A solitaire adventure for Monsters! Monsters!
From the back of the book:
The Toughest Dungeon in the World is a solitaire adventure that can be played with Monsters! Monsters! or Tunnels & Trolls. Written by Ken St. Andre it was first published in 1980 by Judges Guild. Now, 40 years later, Ken has updated and enhanced this classic solo adventure, bringing it back to life in new and exciting ways. Artists Phil Longmeier and Steven S. Crompton have enhanced this solo with new illustrations and graphics more suitable for this wild monster-mash solitaire adventure.
Ken St. Andre was inducted into the Origins Hall of Fame and is one of the last standing creators of the first generation of role-playing game designers still working on the classic games he created. This new expanded edition is now 48 pages long and will keep any player busy for a lot of adventure in caverns and tunnels deep below Trollworld.
What makes this the toughest dungeon and what or who is the Lord of Shadows?
It dwells in the depths waiting for you. Will you avoid its power or be corrupted by it?
