From publisher blurb:
The A-OSM Model XI Manticore is well-respected throughout the Core Systems as a power armor that brings strength without sacrificing speed or protection! Popular among Meteor Baron militias, Planetary Tech-Kings, and Core System arena fighters, the XI Manticore is more than a match for anyone who can’t afford the advantage of real power. Or at least, that's what the advertising hype says.
Lily Compton, a well-known competitor in the DM (Death Match) circuit seems less impressed with its off-the shelf options. Her custom-mod Manticore trades flechette for plasma, and she's beefed up the armor plate in one arm. But it's still a Manticore, and she uses it to good effect!
This product includes background and Pathfinder Roleplaying Game stats for the stock Manticore, Lily's modified suit, and Lily herself (a human daredevil, a class taken from Anachronistic Adventures but with all the rules to run her as presented included).
