From the back cover:
Henchin’ Ain’t Easy!
But it’s not very fun, either. And the pay is horrible, too. Still, someone’s got to clean the carbon deposits from the planet destroying laser. And those pit traps aren’t going to dig themselves. When the super hero or super spy shows up, you’re the one who has to buy the evil mastermind enough time to arm the self destruct device. And how do you expect the captain to know just how deadly that alien creature is if there isn’t someone there to be brutally slain by it first?
So, if you’re tired of being the protagonist, or even the antagonist of your story, this is the book for you. Inside you’ll find all the rules you need to play the fodder, minions, thugs, lackeys, henchmen, and other assorted types of Non-Essential Personnel.
