The 30-hour head start crawlers get on the sixth floor before the hunters are released from Zockau.
The sixth floor opens with the announcement that the Grace Period begins immediately, that all hunters have been transferred to the city of Zockau, and that they will be released in 30 hours. The message ends with a single word: Run. The countdown is separately tracked as Time Until the Hunt Begins.
The protection is partial at best. Registration for The Hunt stays open until the last moment, so the roster of Hunters can double or triple before release, and while the hunters themselves are sequestered, their minions and traps are already scattered across the jungle — a few crawlers have already discovered this the hard way.
