Second run of this game, in a poly bag with similar components to the original edition but a revised rulebook. In addition to the different cover, artwork captions and labels are set in entirely different typefaces to make room for the changed rules text, and the single-color counters are brown rather than red (though still strip-cut).
The same edition was also published in a small cardboard box rather than a plastic bag; this version has slightly different front cover typography, the added subtitle "Fighting Robot Game" in tiny type, and a blue background on the back cover. The counters are die-cut in two colors (red and blue) rather than the original brown and reverse-brown monotone. The rulebook is identical other than the addition of "second edition" on the frontispiece and the omission of ad pages (due to there being no cover for them to be backprinted upon).
