Mountains of Madness
Inspired by the haunting novella `At the Mountains of Madness` by H.P. Lovecraft, players in Mountains of Madness are passengers in a plane who have to cooperate to reach the top of the Mountain, then escape safely - but, the Mountain has more than one trick up its ghastly sleeve!
In horror, you realize that the higher you fly, the crazier your teammates become! Each step you take, the team leader must gather the necessary equipment from all other players to keep the plane aloft.
Clear and concise communication is the key - but, how will you stick together when your team starts developing weirder and weirder behavior?
