William A. Barton reviewed The Vanished in Space Gamer No. 70.[1] Barton commented that "The Vanished could provide a good evening's entertainment for your ST play group – and the Deepspace Facility plans could suggest many more to a clever GM."[1]
Frederick Paul Kiesche III reviewed The Vanished for Different Worlds magazine and stated that "All in all, Messrs. McLimore and Poehlein did a fine job on The Vanished. In fact, I would say that this adventure could stand with the best of the original television episodes, although it probably would have given the producers headaches to build FDR#39! Only one problem cropped up-there are several glaring typographical errors in the adventure booklet. FASA should definitely take better pains to ensure accurate copy; what is the sense of keeping a publishing deadline if nobody will be able to understand what you have printed? Other than that, a fine job. I look forward to seeing more work from these gentlemen."[2]
