Core Mechanic

Roll four Fate dice and add a skill rating, then compare the total against a fixed difficulty or an opponent's roll on the adjective ladder. Matching the opposition is a tie, beating it by one or two shifts is a success, and beating it by three or more is a success with style. Spend a fate point to invoke an aspect for +2 or a reroll. Accepting a compel earns a fate point in exchange for a complication.

Best For

Groups who want to play Action Scientists in pulp adventures against super-science conspiracies, jumping between eras of a century-long secret history. Its Brainstorms suit tables that like solving mysteries together during play.

Highlights

Brainstorms turn a mystery into a group procedure: each winning roll adds a fact as an aspect, and the final hypothesis must build on every fact. Invention rules build a gadget from a function aspect, a flaw aspect, and stunt benefits, then charge for it in narrative catches like rare materials rather than money. E-Z No-Math creation starts a character from a concept and three rated modes, so players can make characters on the fly and fill in aspects and stunts during play.

Considerations

Custom weird characters take longer to build, because modes and skill improvements are bought from a 30-point budget instead of picked from the E-Z options. The campaign rules assume the PCs belong to a faction, so a group playing freelancers has to build its own organization or run without the faction support and advancement rules. A Brainstorm's winning hypothesis becomes the truth of the situation, so a GM cannot count on a planned explanation for a mystery surviving play.
