The heart of the storm

I world in which nuclear war has thrown the world into chaos specific parts of the world, having distinct and extreme weather destroying the surrounding land and shifting continents and landmasses. Specific continents like Asia and Africa split due to the extreme weather. Due to the insane amount of radiation animals have mutated, especially insects creating almost fictional monsters The world has divided into Factions adapting to the new world. To survive some people went through radiation exposure in hopes and gaining mutations that may be able to defend them, but due to the fact that it is random people have created electronic limbs to enhance the and advanced weaponry trying to survive. In the face of disaster, you would expect humans to work together to survive but most went to war.
