Way of the Samurai 3 will be arriving on October 13th in the US. Agetec and UFO Interactive -- in charge of publishing the PS3 and 360 iterations, respectively -- officially announced the game's impending October arrival yesterday, as well as news of an iPhone iteration of the game currently available for free.
Sure, the iPhone version of WotS3 isn't much more than a side-scrolling brawler, but hey, it's free! Hopefully that can sate your samurai murdering urges for another month.
