Antarctica, in the 1930s. An expedition team discovers a chain of mountains that until then was unknown. Faced with their thirst for adventure, they can not help but explore them and climb ever higher to reach the summit of the highest mountain.
But what they do not know is that this quest runs the risk of ruining them. For many secrets are hidden in this hostile nature, and madness will take hold of them little by little. They believed that they lived a historic moment, but it was in a nightmare that our explorers were engulfed.
You integrate this expedition team and, together, you seek to reach the summit of this chain of mountains and then you escape. In order to win, you must have collected at least as many relics as you have during your ascent.
With madness cards in play, you will have to try to escape from this Hallucinating Mountain. Between the whispering of one, the prohibition of using one's thumbs on another or the strange acts of some, will you come to understand your teammates when resolving the goals of each tile Encounter?
Gradually climb these mountains, face your follies, try to accumulate the maximum number of relics to cancel your injuries during the final count and especially try to escape!
