Toxic plastic trash Souls with random fires everywhere, dead trees and smogged out skies that occasionally reveal a sun that burns your flesh. Occasionally, a distant plane will fall, burning out of the sky, leading to loot. Toppled skyscrapers are in the distance here and there with some of it going into the mud due to nature's overall death. Litter the place with a few toxic rivers full of garbage, with burning smokestacks in the distance among thousands of miles of shack-houses.

No guns, because by this time everyone will have willingly lent over their 2nd Amendment rights, just lead pipes full of screws and Stop Signs replaced with giant buzzsaws. Throwables would be molotovs and grenades made of leftover fireworks.

The 'lord souls' if you'd like to call them that, would essentially range from gang lords for mid-bosses leading to capitalist overlords by way of metroidvania-style exploration of their dens of pure malice and spite.

Craftable items would be bolstered by finding various Anarchist Cookbooks.
