Reception
Tony Watson reviewed Shadows/Annic Nova in The Space Gamer No. 29. Watson commented that "Overall, Shadows/Annic Nova is an interesting supplement for Traveller. The situations it describes should provide the players with a number of intriguing adventures, and even if the settings described aren't used exactly as given, they should provide an enterprising referee with enough ideas to set up a similar game scenario on his own. While Shadows/Annic Nova can easily be omitted from a player's Traveller collection, the dedicated referee will not want to be without it."
