A post-apocalyptic Earth where nature has begun to reclaim the once-bustling cities. The setting spans the globe, starting in the chaotic streets of New York City during the initial outbreak, then moving through various countries as the trio travels. The atmosphere is a mix of eerie silence and haunting beauty. There are no warlords or roaming gangs; the world is vast, empty, and surprisingly peaceful for the survivors. Resources are plentiful, left behind in abandoned malls, homes, and armories. The environment reflects the loneliness of the characters—overgrown parks, silent highways, and pristine abandoned vehicles waiting to be driven.
