Check out those ESRB ratings: M, M, M.  I'm pretty sure this is the only week ever where three different M-rated co-op titles were released.  House of the Dead Overkill continues a fine line of co-op shooters, this time on the Wii.  And the Onechanbara games... well, what can you say?  Girls in bikinis, katanas, zombies, and a very large cowboy hat all mixed up into two quite unique co-op gaming packages.  You have to give them credit for creativity, for sure.  Provided below, for your ease of use, are handy links to Amazon.com for each game; purchases help support Co-Optimus!

Sometimes you just know the title of a game is going to sell it.  Carmageddon for example.  Yeah, I'll buy that.  Doom.  Yup, sign me up.  Blades of Steel.  I'll take two please. But when a game is called Onechanbara: Bikini Zombie Slayers we can't help but think they are going about this the wrong way.   Sure there's nothing wrong with women in bikinis slaying zombies.  In fact, we encourage it.  But something tells me the hardcore Nintendo fans of Mario and Zelda combined with the "non traditional" Wii-Sports gamers aren't your best target market.  You see, this is a Wii title.  Not a 360, not a PS3, not a PC...but a Nintendo Wii title.  Just think of the waggling possibilties for this one! All joking aside the game does promise players the ability to use the Wii-mote "swinging and thrusting into zombie enemy hordes."  And of course we wouldn't be talking about the game if there wasn't some promised co-op feature, which there is.  It looks like two players will be able to play through the story mode each utilizing their "own unique fighting style."  Bikinis optional.
