WHAT YOU NEED TO KNOW: For $5, you get six new characters as well as an adventure with map and standees. In addition, Galacticron (who was lurking in Hero Pack 1) is present here, along with a couple of other villainous types specific to the adventure. The adventure itself is a pretty basic affair, with Lady Omega ripped Galacticron across space and into the New Mexico desert, in hopes that he will destroy Earth. The kicker, of course, is that the PCs can't really harm him directly.
WHAT WORKS: I really dig a couple of the new villains, like the tech-stealing Ephemera and Sequence - a villainous powerhouse who has received a serious upgrade. I actually wrote a comic script with villains similar to the "space locusts" that are presented here (although mine were more like cockroaches), so that's rather cool.
WHAT DOESN'T WORK: The adventure could have used some editing, and while Lady Omega is TECHNICALLY a fully useable character...she comes across like the barest stereotype of a supervillain. Also, the "useable map" sure looks like it would be DRAMATICALLY off scale for the standees (and that's being generous with the definition of "scale"). I would have liked, say, a page of Lakmar Shock Trooper standees, myself...I mean, if you're going to use them, you're going to want a bunch of them.
CONCLUSION: A good product, with a great example of an adventure where the heroes HAVE to think outside the box, at least with the Galacticron problem. Despite the paper-thin characterization of Lady Omega, she does at least have a cool look and power set, so an enterprising GM can build from there.
