List of New Contents

New Chapter
Chapter 16 (Normal Mode for Chapter 16 will be permanently available after the next maintenance. Fujinami will be obtainable in Chapter 16. In this chapter, the highest level of enemy ships is approximately 132, and “Clearing Mode” has not been opened yet. Character level caps will not be raised.)
New gameplay added
[Support Fleets]
※Support Fleets can be configured in the Formation interface. They do not participate in battle and do not contribute towards Air Superiority or Recon values.Your SS, SSV, and IXS ships can be added to a Submarine Support Fleet. During battle, they provide torpedo support for allies.
※In Chapter 16, the Submarine Support Fleet will launch a submarine attack against the enemy fleet before the surface fleet engages in combat. The result of this action will affect the Concealment values of both allied and enemy fleets.
※Note: 10 Oil is consumed each time the Submarine Support Fleet is deployed. Doing so will not affect Morale, and does not grant EXP or Affinity.
[Fog of War]
※While under the effects of Fog of War, the size and type of enemy fleets will be hidden. The initial visibility level of a surface fleet is determined by its AVI stat. Its visibility range determines the area in which Fog of War can be temporarily dispelled.
※Enemies will receive buffs based upon the number of tiles obscured by fog of war. Increasing the visibility range of your fleets to weaken this effect. Each time an allied surface fleet defeats an enemy fleet, its visibility level will increase by 1. When the combined visibility level of all surface fleets reaches a certain amount, the enemy boss fleet will be revealed.
[Land Bases]
※There are three types of enemy land bases. Enemies will be able to provide varying degrees of air support based on the number of land bases present on the map. Neutralizing enemy land bases through strategic use of airstrikes will reduce their air support strength.
※Airstrike：After forming and deploying an Air Support Fleet, you will be able to launch an airstrike (up to 2 times) on a selected tile via the Strategy menu.This airstrike deals percent HP damage to enemies and destroys enemy land bases within the attack range as well as the visibility range, but does not work against enemy boss fleets.
