IDW and Desperado are releasing the DEADWORLD OMNIBUS for January release. It collects Requiem for the World (Image) and Frozen Over and Slaughterhouse (which was only in hardcover)...264 pages for only $19.99. This is where Deadworld was sort of rebooted so fans could join right in and not have to deal with the 50 previous issues of continuity. Diamond order #NOV10400...make sure you tell your store you want a copy so they'll be sure to order it. Also, here is an interview Gary Reed did that discusses it a bit more.
