Olympus is shaking to its foundations. Faith among the mortals is waning and with it the very power of the pantheon. Zeus is in a rage: "Hear me, gods! I command you to send forth my MONSTROUS pets. Make them rain from the sky and erupt from the underworld. We will rekindle these mortals' faith - through FEAR!"

Monstrous is a game of gods and monsters, fear and faith, dexterous skills and tactical combos.

Players are Greek gods throwing mythical monster cards from their hand onto a shared tableau of ancient Greek locations to gain as much 'Faith' as possible. But a strong guiding hand is not enough - cunning use of tactical monster and location powers is the key to gaining the most faith of all the gods, and the favor of Zeus.

During setup, a number of large location cards equal to the number of gods are arranged on the table - these are selected from 12 ancient Greek cities where the insolent humans cower. Locations have special powers and provide Faith when hit by Monsters.
