This game is weird but has a cult following in Japan and was released on the PS2 originally. Now it makes it's way to the US for the XBox 360 and Wii.
Take the fast-paced crowd clearing combat of Dynasty Warriors set in modern day +
Zombies and the Undead +
Nearly naked chicks (and sometimes naked I'm sure) with guns and katanas, literally cover them in blood +
...and you have Onechanbara- Bikini Samurai
I'll get it because of it's low retail price ($40) and I like the crowd clearing genre.
I'm surprised a game like this is going to the Wii though.
