From publisher blurb: The Junkyard Dawg has been supplying weapons to the criminal underworld, and it's time that someone dries up that pipeline. Two Heroes You Can Hire seem up to the task. This pay-what-you-want download is an adventure supplement for the Sentinels of Echo City superhero RPG. Although you need those rules to play this adventure, the content is easily customizable to your superhero game of choice... which SHOULD be Sentinels of Echo City now that I think about it, so then you're all set.
