We're gonna change things, in this alternate universe, the world has gone mad, the water has reduced to nothing, and everywhere becomes a wasteland, a desert, limited green places, become a War Boy by Immortan Joe, a Buzzard, or a Roadkill, each have their own purpose. Or become a lone survivor, or a team, or even meet up with Max Rockatansky. The choice is yours, but be aware, there are limited water, and food, and any enemy can come from anywhere. Many species can be used, humanoid ones.
