Top Cow Productions has announced that the debut issue of Hunter-Killer, a new comic series written by Mark Waid and drawn by Marc Silvestri, will have a cover price of just 25 cents.  Although the listing in Diamond's Previews catalog indicates that the book will be in black-and-white, it will be printed in full color.  The first issue introduces fans to Wolf and Ellis, two deep-cover agents who protect humanity against rogue superhumans.  Hunter-Killer #1 will also be available in a special limited-edition format with a sketch cover completely free to anyone who buys advance tickets to the Wizard World Texas Convention (Nov. 5-7).
