Reminds me of Bloodrayne somehow. Or the movie Grindhouse, with that lady who had a gun for a leg. And I thought P.N.03 was about being stylish while blasting things to smithereens. Er, well, Viewtiful Joe was also about being stylish.
Idea sounds cool, yes, but I just have my doubts that it's going to be any good because the concept's so high up in the air. Extreme action scenes? Feet guns? Attacks that gradually make the woman more nude? Press a button for extra sexiness? Sounds gimmicky to me.
And I hear "this is gonna be the best game ever" bandied around a lot in response to games with ridiculous concepts, or starpower (imagine a game with Chuck Norris and Samuel L. Jackson in it), or games that look so bad as to be good. I'm pretty sure the label was applied to that DS/PSP game "Napoleon Dynamite: The Game" too.
