Reviewer Anders Swenson reviewed the D1–2 Descent into the Depths of the Earth compilation in 1982 for Different Worlds'' #21.

He was perplexed by all of the creatures found in the grand cavern area originally found in module D1: "All these creatures are apparently expected to do nothing but sit in their caves and wait
