The eleventh floor: a vehicle-based race where the party that finishes last loses its survival containment.
Quasar reveals the name of the coming floor to Carl after Carl consents to the penalty — learning it adds a full season to any exit deal taken before the floor ends, though Carl had just earned a free season back from a quest. The information released is limited.
On Don't Come in Last, the party leader chooses a matter of conveyance, biological or mechanical, and the party travels from point A to point B; on reaching point B they are offered an upgrade option for the vehicle. Travel is only permitted using the vehicle, a fixed number of journeys must be made, and if a party comes in last place the survival containment around its vehicle is removed. Multiple NPC teams compete, so crawlers are not necessarily racing each other directly — which Quasar notes is fortunate, since this is not a Battle Royale season. Carl immediately thinks of how Katia would have excelled at it.
Known only through a briefing sheet: a course of staged journeys run in chosen vehicles between fixed points.
The eleventh floor of the crawl, structured as an elimination race against NPC teams.
