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 (, Hard), Operation B (, Medium), Operation C (, Easy) or Operation D (, Casual) .
    • Choosing Hard or Normal requires a certain HQ Level (HQ Lv 35 for B / 80 for A in Spring 2015 Event).
    • When switching from any "lower" difficulty to any "higher" difficulty, the map will fully be reset.
    • When switching from any "higher" difficulty to any "lower" difficulty, the map will stay in the very same state it was previously, with only +25% of TP/HP being reset on the current phase's TP/HP bar.
  2. 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.
  3. 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 a map or map's phase when deployed. This tag will be applied regardless of the difficulty and can't be removed by any measure before the end of the event.
    • One map can use multiple tags, usually separated by phases or fleets.
    • Several maps can share one or more tags.
    • On Normal or Hard difficulty, ships must have either the same-colored tag as the map/phase being deployed to, or no tag at all.
      • This requirement is sometimes waived on certain maps, mostly on the last map of the event where tags only matter on Hard, or on post-clear.
  4. Gimmicks are returning, asking you to accomplish certain requirements on a given map to unlock several things :
    • Boss debuff, from Summer 2015 Event's final map, where once you reach the "Last Dance" of the final boss of a given map, you can unlock its debuffed form.
    • Map phases, where some map areas need to be unlocked, like on 7-2 and 7-3.
      • Map areas can either be a path to the next boss, an intermediate path asking for new gimmicks, or a shortcut.
  5. It is possible that the Combined Fleet (CF), a fleet assembling both your 1st and 2nd fleets, will come back.
    • The CF is only available for your 1st and 2nd fleets, where the 2nd fleet can be merged with the 1st one in the Fleet menu.
    • The CF cannot be used in anything outside of event sorties.
    • 3 differents types of CF are available, depending on the map requirements and your current fleet setup.
    • CF with a flagship that carries a the Fleet Command Facility , will be able to make use of the Ship Evacuation mechanic.
      • The evacuation require an escort destroyer.
      • The evacuation consumes the ships' entire fuel & ammo reserves.
      • Only one ship can be evacuated per battle.
  6. It is possible that the Striking Force Fleet (SF), a fleet with seven ships will come back.
    • The SF is only available for your 3rd fleet, where an extra 7th ship can be added in the Fleet menu.
    • The SF cannot be used in anything outside of event sorties.
    • A SF with a flagship that carries a the Striking Force Fleet Command Facility , will be able to make use of the Single Ship Evacuation mechanic.
      • The new Striking Force Fleet Command Facility will become obtainable and useable via quest F64.
        • Note that the quest will consume the Fleet Command Facility and 2 Action Report in order to convert it into the new Striking Force Fleet Command Facility.
        • The evacuation does not require an escort destroyer.
        • The evacuation consumes the ship's entire fuel & ammo reserves.
        • Only one ship can be evacuated per battle.
        • The damage the ship suffered may become worse during the evacuation, but she will never sink.
  7. Returning this event, the Vanguard Formation can be used.
    • This formation will organize the fleet such that the 2 to 3 last ships protect the 2 to 4 firsts ships of the Fleet.
    • This formation is available for single and strike force fleets made of 4 to 7 ships.
      • The formation makes ships more evasive in combat, especially with well-trained Destroyers.
      • This formation is available only during the duration of the event, on the event's maps as well as on the regular maps.
  8. NPC Friendly Fleets (FF) may be introduced to the event.
    • FFs act as another unit that appears in particular battles to help aid your fleet when attacking the enemy.
    • If you want help from a FF, you may activate them via the "Friendly Fleet" button in the main menu
      • If activated, one FF is randomly selected from a preset list of fleets to help your fleet.
      • Depending on who is in your fleet influence which FF can help you, excluding the FFs containing ships you also have in your main fleet.
      • The FF will appear at the start of either day or night battle, depending on the node.
    • FFs are usually available sometime after the start of the event, to help Admirals facing difficulties clearing the maps.

    • 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.
