-1931- during an expedition to Antarctica, scientists have exposed the vestiges of an ancient city of gigantic proportions behind a chain of, to all appearances, impassable mountains. You must work together and communicate well to successfully scale this mountain, find fascinating relics, then escape from this accursed place. Above all, be careful not to lose your health or your sanity! The goal of your expedition is to recover the relics hidden on the mountain. What you do not yet know is that it also hides terrible secrets that are better left untouched. As members of this strange expedition, you will face challenges whose horror you cannot fully comprehend.
By using the equipment on your cards, you must work together to overcome these horrifying challenges. Do your best, since times matters! Each challenge overcome makes the road to victory easier, but if, despite your best efforts, you do not succeed, you will suffer injuries or even lose your sanity. The closer you get to the Summit, the greater your madness will become. And as madness seizes each member of your team, it becomes that much harder to communicate with each other, as you head towards your inevitable demise. If, by chance, you manage to escape, you will need to assess your team. At the end of the game if you have more relic cards than injuries, your expedition was a success and you win the game. If the opposite is true, the expedition turned out to be much too costly for the few discoveries made and you lose the game. But that is nothing compared to losing all hope of surviving in this hostile terrain.
