A/N: I got bored of waiting for Doom Eternal to come out on March 20th, so I'm uploading the first several chapters weekly. Just a disclaimer, the first three chapters after the prologue are based around the first three levels of Doom Eternal that ID has shown, but the events will most likely be different than in the game. Also, at around chapter 4, I introduce the subplot about multiverse hopping. Finally, I already have my own ending written out, so matter how Doom Eternal ends, that's not how this story goes.

Now let's get this party started.

"Blessed is the one who reads aloud and blessed are those who listen to this prophetic message and heed what is written in it, for the appointed time is near."

- Revelation 1:3

Hell.

It has gone by many names. The Lake of Fire, or the Underworld. The Greeks came to call it Hades, after their heathen god, or even Tartaurus. The ancient Hebrews had a slew of synonymous names; Sheol, Gehenna, and Abaddon. The poet Dante labeled it as the Inferno. Even the Norse had their own idea of Hel, albeit shortened from the original title.

Hell has taken many forms. A realm where the dead roam. A place where evil spirits reside, and are tortured for eternity. A landscape of molten fire and brimstone. Some would say that Hell is a barren Wasteland, while others would claim it is merely a twisted depiction of how our world is, to the point of unrecognizability. Or rather, Hell is simply a dark, inky abyss, where you can not see what is in front of you.

All these depictions are quite different from one another, but they have one thing in common: they are all accurate.

Hell changes appearance to suit what the soul believes, whether it is a wasteland, a pit, or fire and brimstone raining down on them. Each of these versions of Hell exist in their own separate dimensions, and the soul subconsciously decides for itself which one it gets sent to. But now, that will all change, for one such dimension discovered how to cross over, and they are eager to invade not just Earth, but other hell's realms...

Al Simmons, better known to the world and to Hell as Spawn, opened his eyes to find himself in the underworld, surrounded by Malebolgia's enslaved souls.

You have squandered the gift we have given you. The demon overlord roared. We let you see Wanda, and in return, you will lead my army!

"Sorry I didn't feel like doing your dirty work." Spawn snorted. "I told your little freak I'll be coming for you next."

"Yeah, sorry, he wasn't in the office, so I had to leave him a note."

Spawn turned around, seeing a fat man with white and blue clown makeup on his face waddle towards him. Unfortunately, he knew the clown well by his true name; the Violator.

"Aw, poor Spawny's been a bad boy!" the Violator chuckled. "You're gonna be put in time out for not leading Hell's army!"

"How about you shove your army up your ass!" Spawn shouted, preparing to attack. Before he could, however, Al looked up, seeing the fiery hole above turn a deep shade of crimson and demons that he had never seen before began spilling through. Some appeared bipedal, but had spikes jutting out their shoulders, others were giant red orbs with green eyes. There were even tall skeletons with- were those jetpacks they had?

The new demons quickly swarmed around Malebolgia and his minions, beginning to tear them apart.

What is this? Malebolgia's voice boomed with raw hatred. Who dares?!

Spawn, wisely making the decision to avoid engagement for the time being, concentrated on reaching the portal out of Hell. In an instant, his necroplasm suit expelled a green supernatural energy, and he shot into the air. One of the skeletons with the jetpack device attempted to chase him, but was quickly halted by a green fireball that Spawn threw.

Simmons reached the portal and felt himself ascending, before falling into an alley in front of an old man in a trenchcoat and wide brimmed hat

"I see you escaped Hell yet again." the old man noted.

"Yes, but I was attacked."

"You've been attacked before." the man reminded him.

"Not like this, Cogliostro." Spawn told him. "Demons invaded Hell. They weren't like anything I've faced before."

"That's impossible." Cogliostro exclaimed. "How can demons invade Hell? They should already be there!"

"I don't know." Spawn admitted, thinking back to the demon's odd appearance. "But I don't think this is over…"

"Astra, look, I came down here for a friendly chat." John Constantine told his old friend, as well as his greatest failure, Astra Logue. "We don't have to be enemies."

"You're not my enemy John." Astra chuckled. "You're an important step in my evolution." John was about to retort, when he heard screaming from outside. Usually, he wouldn't care, as this was Hell, but something seemed off. Astra apparently sensed the same thing, and they both rushed to the window.

Outside, the sky had turned a blood red, and thousands of demons that neither of them have seen before were tearing apart the denizens of Hell. These creatures were more vicious, more brutal, than anyone John came across. Not even Lucifer Morningstar's own personal demon, Mazikeen, was this blood thirsty.

"What's going on?" Astra demanded, accusing John. "Is this your doing?"

John was about to respond, when he looked at his hand, which was being consumed by a blue fire.

"Oh bugger…" John muttered, before being completely engulfed in the flames.

Constantine appeared back on the Waverider, looking into the faces of Sara Lance and Ava Sharp.

"So how did it go?" Ava asked.

"Bloody Hell, I really need that drink." Constantine mumbled, as he walked away.

Robbie Reyes walked through the darkened plains of Hell, uncertain of what the Spirit of Vengeance wanted him to do this time. With time moving differently than on Earth, it had felt like weeks- heck, years- since he helped SHIELD destroy a rogue machine named Aida and went back to Hell for good.

The Ghost Rider's thoughts were interrupted, when a man in a black coat appeared to him out of pure darkness, tapping a black cane with a skull head on the ground.

"Hello, Mister Reyes."

"Mephistopheles." Robbie growled, and his eyes began burning orange. "What do you want?"

"Just a friendly talk." Mephisto chided, smirking. His smile dropped, and pointed to the sky. "Have you noticed the weather?"

Robbie looked up, seeing the skies turn a blood red.

"That's new." Reyes blinked in surprise.

"Indeed." the Devil agreed. "It has been foretold, that one of the dimensions of Hell would rise up and invade all the others."

"What do you mean?" Robbie demanded, turning back to face Mephisto. "Who's coming?"

"You will come to discover that yourself." Mephisto tapped his cane, and an interdimensional portal opened. "However, I believe you will be needed on Earth for the time being."

With a wave of his hand, Reyes felt himself pushed by an unseen force, and fell through the portal, finding himself back in Los Angeles.

Ash Williams drove his modified Delta through the apocalyptic wasteland of Michigan, having the time of his life as he ran down deadites with the scoop on the front.

"Man, I wish Kelly and Pablo were here to see this!" Ash left, sticking half his body out to shoot a passing deadite with his boomstick. Meanwhile, the robotics enhanced companion, Lexx, fired round after round from the turret mounted on top of the car.

"Sire, look!" Lexx shouted, pointing across the horizon. Ash looked up, confused, as he saw the skies turn a blood red, and demons appearing out of crimson energy. "More deadites!"

"I don't think these are deadites…" Ash exclaimed, stopping the Delta and seeing a skeleton with a jetpack and miniature rocket launchers descend down and kill several deadites in its way.

"Sire, what do we do?"

Ash was wondering the same thing, when the demon turned around and faced the Delta, roaring loudly.

"Deadite or not, it's roadkill now!" Ash grinned, pressing the pedal to the floorboard and zooming straight towards the new demon.

Across the dimensions, many individuals saw similar occurrences. A man with red skin and a stone hand watched, as the skies opened up and demons spilled into the streets of London.

Inside the labyrinth, home of the cenobites, the Hell priest known as Pinhead looks on as a massive monster with horns topples their god, the Leviathan.

Amidst sitting on his throne, high above the many cells in the ash ridden kingdom, Lucifer Morningstar stands in shock, seeing his realm breached by demons that he has heard of, but never expected to come into contact with. The last time he saw the skies turn red, there was a crisis. This was far different, and arguably much, much worse.

It was the end of all life as they knew it.

A/N: Oh, forgot to mention that for every chapter, I'm going to add a bible verse from the Book of Revelation. By the end of the story, it'll make sense.
