Evaluation

Nobunaga's Ambition: Kakushin with Power Up Kit launched on June 25, 2015 as a complete, enhanced edition of the 12th entry in the Nobunaga's Ambition series. The store description presents it as a finished product — the base game bundled with its Power Up Kit — with no mention of planned expansions, future DLC, or ongoing content development. Developer activity after launch was limited to two minor bug fix patches, the last of which was released on October 6, 2016 and added windowed mode support. There have been no developer communications of any kind since that date, no DLC listings, and no roadmap or announcement of future content. This game was released as a complete package and has received no post-launch content beyond maintenance patches.

About this game

An extension of the 12th release in the Nobunaga’s Ambition series, Nobunaga’s Ambition: Iron Triangle, has appeared at the Steam Store as Nobunaga’s Ambition: Iron Triangle w/Power-up Kit!
This game is the first in the series to employ a single 3D map for the game to play out on. On this map in 3D, castles and towns are built and developed, attacked and defended across Japan and grand naval battles take place on the Inland sea.
In addition, over 80 techniques can be developed using the “Tech Innovation System” and then used in battle to win a strategic victory.
Furthermore, the power-up kit brings you a variety of new and powerful additions, including the Foreign technique, in which using special goods for trade is the key, and many more.
