While the otaku probably know what Queen's Blade is, the rest of you may not. For those not in the know, it's a super fan-servicey manga/anime where the female warriors wear ridiculous
clothing armor. More important is the one-on-one battles that they get into, which usually causes weapons to remove some of that clothing. It's basically a female warrior tournament with a horny twist. If you're rolling your eyes and writing it off now, know that the first episode has acidic long-ranged nipple lactation as a weapon. It's worth watching at least once!
Namco Bandai takes that formula and makes it a strategy role-playing game for the PSP, complete with the armor breaking formula that made the property so popular. Grid-like strategy transitions into 2D fighting. Regardless of what the true goal of the game is, you'll want to work to remove armor and be granted naughty CG scenes as a reward.
You can be certain that Queen's Blade: Spiral Chaos, dated "winter 2009," is not coming out in North America. So you'll have to call up your importer, perverts.
