Welcome to the Gun Show! The top ten list is populated. The sponsorship program is open. The difficulty is ramping up. The first three floors were nothing compared to what Carl and Donut now face. The Iron Tangle. An impossibly-complicated subway system built out of the world's subterranean railway systems, all combined and then tied together into a knot. Up is down. Down is up. Close is far. The cars are filled with monsters, the railway stations are less than safe, and the exit is always just a few stops away. But there is hope. For the first time, the crawlers are all working together. The loot is better than ever. And the secret to unraveling it all may be hidden in the pages of a seemingly-useless book. Welcome, crawlers. Welcome to the fourth floor of the dungeon.

"The training levels have concluded. Now the games may truly begin." The ratings and views are off the chart. The fans just can't get enough. The dungeon gets more dangerous each day. But in a grinder designed to chew up and spit out crawlers by the millions, Carl and Princess Donut need to work harder than ever just to survive. They call it the Over City. A sprawling, once-thriving metropolis devastated by a mysterious calamity. But these streets are far from abandoned. An undead circus trawls the ruins. Murdered prostitutes rain from the sky. An ancient spell is finally ready to reveal its dark purpose. Carl still has no pants. They call it Dungeon Crawler World. For Carl and Donut, it's anything but a game.

The apocalypse will be televised! A man. His ex-girlfriend's cat. A sadistic game show unlike anything in the universe: a dungeon crawl where survival depends on killing your prey in the most entertaining way possible. In a flash, every human-erected construction on Earth—from Buckingham Palace to the tiniest of sheds—collapses in a heap, sinking into the ground. The buildings and all the people inside have all been atomized and transformed into the dungeon: an 18-level labyrinth filled with traps, monsters, and loot. A dungeon so enormous, it circles the entire globe. Only a few dare venture inside. But once you're in, you can't get out. And what's worse, each level has a time limit. You have but days to find a staircase to the next level down, or it's game over. In this game, it's not about your strength or your dexterity. It's about your followers, your views. Your clout. It's about building an audience and killing those goblins with style. You can't just survive here. You gotta survive big. You gotta fight with vigor, with excitement. You gotta make them stand up and cheer. And if you do have that "it" factor, you may just find yourself with a following. That's the only way to truly survive in this game—with the help of the loot boxes dropped upon you by the generous benefactors watching from across the galaxy. They call it Dungeon Crawler World. But for Carl, it's anything but a game.
