About this gameFull description from Steam
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 tenth round of releases, we offer "NOBUNAGA’S AMBITION: Soutenroku with Power Up Kit," the enhanced version of the 10th release in the series. With the theme "Retainers supplant Lords," for the first time in the series, players can play as a retainer officer. Based in Japan's chaotic Warring States period, this game portrays even greater battles for power than before. In addition, in foreign relations, different foreign strategies are introduced including encircling powerful enemies with multiple Forces, forming alliances between three Forces, and much more. Also with movement and battles progressing in real time, players experience more vividly the give and take of strategic battle. The power up kit adds 3 new scenarios, a database giving officer and castle introductions, and an editing function.
