Tips

  • This map requires to use specific compositions to prevent being thrown into dead ends or having too long routes.
  • Node D is a regular maelstrom node, and F is a strong maelstrom node with a 25% chance to wipe all of the remaining fuel for fleets with less than 2 radar-equipped ships. It is therefore recommended to bring at least 2 radars for routes going through F.

Fleet Notes
Gives the shortest path to the boss node, only facing one battle and a maelstrom node.

However, such a light fleet might have some issues passing the only preboss node and winning the boss fight.

Resource Nodes

E is a "Normal Resource Node" rewarding bauxite  .

K O are "Special Resource Nodes" rewarding respectively large furniture box  , and medium furniture box  .
