A conversion of Shadowrun (fifth edition) setting and concepts to FATE Core, with some features based on other FATE-based games (equipment and purchasing from Bulldogs! and frameworks for critters and races from Dresden Files).
Some SR5 concepts have been omitted (eg. technomancer).
The designer recommends a working knowledge of the Shadowrun setting. As some of the concepts were borrowed from other FATE games he recommends having those books for reference as well (see above).
