Reception
Forrest Johnson reviewed Uncle Ugly's Underground in The Space Gamer No. 28. Johnson commented that "The dungeon will in short order chew up a party of the usual invincible solo-dungeon grads. Mostly traps and trickery, some fiendishly clever, some merely fiendish. But look out for the trolls with the zoot suits and violin cases."
