From publisher blurb: "Today an amazing sight was evident in the downtown area. A dozen armed men, in green and yellow uniforms, staged a daring daylight raid on a chemical laboratory. This is the third in a series of violent acts by the group that calls itself VIPER." VIPER’S NEST is a scenario pack for CHAMPIONS, The Super Hero Role Playing Game. It contains three linked engagements all dealing with the actions of the notorious terrorist agency, VIPER. The engagements in this book will take the players from a first skirmish with VIPER agents to a final attack on their underground “Nest” headquarters.
