While Samurai were very amazing warriors in their time, not much can stand in front of a Gatling gun and not fall over dead. Sega has revealed that they are currently working on a new standalone expansion for Total War: Shogun 2 and they are calling it Fall of the Samurai. This expansion will introduce a number of new units, a new campaign map and plenty of new overall content.
In the trailer below you can see that more modern Western weapons and troops have been introduced into the title, including British and US troops as well as their fire arms. There are going to be six new playable clans and 39 new units with ten of them being new ships. Besides that there will also be four new historical scenarios added in to help expand the experience. Currently Sega is aiming for a release in March of 2012, so it may be best to take this time and give your fond farewells to the samurai.
