From the introduction:
The following is an official Fate Core rules supplement, created for Michael Cambata as part of a Fate Core Kickstarter commission. It deals with Very Large Monsters (VLMs) and the organizations that try to counteract them.
Very Large Monsters (VLMs)
They are mighty. They are unstoppable. They are the nightmares of humanity’s darkest dreams. They are … VERY LARGE MONSTERS.
From Godzilla to the Cloverfield monster, thousands of stories have been told of the few, brave souls willing to stand against giant monsters. Your Fate group can now join the legends, as they work to stop these giant beasts from devouring the countryside and burninating the peasants.
