In the June–July 1978 edition of "White Dwarf" (Issue 7), Fred Hemmings found the game "simple to learn, and yet at the same time is so full of good ideas and potential player skill." Hemmings admired the "beautifully produced" game components, but wished that there was more than one winning objective — although he did note that using the two available expansions resulted in 35 alien races to choose from, giving a potential for more than a million combinations. He gave the game an overall rating of 8 out of 10, saying, "What makes this game is the aliens —they vary from good to excellent, and so does the game."
