Earth

This article is a stub. Please help the Doom Wiki by expanding it.

Earth is the third planet in the Solar System and the homeworld of the human race. It is the primary setting for Doom II and Doom Eternal, and is referenced heavily in Doom 3 and Doom (2016). It also briefly appears in the live-action films Doom and Doom: Annihilation.

Doom/Thy Flesh Consumed[]

Ending image in Doom. — Ending image in *Doom*.

Doom's original ending and follow up Thy Flesh Consumed take place upon Doomguy's return to Earth via a teleporter (at the end of Inferno), where he discovers the remains of his pet rabbit Daisy outside of his home city that is now overrun by demons. He fights his way through his hometown, to stop the initial invasion by Hell, setting up Earth's total invasion in Doom II.^[1]

Sigil/Sigil II[]

In this 'unofficial sequel' (later officially published in Doom + Doom II) Episoded 4 Thy Flesh Consumed is reimagined as not Earth, but a mirrored earth that is part of the Stygian Abyss, at the end after defeating the Spider Mastermind (E4M8), the gamekeeper Baphomet glitches the portal back to Earth, sending him deeper into the stygian pocket.

In Sigil II Satan has sent Doomguy deeper into the bowels of hell... where he faces off against the harbingers of Satan, where he finally can return to Earth to become it's savior.

After killing the Spiderdemon at the end of Thy Flesh Consumed, your next stop is Earth - you must save it from hellspawn that is causing unimaginable carnage. But Baphomet glitched the final teleporter with his hidden sigil whose eldritch power brings you to even darker shores of Hell. You must fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth's savior. Sigil fits in between the timelines of DOOM (1993) and DOOM II.

Note: There are two versions of Sigil I prologue story/description. The first one (paraphrased from back of the box and John Romero) the version that appears in the Doom + Doom II collection states that he is in Hell, and finding a portal back to earth. This is also confirmed in a related Daisy death certificate produced by John Romero that calls this realm the "Stygian Abyss" ("Daisy, The Pet Rabbit was sent into Stygian Abyss... Cause of Death: Demonic Guillotine... Location of Death: Episode 3, Inferno"). The second version appears in the game's readmes/documentation which implies hes somewhere else not in hell possibly could be original earth, or an alternate earth, or could be somewhere else (terraformed mars?), and was 'brought back to hell' at the end of E4M8.

After killing the Spiderdemon at the end of E4M8 (Unto the Cruel), your next stop is Earth — you must save it from hellspawn that is causing unimaginable carnage. But Baphomet glitched the final teleporter with his hidden sigil whose eldritch power brings you to even darker shores of Hell. You fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth’s savior.

-John Romero

Baphomet was only doing Satan's bidding by placing a powerful sigil in the teleporter out of E4M8 to bring you back to Hell. Somehow they didn't understand that you're the reason they failed in the first place.

It's time to trash the place with your arsenal, get out of Hell, and back to Earth to face the more advanced demons that were sent ahead.

Lock and load. Rip and tear.^[2]

Upon breaching the pentagram of invulnerability in the final moments of SIGIL, Episode Five, you find yourself not on a victorious journey back to save Earth, but caught in Baphomet's cunning snare, catapulted into a new, grotesque domain of relentless torment, unending demon hordes, and an onslaught of heavy metal mayhem!^[3]

Doom II[]

Earth is where most of Doom II takes place. Immediately following the events of the previous game, Earth has been invaded by the forces of Hell and a large proportion of the human population are killed. The player, who has traveled back to Earth by drop pod after the Hell invasion of Mars, battles the demon forces in order to allow the survivors to escape the ruined planet. At the end of the game, the invasion is defeated, and the survivors are left to presumably resettle and start rebuilding the planet.

Doom 2 TOSG (Prima)[]

In this guide it follows the ending of Doom, after returning to earth using the teleporter from Hell, the player overlooks flaming city. He travels to spade port to help safe survivors.

Plutonia Experiment[]

Doom 3[]

In Doom 3, Earth is never seen in the game itself, but is mentioned multiple times as being the center of human civilization, as well as being the ultimate target of Dr. Malcolm Betruger and the demon forces. It is hinted that the ancient Martians may have fled to Earth after the devastating war with Hell, and that humans may be their descendants. It is also mentioned that at some point in the past, the demons were actually on Earth but were defeated and driven into Hell, hence their desire to return and retake the planet.

Doom RPG[]

While not shown the backstory is that the Doom Marine returns to Mars from Earth after the events of Doom, Doom II and Doom 3 to fight the forces of Hell once again.

Doom II RPG[]

The middle of Doom II RPG is set on Earth, in the East Coast UAC Facility. The three main characters of the game are teleported there after working their way through the Moon's Lunar Outpost.

Doom (2016)[]

Earth in the 22nd century is heavily populated and prone to energy shortages. Thus the discovery of Argent Energy on Mars was a huge boon, allowing nearly limitless energy potential for humanity. This technological breakthrough was spearheaded by the UAC, a mega-corporation led by Dr. Samuel Hayden to mine Argent Energy as well as research archaeological sites in the dimensions beyond.

Doom Eternal[]

Following the events of Doom (2016), Earth is invaded and overrun by the forces of Hell. Over 60% of the planet has been consumed by the demons and the majority of the human population have been killed in the first month of the Hell invasion, following the catastrophic failure of virtually every man-made system. The remnants of humanity have either fled the planet, or reside in massive fortress cities under the jurisdiction of the Armored Response Coalition.^[4]^[5]

Large portions of Earth's environment and atmosphere are rendered extremely inhospitable due to demonic corruption, as cancerous Hellgrowth infestations accelerated the hostile terraformation of the planet and creating Hell portals for demons to travel to Earth.^[6]^[7] The damage to Earth does not limit itself to the planet's surface — the moon has been partially destroyed, with portions of it forming a ring of debris around Earth.

The Hell invasion soon ended with the deaths of the Hell Priests and defeat of the Icon of Sin at the hands of the Doom Slayer, causing all demons to retreat from Earth. By the events of The Ancient Gods - Part Two Earth has recovered from the invasion, as the planet's environment has returned to a lushest state, and ruined and empty cities are covered in overgrown vegetation. Humanity was left emboldened by the Slayer's triumph over the forces of evil, as the ARC has led resistance efforts in coordinated assaults to purge the remaining demons from Earth.^[8]
