The magazine was released on a roughly bimensual schedule, with 5 to 6 issues per year. Each issue usually focused on one particular anime or manga, dedicating up to one third of its page content on related synopsis, character and mecha presentations.
Mecha Press was originally started as a sister magazine to Protoculture Addicts, the oldest anime and manga magazines in North America. Its name derives from its main focus, mecha, although the content also covered characters, stories, toys, games and scale models.
The first issue, a red duo-tone test called issue #0, was published in 1991. Issue #1 officially launched the magazine the next year. Issues #1 through 6 had an oversized format similar to a tabloid newspaper. From issue #7 and onward, the magazine was shrunk to a more standard size, but gained a color section.
When the design team, Dream Pod 9, started focusing exclusively on games, the magazine was cancelled with issue #17. The remaining unpublished content was then merged into Protoculture Addicts magazine. Archive issues are available as PDF e-books from the publisher.
Starting with #2, each issue has one main topic and several derivative ones. The following abbreviations are used in the listing to save space: Basics of Mecha Modeling - BoMM; Battletech - Btech; Engineering Outlook - EO; Heavy Gear - HG; Heavy Gear Fighter - HGF; Jovian Chronicles - JC; Mobile Suit - MS; Mekton II - MkII; Questions & Answers - Q&A.
