Reception.
Allen Varney reviewed "Trouble for HAVOC" in "The Space Gamer" No. 71. Varney commented that "If you want a lot of genuinely interesting superheroes and villains for your campaign, "Trouble for Havoc" is certainly worth examining. If you hunger for subterranean action, you could do worse than the second scenario here. But mostly the adventures are file-and-forget."
