**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.
 +
 
 +
*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.

 +
*To simulate simultaneity of battles in different locations, '''[[Ship Locking|Fleet Tags]]''' 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.

|-|Fleets=
 +
*The '''[[Combined Fleet]]''' (CF), a fleet assembling both your 1st and 2nd fleets, may 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 different types of CF are available, depending on the map requirements and your current fleet setup.
 +
** CF with a flagship that carries a the '''{{EquipmentLink|Fleet Command Facility}}''', will be able to make use of the '''Ship Evacuation''' mechanic.
 +
*** The evacuation requires an escort destroyer.
 +
*** The evacuation consumes the ships' entire fuel & ammo reserves.
 +
*** Only one ship can be evacuated per battle.
 +
 
 +
*The '''[[Striking Force Fleet]]''' (SF), a fleet with '''seven''' ships, may 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 '''{{EquipmentLink|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 [[Quests#F64|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.

** This formation is available for single and strike force fleets made of [https://twitter.com/KanColle_STAFF/status/930623111862435841 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.
 +
 
 +
|-|Friendly Fleets=
 +
*'''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 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.
