In the August 1980 edition of "The Space Gamer" (Issue No. 30), Tim Byrd gave a favourable review, stating that it "successfully combines fantasy with SF" and that it was "extremely fun to play [...] one of the best modules TSR has published". Six issues later, in the February 1981 edition of "The Space Gamer" (Issue 36), Kirby Griffis noted that the adventure was full of "surprises and new monsters", and felt that its one drawback was that Gygax presented standard "D&D" monsters as natives of other planets. In summary, he found it interesting and "full of spice and flavor", and recommended it to anyone interested in "something new" or wanting to include science fiction in their "D&D" game.
