Rifts: Murderthon

From publisher blurb: Sunday! Sunday! Sunday! Juicer blood-sports are barbaric, but intensely popular, and it looks like one is coming to the Kingsdale area. A one-night special event, promising charity funds as well as a fantastic cash prize, draws juicers and other thrill seekers from all around. The Tomorrow Legion is directly invited to send a team, and the need to see what's really going on is great enough that our heroes are sent. What's really going on is something far, far darker than a merely deadly arena sport.
