Reception
William A. BartonreviewedLomodo IVa in The Space Gamer No. 48. Barton commented that "All in all, Lomodo IVa, while having its points of interest, seems the least inspired of any of Group One's adventures thus far. If you haven't thought much of their past products, you'll really hate this one. Unless you're a collector of all Traveller items or are hard up for a place to adventure, pass this one by."
