They Came From Beneath the Sea!
A tabletop roleplaying game inspired by the wonder, horror, thrills, and humor of 1950s science-fiction B-movies. Players portray war veterans, explorers, scientists, and working-class heroes defending coastal communities from alien forces rising from beneath the sea. Scenarios range from protecting a small town or liberating an infested cruise ship to commandeering an alien submarine and carrying the fight to the ocean floor. Multiple alien factions, including Enslavers, Invaders, Destroyers, Primordials, and Spies, bring conflicting motives and varied threats to each adventure.
