Introduction

• You can bring ships that has already been tagged for E-1, E-2, and E-3.
  • However ships that has not been deployed to either of the previous maps before going into E-4 will gain their own shiplock tag, therefore preventing them from sortieing to these maps if you had completed them on Medium or higher. Source.
• This Map contains multiple New Type of Night Battle nodes
  • Some Night Battle nodes will require you to face the enemy fleet in Night Battle at the start, but then be dragged into fighting them in Day Battle after the Night Battle Phase is over.
  • Support expeditions will attack the enemy fleet before the night battle.
  • LBAS will only attack when the night battle has transitioned to day battle.
• Please be advised this Map will require a certain number of Historical Ships as listed below.
• The Boss Node of this Map is hidden, and you will be required to go through Two Phases of fulfilling certain requirements to reveal the Hidden Boss node.
• This Map requires you to defeat Two different Bosses. Night Strait Princesses as the Mid-Boss, and Entombed Anti-Air Guardian Princess as the True Boss.
• At the boss node, you will fight against the Abyssal Combined Fleet at night.

  • The attack order is determined by range for both shelling phases
  • Your fleet can target any ship from either Abyssal main or escort fleet during both shelling phases.
• You will have access to 3 Land Base Aerial Support, where only 2 may be used for Attacking.
  • Even in Easy mode, your LBAS will be attacked by Enemy Air Raids.
  • Note that if Entombed Anti-Air Guardian Princess was the sole remaining ship that survived the night battle, the LBAS will suffer heavy losses as her very high AA is applied on all LBAS bombers.

Unlocking the Hidden Boss Node

Notice

The following are not 100% confirmed as of this time, where some of the requirements listed below may turn out to be actually not required. Please follow this at your discretion

Phase 1: Opening the Z Nodes

• S-Rank node U
  • You must use a Combined Fleet of Surface Task Force.
    • A certain number of Kurita Fleet Members are required to take the shortest and safer route.
      • Easy: 3 / Medium: 4 / Hard: 7
    • If you take any slow ships, you will be off-routed to node J, which contains New Submarine Princess.
    • You may only take up to 3 Battleships, or otherwise you will be off-routed to Node H from G.
• Reach node X
  • This can be done by sortieing a 7-Ship Fleet only composed of Ships who has the E-1/E-2 Ship Lock Tag.
    • Using any Ships with a Different Tag, or not having any Tag set onto the ship will result in you starting from Start Point #2 in the South instead.
      • This rule applies on Easy Mode as well
    • Using any CV(L) will cause you to off-route.
• Obtain Air Superiority (AS) in node N and V (Not required on EASY mode)
  • This can be easily done by sending your 2 LBAS available for Sortie full of Fighters to each respective nodes, and bringing ships with Seaplane Fighters.
  • Node N can be reached a fleet which includes the Nishimura Fleet Members.
    • Easy: 3 / Medium: 4 / Hard: 6
    • Using any CV(L) will cause you to off-route from node I to K.
  • Node V can be reached using a fleet of E-1/E-2 Ship Lock Tagged Ships.
• Obtain a Perfect No-Damage Defense from Enemy Air Raid Attack on your LBAS  (HARD only)
  • This may easily be done by putting only Fighters and/or Interceptors on your LBAS and set to Air Defense mode, and just travel around the map while using multiple Submarines, until your LBAS becomes ambushed by Enemy Air Raid.
• Obtain A or S-Rank in node Y
  • This can be done very easily by using multiple Submarines to avoid majority of the battles.

Phase 2: Opening the ZZ Nodes

• Obtain Air Superiority (AS) in nodes Z1 & Z2
  • Both nodes have Enemy carriers with very high Air Power. You are recommended to bring CVLs equipped with your best Fighters, CAVs equipped with Seaplane Fighter.
  • You are also recommended to send your LBAS to each nodes loaded with Fighters so that you may shred down the Enemy Air Power so that you will gain Air Superiority easily.
• Obtain A-Rank or higher in node Z4.
  • This can be done easily while on-route towards Z6.
• Obtain S-Rank in node Z6
  • The path to this node is very difficult. Use of Support Expedition and LBAS focused to this node is highly recommended.
    • You may also divide your LBAS to help you in both node U and Z6 respectively.
• Obtain A-Rank or higher in node Z8
  • You may use your E-1/E-2 Green Tagged Fleet to go into Z8 from the North in Point#3.
• S-Rank node Z9
  • You may only enter Z9 through a Fleet which includes the Nishimura Fleet Historical Ships.
• Obtain Perfect LBAS Defense against Enemy Air Raid.
  • Required for both MEDIUM & HARD MODE.
  • Same as before, place all your LBAS into Air Defense Mode with your best Interceptors and Fighters.
