DOOM Eternal: Future Hell Exploration

Going all the way back to the very early days of pre production on DOOM Eternal around 2015 I had the pleasure to explore what a "future hell" could look like. Many of these being some sort of advanced metropolis in the demon infested world of hell. The idea eventually evolved into the Hell Capital City Immora.
