New Achievement! Total, Utter Failure. You failed a quest less than five minutes after you received it. Now that’s talent. A floating fortress occupied by warrior gnomes. A castle made of sand. A derelict submarine guarded by malfunctioning machines. A haunted crypt surrounded by lethal traps. It was supposed to be easy. One bubble. Four castles. Fifteen days. Capture each one, and the stairwell is unlocked. Here's the thing. It's never easy. Carl and his team can't go it alone. Not this time. They must rely on the help of the low-level, I-can't-believe-these-idiots-are-still-alive crawlers trapped in the bubble with them. But can they be trusted? Welcome, Crawler. Welcome to the fifth floor of the dungeon.

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.
