Monsters of the Deep!
This roleplaying supplement expands a retro science-fiction setting with a bestiary of sea monsters and other aquatic threats. It provides creatures to use as minor antagonists, recurring foes, or the focus of entire adventures, including giant turtles, jellyfish, sea dragons, living coral, spies, and terrestrial menaces. The threats support both comedic and horrific play, depending on how the Director presents them, and are designed for use with the Storypath System.
