Mechanics

Participation requirements

• Must have a 75% sortie win ratio.
• Must have 5 empty ship slots for new ships.
• Must have 20 free equipment slots.

Special Mechanics

1. The difficulty system first used in Spring 2015 Event returns: you can choose between Operation A (甲, Hard), Operation B (乙, Medium), Operation C (丙, Easy) or Operation D (丁, Very Easy) .
   • Choosing A or B requires certain HQ Level (HQ Lv 35 for B / 80 for A in Spring 2015 Event).
   • An important note to all Admirals intending to clear the event on Hard difficulty - further (new) conditions now apply:
     • When switching difficulty from any other difficulty to Hard, the map's debuff mechanism (where applicable) will be reset.
       • Switching between any other difficulties will not reset the debuff mechanism.
2. To simulate simultaneity of battles in different locations, Tag Conditions & Deployment Restrictions are employed.
   • Ships not already color-tagged will be tagged with the color associated with the map when deployed. This tag exists on all difficulties and is not reset on remodel, etc.
   • On Normal or Hard difficulty, ships must have either the same-colored tag as the map being deployed to, or no tag at all.
     • This requirement is sometimes waived on certain maps on Hard, or post-clear.
3. Beginning with the second map, difficulty progression rules apply.
   • In order to play a map on Hard difficulty, the prior map must have been completed on either Normal or Hard.
   • e.g., to do E-2 on hard, you must have completed E-1 on normal or hard.
4. The debuff system from Summer 2015 Event's final map, where certain nodes had to be attacked and other conditions fulfilled to reduce boss armor, will return.
5. Returning this event, the Vanguard Formation can be used .
   • This formation will organize the fleet such that the 3rd-6th/7th ships protect the Flagship and 2nd Ship of the Fleet.
     • In addition, the formation allows for ships to become more evasive in combat situations, especially with well-trained Destroyer.
     • This formation is also available only during the duration of the event.
     • The formation will be usable by both normal fleets as well as the Striking Force Fleet.
6. NPC Friend Fleets have been introduced into the game.
   • Friend Fleets act as another unit that appears in particular battles to help aid your fleet when attacking the enemy at the start of night battle.
     • NPC Friend Fleets are selected from a randomized preset list of ship.
     • Depending on who you have in your fleet can also influence who will be arrive to aid you in battle.
7. Enemy Radar Ambush Nodes have been introduced into the game.
   • Entering this node will result in your fleet facing off against an enemy fleet that will ambush and attack your fleet
     • Your Fleet will not be able to fight against the enemy Fleet.
     • By meeting certain conditions, you can evade these nodes.
8. Emergency Anchorage Maintenance/Repairs 【緊急泊地修理】
   • Both Akashi Kai and Akitsushima Kai will be capable of conducting emergency repairs; however, Akitsushima has more limited capabilities compared to Akashi.
   • See under Emergency Anchorage Repairs for details.
9. High-Altitude Abyssal Bombers that are resistant to all types of interceptors other than the new land-based rocket interceptors may also return this event.
