Registered alien participants who pay to hunt crawlers for gear, starting this season at level 50.
The sixth floor opens with 360 Hunters on deck, all transferred to the city of Zockau and sequestered for a 30-hour Grace Period before release. Registration is being kept open to the last moment, and the showrunners expect the count to double or triple. Normally hunters enter at level 30 and train themselves up while crawlers work down the earlier floors; because this season's crawlers arrived early, all hunters received a 20-level bump and begin at level 50. Some have been in place for weeks, and their minions and traps are already loose in the jungle even while they are penned.
Ian, a bush elf attendant and former crawler, calls them aliens who do not fight fair and warns Carl to stay away from Zockau even after the countdown ends. He says a core group of roughly twenty regulars returns every season, chief among them the mantis Vrah, whose death count runs into the thousands.
