Basil Bohen was asleep when the System arrived and the world changed... Dungeons suddenly popped up across the planet, summoning invaders and monsters from alternate realities. Ancient gods slumbering beneath the Earth were woken. And all humans were empowered with Levels and Classes gained by, amongst other things, killing monsters and other humans.

The decision to start a new life is never an easy one, but for Joe the transition was far from figurative. Becoming a permanent addition to a game world, it doesn't take long to learn that people with his abilities are actively hunted. In fact, if the wrong people gained knowledge of what he was capable of, assassins would appear in droves.

After being killed by a high-velocity tree-hug, Arlo is transported to a new world where those brave and talented enough to conquer ancient Delves are rewarded with incredible power and abilities. Unfortunately for Arlo, there is no tutorial. He is immediately forced to tackle a Delve set to the highest difficulty with a party of adventurers who are not only strangers to him, but strangers to each other as well.

Silas is inducted into the System, becoming the last in a long line of Earth's "forerunners." The rewards are great, but the danger is greater. We are not alone in the universe. The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?

As a monster, Shrubley is forbidden from joining the adventurers guild. In a world where essence artists rank up in power and most monsters are feral beasts, Shrubley is among the weakest of creatures and is treated as an outcast. With curiosity essence bound to his spirit, Shrubley might be weak, but he's intelligent and determined. Against all the odds, he discovers a loophole from the Druid that gave him life—but there's a deadly catch. For a chance of ever being accepted as a true adventurer, he must challenge an otherworldly realm threatening to consume everything.

Orodan was an orphaned street rat who clawed his way to the county militia with hard work. When calamitous events unfold and draw him into events bigger than himself, Orodan's battle-loving disposition leads to a warrior's death. Then he wakes up again at the start of the Cataclysm. Then again. And again. In a world of skills, titles, and blessings, a smart time-looper would perhaps scheme, plan, amass equipment, and allies. But not Orodan. If there's one thing he's good at, it's stubbornly trying the same thing over and over again via brute force till it's done.

When it comes to action and adventure, every hero needs a good sidekick. Holmes has Watson, Batman has Robin, and Daniel has . . . Orrin. More like brothers than friends, they always have each other's backs. And as Daniel is the big, strong, handsome type, Orrin is more than happy to remain in his shadow at school, at parties, pretty much everywhere. Then things take a turn for the truly weird when a terrible accident catapults the pair into a world totally unlike their own, in which the rules of a role-playing game hold sway.

Freddy Stern, a twenty-one-year-old cashier, has lived a plain, albeit harsh life. Having been orphaned—twice—he's spent the last ten years working and staying out of trouble. His only aspiration is to save enough money to become an archhuman. His dream gets the jump on him when he barely survives a near-death encounter and finds himself in possession of 1% Lifesteal, a bizarre talent with numerous contradictions and just as many uses.

By day, Kyrus Hinterdale lives the mundane life of a scribe. By night, he lives out the adventures of Brannis Solaran, a failed sorcerer turned knight. When Brannis leads his battalion into the forest on a routine scouting mission, they are overwhelmed by a goblin force. While leading the survivors to regroup and prepare the empire for the inevitable war, Brannis struggles to understand why a scribe from his own dreams, suddenly seems to be able to perform the magic he never could.

The System warned them. The world panicked. Alex prepared. In college for a degree he didn’t care about, the promise of the System creating a world where magic and challenge awaited—even at the risk of death—was the best news Alex possibly could have imagined. Yeah, Alex was ready for a new life. He wasn’t, however, ready for his only friend to shove him through a portal into hell the moment the apocalypse started.

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.

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."

Mark’s new life begins in the worst possible place—a burned-out village haunted by undead. Each morning these ravenous creatures disappear, only to return at night, driven by a relentless hunger. He'll need to stay low and think quick, because trapped and alone in the body of a child, he can’t level up in this new world. At least not yet. Soon Mark will learn that even among the living, safety isn’t guaranteed. When the small town that he ends up in turns out to be at the center of a conspiracy that threatens the world, he'll need to uncover the truth before it's too late.

Becoming a knockoff Dracula in tight leather pants was never part of Vincent’s plans. Neither was being summoned to another world by a cult of vampire wannabes. But both happened. Now, Vincent’s left to pick up the tattered pieces of his humanity as he tries to grow strong enough to keep his family safe. The world is filled with nightmares, and the looming threat of losing his soul stands between his goal and his reality, so it’s not like it will be too hard or anything. Hell should tremble. A good man is going to war.

On a typical day, on an average train platform, two warring sister goddesses found their avatars. One avatar, the young Yoshi, was swept away to the world of Ephemera to be a great hero of honor, courage, and light. The other, the not-so-young Seiji, was swept away to become a dark lord out to kill or conquer all in his path. But Seiji is in absolutely no mood for that nonsense. It's bad enough that on Earth he was a closed-off, misanthropic grouch with zero patience for other people. Now he's supposed to muster enough of a give-a-damn to lead vile hordes?
