Active Exploits is a diceless set of role-playing game rules by Precis Intermedia Gaming. The core rules (which contain no setting) are distributed for free as a pdf file, or for a fee as a printed book. There are a number of published game settings and official game conversions which use these rules.
The system is considered innovative, but more in common with GURPS and Unisystem, rather than other diceless games such as Amber and Nobilis. The game has options for freeform and live action role-playing, as well as for converting the game to other systems. Ample conversion rules allow the adaptation of the engine to a number of commercial systems.
