The story ran across 4 issues, each featuring one of the major titles in the Wildstorm Universe at that time: Sleeper, Stormwatch: Team Achilles, Wildcats 3.0 and The Authority.
Each issue of the overarching storyline, which Jim Lee described as a "stand alone 4 part mini-series event", is a one-shot focusing on one of the four different groups and created by their respective writers and artists.
In Coup d'Etat, Tao places a device in the hands of the U.S. Government that allows them to enter the Bleed, where it exploded, damaging a vessel of an alien race and starting an interdimensional war.
The crossover had important consequences for the Wildstorm Universe with the Authority taking control over the U.S. Government and Stormwatch: Team Achilles being forced underground.
For Stormwatch: Team Achilles and Wildcats 3.0, most of these consequences could not be explored as both series were cancelled shortly afterwards.
