Buried in this mountain are powerful artifacts and treasures, that grant their finders great power. ​In the first portion of the game, players build long winding Lairs towards the center of the mountain. All competing to to claim one of these prizes. Once one player has taken the prize they become the Enemy of the other players. The remaining players become the Allies and must fight their way through each chamber of the Enemy’s lair, and duke it out in a climatic finale.
