Played some more Queens Blade. Four characters in my party now (including one male, who is a healer and is totally useless in battles). I've got a lot more figured out now, although I'm still not getting the best ways to target body parts. Certain enemies are pretty stupid, but others will block multiple hits to the same area. You can completely annihilate others if you have support, which is done by placing one character next to another (although so far only Leina and Tomoe can do this...the two original characters can't yet). It didn't happen on any male enemy characters (I WONDER WHY), but beating the shit out of female enemies allows you to target another body part for extra damage, which results in various shots of them half-naked. No surprise given the source material!
Does this pretty much sound exactly like SRW? I downloaded one of the GBA OG ROMs, but the limited animation and story were kinda boring. I'd definitely rather have the licensed mechs.
