On April 10, Hex Games released Roller Girls Vs., which is an adaptable adventure scenario which recreates a roller-derby environment with monsters and danger tossed in.  Your roller girls could fight zombies, aliens, or just about anything else you care to throw at them.

The scenario is designed for use with the QAGS system.  It includes a summary of roller derby rules, information on character creation, popular character archetypes, a typical plot outline, and more.

It can be picked up for the low price of $4.99 in PDF format.
