From publisher blurb:
"What if the creator of the first advanced version of the world's most popular RPG had the chance to expand his game?" That's the question that Adventures Dark and Deep™ attempts to answer. Starting with the 1st Edition as a foundation, it consolidates and streamlines rules, and adds new material, including around 1,000 monsters, including many new ones.
Adventures Dark and Deep™ is the ultimate game for enthusiasts of the 1st Edition.
This book contains nearly a thousand monsters and other creatures to bedevil your players. It is intended for use with the Adventures Dark and Deep™ Core Rulebook, but can be used with most OSR games with little or no modification needed.
Take your game to the next level with Adventures Dark and Deep™.
