From the publisher:
Based on d20 Modern, Bad Axe Games' Grim Tales is the high adventure, low magic campaign sourcebook for fantastic roleplaying in your favorite pulp genres, from the dawn of Atlantis to the apocalyptic future of a dying planet. The Players' Section contains all the rules for character creation, including hundreds of feats, skills, talents, and equipment arranged by genre and/or time period. The Game Masters' Section is presented in true tool-kit fashion, allowing the GM to pick and choose from a wide variety of campaign trappings-- Spellcasting, Horror, Technology, Vehicles, Firearms, Cyberware, and more-- and to integrate them seamlessly into any campaign genre. The book also includes background material detailing the primary arch-villains of Grim Tales: a collection of evil overlords and their minions that can plague humanity (and challenge the PCs!) in any time period or genre.
Grim Tales brings to fruition Bad Axe Games' founding principle to provide 'games with grit'.
