Debuting with a cover date of August, 2005 the first two issues were released monthly, with the third issue delayed two months (Moore & Reppion cited delays in scheduling impacting the art production). Initially solicited release between October 2005 and January 2006, issues 4–6 were subsequently resolicited, and finally released throughout 2006, with cover dates between June and November. The TPB collection followed swiftly after No. 6 was released in both the US and UK, from WildStorm and Titan Books respectively.
