Apparently Fall of The Samurai is its own game. It is not a Shogun 2 Total War DLC. It is basically gonna be like what Napoleon Total War was to Empire Total War. edit: Since it is its own game do you think Stalin should lets play it when it comes out in March? Personally I think yes. edit 2: Apparently its a standalone game and a DLC, You can get it as a game by itself or for Shogun 2 Total War.
I'm guessing in the game we'll have to eventually face off against troops armed with bolt-action rifles who are still using Napoleonic tactics
I could just imagine them fighting at Gettysburg and then all of a sudden Ronald Raygun comes down and shoots all the bastards down with his laser.
