Revelation 20:13 - "And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works."
On February 28th 2008, the dead began to rise, and with them came monsters from hell - Satan's own minions - the Overminds. The zombies, known as Lessers, were mindless and hungry entities. If it had been only them, perhaps humans could have stood a chance. But the Overminds with their powerful servants known as Reavers were able to control the flow of Lessers. Even though the zombie's bite is not infectious, their population is controlled by the Overminds.
People fled major cities and governments fell to the devious creatures. Satan had broken the human race. Mini communities formed. The best known was an underground compound known as Safe Haven, but political and civil unrest brought about its downfall in the summer of 2013.
Eventually, Abital made its mark on the map around 2011. While supposedly a human town, corruption runs deep, and even the Overminds indirectly control it. A deal with the devil keeps its walls from crumbling.
Most people are on their own, surviving and hiding from the powerful creatures that want to see nothing but humanity's destruction. Because the human race is so broken, the new inhabitants of this new earth have carved out their own existence and rumors have sparked about their own devil's town.
