Leading astrophysicist Liam Jackson is participating in a scientist exchange program in Germany when a curveball of universal proportions is thrown at him. Planes fall from the sky, cars explode, and strange particles rain down from the heavens as monsters appear out of thin air. The laws of physics have changed in the world. The fundamental forces of the universe are behaving differently, and Liam needs to understand them if he wants to survive.

Jack Rust was a disillusioned biologist with a PhD—almost. When an extraterrestrial AI calling itself the System invaded Earth and thrusts it into a world of aliens and violence, the least Jack hoped for was gaining access to magic.

Nathaniel's bus ride was supposed to be just another boring commute. Wrong. Now, he, 23 fellow passengers, and a corgi named Biscuit, are stuck in a "Hell Difficulty" Tutorial, battling monsters and leveling up to survive. Easy difficulty, anyone can handle. Normal difficulty, you've got to put up a fight to get by. Hard difficulty is where only the tough ones last. And Hell? That's where you have to be a bit out of your mind! With his terrifying talent for mana manipulation, Nathaniel decides to invest every stat point into mana.

Betrayed and left for dead by a group of slaving nobles, he thought there was nothing left but to bleed out as he counted the number of bricks on the ceiling. But fate had other plans.

It was a day like any other when suddenly the world changed. The universe reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A place where power is the only thing anyone can truly rely on.

After his parents died, Alex Roth had one desire: become a wizard. Through hard work, he was accepted into the University of Generasi, the world’s greatest academy of wizardry.... Fate, however, had another plan. On his 18th birthday, he is Marked by prophecy as one of his kingdom’s five Heroes, chosen to fight the Ravener, his land’s great enemy. But his brand is "The Fool". Worst of the marks.

Zac was alone in the middle of the forest when the world changed... The whole planet was introduced to the multiverse by an unfeeling System... or God. A universe where an endless number of races and civilizations fought for power and dominion. Zac finds himself stuck in the wilderness surrounded by deadly beasts, demons, and worse. Alone, lost and without answers, he must find the means to survive and get stronger in this new cut-throat reality.

April 3rd, 3:46 AM. Planet Earth merges with the magical world of Arcadia, and a system gives humanity a choice: 40 years of indentured servitude, or entering a tutorial as a user to fight against the chaos incursion. Will doesn't hesitate—but the system thanks him for stepping into the fight by throwing him into an impossible tutorial. With little chance of survival, Will has a simple response: “Screw it. Might as well fight fire with fire."

She wanted to be a Necromancer, but awakened as a Saint! Somehow her summoned heroes are all undead? How will the church react when their Saintess summons a skeleton in place of a mighty hero? Sofia isn’t too keen on finding out. In this world, Gods choose [Saints], and [Saints] summon [Heroes] from other worlds; everyone knows that. But Sofia had a thing for bones ever since she was a child; there’s only one [Class] she wants: [Necromancer]! When, by the whims of fate, she gets both classes at the same time, the system breaks.

Humanity has fallen, killed by stronger races of beings after being warped away to a new reality, the mystical Seven Layers. Humanity's goal had been simple. Make it through all Seven Layers and reach Heaven. Humanity failed. Humanity died. Micheal Care's memories have been transported back into his past self thanks to a magical Artifact he found by chance. He is no chosen savior. He is no divinely picked hero. Can he change the future?

In just seven days, the world will crumble. The System's Descent will usher in a new era of chaos: wild animals mutating, monstrous creatures emerging, and the cessation of modern technology. Humanity will be left defenseless. Drew Wright knows none of this. At least not until he is rudely ripped from his bed and thrust into a white room to undergo a taser-happy ‘Tutorial’. Turns out, he is one of a thousand randomly selected people to be forewarned of the approaching apocalypse. Now, he faces the delightful task of convincing his wife and mother of the devastation hurtling towards them.

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

With monsters, magic, swords, and Gods, the world of Nava is anything but normal. How will the once-average young man survive as his newfound title of Lost Lord makes him a target for assassins and terrorist organizations? Max’s new home is governed by the strong and over-encompassing System that regulates the world. Whether someone is a [Farmer], [Warrior], or a [Grand Magus], classes and abilities allow some to prosper while others fail.

When the cultivators came to Earth, they destroyed our entire civilization in a matter of hours. Armies fell, cities burned, and that was before the moon turned red and filled our world with monsters. Now, over a decade later, what's left of humanity slaves under the heels of our Qi-infused masters. The luckiest of us might even become one of them, they say—if we serve the Dynasty well enough and harness the power of Qi. But I want none of that. I'm sick of serving, and I want nothing to do with their world. Instead, I want them to pay for what they did to mine.

Jake is working at the neighborhood market under his apartment when the world ends. He expected nuclear war, a computer virus, or even climate change burning everyone to a crisp to bring about the downfall of civilization. But cruel and arbitrary gods from another world? Who would have guessed that? When these cruel gods shuffled Earth like a deck of cards, nothing was in the same place anymore. Monsters, dungeons, and magical items appear scattered across the globe. And suddenly, everyone has access to a new, strange magical card system that gives them magical powers.
