Participation Requirements
Check if you fulfilled these requirements if you can't sortie to event maps!
 * Must have a 75% sortie win ratio
 * Must have 5 empty ship slots for new ships
 * Must have 20 free equipment slots

Difficulty Selection

 * The Prototype Catapult item that is a requirement for Zuikaku/Shoukaku's second remodel will drop only on Medium or Hard difficulty settings in Area-E6. Even if completing all other maps on Easy, consider completing E6 specifically on Medium with your best fleet in order to obtain this item.
 * If you have limited resources, check the rewards for a map in advance to decide for yourself what is the most efficient way to get maximum resources while still reserving enough resources to complete Area-E7.

Ship-Locking
Ship-locking means that the maps are divided into multiple operations, and ships that you sortie to one operation could not be used on other operations. For example during the 2014 Event, a ship used on AL (E-1 and E-2) cannot be used on MI (E-3 and E-4).

This means that as you go further into the event, you will have less available ships for sortie. This is why it is recommended to have multiple ships properly raised for each ship type, e.g. using your best CAVs on early maps will lock it there, thus you'll have no more CAVs for later maps, which might even be required for branching.

There's two parts in the system: The Ship-tagging part and the Ship-locking part
 * Ship tag:The system will 'tag' your ship IMMEDIATELY AFTER you sortie your girls to the map. Depending on what map you send your girls to, they'll a get certain tag color.
 * E-7 is the only map that will not tag your ship with a new tag since it allows all ships with the exception of E-5 ships to sortie.
 * Tags are there to stay for the duration of the event and they can't be overwritten by another tag.
 * Tags are unique to the specific ship they're applied to, so if you have multiple Kagas, you can sortie one Kaga into E-2 and the other Kaga into E-3.
 * Ship lock:The system will 'check' your fleet to see if there are any ships with tags that don't match the map's tag. If there are no ships with conflicting tags, you're allowed to sortie that fleet.
 * However, the system will ignore conflicting tags if the chosen map difficulty is Easy. Meaning E-1/ E-2 tags are ignored if you're trying to sortie E-3 on Easy. On E-3 Medium / Hard, the ship locking restriction applies.
 * IMPORTANT: Ship locking does not apply to ships being used in support expeditions. Meaning your ships that are tagged with E-1/ E-2 can be used in support expeditions to help your fleet that is sortieing E-3

Ship-lock maps



Fleet Locking Table:

How to read the table: Each ship is given a color stamp in each area, ships with that color stamp can only sortie to an area of the same color stamp (e.g. blue ships cannot sortie to an orange area). Ships will be marked as soon as you enter the map.
 * To put it simple for E-7, every ship can be used except the ship that you sent to E-5.
 * For E-1 and E-2: REMEMBER! E-2 is a Combined Fleet! Your ships in E-1 can still be used in E-2 just remember to make it a combined fleet!

What ships are known for special branching?

 * E1: Kikuzuki confirmed
 * E3: Unconfirmed report for (Zuikaku + Shoukaku) or Shouhou(+CVL) or (Suzuya or/and? Kumano) or (Ryuujou + Tone)
 * E4:  (Kongou + Haruna) or (Kirishima + Hiei) confirmed, (Yuudachi + Akatsuki) or (Yuudachi + Harusame) or (Kirishima + Ayanami) reported, and (Yuudachi + Ayanami) and (2 out of 3 in Ayanami, Harusame, Akatsuki) are unconfirmed, with (Takao+Atago) rumored.  Ryuujou confirmed.
 * E5: Akitsushima +DD confirmed, unconfirmed report for Akitsumaru
 * E6: Fubuki + Furutaka confirmed, Ayanami + Yuudachi confirmed, Akizuki unconfirmed. However note that these pairings are ill-advised.
 * E7: Akitsumaru + CV leads to X/Y by fixing the D to H route. Akitsushima suspected to lead from D to H too?

E-7 Boss Special Mechanism
According to August 13th's tweets by game staff, there exist ways to make the E-7 boss weaker (see E-7 section in the page), but the effect will reset everyday at 00:00 JST. (However there are nothing visible to indicate the weakening) (The effect reportedly do not activate during the first two day of the event, however it is not validated) (It have been suspected that the weakening effect is actually increase critical hit effect of friendly ship but there are not enough evident to conclude it is really the nature of the weakening effect)

Note: at Aug29 00:00 JST (Aug28 15:00 UTC or 08:00 PDT), Rabaul server's weakening effect remain unresetted over day change due to server instability in the previous day. (So that If one in Rabaul server weakened the boss at 28th, they would not need to do that again in 29th)
