Discover the farthest reaches of Antarctica in Mountains of Madness, the second expansion for Eldritch Horror. Inspired by H.P. Lovecraft's novella, this expansion lets you trace the path of a doomed expedition and enter the immense City of the Elder Things. What happens in Antarctica has worldwide consequences as freshly-awakened horrors spread across the globe.

Eight investigators bring new roles to play as you confront these chilling, inhuman threats. Numerous additional Assets, Spells, Artifacts and Conditions may aid investigators or harm them, and for the first time, Adventures and Prelude cards shape the international struggle against the Ancient Ones. Do you have the strength to make it through Antarctica’s frozen wastes, encounter the Mountains of Madness, and stave off the end of human civilization?
