Revelations of Mars
This sourcebook expands Hollow Earth Expedition to a dying, conflict-ridden Mars filled with strange aliens, bizarre creatures, and vast wastelands. It supports adventures involving sky pirates, robot bodyguards, Martian nobles, and other extraterrestrial characters competing for survival, power, and earthly treasures. The book includes rules for creating robot and alien player characters, new and expanded psychic powers, Martian equipment and creatures, and details on extraterrestrial inhabitants and locations. These elements can support adventures on Mars or add an alien perspective to existing Hollow Earth games.
