Hearts of Iron IV News

Hello everybody and welcome to another dev diary for the upcoming Barbarossa patch and yet to be announced DLC. Today I’m going to be talking about the first focus tree which is a rework of Poland.

Poland was first added as a free DLC on release for everyone titled "United and Ready" so as such what you see in this diary will be free for everyone once Barbarossa drops. Next diary we will continue on to cover the DLC parts of the focus tree, because the tree is a bit too large to cover in one go. Enjoy!

Poland is interesting because it is a hugely popular minor (it's roughly as popular as Spain and more popular than Greece). Yet it has a very difficult position sandwiched between Soviet and Germany, which tend to scare people off. Perhaps it's the challenge, or its critical role in WW2, or just the large amount of Polish HOI4 fans, you tell me.



So, if we load up the tree we can see not only Ignacy Mościcki’s beautiful new portrait, but an entirely new tree.



Let’s start with the industrial branch. In the old tree, the player would have to dredge through a lot of low-value research bonuses to get just a few extra factories, so many of those old focuses have been expanded with extra factories and bonuses. But, this branch is not just about getting free factories, Poland is on a tight schedule and must use her time well if she has ambitions of outlasting the Reich.



Many industry focuses for Poland grant powerful but temporary bonuses towards consumer goods and construction speed so time the funding of your armement well to maximize the bonuses you’ll get.



Poland was a nation with many problems in 1936, and one such problem was that their rail networks were disparate and disconnected; largely due to the fact that Poland had only a few decades prior been part of three different nations. Among many problems this caused for Poland, it also disrupted their agricultural supply networks, which resulted in the Peasant’s Strike of 1937.



Beginning as mere whispers among the peasantry, if Poland fails to join the supply networks and enact major agricultural reform, they will be faced with a nasty peasant’s strike, damaging their stability, industry, and populace. Though on a tight schedule, Poland may pacify the countryside to delay this uprising, but until reform is enacted, the peasants will remain restless.




Failing to enact reform entirely will result in a massive populist uprising, and a civil war is the last thing Poland needs. If Poland is to survive the Reich and the USSR, she must be united and ready.



Moving on to another issue Poland had in the 30s; we have the Free City of Danzig! Danzig/Gdansk was in a unique and complicated position in this period. The city was simultaneously free and owned by no-one, an official Polish protectorate, and an international city partially run by the League of Nations. So representing Danzig/Gdansk as an on-map tag in 36 felt not quite right, so instead the city is demilitarized and Poland is incapable of accessing any of their factories, resources, or manpower.



When the Nazi party took power in the city, it strangled Polish trade, so Poland begins the game with the “Embargoed Economy” trade law, similar to Undisturbed Isolation in the US but not nearly as harsh. To remove the Embargoed Economy, Poland must either develop a new trade port in Gdynia, gain a new port through conquest, or clamp down on Danzig.



Attempting to seize control of Danzig will cause the city to begin a resistance, and Poland can fight that resistance through decisions and the usual resistance/compliance mechanics. With enough compliance, Poland will be able to ban the Nazi party and take permanent control of the city; ending the resistance, gaining access to all of Danzig’s resources, manpower, and industry, and finally being able to remove the embargoed economy.



Failing to bring Danzig under control will result in the city rising up against you and appearing as a tag on the map. Failing to stamp out this uprising in time will cause the city to defect to the Reich.



Failing to bring Danzig under control will result in the city rising up against you and appearing as a tag on the map. Failing to stamp out this uprising in time will cause the city to defect to the Reich.



Historically, Poland believed the USSR to be the greater threat and didn’t begin preparing Plan West until just two years before invasion. But, with the power of hindsight, the player can start either plan immediately after completing the Prepare for the Next War focus, and accumulate forts and construction bonuses along the border.



However, until Plan West has been completed, Plan East cannot be begun and vice versa, but when complete, no further focuses from the branch may be taken.



Finally, probably the part of the tree that has received the most love; the historical Polish political focus branch. Poland was not the united stable regime we had previously seen on release. Along with impending threats outside their borders, Poland was (like most dictatorships) plagued with infighting and factionalism.



The dictatorship was divided between the Castle lead by Ignacy Mościcki, the Sanation Right lead by Edward Rydz-Śmigły, and the Sanation Left led by Walery Sławek.



Each branch of the Sanation has a series of focuses that can be completed for various bonuses and the player does not have to commit to one faction or the other right away. Rather, you can form your government with a multitude of policies from each of the three factions, but the longer you spend forming your government, the less time you have for other things like industry and plans East and West.



Historical Poland will also have access to the April Constitution, the binding document of the Dictatorship. Though it begins weak, through collaboration with Sanations Left and Right, the Constitution will become a powerful bonus to Poland's politics. With all power consolidated in the President, you'll be able to change your laws and your cabinet with ease.



Time isn’t your only opponent here though, each of the two factions will expect Mościcki to appease them by enacting their policies and giving them power. Every focus of the Left you complete will make the Right more irritated and vice versa. On top of that, both factions will passively gain irritation over time so spend too long without taking a side and you risk losing both to civil wars.



Historically, Mościcki maintained control of the government until wartime, at which point it was agreed Śmigły would take control, but Poland failed to last long enough for this to take effect. However, if the player has appointed either Śmigły or Sławek as Chairman of Poland, the Sanation Right/Left can supercede the Castle and become the majority controller of the government. This enables some light alt-history within the historical branch, as well as unlocking new diplomatic options for Poland.



Available to all three factions of the dictatorship is the Align With the West branch, which allows Poland to join the Allies as they were able to in their old tree.



In the 30s, Lithuania was technically at war with Poland until the 1938 Polish ultimatum to Lithuania in which Poland demanded an end to the cold war over Vilnius. As well as being able to gain cooperation and eventually an alliance with Lithuania, Poland may also demand Lithuania’s annexation which can result in occupying Lithuania without the need for war, but take this focus with caution as it extends your frontline with the Axis.



Also, the Romanian Bridgehead Strategy has now been moved to the diplomatic branch and allows Poland to bring Romania into the allies. Historically, Poland and Lithuania had an alliance prior to the war, and Poland can pursue this alliance closer, bringing Romanian guns to the Polish front.



The Sanation Right exclusively has access to Polish Revanchism which has now been expanded into its own full branch. As well as being able to demand the annexation of Lithuania, the Right can pursue both a restored Commonwealth and fulfil the ambition of the Polish–Czechoslovak confederation.



Lastly, the Sanation Left has access to an expanded Baltic Alliance path, allowing them to gain alliances with the Baltic states, Czechoslovakia, and Romania, and unlocking the newly expanded Between the Seas branch!

(It's worth mentioning at this point that most focus icons are placeholder)

No matter which path Poland is pursuing, as long as Poland is not in a faction already, they will be able to realize the Intermarium ambition and create an alliance from sea-to-sea! All they need to do is be considered a major or be a faction leader already, and have a large army. At this point, Poland can be considered a real contender for a major alliance of their own.



The old Between Seas focus was not really “between seas” so much as it was just a Baltic alliance, but now the first nation to be invited to the faction is Romania. After Romania has made their decision, the alliance can spread any direction; north into Scandinavia and the Baltics, and south into the Balkans. Though unlikely, an Italian alliance is not out of the question for Poland here, but some significant change in policy for either nation would be necessary to tempt the Italians away from the Axis.

(Reposted from yesterday due to an error)

Hi everyone and welcome back to regular weekly dev diaries (if you don't count the april fools one last week). I know you are all super excited to hear what we have been up to since Battle for the Bosporus. The answers to that are going to take a few dev diaries to cover, so I figured I would start with a timeline for you:

• We recently released 1.10.4 to fix various multiplayer exploits going on, but seems an important case was not detected at the time so we are working on a 1.10.5 to address that soon.
  
• Pdxcon is coming up in May so expect to hear some more details there.
  
• The yearly anniversary is coming in June so expect some cool stuff and a patch.
  
• We are however spending most of our time on the 1.11 Barbarossa update as well as the unannounced expansion that will be released together with it. That's what we will spend most of our diaries on, as well as today!
  

‘Barbarossa’ and the unannounced DLC will focus on the Eastern Front and the core of Hearts of Iron, which is warfare - particularly land warfare. Historically the Eastern Front was without doubt the most important front for World War II. It was the largest confrontation in history and
is where Hitler’s expansion was first stopped and pushed back signaling the eventual doom of the axis powers. There are several areas we want to improve here. Weather does not feel impactful enough, while historically it had a massive impact. Logistics currently doesn’t have much player interaction and is mostly something you have to deal with only when problems appear, and finally the combat and division meta has been stable (with an emphasis on large divisions) for a long time - something we hope we can shake up. As you can imagine, these are all things that affect the game on a deeper level and take a lot of work to get right.

Today, I’ll give you guys a bit of an overview on the supply aspect, but fair warning: it’s early days and stuff may still change here before we’re done. I’ll probably spend 3+ diaries on supply over the course of the development to cover everything, but I figured it would be nice to hear about the overarching ideas.

The old system worked by having discrete supply areas pathing back to the players capital and keeping track of the bottlenecks. To simplify a bit ;) - those bottlenecks then decided how many units could fit into areas near the front without penalties. The areas themselves were unintuitive to players and required you to check multiple mapmodes to see if you stepped over an edge etc. I do like bottleneck systems though, because feedback is usually immediate, but it suffered from not having much scaling cost as distances increased, so it was hard to use it to limit snowballing. As I mentioned it was also a system you didn't care too much about until you had problems, while historically, logistics was a vital part of planning a campaign. This led to combining the issue with another gripe of ours - that the way fronts moved in WW2 often followed important railroads, but don't really in HOI4. We came to the conclusion that we should try and make a system focused on railways and with a truck based component as a way to get more out of it when away from the rails.



In our new system, supply flows from the capital (the total amount available depends on your total industrial base) through railways, where the level of the railway acts as a bottleneck. To transport more, you need a higher level railway (or a bigger port if it goes over water) so the railways are the current bottlenecks in a way. Depending on how much supply is transported you need a certain amount of trains for the rails to perform. Trains are a new equipment type that we will dig into in a future diary (well actually, several types ;P)

An important part of railways is that they are capturable, so as you push into enemy territory you will want to make sure to hold vital railways and capture railway hubs to supply your troops. There is a conversion time here to model the fact that there was usually some repair or re-gauging that needed to happen for attackers.

Mapmodes are still quite WIP ;)

Rivers also had a huge importance on the eastern front for transport and supply so they will work essentially like basic railroads now, where you need to control both sides of their banks to use them to ship supplies around.



Supply is drawn from what we call Supply Hubs now, which are either cities, naval bases, or manually constructed stations along the rails, which have to be linked into the network. Air supply works a bit differently but we will talk about this in the future along with some other supply additions...

The flow of supply from a Hub to a division depends on the terrain/weather etc, and ideally you want to have available trucks here (which is to say, motorized equipment) to increase the amount of supply you get as well as range. Cost of trucks and trains and losses to attrition and bad weather will be a limiting factor on your logistics.



Overall, this creates a system where it's strategically sound to fight over railways, prepare for large offensives, to try and bleed each other's logistics capability and to force care when advancing in bad terrain and weather. The result is a much more fun, historical and immersive Eastern Front as well as adding a new layer of invasion planning in the rest of the world.

See you all next week for the next diary!

You can find the forum post here: https://pdxint.at/3dQGUZk

Hello everyone!

So this is a first for me, my brand own dev diary! Well... in fact, I am in a bit of an odd situation. I fell asleep one day in the office about a year ago and no one came in the next morning. The building was put in lockdown during COVID so I haven’t been able to get out and I cannot contact anyone from the team.

I am running low on cash and the only way I can afford to eat is by having uber eats delivered takeout via drones, so I need you to buy this otherwise I have to resort to hunting spiders in the office.

First of a bit of a backstory since this might come as a surprise for some of you, it sure did for me. At first I thought it was a data anomaly but I have to finally admit...that it's not.

Ever since Malta was introduced as a playable nation in MtG we have seen a steady increase in players who are real hardcore about playing the island state. In fact most of you reading this are, 84% in fact.



Why are you all so crazy about Malta? I have no idea and I am no data guy but to me this signal is pretty clear and I can no longer ignore it. As such I have decided to completely shift gear from our 5 year plan to a huge Malta focus tree. You heard it right here folks, I am finally delivering what you want and no longer will you be bound by your shackles of torment!

Obviously I cannot detail everything in one single dev diary. I need to hurry up to check out my spider traps for food, but there are some new unique features that are implemented specifically for Malta, so broad strokes will be covered in this diary, with more in depth path walkthroughs next time!

[h2]
Economy 2.0[/h2]

Malta now begins as a proper colony of the UK ingame instead of being annexed by them. While the domestic industry will be limited by physical size the country can establish shipping lanes between other countries which trades sandstone. This was a brilliant invention of mine where I realized that Malta was pretty much completely void of industry and needed something that everyone wanted!



Everyone? Yup, to make sure Malta gets the proper starting economy every construction and building you make now will require sandstone, which you have a monopoly on. It will therefore be very important to establish close ties with Malta, or your industry will hit a (sand) stone wall.

As more shipping lanes are established and countries buy more of your sandstone you get IC output in return. More sandstone can be mined via events, focuses, decisions and by scuttling your own houses to mine their stone, at the cost of taking a stability hit.

Beware though, if you push your trade routes to everyone at once too fast you risk getting the worst malus of all, tourists. They will arrive in great hordes and block your island, making deploying divisions impossible, and slowly erode all your precious sandstone as they walk around to take in the island’s sights.



With the power of blockchain technology and adaptive AI I have tied the amount of tourists arriving to real world tourism data, so you better get all achievements before summer!


As you know, Malta has limited land resources and while land reclamation is possible it is quite expensive to do so. Luckily we have the solution - instead of building horizontally we are building vertically!

Malta will be able to build several different levels of its country, like a skyscraper. Every level has a set amount of construction slots allotted to them and the player can construct buildings in these slots using the IC gained from the precious sandstone trade. Every new level also requires more and more sandstone, so the player will need to balance foreign trade and plopping another piece of tower onto the Maltese masterpiece.

Every level also has a special set of focuses, and I am very proud to let you know that every level up until level 3000 has a unique set of focuses. After that, every level has a randomly generated set of focuses up until int.max (2,147,483,647). If anyone ever reaches that level I know that you are cheating and the game will therefore erase your system32 folder.

As you build more and more levels the lower levels become impossible to bomb by the enemy, as it is protected by the level above it, like a roof.




Of course it gradually becomes harder and harder to build vertically, so every new set of focuses completed will take more and more sandstone.
I hope that this will please all of you that like to hunt achievements, eventually you will be able to literally have enough levels to reach the moon! (yes I did the math on how many levels you would need to reach it)



Some of you will gain quite a wealth via the sandstone trade. If you reach a certain threshold before the fall of France you will be given the opportunity to straight out buy the French fleet instead of it being sunk and scuttled.

This unlocks the first alt-history branch, as you are now a minor powerhouse and with your newly gained armada you will get the choice to transcend into what every HoI player has ever wanted - a pirate state!

A pirate state is a new type of country in which you will transcend beyond the confinement of merely existing as a country with borders and cities, you are now a ruler of the high seas.

Your fleet now serves as your main hubs of recruiting, building and handling politics. Even if the enemy should capture Malta itself you will not capitulate. Instead your capitulation is tied to the brethren court.



Your admirals are now part of this brethren court, with each admiral of your navy serving as a military leader. If all ships in their task force get completely destroyed, you lose the game and capitulate. You can no longer change the admirals of your navy, and naval composition is done automatically depending on the whims of the court itself and the traits of the brethren (A brethren with a submarine fanatic trait will only use submarines for example).

Here you can see your specific brethrens traits, how much loyalty they have towards you, how much loot they have and you can even build some industry that travels with your ships. You can also transport divisions in these task forces which act as raiders if they are close to land.

While you can no longer edit your fleets, every year the brethren court meets in a secret location. If one court member fails to attend in time he or she can be ousted by another one of your admirals, which can lead to wide scale mutinies.

Here you can use saved loot to bribe other leaders of your court to reshuffle ships, oust brethrens or create new task forces if need be.

As corsairs you capture ships instead of destroying them in combat. When you would normally enter a “naval battle” you now enter a “boarding battle” where your crew tries to capture the enemy ships. If you have diver divisions you can also try and capture submarines.

If a crew's loyalty drops below a certain threshold they will rebel and take a part of the fleet away and form their own pirate coven .This uses a very complex algorithm designed by me which follows
no loot -> :( = mutiny

So hi everyone, this diary is something that actually alerted us to CraniumMuppet being locked into the office. When we found him he was passed out under a desk where he seemed to have created some kind of weird court with the local wildlife. He seems a bit confused and groggy but should make a full recovery.

[h3]So anyways, look forward to next week when we will start dev diaries for 1.11 Barbarossa and the next unannounced DLC. See you all then![/h3]
