The aliens didn't conquer Earth. They negotiated exclusive streaming rights instead. Unbeknownst to humanity, the powerful Voltaxians controlled the galaxy, their vast empire fueled by their monopoly on mana. Humanity feared invasion, only to find out the godlike aliens had something far different in mind. The Voltaxians offered a simple deal. Allow them to set up dungeons controlled by living intelligent dungeon cores on Earth to generate mana, and they'd share the wealth.

Maxwell Carter works a maintenance job at a government research facility. The research lab he works at has an accident, more energy coming through the wormhole than anticipated, enough to completely rupture the shields that were supposed to contain it until they finished determining how to convert the energy into electricity. Previously harmless animals are changed to nightmare threats and people are dying, seemingly due to incidents related directly to their interests.

Born to a Magical Fantasy Princess and a nine-to-five Supervillain in the most superhero riddled city in the world, Perry's never felt...adequate. He's got no talent for magic, and not a scrap of superpowers to his name. When The System boots and unlocks his powers, it forces him to follow in his father's footsteps, but he'd rather take after his mother... Maybe there's a way he can do both...

Jack Atlas, self-proclaimed 'World's Best Assassin', had a simple plan: retire in style and marry the girl of his dreams. Then he gets placed in The Tower—a divine deathtrap where gods pit their creations against each other for the ultimate prize: eternal paradise for you and your friends. The catch? If you lose, well, let's just say your chances of finding a decent bar in oblivion are slim.

Aided by his talking goose animal companion, magical cape, and the Goddess of Fate herself, Dirk is primed to take this Tower by storm.

A visit to London’s Natural History Museum became a horror show as magic flooded Earth. Now, Thomas is entombed there as a Dungeon Core, with only the creatures on display available as minions.

Adam isn't isn't even given the chance to lick his wounds after a deep betrayal before a mysterious force pulls him into into a new, fantastical world. He doesn't mind much. Penniless, luckless, and aimless, Adam wasn't particularly fond of his old world anyway. Maybe this can be the fresh start he needs. First, he'll have to deal with being attacked by shadowy monsters, imprisoned by guardsmen, and pressed into service by the resident nobility. But unlike Earth...he's not entirely powerless.

The System is here! Most of the population of the planet were suddenly turned into zombies, while the rest acquired new abilities. Abilities that let them run from the zombies, save themselves, hide, and try to survive. But it only takes one bite that almost always means death. Our hero was standing in line when the apocalypse came. He was lucky at first to be caught in a crowd when the zombies tried to bite him on the leg. Really lucky, because those trials unlocked new abilities for him.

A Secret Service operative and dedicated survivalist, Special Agent Del Roosevelt had a plan for every world-ending scenario and regularly trained for them all. He was even ready for a date with the hottest woman in his office next Friday. At least he hoped so. But all that training, all those rations, all that prepping? Useless for the apocalypse that actually played out. Del wakes up half-buried in a giant trash pile, missing his thumbs. And, um, covered in red fur. He's stuck in a world of fuzzy monsters, senseless violence, and cult-like crusaders.

It was supposed to be another boring day at the insurance office for Rico Kline, but powerful forces had other plans for him. Finding himself repeatedly summoned to other worlds as a disposable minion, Rico must face deadly foes, disarm insidious traps, become a test subject, and run the occasional errand for his various summoners.

Zane was driving home from work when the world changed. Thousands of dungeons spawned at once, taking up every inch of Earth—including the road he’s driving on. He wakes up to a totaled car and a broken leg, facing down a goblin trying to spear him through the guts. And that's just the start of it. But to Zane’s surprise, he finds himself enjoying this brutal new world. While others cower and hide, he goes on the hunt. He unlocks a unique Berserker skill—the more damage he takes, the stronger he gets.

As humanity is taking its final breath, facing extinction from a myriad of monsters, the last three people on earth are creating a final chance for the hero to go back in time and stop the apocalypse. However, before the hero can enter the chronomancer portal to the past, she and the portal's creator are both killed, leaving only the weak assistant to carry on their dream of saving the world. Will Nick be able to right the wrongs done to him, and prepare the hero for the world to come?

Max was murdered, but now he is mostly over it. Living on earth as a recent college graduate, he can still perfectly recall his past life on the fantasy world of Albion before that. He'd been hailed as the "Hero of the World" after crawling his way up from poverty, eventually enjoying great fame and luxury. But on mana-starved Earth, he's just a guy.

Benny White had been having a rough couple of years, and the approaching apocalypse wasn’t exactly helping. Pulled from the point of death and thrust into a horde-mode-style survival game, Benny’s odds weren’t looking too great. To make matters worse, an eldritch god… entity… thing named ‘Dave’ tasked him with destroying the very System that now controls his fate. But hey, it's not all bad news. Benny’s experience as a lab tech grants him a rare Splicer Class that lets him repurpose the genetic material of slain enemies into augments for himself.

Ragnarok is near and the Vikings of Midgard have failed to uphold their duty to prevent it. With time running out, the All-Father Odin himself, searches all the worlds for one last warrior who might hold back the destruction threatening Nine Realms and every world created. Magnus’s death caught the All-Father’s one good eye. As an Army Ranger, he knew he was placing himself in the line of fire every day, and knew a day could come that cost him his life. What he didn't want was the rest of his team would be wiped out with him, the worst disaster the Rangers had experienced in decades.
