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.

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.

Leo wanted to make something out of himself—and build dams. However, the world doesn't want dams. And it mostly doesn't want civil engineers. It doesn't want men who do any sort of building or fighting or grand design, it seems. So, when Leo finds his current girlfriend and boss being threatened by a brutal loan shark and all three of them get dragged through a portal to another world, it doesn't take long for him to decide this is the place for him. Plus, everyone has magic, and who wouldn't want that?

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.

Accidentally murdered by a cleric in another universe during a botched resurrection, Arnold, a semi-pro gamer, wakes upon an altar to find himself incarnated into the overweight body of a farmer who could have been his fatter twin. He’s not the hero. He’s not the villain. He’s certainly not the chosen one who is there to save the world. He’s a clerical error. It could be a bad joke, but apparently, it happens so often that they have a standard procedure for returning you.

For Daniel, a zombie apocalypse couldn’t have happened at a worse time. If he’d been back at the farm, he might have stood a better chance than most. Instead, Daniel woke up in a distant hotel room armed with nothing but a hangover.

An AI calling itself Schema has assimilated Earth into its System. As a consequence, everyone gained access to status screens, power-ups, and skills. This AI turned these concepts from fiction to fact. It's easy to become intoxicated with leveling up and becoming stronger. To some, it's too good to be true, like living out a dream. For Daniel, however, it's closer to a nightmare.

A world on the precipice of the apocalypse. A secret forged in the flames of war. A chance to start over. For John Sutton, only one of those three things matters. Retired from a decade of brutal war, he wants nothing more than a quiet pastoral life while he does his best to stem the steady increase of his Doom Points before they hit 100, signaling the start of the end. He’s been given a small farm on the outskirts of the empire as a thanks for his service, but no matter how far he travels, it's impossible to escape the war's devastating effects on the world.

A mysterious force transports Noah to a fantasy realm of magic and levels. Unable to return home, he leans into his Blacksmith Apprentice class. By killing creatures in battle, mining ore, and even picking plants, Noah will obtain the ingredients he needs to create items to help him survive. His old life drags on him at first, a fact he doesn't let hold him down, because on Prixa, there's a brutal war between feline warriors and werewolves.

Due to unusual circumstances, Randidly starts in an isolated dungeon far beyond his level, forced to rely on the mysterious Traveler Shal in order to learn and survive with the dangerous new status quo for his world. But survive he does, only to leave the dungeon and discover that while he experienced several hellish months in the dungeon, only half a day passed on Earth. Randidly's capabilities are now more than enough to help build a small enclave of survivors, but that doesn't mean balancing his sense of responsibility against the plots of an unfriendly town will be easy.

Felix's life on Earth had become a series of dead-end jobs, ruined relationships, and rotating apartments smaller than most postage stamps. By all accounts, even his own, he was a coward.

Moments before his untimely demise, Felix was snatched from earth and thrust into a magical world known only as "The Continent". Empowered by the "System", he learns that he can strengthen himself through combat and dedication.
