In 1983, TSR published U3: The Final Enemy with the module code “U3”. It was written by Dave J. Browne and Don Turnbull, and illustrated by Dave De Leuw and Keith Parkinson. It consisted of a 48 page booklet and tri-fold cover with maps.
This conversion guide allows DMs to run the original module with Dungeons & Dragons (5th Edition) and provides a reference sheet for encounters.
This adventure is intended for 4 to 6 characters of levels 3-4.
To use this conversion guide you will need a copy of U3: The Final Enemy.
