Having recently celebrated its 30th year anniversary, Nobunaga’s Ambition is one of the longest running franchises for Koei Tecmo Games in Japan, and during its lifetime it has received high praise by an ever-growing fan base across an array of platforms. Now, its latest chapter, Sphere of Influence,marks the series’ return to North America after 6 years of absence.

Set against a backdrop of a fragmented nation, players take the mantle of a Daimyo, a feudal lord of the Sengoku era (15th-16th century Japan), and fight for the great ideal of uniting the war-ridden country under one rule, and become Shogun. Providing the choice to play as either a historical personality or a uniquely created character, Nobunaga’s Ambition: Sphere of Influence is both a full-scale historical simulation and a bona fide strategy title, and offers an extremely wide pallet of choices for the player to shape the world as they please.

Gamers will be able to download and play Koei Tecmo's historical strategy simulation Nobunaga’s Ambition: Sphere of Influence for free on Steam, from Thursday, November 5th at 10:00 AM PST until Sunday, November 8th at 1:00 PM PST.

The full game will also be available for purchase at a $10 discount from Thursday, November 5th at 10:00 AM PST until Monday, November 9th at 10:00 AM PST. Additionally, for those who are already in the midst of conquering the land and uniting it under their clan’s banner, KOEI TECMO will offer a sale for the nine available DLC scenarios, which will be discounted from $2.99 to $1.99 for the same period!

After 10:00 AM PST November 9th (Mon), the game and the DLC scenarios will revert to their original price.

The game is named after one of the most prominent and infamous figures of the Sengoku era (Warring States) of Japanese history, Nobunaga Oda. He fought to realize his dream of a united Japan and a new world. Though he fell before his dream was accomplished, he left behind a revolutionary legacy of castle towns and technological improvements, developing culture, modern warfare, and a new system of economics.

Nobunaga’s Ambition: Sphere of influence, centering around creating a realistic, dynamic, and dramatic playing experience, requires a high level of concentration and skill as players will need to master three key verticals in order to become a well-rounded ruler and successfully beat the game: Creation, Diplomacy and War.

• In ‘Creation’, players must strengthen their clan’s standing, and deal with everyday issues like building farms & roads, growing the economy, entering trade agreements with neighbouring fiefs, etc.
• ‘Diplomacy’ is a playground for cultivating diplomatic relationships, employing spies, creating alliances, gaining the loyalty of subordinate officers, and growing in strength via marriage, oaths of fealty and treaties.
• Finally, to succeed in ‘War’, players must train troops, level up officers according to the clan’s needs, fortify defenses, strategically position armies, and attack (or defend) to further their goals and grow their dominion.
