Re: Mod: MEGA Pacific - Most Realistic Yet - v4.0
Posted: Thu Apr 02, 2026 3:50 am
Man has this update been a long time coming. I promoted positions at work, so I am not able to work on this like I used to, but that doesn't mean I have neglected it. This update is massive enough I feel I can justify a jump to v4.0! New unique units, country characteristic refinements, map improvements, new script decisions...all kinds of goodies in this one. All backed up with historical research! All sorts of improvements to make this mod the MOST REALISTIC YET!
Change log v4.0:
House Rule Changes:
-REALISM: The only Allied aircraft that can be in China must come from AMMtC or GB. No other outside aircraft allowed.
-Japanese Light Cruisers can only have a maximum of two total points worth of upgrades.
Bugs:
-Fixed error not allowing Japanese minors to be upgraded.
-Fixed several typos in popups.
-Fixed Diplomacy chits for countries.
-DEI now declares war on Japan on the Allies first turn
Scripts:
-(Great Britain, New) Build new ports in the Bay of Bengal
-(Japan, New) decision event asking whether Japan wants to develop a new AA "San Shiki-dan / Type 3 shell" that could have dire consequences.
-(Japan, New) Decision event asking if you want to rebuild or scrap Fortress Singapore.
-(Japan) Free Indian Army formation pushed back to historical date of October 1943.
-(Japan) Shinano and NO.111 DE scripts changed to include some technology on their arrival.
-(USA) The option for the Doolittle Raid will not appear until Jan 25, 1942.
-(China) The first corruption hit is now 2-4 health points off all infantry. Elite Corps around Communist China given extra HP to balance.
-(Thailand) Receives Division by production date, no longer script.
-(Communist China) DE200 "Strengthen the Bases" now fires when CC is 65% mobilized instead of a preset date. This allows the player to evaluate more of the Japanese player's intentions.
-(Communist China) Lowered starting mobilization %, lowered Japanese near a base to 5-15%.
-Solomons and New Guinea Territory each are their own convoy to Japan.
-Added a backup convoy from Melbourne to India in case Perth is closed down.
-One unit in Johore will block land supply to Singapore.
-With Singapore in Japanese hands, the British LNG will lose 3 strength per turn.
Map:
-Moved the Capital of British Raj from Delhi to Bombay. Yes this is not historical, but I think it is necessary for balance. Delhi is just too far away to invade.
-Moved Chinese second capitol from Lanzhou to Xi'an.
-Reformed the mouth of the Yangtze river for a more natural and consistent look.
-Nanjing renamed Reorganized National Government of China. Units re-evaluated.
-(Solomons) Expanded Rabaul now a town and a fortress. Redesigned New Ireland islands.
-Tibet changed to true Neutral and road added to Lanzhou.
-Rail line between Chungking and Chengdu deleted (none existed until 1952).
-Geographic changes around Davao, Aparri, and Guadalcanal.
-Remapped the roads and rails of western Australia to historical standards.

-Hainan island (occupied China) redone. It lost a port and downgraded to secondary supply status. Japan got a regiment added to the island.
-Added more mountains around Communist China.
-Moved Japanese regiment from Kwajalein to Tarawa.
-Changed to small river around Singapore.
All Unit Changes:
-Infantry unit levels redesigned. Battalion is removed and sizes adapted. Now Regiment/Division/Small Corp/Corp. Small Corp is not available to most nations.
-Naval cruise increased from 1.75X to 2X. Some minor adjustments to ship AP.
-Special Forces and Paratroopers lowered to 8 health since they represent a smaller amount of troops.
-Paratroopers operational starting range lowered to 5, twin engine tech increases range by 2. They also now get a +2 range bonus when operating from an airfield.
-Minor +/- AA defense changes to Prewar/Fast/Super Battleships.
-Heavy Cruiser -1 defense against Strategic Bomber.
-Heavy Cruiser is downgraded to weak zone of control. Other land units raised or lowered based on use.

-Auxiliary Ship cost, stats, start dates, and production changed.
-Coastal Defense Battery naval attack evasion lowered to 20% (-20).
-Militia Infantry Weapons soft attack increased to 1 (+0.5) per level.
-Light Cruiser visibility stats reworked. Allies: Aircraft upgrades +1 naval sighting and lowered upgrade cost for Single Engine Aircraft. Japan: 1 land / 2 Sea per level.
-Strategic Bombers changed a up a bit. US/GB are matching and Ground Attack weapons now represent incendiary bombs (extra resource damage). Japan's Strat Bomber only gets one upgrade, but it adds quite a punch and distance.
Tech:
-Many adjustments to tech chits, costs, and % levels across all countries.
-Renamed Naval Construction to Port Construction.
-Renamed Production to Efficiency and Capacity
-Renamed Industry and Manpower to Conscription and Labor Laws
-Search Radar on carriers now gives +2 sea visibility.
-Supply Depot adds a second strike and +1AP to armored units.
-Japan loses starting chit in Search Radar, but gains a level in Advanced Tanks.
-Japan moved to Amphibious level 2.
-Submarine Warfare: Rewrote description. Japan only: +2 build limit for Aux Ship, lowered raiding increases.
-GB: loses a starting chit in Production Efficiency
-USA: Production Efficiency chit lowered to max of 2 chits, max level 3. Increased discount to 10% per level.
-USA: Production Efficiency Tech is now 10% discount per level.
-USA: +1 level of Advanced Tanks.
-Logistics increases aircraft build limits for AMMtC by 0.5 per level.
Country Specific Unit Changes:
-(China) Fortified position has lower antiair defense.
-(China/Japan) Rearranged some central units.
-(China) Altered some units in the Deployment and Production que. Added XP and max health to the Corps outside CC so they will still be effective after the corruption hit.
-(Philippines) Added battalion unit in Mindanao and Aparri.
-(Japan) Malaya and Philippine invasion fleets partially redesigned based on the new unit structure.
-(Japan) No concern for commerce: Japan's navy has drastically reduced commerce raiding abilities. It can marginally be improved by Submarine Warfare.
-(Japan) Long Lance benefit changed: base 15% evasion and Destroyers +1 Naval/Carrier attack. Only +5% per level.
-(Japan) Reevaluated submarines and technology based on historical standards, including adding to production que and production delay.
-(Japan) Made several changes to their tank units.
-(Japan) Paratrooper moved to mainland and lowered to half strength to represent training.
-(Japan) Light Cruiser moved from Kurile to Bonin fleet and given torpedo upgrade.
-(Japan) Two Auxiliary Ships placed in production que.
-(Japan) CV Taiho altered to have 13 Hull strength, but arrives with no aircraft (it was heavily armored).
-(Japan) CVL Hosho lowered to 3hp/5air status to reflect poor condition.
-(Japan) Three "Air Training" aircraft units' stats changed to improve their retained air experience. These represent the last highly trained pilots produced by Japan.
-(Australia) Loses the destroyer, but gains three Auxiliary Ships in Singapore, Darwin, and Sydney.
-(Australia) Build limits of ships adjusted downwards. They only built destroyers and smaller.
-(Thailand) Army/Navy/Airforce redesigned to match historical levels.
-(GB) Armored Fleet carriers: defense increased in Kamikaze, Bomber, and Carrier to 3, and 1 in Naval defense. Max health set at 8 because they traded armor for few aircraft.
-(GB) Gained a medium bomber in Malaya.
-(GB) Removed ground units sitting in Britain.
-(British Raj) Lost the medium bomber but gained a fighter.
-(British Raj) Starting ground units altered and switched locations to be more historical.
-(British Raj) Build limits changed according to country's 1941+ industry capacity. With tech development, the industrial limits can expand.
-(USA) 3 additional Essex class carriers added to production que.
-(USA) Lowered some tech levels of Asiatic submarine fleet.
-(USA) Philippine starting aircraft numbers and tech adjusted.
-(Nepal) Units changed.
-(AMMtC) Build limits changed to focus on aircraft and small infantry units.
-(RNGoC) Military build limits adjusted based on historic levels.
-(Malaya) Switched out British Raj fighter for Great Britain fighter.
Country Characteristics Changes:
-(Tibet) completely redone. Now a true neutral with diplomacy cheaper and more effective through British Raj and China.
-(China) Poorly trained troops: -1 attack vs soft/hard/aircraft/naval.
-(China) AA upgrades are more expensive than others (+5%, equipment hard to import)
-(China) Rushed conscription: Cheaper and quicker to build Division and Corp.
-(Communist China) Dedication ideology. Units are reformable at 3 supply, cheaper and faster to reform.
-(Japan) Banzai! Fight to the last man. Cannot reform Battalion and Regiment units if destroyed.
-(Japan) Cruiser scouting doctrine. Fleet Carriers have only 3 (-2) sea visibility.
-(Japan) Antiquated but customizable Light Cruisers: The basic light cruiser is fairly weak, however, they can be specialized into ASW, Torpedo Cruiser, or highly effective recon. AA is only upgraded with ASW upgrade.
-(Japan) Long Lance is now +1 naval attack to destroyers and all torpedo ships have base 15% evasion. Torpedo upgrade will now only be 5% increase in evasion (same as Allies).
-(Japan) Readjusted Auxiliary Ship. Aux ships will mostly represent obsolete destroyers at the beginning of the game, and KaibÅkan ("Ocean Defense Ships") in the latter part. By 1944, Type C & D were built quick and simple for escort duties, outpacing even the USA in build time. They build quickly, but are less robust and move slower. Historically, C & D were equipped with only 2-3 guns, depth charges, and minimal AA.
-(Allies) Readjusted Auxiliary Ship. Represents a wide range of ships with flexibility in the design, cheap upgrades, but starts with only basic guns and AA. Could represent MTBs, destroyer escorts, or an ice cream ship (look it up). Better defense, AA, and +2AP compared to Japan. Cheaper to build than destroyers.
-(Australia) Readjusted Auxiliary Ship. Australia built "minesweepers" but were actually more of a multipurpose corvette. These ships provided crucial escort duties throughout the war, but were lightly armed. +1 Sub attack, -1 Naval Defense compared to default Allied.
-(British Raj) India provided millions of soldiers to the Allies but only had light manufacturing. It mostly produced small arms but could manufacture small aircraft too. Soldiers are cheap and plentiful, but advanced manufacturing has to be developed with Efficiency & Capacity Technology before India can build more complex units.
-(USA) Essex class fleet carriers arrive with increased HP, aircraft, and experience.
-(USA) Germany comes first: Most infantry units were sent to Europe. Limited ground units are available, but this number can be increased by research. Increase the effectiveness of your infantry units by island hopping combined with superior air and naval tactics.
