The battles of Shogun 2 involve large-scale engagements between armies that meet on the campaign map and can take place on land or on water. The developers proclaim they are paying particular attention to re-designing the naval and siege battles appropriate to the new setting. In contrast to European castles and forts, the castles in feudal Japan had multiple tiers, and thus the siege battles in the game put less focus on wall defences but more on courtyard brawls and tactical maneuvering. Also, the players will fight naval battles with unique Japanese ships resembling "floating castles", and take into consideration melees on ships, arrow fire, coastal terrain, and other factors.
