The exciting new Officer Play mode also affects the way battles are experienced, as players will have the opportunity to witness thrilling and historic battles first-hand through the eyes of an officer. Aiding in victory or defeat, every command made will affect the outcome of battle, and bonuses are awarded for successful deployment of a new strategy. This installment also introduces Combat Quests: extra missions that appear during the course of battle and provide extra rewards upon completion. These dynamic objectives change based upon the tide of war and allow for more in-depth and dramatic battle experiences.
Players will be able to exploit the entire breadth of strategic options available to them in Nobunaga's Ambition: Sphere of Influence – Ascension with the introduction of two new types of warfare: Siege and Naval battles. Full-scale Siege battles create strategic situations that allow blockades to be deployed as a defensive mechanism, as well as the use of tunnels and cannons to gain an advantage over a defending opponent. Naval battles provide the option to carry out skirmishes and strategic blockades on oceans to overcome the enemy from every angle.
