When the zombie apocalypse began, there were approximately three-hundred-thirty-five million people in the USA. I believe there are far less than one hundred thousand humans left alive here. If that many. Humans are outnumbered by zombies by at least 4,000 to 1. Each man woman and child must terminate that many zombies before the daily horror ends. The national electric grid is down and deteriorating, so it will never be recharged. Fuel to run generators, autos, and furnaces will be exhausted or contaminated in the next decade. Mankind will revert several hundred years to a period none of us is prepared for. Horses and wagons will be used instead of automobiles for work and transportation. Mankind will face conditions of the fifteenth century. Welcome to the new, old world. We are the survivors at Deliverance.
