D3Publisher plans to release OneChanbara: Bikini Zombie Slayers for Wii and OneChanbara: Bikini Samurai Squad for Xbox 360 on 27th February.
These are action games starring Japanese girls not wearing many clothes. The word OneChanbara is a mix of meanings: a slang word for a young adult woman and a word for sword fighting.
Bikini Samurai Squad on Xbox 360 puts players in charge of three girls who cut and blast through hordes of undead baddies. There's co-operative play, or the option to switch between the girls in single-player.
There's a bloodlust meter to fill up in order to go berserk, weapon sharpness to monitor and extra clothes to dress up in. Famitsu scored the game an average 27/40.
Bikini Zombie Slayers on Wii is much the same, but with appropriate arm-waving controls. Famitsu scored this 26/40.
OneChanbara has historically been a Japanese craze, resulting in a recent movie, which you can find out more about over on the proper website.
