A dying world plagued by ceaseless conflict smolders in the night sky, home to the revelations of Mars.
This sourcebook expands Hollow Earth Expedition to include Mars, a dying and dangerous planet filled with strange aliens, bizarre creatures, and vast, inhospitable wastelands. Fight for survival or vie for supremacy as a marauding sky pirate, powerful robot bodyguard, or conniving Martian noble. Experience Hollow Earth Expedition from an outside perspective—one that wields powerful weapons and hungers for earthly treasures as much as any terrestrial power.
Inside you will find everything you need to run out-of-this-world adventures or give your existing Hollow Earth games a bizarre twist: guidelines for creating robot and alien player characters; new and expanded psychic powers; an unearthly bestiary and equipment list; and details on strange Martian inhabitants and extraterrestrial locations. Hollow Earth Expedition: Discover a whole new world of adventure!
