Now you can play the IJN campaign! Note it is recommended you play the US campaign tutorial before playing.

Gameplay:

• Added the Japanese campaign.
• Added the Akizuki-class destroyer, Agano-class cruiser, and I-400-class aircraft-carrying submersible.
• Airfield AI will not launch non-ASW aircraft against submersibles.
• Manually-fired weapons are not deselected upon firing.
• Setting a port's supply priority to "none" or "surplus" will cause any cargo fleets with supplies heading there to pick a new destination.
• The player’s submarines may safely retreat on the bridge, if in a deep dive.
• Ships ordered to bombard a port with their guns stick to their longest gun range.
• Gun accuracy against a single target increases more slowly.
• Time speed is retained when changing between screens, if set to zero.
• Improved the AI for ship formation movement, to keep ships moving at speed more often.
• Convoys now retain any surplus supplies when unloading into a port that can’t hold their entire cargo, instead of ditching them.
• Supply convoys now try to steer clear of enemy ports.


UI:

• Updated Chinese language text.
• Fleet alert dates are localised.
• Aircraft flights in the squadron list show the planes' campaign-level order, if they have no combat-level order.
• Added a toggle for v-sync.
• Added a warning icon when torpedoes are near a player’s ship.
• The upgrade button is available for Japanese home ports that are not major ports but have shipyards.

Bug fixes:

• Ensured landed planes do not attempt to follow their squadron leader until they are actually airborne.
• Fixed kamikaze aircraft being reluctant to attack when ordered to.
• Critically hit damage sections repair correctly.
• Ships lose their “crippled” status effect when sufficiently repaired in port. (Cause of a ship being unable to turn as the rudder was frozen).
• Landed aircraft flights do not display in the squadron list.
• AI fleets obey their own faction’s amphibious assault cool down time.
• Fixed a bug where battles encompassing multiple ports would not end correctly.
• Fixed the Pearl Harbor log duplicating upon loading a save.
• Stopped controls remaining disabled when cancelling out of naming a save.
• Aircraft cannot start a battle against destroyed ports, and will not try to attack them.
• Removed unused joystick inputs.
• A port’s reconnaissance level is reset upon its capture.
• Fixed the Plane Killer and Against The Odds steam achievements.
• Fixed an instance of hostile ships spawning too close to each other at the start of combat.
• Also, fixed an instance of hostile ships spawning too far from each other at the start of combat.
• Improved torpedo accuracy.
• Fixed ships assigning more crew to some subsystems than their maximum capacity, leaving no crew in others.
• The flight selection panel shows accurate service ceilings in metres.
• Increased the speed of the Grumman Hellcat and the Douglas Devastator, and the range of the Yokosuka “Judy”, to more accurate values.
• Updated navigation to open up some impassable areas of sea in combat view.
• The resource panel shows the correct number of available bombs in a port.
• Fixed a bug where one aircraft flight in a squadron could forget its position.
• Fixed a bug (from the beta patch) where dive-bombers would refuse to dive-bomb.
• Fixed a bug where aircraft payloads could sometimes not be swapped.
• Can no longer order a fleet to merge into one of another navy.
• Fixed a bug where shells, bombs, and torpedoes could teleport away upon moving the camera.
• Fixed a bug where aircraft weapons could load incorrectly from saves.
• The Vought Corsair fighter has a shorter, more accurate range.
• Non-hostile Allied ports in the Japanese campaign do not declare war if the player starts combat with a hostile Allied fleet nearby.
• Stopped erroneously excessive shell amounts being taken from ports when resupplying.
• The atomic bomb collection icon does not show up unless that objective is active.
• Ships no longer ignore the presence of aircraft-launched torpedoes.
• Updated fleet movement mechanic, and fixed some formation and ship spawning issues.
• Fixed the supply convoy list getting confused by multiple convoys of the same name.
