Trouble for HAVOC

Trouble for HAVOC is a supplement for the superhero role-playing game Superworld that includes three adventures.

Description
Trouble for HAVOC includes three scenarios that focus on a criminal organization called HAVOC: Statistics in all the adventures are given for Superworld as well as the other superhero games Champions and Villains & Vigilantes.
 * "Crisis at Calliente": The heroes must prevent the theft of a nuclear reactor by members of HAVOC.
 * "Return of the Elokians": The heroes must venture underground to confront a supervillain and his minions after HAVOC threatens humanity with an earthquake weapon.
 * "Fourth for Bridge?": The heroes race against a team from HAVOC to be the first to reach a downed spaceship in Antarctica. It is possible to play any team, or even play two or three teams in parallel if there are enough players. Pre-generated characters are proposed for each team but the players are free to substitute their usual characters.

Publication history

Reception
In Issue 71 of The Space Gamer (November-December 1984), Allen Varney commented "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."
