Hollow Earth Expedition

First we discovered that the Earth is round.

Then we discovered that it’s hollow.

Now we must keep its secrets from falling into the wrong hands.

Explore one of the world’s greatest and most dangerous secrets: the Hollow Earth, a savage land filled with dinosaurs, lost civilizations, and ferocious savages! Players take on the roles of two-fisted adventurers, eager academics and intrepid journalists investigating the mysteries of the Hollow Earth. Meanwhile, on the surface, world powers and secret societies vie for control of what may be the most important discovery in all of human history.

Set in the tense and tumultuous 1930s, the action-filled Hollow Earth Expedition is inspired by the literary works of genre giants Edgar Rice Burroughs, Jules Verne, and Sir Arthur Conan Doyle. The subterranean action is powered by Ubiquity, an innovative roleplaying system that emphasizes storytelling and cinematic action.
