Purgatory
The UAC facilities of Mars and Earth, twisted gateways where Hell invades reality.
In the Doom saga, there is no officially named dimension called 'Purgatory.' Instead, the Slayer's journey centers on Earth and Mars, specifically within UAC facilities that have been breached by Hell. These industrial complexes serve as the primary gateways where demonic forces invade our reality, transforming familiar corporate architecture into nightmarish battlefields rather than existing as a separate theological transit zone.

Lore & Background
Contrary to theological concepts of a waiting room for souls, the Doom universe features no such dimension. The conflict unfolds primarily on Mars and within UAC outposts that have been torn open by portals from Hell. These facilities act as the invasion front lines, where the Slayer awakens—most notably in 2016 on Phobos—and must fight through corrupted industrial labyrinths to seal the rifts. The 'twisted' environments are not a separate realm but rather human technology and architecture warped by demonic energy, serving as the staging ground for Hell's assault on humanity.
In Their Own Story
The air tasted of copper and old ash as the Slayer stepped through the rift, his boots crunching on a floor that felt uncomfortably like the metal grating of a UAC facility. Above, the sky was a bruised purple, swirling with clouds that looked suspiciously like screaming faces. He raised his Super Shotgun, the weight familiar and comforting against the chaos surrounding him. To his left, a canyon of rusted machinery stretched into infinity; to his right, a bridge made of bone connected two floating islands of obsidian. The silence was broken only by the wet thud of something heavy landing nearby. An Imp snarled, its eyes glowing with malice, before the first shot rang out, echoing off the twisted spires of this forgotten waiting room.
Reader's Guide
Purgatory serves as the primary bridge between the safety of Earth and the abyssal depths of Hell in the modern Doom narrative. It is a dimension where the laws of reality are bent to serve demonic purposes, often appearing as corrupted versions of human technology or ancient ruins. Its role in the story is pivotal: it acts as the staging ground for invasions and the testing field for new demonic breeds. The Slayer must navigate its treacherous landscapes, fighting through waves of enemies that range from basic grunts to elite warriors, all while uncovering the secrets of how Hell intends to breach Earth. This realm matters because it represents the thinning veil between worlds. Every step taken in Purgatory is a step closer to stopping the apocalypse, making it the front line where humanity's last hope battles for survival against impossible odds.
