World 1-3: 製油所地帯沿岸 The coast of oil refinery area

Stage Guide

The route from D to C is one-way only (you can not move from C to D). All compass spins in this stage are random. Keep trying if you're getting detoured to the maelstrom. Do note that F has heavy cruisers and the boss node has a battleship.

World 1-4: 南西諸島防衛線 The line of defense at Nansei islands

Stage Guide

After playing this stage once you may notice that standard aircraft carriers kind of hurt. For now your only countermeasures are to pick up a few heavy cruisers in this stage or 1-3 and train them up or just trying to craft battleships for doing the same just to push through with firepower and armor. Otherwise you can try to build your own aircraft carrier and put on fighters of your own to shoot down enemy aircraft. Note that this last suggestion will also help in completing the Akagi quest (A11 and B10).

World 1-5: 【Extra Operation】 鎮守府近海 Adjacent seas of the naval base

Stage Guide

This is a complete sub map. (Unless your fleet composition is wrong and you go off-course)

To reach the boss , a fleet of no more than 4 ships is required.

Having exactly 1 CVL/AV prevents being sent to node G from E, 50-50 otherwise. 

Having more than 2 CL or having more than 4 ships will send you from C to F (enemy carrier)

Being sent to node D requires more than 4 ships, as yet no D -> I (boss) route is known.

At least 1 BBV is highly recommended as it can equip seaplanes to hit subs while allowing you to enter the 2nd shelling phase.

Clearing this map gives you bonus medals which can be re-obtained every month.

The enemies on the map is scaled to your admiral level, meaning that the enemy may rank up when you hit a certain admiral level.
