A spin-off of Heavy Metal Magazine, these are the specials released throughout the years as a separate publication.
The numbering is confusing as some issues are numbered in the main series, and some in both. The indicia should be consulted to know if an issue is released as part of the main series or a special. The specials had a separate volume numbering, beginning in 1989 with The Venus Interface which is numbered Vol. 5, number 4.
The number of special issues that have been released is as follows:
- 1989: 1 Issue
- 1990 - 1991: None
- 1992: 1 Issue
- 1993 - 1998: 2 Issues
- 1999 - 2002: 3 Issues
- 2003: 4 Issues
- 2004 - 2007: 3 Issues
- 2008 - 2010: 3 Issues (New numbering, see note below)
- 2011: 2 Issues
- 2012 - Present: None
The issues are numbered by yyyynn, with y being the year they were released and n being the number for that year, for example the second special released in 1999 would be indexed as 199902.
The Fall 2008 Special and beyond combine with the main series and take on the volume numbering of the main series which is now subscribed to as a "nine issues a year" book. Later issues are again part of this series, or both.
