From publisher blurb:
An Adventure for Use with Supers! Revised Edition
It’s All Hallow’s Evening and there is sure to be mysticism and mayhem. It’s not always one master scheme the heroes must deal with to protect The City, but the chaos of multiple events. The heroes must face multiple challenges, sometimes with little or no rest in-between as they try to bring order to a Halloween night that is quickly spiraling out of control.
Havoc on Halloween is a series of five encounters intended to give your heroes an opportunity to face-off against varying challenges. It also includes five complete super villainous write-ups, each fully illustrated, with backgrounds, and additional story ideas to include them in future adventures within your campaign.
