To commemorate Kou Shibusawa's 35th anniversary, the "Kou Shibusawa Archives" will be opened in the Steam Store\. Here we will revive popular previously released titles\.    In this sixth round of releases, we offer "NOBUNAGA’S AMBITION: Haouden with Power Up Kit," the enhanced version of the fifth release in the series\.  Up to now in the series, warfare was focused on whole countries\. Haouden changes that focus towards individual castles\. Also, a Daimyo controls their officers through giving out rewards based on their achievements as they fight for total control of the Warring States\.
