What I’m really missing is a reason for the players (and the humans) to survive in this cataclysmic world.
I don’t mean “killing a zombie from the seventh dimension with a black hole cannon” but a simple reason to live there. You’re survivor but what’s next? I’ve killed thousend of creatures; I’m close to unbeatable because I have everything, but why should I wish to live longer? In the current game you simple live 'til your death (I don’t know if age is part of the game) and after that the human civilization is wiped out forever.
Where are the surviving children? Are there plans in secured areas to build up a new human civilization ? I often stop the game at a point because I don’t know what to do next : Exploring the 20th lab? Running through the 12th city? Killing the 5.000 th zombie?
I hope you understand what I mean. I can’t decribe it better (english isn’t my native language). Are there areas out the where the humans are unaffacted? Is the cataclysm global? Can you leave the infected continent to find another land where other non infected people live? I think about planes on airports. Maybe even a new profession : pilot.
