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.

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.

Benedict Aaron Rodney had a terrible life for eighteen years. Then, something miraculous happened: the Heavens stepped in, granting him a Sphere. Spontaneous manifestation of a Sphere was very rare, but it happened on occasion. Benedict, while being beaten unconscious and having his bones broken, was suddenly the Holder of a Sphere of Regeneration.

Hiral is the Everfail, the weakest person on the flying island of Fallen Reach. He trains harder than any warrior. Studies longer than any scholar. But all his people are born with magic powered by the sun, flowing through tattoos on their bodies. Despite having enormous energy within, Hiral is the only one who can’t channel it; his hard work is worth nothing. Until it isn’t. In a moment of danger, Hiral unlocks an achievement with a special instruction: Access a Dungeon to receive a Class-Specific Reward.
