Chained Heat 3: Hell Mountain [hot] -

Zero. Unofficially: Two teams in three years have reached the summit unit. One team (Team Ghost, 2021) refused the final cool-down chamber due to hypothermia risk. The other (Team Ash & Ember, 2022) completed the chamber but their chain had to be cut off afterward — both suffered second-degree burns to the wrist. Their finishing time: 11 hours, 47 minutes.
