The tenth floor's core mechanic: a lethal race where the last-place team is instantly killed.
A Heat is one of the seven races that make up the tenth floor, 'Don't Come in Last.' Each heat pits nine teams against one another on an AI-designed track; the team that comes in last is killed on the spot, along with their garage attendant. A different party member must drive each heat (so a two-person team like Carl and Princess Donut must alternate). Movement spells like Teleport are barred on vehicles, and vehicles may attack but not steal one another.
Winning a heat grants three upgrades or one Golden upgrade; coming second-to-last surrenders your upgrade to an audience vote. The first three heats run on paved tracks, with hazards escalating thereafter.
A high-speed race across shifting AI-built tracks, hazards and terrain changing every round.
The recurring life-or-death race that structures the entire tenth floor.
