This is the first edition of the stand-alone Star Hero RPG produced by Hero Games. This was the last product from Hero Games before the release of 4th edition.
Back cover text (excerpt):
Star Hero uses the Hero System, which is easy to learn and quick to use. The Hero System allows you to create characters exactly as you imagine them -- either directly from science fiction or from your own imagination. Star Hero is clearly written to introduce even novices to role playing games, while the open-ended Hero System offers a challenge to even the most experienced game players. Taken together, all Hero System games interlock to form an unequaled gaming environment.
