Knee-Deep in the Dead

 * Doomguy is a dishonorably discharged soldier-turned-security guard in a Union Aerospace Corporation prison on Mars.
 * Shortly after Doomguy arrival, UAC scientists begin turning into zombies.
 * Doomguy tries to help as many survivors as possible.
 * Doomguy defeats two Barons of Hell...only to be transported to Hell.

The Shores of Hell

 * Flashback: In court, Doomguy is convicted of murdering his commanding officer after refusing to destroy a terrorist base, resulting in his dishonorable discharge and transfer to UAC.
 * After defeating the barons that were protecting the main gateway on Phobos and gaining access to the anomaly, Doomguy finds himself caught in an ambush. After noting the stench of rotten meat, he realizes that his surroundings seem to resemble the lost Deimos moon base which earlier disappeared from the sky above Mars just before the demonic invasion began. Progressing into the base facility by facility, he finds that it too has been overrun by the forces of Hell, but also that its environment has become twisted and corrupted - wood, marble and stone inexplicably replace electronics, flesh hangs in sheets over walls, lava and blood flow and gather in pools, thorny vines overgrow large portions of the base, and various demonic artifacts and paraphernalia litter the corridors.
 * Doomguy meets more fierce resistance, in particular from enemies that were not encountered on the Phobos base, including the lost soul and cacodemon.
 * Barons of Hell are now regular enemies. Balancing the equation somewhat is Doomguy's timely discovery of the plasma rifle, a UAC-developed energy weapon with a high rate of fire and equally impressive damage output.
 * In the end, Doomguy faces the almighty cyberdemon lord who rules over the lost base from the newly constructed Tower of Babel.
 * Upon his victory in battle, Doomguy learns the terrible truth: Deimos now floats above Hell itself. Determined to trace the invasion to its ultimate source, he then rappels down to the surface of Hell to continue his battle.

Inferno

 * Flashback: Doomguy is part of a recon team sent to annihilate a terrorist base. The commanding officer orders Doomguy to launch an air strike that'll destroy the base; however, upon closer inspection, Doomguy discovers hostages in the base and cannot bring himself to doing it. His CO, however, does not care about the hostages ("a few lives to save millions") as he pushes Doomguy aside and launches the air strike himself, destroying the base and killing everyone inside...including the hostages. Horrified and outraged, Doomguy snaps and attacks his CO, beating him to death. Due to lack of found hostage bodies, Doomguy is arrested for treason.
 * Having defeated the Cyberdemon lord who ruled over the lost Deimos moon base, Doomguy learns that the facility has somehow been teleported to Hell itself and used as the gateway enabling the demons' invasion of the Martian facilities.
 * Determined to press on and learn the true source of the invasion, Doomguy must fight through the twisted reality of perdition itself. As on Deimos, the environment itself is deadly - volcanic plains, jagged rock, and barren scorching wastelands sprawl before him, punctuated only by looming, decrepit labyrinths dedicated to the worship of evil and the torment of the damned.
 * Eventually reaching the heart of Hell itself, its capital city of Dis, Doomguy confronts the mechanized abomination which masterminded the invasion plot: the Spider Mastermind. Using his newly discovered BFG9000, he leaves the creature nothing more than a charred wreck of tangled metal and splattered brain matter.
 * A portal opens, revealing the green fields of Earth. Overjoyed, Doomguy steps through to return home, only to find that everything is not as it should be...

Thy Flesh Consumed

 * This volume chronicles the Doomguy's battles against the legions of demons that the Spider Mastermind had sent through the doorway between Hell and Earth, the very same gateway that the player had earlier used to return to his home planet.
 * Ultimately, though Doomguy is victorious, inflicting heavy losses on the invaders and avenging the death of his pet rabbit Daisy, it turns out to be an empty victory as the demons have already overrun all the major cities.

SIGIL

 * After killing the Spider Master, Doomguy steps into a teleporter; however, Baphomet glitched the teleporter with his hidden sigil, which brings Doomguy to the dark shores of Hell.
 * Doomguy has to fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth's savior.
 * Ultimately, Doomguy is victorious as he defeats the Spider Mastermind and Cyberdemon, finally reaching Earth...

Worlds on Fire

 * ...NOT!!!
 * It turns out another digil has glitched the teleporter into a possibly even BIGGER Hell.
 * Fortunately, Doomguy fights off the demons and finally reaches Earth (for REAL this time).

Hell on Earth

 * After defeating the Spider Mastermind, Doomguy finds a portal to Earth opened by demons.
 * After returning to Earth, Doomguy finds that it has also been invaded by the demons, who have killed billions of people.
 * The humans who survived the attack have developed a plan to build massive spaceships which will carry the remaining survivors into space. Unfortunately, Earth's only ground spaceport has been taken over by the demons, who placed a barrier over it, preventing any ships from leaving.
 * Doomguy battles hordes of demons and is able to deactivate the force field, allowing the remaining humans to escape.
 * Once all the survivors have escaped Earth, Doomguy is the only human left on the planet.
 * Just as he sits down to await death, knowing that he saved humanity, Doomguy then receives an off-planet transmission from the survivors in orbit, who have managed to find out where the armies of Hell are coming from. The message reveals that the demonic base is in the center of Doomguy's own hometown. He then fights through the city until he reaches the base but sees there is no way to stop the invasion on that side. He decides to step into the portal to try deactivating it from the other side, entering Hell.
 * After fighting through the hordes of Hell, Doomguy reaches the location of the biggest demon he has ever seen, called the Icon of Sin (Baphomet). He kills the Icon of Sin by firing rockets into its exposed brain. Its death causes devastation on Hell, and the portal to Earth is sealed.
 * Doomguy wonders where evil people will go when they die now that Hell has been destroyed and reflects that rebuilding the world will be more fun than saving it as he begins his journey back home.

Infernal Sky

 * Shortly after returning to Earth, Doomguy passes out and falls into a coma.
 * In his coma, Doomguy has a strange dream fighting demons.
 * Doomguy recovers from his coma and returns to helping rebuild Earth.

No Rest for the Living

 * Doomguy is invited to an amusement park.
 * It turns out the amusement park is a trap set up by Hell.
 * Doomguy destroys the demons once again and returns home.

TNT — Evilution

 * The UAC are once again intent on developing and experimenting with dimensional gateway technology. They set up a base on one of the moons of Jupiter, with a solid detachment of space marines for protection.
 * The marines do their job well; when the first experimental gateway is opened, they annihilate the forces of Hell.
 * Research continues with more confidence and all security measures turned at the gateway.
 * A few months later, the yearly supply ship comes ahead of schedule, and looks strange and unusually big on the radar.
 * The lax radar operators decide that there is nothing to worry about.
 * The personnel of the base go out to behold the terrible truth: it is a spaceship from Hell, built out of steel, stone, flesh, bone and corruption.
 * The ship's enormous gates open to unleash a rain of demons on the base. Quickly, the entire facility is overrun, and everyone is slain or zombified.
 * Doomguy has been away on a walk at that time and thus escapes death or zombification. After being attacked by an imp, he rushes back to the base where he sees the demonic spaceship still hovering above it and realizes what has happened. He then swears that he will avenge his slain troops and sets out to kill as many demons as possible.
 * In the end, Doomguy defeats the Icon of Sin and the game describes "something rumbles in the distance. A blue light glows within the ruined skull of the demon-spitter."

The Plutonia Experiment

 * After Hell's catastrophic invasion of Earth, the global governments decide to take measures against any possible future invasion, knowing that the powers of Hell still remained strong.
 * The UAC is refounded under completely new management (the old trustees and stockholders were all dead anyway) and aims at developing tools that would prevent demonic invasions.
 * The scientists start working on a device known as the Quantum Accelerator that is intended to close invasion Gates and stop possible invasions. The experiments are carried out in a secret research complex, with a stationed detachment of marines.
 * The work seems to be going well but the creatures from Outside have their attention drawn towards the new research.
 * A Gate opens in the heart of the complex and unnatural horrors pour out.
 * The Quantum Accelerator performs superbly: the Gate is quickly closed and the invasion is stopped.
 * Research continues more boldly.
 * On the next day, a ring of 7 Gates opens and an even greater invasion begins.
 * For one hour the Quantum Accelerators manage to close 6 of the Gates, but the Hellish army has become too numerous and too strong.
 * The complex is overrun.
 * Everyone is slain, or zombified.
 * The last Gate of Hell remains open, guarded by a Gatekeeper: a powerful, enormous and ancient demon that has the power to open Dimensional Gates and control or protect them.
 * The government, frantic that the Quantum Accelerator will be destroyed or used against humanity, orders all marines to the site at once.
 * Doomguy was on leave at the beach. He was also closest to the site and gets there first. There he discovers that there is much demonic activity (howling, chanting, machine sounds) within the complex; the Gatekeeper is obviously working on something, and his work would soon reach some awful climax. He also realizes that when the marines arrive, they would not be able to penetrate the heavily infested complex, despite the firepower and support they will have.
 * Doomguy enters the complex and stops the Gatekeeper alone.

Absolution

 * A planetary policy is established to quarantine the U.A.C. research installations with apocalyptic levels of radiation.
 * For years, the installations stood motionless and abandoned, until a long-forgotten satellite monitoring one of the installations, barely functioning due to years of being subjected to high levels of radiation, sends a message back to Earth.
 * The message indicates that a single entity, with vast rejuvenation powers and masked by the extreme radiation levels, escaped detection in its crippled state. This entity systematically altered decaying dead carnage back into corrupted living tissue, resurrecting the demons.
 * As the only experienced survivor, Doomguy is sent in alone to exterminate them. Later, he realizes the demons had planned for this, after he unknowingly allowed himself to be lured back into Hell.
 * The demons are unable to defeat him, and with the Unmaker, he eventually battles and kills the Mother Demon.
 * Doomguy, no longer capable of having a normal life following his encounters with Hell's forces, decides to remain in Hell forever to ensure no demon ever rises again.

The Lost Levels

 * Mother Demon is revealed to have a sister called the "Resurrector". It banishes Doomguy back onto Phobos, forcing him to fight his way back to Hell to stop the Demons.
 * Afterwards, Doomguy returns to Hell to fight off the invading monsters for all eternity.

Maelstrom

 * UAC board member Elliott Swann, his bodyguard Jack Campbell, and a recently transferred John Kane arrive at Mars City, the main access to the UAC's Mars base.
 * Sent to investigate multiple incidents involving the Delta Complex, Swann has a tense meeting with facility director Dr. Malcolm Betruger while Kane reports to Master Sergeant Thomas Kelly for orders.
 * Kelly orders Kane to find a scientist from the Delta Labs who has gone missing. Kane finds the scientist in a decommissioned communications facility, where he is frantically trying to send a warning to the UAC on Earth about Betruger's teleportation experiments. However, as he tries to explain the situation to Kane, another teleportation test takes place but loses containment, at which point the entire Mars base is swept with a shockwave.
 * The forces of Hell invade through the teleporter's portal and transform most of the base's personnel into zombies.
 * Now forced to fend off attacks from zombified base personnel and demons from Hell, Kane returns to Mars City, where Kelly gives him orders to link up with another squad of marines and get a transmission card containing a distress call to the main communications facility to call for reinforcements.
 * As Kane progresses through the base, he learns that Swann and Campbell have survived, and are also en route to the communications facility to prevent any messages being sent in order to contain the situation on Mars.
 * The marine squad is ambushed by demons and slaughtered in the EnPro Plant, and although Kane recovers the transmission card, he is too late to prevent the bulk of equipment at the communications facility being destroyed by Campbell. However, Kelly directs Kane to a backup system, where Kane is given the choice of whether to obey Kelly's orders to send for reinforcements or accept Swann's argument to keep Mars isolated until the nature of the invasion is understood, so as not to endanger Earth. Kane is told to go to the Delta Labs by Kelly or Swann, depending on whether the transmission is sent or not.
 * On the way to the Delta Labs, Kane is contacted by Betruger, who is now shown to be working in cooperation with Hell in order to invade Earth.
 * Betruger reveals that he had already sent the distress call to Earth before Kane reached the backup system, hoping to use the ships bringing reinforcements to transport the demons to Earth.
 * Betruger then unsuccessfully attempts to kill Kane using the toxic gases in the base's recycling facilities.
 * Upon arriving at the Delta Labs, Kane learns of the details behind the teleportation experiments, expeditions into Hell to retrieve specimens and Betruger's increasing obsession with the tests, as well as of a xenoarchaeological dig under the surface of Mars. The dig is excavating the ruins of an ancient civilization discovered on Mars and has produced a relic known as the Soul Cube.
 * According to a scientist Kane finds in the labs, the Soul Cube is a weapon created by the ancient civilization to defend against the forces of Hell. The scientist also reveals that the invasion began when Betruger took the Soul Cube into the portal at the beginning of the graphic novel, depositing it in Hell.
 * Kane pursues Betruger through the labs but is pulled into the main teleportation portal after being lured into a trap by Betruger.
 * The portal takes Kane directly into Hell, where he proceeds to fight his way through a large number of demons to the Soul Cube, defeating its demonic guardian.
 * Kane is then able to reinitialize the teleportation equipment left by previous research expeditions and return to the Delta Labs. Betruger, however, tells Kane that although the main UAC teleporter has been destroyed, Hell is opening a Hellmouth on Mars, capable of bringing millions of demons to Mars.
 * Kane encounters the injured Swann, who informs him that Kelly has been working with Hell for possibly the whole time and has been transformed by the demons.
 * Telling Kane that Campbell has gone after Kelly, Swann gives Kane his PDA containing information on the location on the Hellmouth under the surface of Mars and says that he will try to make his way out of the base alone.
 * However, when Kane catches up with Campbell in the central computer processing sector of the base, Campbell is mortally wounded; before expiring, he says that Kelly has taken Campbell's BFG 9000 weapon.
 * Kelly then begins to taunt Kane in a demonic voice.
 * Kane eventually faces off with Kelly in the central computer core, revealing Kelly as a cybernetic human grafted onto a tank-like base.
 * Kane is able to kill Kelly and takes the BFG 9000 before proceeding deeper under the Martian surface to Site 3, the archaeological dig site where the Soul Cube was unearthed.
 * At the primary excavation site, Kane discovers the Hellmouth, defended by Hell's mightiest warrior, the Cyberdemon.
 * Using the Soul Cube, Kane defeats the Cyberdemon, and the Soul Cube then seals the Hellmouth.
 * The ending page shows the reinforcements from Earth arriving at the base to discover the carnage. They find Kane alive but discover that Swann has died from his injuries. They are unable to locate Betruger, who in the final scene is panel in Hell, reincarnated as a dragon-like demon.

Resurrection of Evil

 * In 2147, two years after the events of Maelstrom, the UAC detects a strange signal from one of its Martian satellites, and consequently sends a team in to investigate. After this, the team finds an Artifact and the forces of Hell are alerted and begin a new invasion.
 * Asher "Sarge" Mahonin, a marine combat engineer who discovers the hellish device, fights way through the base to reach the doctor, chased by demons.
 * Sarge eventually finds Dr. Elizabeth McNeil, the whistleblower who notified counselor Elliot Swann and Jack Campbell of Malcolm Betruger's mysterious activities at the beginning of Maelstrom, and she tasks him with stopping the invasion by returning the Artifact to Hell. In his journeys he defeats the three Hell Hunters (demons who were supposed to find the Artifact) and absorbs their powers into the ancient device.
 * Sarge arrives in Hell and battles his way to Betruger, who has become the dragon-like Maledict.
 * After some fighting, Betruger bites Sarge, but before he can eat him, Sarge shoves the Artifact down Betruger's throat, causing him to dematerialize. Only his skull remains.
 * The graphic novel ends with a bright white light, followed by McNeil's voice saying, "Sarge?... Welcome home."

The Lost Mission

 * John "Reaper" Grimm is the last surviving member of Bravo team, which was seen being ambushed by demons in Maelstrom.
 * Grimm is contacted by Dr. Richard Meyers, a scientist working on teleportation experiments in Exis Labs, and asked to help Meyers destroy an experimental teleportation array that was captured by the demons and is currently held deep inside Hell.
 * The array is potentially powerful enough to send an army of demons all the way to Earth, hence Meyers' desperation to destroy it. To achieve this goal, Grimm must acquire the components necessary to activate the Exis Labs teleportation system, then travel to Hell in order to destroy the teleportation array.
 * In the epilogue, Grimm is teleported by Dr. Meyers back to Mars.
 * The reinforcements from Earth arrive to search for another marine who is still missing; eventually, they find him in the Delta Labs complex.

Unto the Evil

 * Unto the Evil takes place during the year 2149, in a research facility located in the Hellas Planitia on Mars owned by the Union Aerospace Corporation. The facility is run by Dr. Samuel Hayden, a UAC scientist whose mind now inhabits an android body after having lost his original to brain cancer.
 * Researchers at the UAC facility have attempted to draw energy from Hell, a newly discovered alternative dimension inhabited by demons, in order to solve an energy crisis on Earth. They accomplish this using the Argent Tower, a structure which siphons "Argent Energy" from Hell and allows travel to and from the other side.
 * In addition to their energy harvesting work, Hayden organizes several expeditions into Hell, bringing back captive demons and artifacts for study. Among them is a sarcophagus containing the Doom Slayer along with his armor, the Praetor Suit.
 * The facility is overrun by demons after one of Hayden's researchers, Olivia Pierce, makes a pact with them and plots to use the Tower to open a portal to Hell.
 * In desperation, Hayden releases the Doom Slayer from his sarcophagus to repel the demonic invasion and close the portal.
 * The Doom Slayer recovers his Praetor Suit and fights his way through the overrun facility, guided by the self-aware AI VEGA, which controls the facility. After clearing out the facility core and preventing a meltdown, he pursues Pierce and destroys the energy induction filters, despite Hayden's objections. He tracks Pierce up the tower, where she uses an Argent accumulator to open an explosive rift into Hell, destroying the Tower and sending the Slayer back to Hell.
 * Fighting his way to a teleporter, the Doom Slayer returns to Mars and makes his way to a tram leading to Hayden.
 * Hayden informs the Slayer of the Helix Stone, an artifact used to study and harness Hell's Argent Energy. Entering Pierce's Lazarus Labs, he observes the Helix Stone and he learns of the Well, where the portal is powered, and of the Crucible, a magical key-like blade. He makes another excursion into Hell by activating the accumulator of a contained Cyberdemon that he defeats and fights through a labyrinthine gauntlet to recover the Crucible from a trio of Hell Guards. Arriving at VEGA's facility in the frozen north, he makes a backup copy of the AI and destroys the facility.
 * The explosion of VEGA's core allows the Slayer to enter the Well, where he uses the Crucible to destroy the portal's power source. Finally, he confronts Pierce, who is betrayed and transformed by the demons into the monstrous Spider Mastermind. She attempts to kill the Slayer but is eventually defeated.
 * Upon the Doom Slayer's return to Mars, Hayden confiscates the Crucible, which he plans to use in his research. Despite all that has happened, he insists that Earth is too desperate for energy to give up.
 * To keep the Doom Slayer from interfering with his plans, Hayden teleports him to an undisclosed location, saying that they will meet again.

Hell Followed

 * In 2163, fourteen years after the events on Mars, Earth has been overrun by demons, wiping out 60% of the planet's population, under the corrupt Union Aerospace Corporation (UAC).
 * What remains of humanity has either fled Earth or joined the Armored Response Coalition (ARC) resistance movement.
 * The Doom Slayer, having previously been betrayed by Dr. Samuel Hayden, returns with a satellite fortress controlled by the AI VEGA to quell the demonic invasion by killing the Hell Priests: Deags Nilox, Ranak, and Grav. The priests serve an angelic being known as the Khan Maykr who seeks to sacrifice mankind for her own race's survival.
 * The Slayer teleports to Earth and kills Deag Nilox, but the Khan Maykr transports the two remaining priests to unknown locations.
 * The Slayer retrieves a celestial locator from the Sentinel world of Exultia then a power source in Hell from the exiled Sentinel the Betrayer, who also gives him a dagger that he asks Slayer to stab the heart of his son with, whose body was turned into the apocalyptic demon, the Icon of Sin.
 * The Slayer finds and kills Deag Ranak at his citadel in the Arctic. In response, the Khan Maykr moves Deag Grav again and accelerates the invasion of Earth.
 * With no leads on the last Hell Priest, VEGA suggests finding Dr. Hayden, who knows his location.
 * At an ARC compound, the Slayer retrieves Hayden's damaged robot chassis and the demonic Crucible.
 * Upon uploading Hayden's mind into the fortress, he reveals Deag Grav is hiding on Sentinel Prime; the only way to get there is a portal located in the lost city of Hebeth in Mars' core.
 * The Slayer travels to the Martian moon Phobos, where he uses the BFG 10000 to shoot a hole in the surface of Mars to reach Hebeth.
 * After reaching Sentinel Prime, flashbacks reveal the Slayer to be Doomguy.
 * Found badly wounded by Sentinels sometime after Absolution, Doomguy was brought before the Deags and forced to fight in a gladiatorial arena. Impressed by Doomguy's ruthlessness in battle, the Deags inducted him into the Sentinels.
 * In the present, the Slayer finds and kills Deag Grav in the arena.
 * The Khan Maykr reveals to the Slayer her plan to resurrect the Icon of Sin to consume mankind.
 * The Slayer travels to the Sentinel homeworld of Argent D'Nur for his own Crucible.
 * Further flashbacks reveal that during the battle of Argent D'Nur, a rogue Maykr called the Seraphim imbued Doomguy with superhuman abilities by putting him in the Divinity Machine, transforming him into the Doom Slayer.
 * It is revealed that the Khan Maykr had made a pact with Hell to produce Argent energy, which is created through the mass sacrifice of human souls. In return for providing worlds for Hell to invade, the Maykrs receive a share of the Argent energy produced by Hell, which allows their own dimension, Urdak, to survive.
 * The Slayer enters Urdak through Hell's citadel Nekravol, and halts the Icon's awakening ceremony by using the Betrayer's dagger to destroy its heart.
 * Free from Maykr control, the Icon of Sin awakens and teleports to Earth.
 * With the dimensional barrier destroyed, the demons break their alliance with the Maykrs and invade Urdak.
 * The Slayer kills the Khan Maykr before returning to Earth to confront the Icon of Sin, although VEGA is left behind to ensure the portal stays open and in doing so, learns that he is the mind of the Father, the creator of the Maykr race.
 * The Slayer kills the Icon of Sin in battle, putting an end to Hell's invasion of Earth.
