Sega has announced a new standalone expansion for Total War: Shogun 2, called Fall of the Samurai, that introduces new units, a new campaign map, and new content to the acclaimed tactical strategy title. As you can see in the trailer above, the biggest new addition to the title is the inclusion of more modern Western troops and weapons, including a Gatling gun, as well as British and US troops and marines.

There are six new playable clans to deal with the American, British and French foreign powers, and there are 39 new units in total (including ten new ships), as well as four new historical scenarios to play. Multiplayer is also getting revamped, as are a few other gameplay mechanics, including siege battles.

Sega and The Creative Assembly plan to have the title ready to go in March of next year. If the trailer is any indication, the samurai should probably start making bulletproof armor right about now.
