.
