Marc's home from college on break, spending his time laughing about some of the crazy news stories he's found online, and gaming.

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.

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.

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.

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?

The only thing standing between Garrett and a cold death at the mercy of the city’s scavengers are his own wits and a plucky young woman.

Now, as Montana, the larger-than-life tank warrior, he has one more last time to get his life right.

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.
