Floor 10: Iron Tangle Grand Prix
Overview
Floor 10 is the Iron Tangle Grand Prix — a seven-heat vehicle racing competition across multiple tracks within the Iron Tangle industrial network. The floor replaces the traditional safe room timer with a Blood Bar: crawlers must kill enemies to refill it, or they die at the starting blocks.
Approximately 989 crawlers entered Floor 10. By the end, 23 survived to reach Floor 11.

Key Sub-Locations
Satan's Water Park
A water park overseen by Satan — a kaiju-sized hedgehog country boss with a British accent. Used as the arena for Heat 4. Carl's team deployed zipper shrews and a Big-Ass Magnet as race strategies here.
Gasworks Screw Factory
An industrial facility with conveyor belts, inverted ceiling sections, and a screw vat. Used for Heat 5. Below the factory floor: a "toddler cocaine room" — a knocker (elemental) drug operation. Lady Dominators fell through a trap door into this area.
Notable Heat 5 events: Corcunda reunion via Grigori's fleshmancy on the inverted ceiling; Grull appeared; Dong and Corcunda died charging Grull with the Big-Ass Magnet lance.
L'Engle Building
An apartment building where crawlers were miniaturized to lego-size and raced through apartments containing "what-if" simulations of each crawler's real life. The dungeon AI's mandatory quest "Ad Infinitum" required collecting seven rings hidden in the simulations. Apartment scenarios showed alternative life paths (e.g., Tran's family; Imani's family; Prepotente's mother as a New York pianist).
Notable Heat 6 events: Sacred Feaster Scarab Beetles (from Khepri) appeared as unplanned threats; Carl killed Jasha and Radoslav (Team Free Love) with a planted beer can bomb to avoid last place.
The Desperado Club
An NPC nightclub and casino. Connected to the Pineapple Cabaret via a roulette wheel Nothing portal. By late Floor 10, the club was infested with Shadow Mimics. Carl's group robbed the casino to access the Nothing portal — revealing Mitch Fiorelli (Level 120 Shadow Mimic) as the croupier.
Hungry Eyes Restaurant
A nearby restaurant area that became a gathering point for Carl's group during Floor 10 downtime.
Lollipop Bar
A bar where Carl sang "Take on Me" by A-ha during a brawl, earning permanent Stage Performance Guild access. Dwight got drunk here during safe room time.
Sam Town
Samantha's designated safe room domain. Features pink light and looping early 2000s rock music.
Pineapple Cabaret
A pocket dimension escape route built by former crawlers Herot and Menerva, accessible via the Desperado Club's Nothing portal. See Pineapple Cabaret for details.
