The apocalypse happened fast and angry, within a day, our population was cut down to 250 million. The cities were the worst, any city with over 1 million residents suffered from the attack of a monster. New York fell to the giants, Boston fell to a clan of dragons and LA was burned to the ground by a wave of undead. Across the seas, Beijing fell to 5 tribes of orcs, Shanghai was overrun by nests of giant spiders and Japan was wiped out by nests of harpies. I was lucky, I survived.
