Originally published by WildStorm under its Cliffhanger imprint (founded by Madureira with J. Scott Campbell and Humberto Ramos), the series moved to Image Comics in 2001. The last issue, #9, was published in September 2001 and had a cliffhanger-ending that was never concluded, as #10 (scheduled for November 2001) was never released and Joe Madureira left the comic industry to pursue a career as a video game designer.
