It’s simple mathematics. When you double the bikinis, you double the fun.

D3Publisher has posted revealing first details of Onechanbara: Bikini Zombie Slayers, the upcoming and self-explanatory Wii action game.

The game will “take full advantage of the Wii Remote” for immersive attacks on zombie enemies, offer both single player and two-player cooperative play, as well as several modes and combat mechanics.

And, of course, half-naked chicks.

No specific release date has been announced, but if busty zombie exterminators clad in skimpy bikinis and wielding katana blades are your thing, you should be in blood-spilling heaven in early 2009.
