Way of the Samurai 4 will let you create a ronin and explore post-isolationist Japan starting August 21 in North America. The PSN-exclusive PS3 game will be available for $39.99.

While the premise is all about joining up with the shogunate, the isolationists, or the new immigrants, and experiencing the power struggles between the three groups, we're fairly confident the moment-to-moment gameplay is going to have more to do with swordin'.

Speaking of which, you'll be able to upload your created character for distribution in others' games, as a wandering, AI-controlled assassin. Other players' characters will roam your game, offering up items to anyone who can defeat them.
