I would think Jango should have thermal detonators considering his role in the movie. After all, it's not like the characters are a straight port from your old save. Unless someone knows differently for sure, I want to almost say that having an old save simply unlocks the additional characters in the second game. As for the other, when this game isn't randomly glitchy it seems to suffer from iffy hit detection. So far the glitches I've run into on my Xbox version seem to be relatively random and not too troublesome on a whole. I replay a level and it'll work the second time around. From some of what I'm hearing in this thread, I'm wondering if the PC version has worse glitch problems...ones that are more persistant in specific areas. If you've removed the protective cases around those targets and your energy is being maintained by R2 and despite constantly hitting the target (and the area around it) it still won't blow up, I'm not sure how many options you have. Supposedly, if you have selfdestruct, you can have R2 blow up near the target and that'll do the trick. At least it did for one player. Otherwise, the only other thing I can think of is to replay that level until it finally works without the glitch.
