$1.59/whatever that is in pounds sterling
I'm sure the realism dorks will hate the way it looks, but it's awesome to me. It's samurai movie blood so it's fitting; Shogun 2 has never striven for a realistic look.
Also some are pissed that they're releasing a graphics feature for money, but A) it's so cheap, and B) there would apparently be issues with ratings boards if the DLC was officially part of the game (the DLC isn't even available in Germany, Switzerland and Austria) and this seems like a loophole.
Also you can get the Hattori clan now.
