Nuclear wasteland

"'It's the Wild West. Reborn. Only worse, with no sun-light and only misery to keep you company. And that's if you're lucky and don't fall victim to the New World Order or one of the other gangs running the shitshow...'" After the nuclear devastation that was World War 3, the population on Earth was sparse and its lands had become a nuclear wasteland... nuclear fallout clouded the atmosphere and sunrays no longer touched the ground. Life became... dead. Those who didn't fall during the war, fell victim to the wastelands. Those who didn't lose their life to the wastelands were its victims in other ways:

Depression, constant hunger, violence, mutations...

Mutations
Though confirmed reports of mutations barely reach Lagos -- Earth's only remaining civilized nation -- their existence is definitely more than just a rumor. The full extent is unknown, but it is known that the nuclear fallout has caused severe mutations among those who still live in it... be that man or animal. Some of these mutations are less favorable others, though one of such mutants, Kor, is said to have grown 4 arms and now rules over the nuclear wastelands as something of a deity. Chaos gives rise to opportunity and Kor seized it by creating what he calls the New World Order.

There isn't more information to these stories, just barely enough to warrant them no longer being labeled as mere 'rumors'...

Lagos' government regularly dispatches scavenging parties into the nuclear wastelands in the hopes of finding leftover mechas, exo-suits, AI or some other remains that might give them an edge in their power struggle against the inama.
