"We studied what's happened on our planet in the past 200 years in terms of natural disasters, wars, and nuclear catastrophe. We looked at the impact on environments, weather patterns, wildlife, and population. We created our own model and ran it for 15 to 20 years [into the future].
We even presented the model to two meteorologists who specialize in building 'what if' models. They've been working with the US government and military to create these scenarios and see how the US could respond. They really helped us get into the details."
The result was Hope County 2.0. Following Far Cry 5, the world undergoes a period of nuclear winter that lasts six years, the end result being the transformation of major population centers into gigantic deserts. This winter then cedes, bringing forth sun, rain, and a super-bloom, an expanse of plant life that covers everything in living color.
