Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

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.

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?

Benedict, while being beaten unconscious and having his bones broken, was suddenly the Holder of a Sphere of Regeneration.

Larek Holsten is different from most people living in the Kingdom of Androthe, where his seven-foot-tall frame is looked at with suspicion and anger from its shorter residents; but as long as it helps him become the best Logger he can be, he doesn’t let it bother him all that much. He and his best friend, an axe with a powerful Fusion that causes it to become sharper and stronger than a normal tool, are feared by the trees in the magical forest north of his home, as he can fell the quickly growing monoliths faster than anyone else in the community.

Surviving the first days of the apocalypse, William is a wreck and hiding in an attic. The daily acid storms, floating elementals, and bizarre mutated animals are the least of his problems. The reality-warping apocalypse has rules and a system much like those in video games. To survive, he must learn how the new uncooperative system works, choose a class without any real knowledge of what it does and create a place safe from the spawning horrors.

Follow an unfortunate soul who has been thrown into a fantasy world with nothing. He is quickly railroaded into joining the Legion and has to develop under harsh conditions while slowly discovering his potential power.

Something always goes sideways, but this is bigger than expected. Maybe it's not an entirely bad thing, though, as mana-infected animals spreading over the world would definitely make everyone more open to the idea of the apocalypse. The question is what was Silas supposed to do about it, though.

Bronwic, a recently retired ice hockey enforcer, is trying unsuccessfully to rebuild himself in the remote Milford Sounds of New Zealand when a Mana Influx hits Earth. Danger is everywhere as oversaturated Mana creates wormholes that bring dangerous creatures to Earth.

Ryan lived his life on Earth trapped in his own body. The doctors couldn't explain what was happening to him, but slowly, his body was crystallizing. Then, a portal opened up on the ceiling of his hospital room. He'd seen that one in enough anime to recognize what was happening. It couldn't possibly be worse than the hell that was his life on Earth, not that he was given any choice.

With his wounds healing, his strength grows tremendously, opening up a new evolution of bonecrafting. To reforge his eldritch body, Besal, Hal's Beast, ventures into the depths of the Fathomway dungeons, chasing after the source of the land's corruption.

Multiverse Z came knocking, snatching all the humans from Earth to integrate with their game-like realms of magic. No warning. No tutorial. It's an instant transition where eighteen-year-old Joey Eclipse is thrust from his relaxing night playing video games to a stone room with two doors. There's nobody but him. The system messages asking some cryptic questions: [Adventurer or Commoner?] [Greatness or Steadiness?] And more. Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

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.

Jason and his friends just wanted to spend a week at the lake house. Time to relax, hang out, and catch up on old times. Then the System arrived. It only took a few hours for their world to become a real-life roleplaying game; trading some downtime for the need to learn new skills and powers while trying to defend their new home, their families, and survive. They don’t know the rules. They don’t know what’s coming next. What they do know is; they need to reinforce and expand their fort while protecting it, keep leveling up, and explore a dangerous new world.
