Yeah, I typed this up when I was using a on-screen keyboard, so I didnt really add details. The developers said : "There will never be a -before the outbreak- added, nor will it tell you how." But by waking up as the apocolypse is starting, breaks no rules. If you have watched dawn of the dead, and how the zombie outbreak started then I imagine it would be similiar. Neighbors, slaughtering other out of fear, of the unknown you can either try to break up fights, start some, or just run. The NPCs could refer to that day as "Day Zero". And if you started fights, or broke them up could help them decide what kind of person; leader; you are. Every ounce or respect, for some NPCs could be from that day. I think that would be very fun, if I do say so myself.
