About This Content

In summer 1937, renewed tensions between Japan and China escalate into open war: The Second Sino-Japanese war has begun.

Order of Battle: WWII comes back to the Pacific Theatre, covering one of the cruellest but most underrated conflicts of the Second World War period.

In Order of Battle: Morning Sun you take control over the Japanese forces fighting for territorial expansion and rich Chinese resources. The conflict soon turns into a massive all-out war between the two sides during the Battle of Shanghai. While the Chinese forces are numerically superior, they have suffered from internal conflict and are poorly equipped with outdated weapons. The recently modernised Japanese Army on the other hand is well trained and experienced, but as the war drags on it gets increasingly overstretched, allowing the enemy to regain the initiative at several occasions...

New units

Japanese armies have been reinforced with several new units including biplane fighters and bombers such as the Ki-10, D1A and A4N1, the Sōkō Sagyō Ki flamethrower-equipped engineering vehicle and Type 89 medium tanks. The Chinese rely heavily on foreign arms deals, resulting in a diverse arsenal made up from Soviet Polikarpov fighters, Tupolev bombers and T-26 tanks, German Panzer I's, Sdkfz 221/222 armoured cars and 37mm PaK guns, Italian L3/33 tankettes, British Gloster Gladiators and many more. Nations now also have access to Cavalry units and Horse Transportation for towed guns. In total, almost 100 new unit types have been added to the game.

This expansion is a fantastic look into an "unexplored" war as well as the vehicles used in that war that is a great extension of the original game. Slitherine should be applauded and rewarded (buy it!) for touching a conflict so important to Japan's involvement in WW2 when others have not.

The pros:

1. Many new units to play and play against including early tankettes, artillery, and early Japanese warplanes most Westerners familiar with the Pacific War may not have seen before. The Chinese have an interesting array of imported vehicles and guns as well.

2. Great maps that emphasize the challenge placed upon Imperial Japan's war ambitions, and how overextending your lines can lead to loss of supply and being surrounded by the superior numbers of the Chinese troops. The maps almost encourage you to overextend, not to mention you have a limited time to complete your missions (though I completed the first one well within the allotted time).

3. Music is much better/ suitable given the subject matter, and there are a few mechanics that may have changed since the patches, such as move / repair which I don't recall - but I could be confusing with Panzerkorps.

4. The campaign selection map is improved over games like Panzerkorps -- it's an actual map and it looks good.

5. The portraits are great and look like old photos of the period - the uniforms of the officers in the portraits are accurate.


1. Can't play China in the campaign --- yet.

2, Graphics or the engine itself seem to choke on occasion even on my relatively powerful system, and can get herky jerky at times.

3. Just a nitpick, but there are a few other early war weapons I have not seen yet in the game (although I have not played all maps yet and have some to go) -- such as the Type 92 Ni-Ku primemover (or other primemovers) that could be an upgrade from horses and trucks and allow towing artillery across rougher terrain, the Type 92 Heavy Armored Vehicle, and the Ki-1 and Ki-2 bombers. Armored trains would also be cool.

Notes: SNLF dark blue uniforms (with white straps crossing chest - light colored helmets?) would be nice to see and a contrast to so many khaki colored uniforms on both sides. May pop up later in the game? Here is an example with a soldier in front of a Type 93 Naval Armored Car ("Osaka" in the game)

ON THE NEGATIVE REVIEWS: I fully support being able to play China, but think it is not fair to judge the game on this missing aspect (though it should be clear before you buy the DLC). I have a feeling Slitherine will move to add a China campaign. To say this game is bad because it only plays from the Japanese side is like arguing that a game about Napoleon's conquests is unfair to every nation he invaded that you are unable to play. There are many games out there that "promote war and aggression" if you think about it - just this particular war between Japan and China raises particular emotions - AND by being a trailblazer here (few wargames touch on these scenarios / locations), Slitherine was bound to raise some hackles with this release, even if China had been playable. If you think about it, any country invaded in numerous games about Germany cannot fight back -- but these wars even from Germany's perspective are covered by serious wargame companies who want to cover all types of battles for a rabid fanbase that cares. This is the nature of WAR-GAMING - not to get someone all emotionally wound up (does anyone still get emotional over Napoleon's or Rome's conquests?), but to enjoy the simple strategies of war for what they were ... and all aspects should be explored.

The War was 70 years or more ago. It is not "too soon". Let us explore these battles from all sides. China, the Commonwealth (Chindits), ANZAC, India, -- yes even Imperial Japan -- whatever Slitherine can provide.

Fun as hell to play as the empire of japan unleashing its conquests on china, people are complaining because the dlc does not have china as a playable campaign nation but historicaly it wouldve just been playing a game full of defeats there was no way china wouldve been able to do anything to stop japan.

Wow, what a fun campaign. Genocidal history aside... I super enjoyed this, it was fun and challenging. You felt super overextended almost all the time by halfway through the campaign. The end was also very satisfying if you achieve total victory.

China is a refreshing, seldom-used setting, and it fits the game well. The campaign was for me more immersive than the two original ones and the scenarios are well-crafted. Sometimes it felt like I was in the "Empire of the Sun" movie! All of the new units and assets look great.

Personally, my best Order of Battle experience!

Playing as the Japanese makes you fighting and bringing honorary for the Emperor Hirohito against Chinese Republic
