Mountains of Madness

From BoardGameGeek:

1931: Your scientific expedition discovers a new and intriguing mountain range in the middle of the Antarctic polar circle. Under these challenging conditions, the survival of your team will depend on your ability to communicate with each other and to coordinate your efforts to overcome each obstacle - but what you discover on the way to the highest peak will strongly test your mental health. Will you even be able to understand yourself despite the madness that gradually insinuates itself into your mind? Based on the novel by H. P. Lovecraft, Mountains of Madness is a fully cooperative game with a pinch of real-time gameplay.
