Tips

This map is mostly randomized on the path you take, with few notable exceptions that should be considered:

  • Avoid bringing too many (F)BB(V) and CV(L).
  • A well-balanced fleet is recommended for tackling this map.
  • While dedicated ASW setups are not necessary, mixed ASW set-ups can be considered for DDs.

Recommended Fleets

  • 1CL, 2DD, 3AV/CLT/CA(V)
  • 1CL, 2DD, 2CA(V), 1BB(V)/CV(L)
  • Route = Random :
    • A B D H J
    • C F D H J
    • Will always fight 3 battles pre-boss but allow stronger ships that help withstand enemy shots compared to the light comp.

  • 1CA(V), 1CL, 4DD
  • Route = Random :
    • A B D H J
    • C F H J
    • Cheapest composition, but requires high-level CL and DDs as they need to dodge the closing torpedo if they didn't disable all of the enemies CAs, CLs, and DDs in advance.

  • 2CV(L), 1CLT, 3XX (XX can't be (F)BB(V) or CV(L))
  • Route = Random :
    • A B D G J
    • C F D G J
    • Heaviest comp, with a slightly harder pre-boss, as you will always go to Node G where Battleship Ta-Class are awaiting, in exchange, you get to bring CV(L)s for opening airstrikes and more firepower on the way to the boss and at the boss node itself.

Resource Nodes

B is a "Normal Resource Node" rewarding fuel  .
