From publisher blurb:
HIDEOUTS & HOODLUMS Supplement V is finally here! This is the first time H&H, the premier retro comic book RPG, has teamed up with a retro comic book publisher, Big Bang. Big Bang founders Gary Carlson and Chris Ecker have reviewed and endorsed this product, in addition to offering invaluable feedback and access to their archives.
Though not a stand-alone RPG product, Supplement V: Big Bang gives you everything you need to adapt H&H for a home campaign set in the Big Bang Comics universe, from the 1930s to the 1970s, including: revised rules, new powers, spells, and stunts, new mobsters, new trophies, a Big Bang gazetteer, campaign advice, stats for the major Big Bang heroes and villains at various points in their careers, a comprehensive timeline for all published stories within that time frame, and a comprehensive bibliography of published stories. And lavishly illustrated with art from the comics!
