The original digipaks had slightly different artwork, most noticeably a different barcode on the front cover, and different colouring within the words "Fear Factory". The digipak was re-released in 2003 with all bonus tracks mentioned above, but with the new Roadrunner Records logo on the front and back and different lettering on the spine. This version is not limited, but has since been replaced by the remastered edition detailed below. In all, four different digipak versions of the album are available.
