Doom (2016 video game)/Setting

• Death World: Hell itself in more than just the obvious ways. Not only do people become reanimated as zombies and cannibalized into raw materials for producing whatever Hell needs, even the lesser demons wind up becoming corpses fed into their own meat grinders and greater demons to sustain them. It even goes so far as to absorb parts of other dimensions and leave the remains of whatever they incorporated lifeless husk versions of their former selves.
• Fire and Brimstone Hell: Portions of Hell do indeed resemble this, but not everywhere does.
