Did the offerings at your local game store for Free RPG Day leave you cold, or they'd run out of what you wanted, or you just can't get to a gaming store today?
Then Exile Game Studio has you covered.
A free download of its new starter adventure for Hollow Earth Expedition (HEX) has been posted on Exile's website: Markawasi - Monuments of Mystery
In 1936, the characters are in a deadly race to reach the mystical Forest of Stone, high in the Peruvian Andes, and must overcome Nazis, mummified dinosaurs and the puzzling enigma of Markawasi if they’re to uncover its secret portal to the Hollow Earth.The 15-page adventure includes quickstart rules for the Ubiquity system, and four sample characters... and that's all need to get playing.
The Ubiquity rules mechanics work with any type of die (as long as it has an even number of sides) or even coins if you can't lay your hands on any dice.
