Paradox Interactive today released the second video developer diary for their newest internally developed game, Sengoku, a Grand Strategy title for the PC set in 15th century Feudal Japan. In Sengoku, you play as the head of an illustrious Samurai family. The year is 1467 and civil war has broken out. The authority of the Ashikaga Shoguns has collapsed and it is every man for himself in the provinces. Honor and duty vie with survival in the delicate dance of power, conquest and betrayal as you attempt to unite the land of the Rising Sun through a combination of deal-making with foreign powers, sending your powerful samurai armies into battle against your enemies, and unleashing shadowy Ninja clans under the cover of darkness to assassinate your rivals. Sengoku will launch in Q3 2011.
