Since there isn't one, I believe:
1942 (Allies)
You are to defeat Yamaguchi, hold Midway for a certain number of turns and defeat Yamamoto as bonus objectives.
The Primary Objective is the defeat of the Japanese carriers.
Deploy Arnold on the carrier, Chuikov / best arty gen on your Katyusha, Cunningham on the stronger pre-spawned ship and Leclerc on the 3-hex inf.
Buy the 60 cash ship, 80 cash ship, 3X M1A1 and 3X Fighters. The point is to have more ships to fend off the enemy more easily, if you're new or less experienced. This sacrifices your ability to use air power to sink the troop carriers.
If you are experienced enough, buy the M1A1, 4-hex ship and 3X torpedo bombers. Place Cunningham on the 4-hex ship instead.
- Move Arnold away from your allies' path and enemy fire, but close enough to torpedo bomb the troop carriers or enemy ships.
- ONLY use your southern fleet to counter the troop carriers until they have been wiped out.
- Deploy anti-air / engineer Special Forces on your inf. The starting 3X inf MUST have anti-air Special Forces (preferably an M1939). The point is to resist the carriers' bombing and build more coastal forts.
- The Katyusha must ONLY be used to challenge troop carrier and be in range of an AA Special Force.
- Your other ships may circle north to assist your allies and sink any nearby landing crafts.
- Only when all landing ships have been sunk focus on nearby enemy ships.
The Japanese has two or three waves of landing crafts and two or three waves of ships. Resist these amphibious landings and assist your allies.
Your allies should be able to secure a naval victory on their own, but assisting them helps to clear out Yamaguchi (north centre) and Yamamoto (NW corner) quickly.
1945 (Axis)
Take Midway and defeat Nimitz on his 4-hex battleship.
Eliminate key ships to win.
Deploy Kesselring / Model / Student on the carrier, Ozawa / best admiral on the 4-hex battleship, Guderian on the 2X Panther reinforcements, Leeb on the reinfrocement 2X arty M40, Yamashita and Rundstedt on the reinforcement da 90/53 and 88MM Flak respectively.
If you feel an additional admiral is better, deploy Riccardi / 2nd best admiral.
Buy the sub, 40 cash ship, 3X torpedo bombers, carrier and 3X inf Reinforcements.
The AI's landing will fail, but they will draw enemy fire and potentially cripple the coastal fort gunners.
Send your southern fleet to assist in deleting the enemy vanguard to the south, then move your ships to the north.
Your other ships are to snipe at emerging enemy fleets to the north, attack crippled coastal fort gunners and seize the northern port. They can snipe at the 2X heavy tank gen to weaken him.
The carrier should use fighters to defeat the northern coastal fort gunner amd torpedo bombers to bomb threatening enemy ships.
Soon, you will receive landing troops. Land ASAP, defeat the remaining enemies and take Midway city. Keep your anti-air inf close to your troops.
Three airborne inf will appear. Swiftly defeat them, seize the remaining coastal forts and fire upon the carrier gen.
Use the 3X inf as Taurus Corps or Pioneer and build more coastal forts.
Assisting your allies earlier and drawing the enemy's attention helped your allies to cripple the northern fleets. This makes Nimitz the last target standing.
He should emerge from the SE. Finish him off.
