Hearts of Iron IV - PDX Katten

Hey everyone! You probably don’t know me, but I’m Carlo, the Content Designer in charge of Switzerland for BBA. I’m very excited to present to you all, the Swiss Focus Tree, our first circular focus tree, allowing Switzerland to go back and forth between the Make Fondue and Stay Neutral focuses. Through the power of Fondue and Chill, plus all that Nazi gold, Switzerland will prevail over its rivals by completely staying out of the war in absolute comfort and safety.​


[Record Scratch Sound] If that’s how you imagine Swiss life during World War II, I got news for you buddy, that is far from how it went.

Yes, Switzerland is not a country most people associate with World War II games, but that doesn’t mean it doesn’t have a place in HoI, and in this Dev Diary I hope to bring you to my side of the Alps and show you how interesting and unique Switzerland can be in Hearts of Iron IV.

First, it’s always a good idea to have a bit of historical context. Switzerland was founded in the late Middle Ages and from the start, it was a loose confederation of small territories near the alps (3 at this point). They pledged to help each other militarily and economically. This oath, or Eidgenossenschaft as it’s lovingly abbreviated, kept growing while always maintaining a decentralized government centered on the cantons, and with a strong military reputation (Despite their current neutrality). Then Napoleon forced Switzerland into a centralized ‘Helvetic Republic’, which didn’t last long. Swiss Neutrality was established after the fall of Napoleon and of this Helvetic Republic, and then finally, in 1848 they became the Switzerland we know and love after adopting the 1848 Constitution following a short revolution (Revolutions were all the rage that year).

So what’s the Switzerland we know and love? A country with 4 different populations living as one in a period of rising ethno-nationalism. The oldest continuous democracy in Europe, second in the world only to the United States, and arguably, the most direct democracy in our times, and even more so in the 1930s. Each canton and the confederation itself decide most of their laws through referendums and a limited representative body. If you’ve ever wondered why the Country Leader of Switzerland is a building, that’s not because it gained sentience, but because there is no Swiss President/Dictator/Regent as other countries have; The Swiss confederation is led by the bi-cameral Federal Assembly and a Federal Council of 7, with a mostly ceremonial ‘First among equals’ Presidential role; only the whole Federal Council can act as the Head of State, not a single member.

Switzerland in 1936 is a country gripped by the fear of war breaking out. Thanks to Germany going through Belgium during The Great War, they know that their status as a neutral country is not sacred, and when their two biggest neighbors, the Third Reich and France inevitably clash, there’s a real possibility one of them will stomp through Switzerland to avoid the other's defenses. How to avoid this, while keeping Swiss Democracy alive, and being ready in case it actually happens are the main pillars of playing Historical Switzerland in Hearts of Iron IV.

So what does the Swiss Focus Tree look like? Well like this:​


Because this one’s more of a focus mountain than a focus tree, you always start at the peak, with the center being the historical path, and the sides the two planned alt-history branches, but it always starts with the Swiss Guiding Principles focus. This will initiate the Balance of Power system for Switzerland and trigger an event where you can choose the general direction Switzerland will take. Let’s stop to talk a bit about the Swiss version of the Balance of power:

If you don’t know what the Balance of power is, make sure to read Mano de Zombi’s amazing and gargantuan Dev Diary.​


Switzerland’s path through the Hearts of Iron period will depend heavily on where the power lays. Is the power mostly on the cantons? That means it will go the way it went historically, with local citizen militias and limited council power, which made it hard for the country to ally with a foreign power, but at the same time, prevented a central government from being intimidated into capitulation. If instead, the Balance of Power is in the council, you’ll be locked out of part of the Historical Path in the middle, but when the BoP closes a door, it opens a window into the two alt-history paths. That’s a topic for my next dev diary though.​


Each side and segment has its advantages too, the more cantonal power, the cheaper assigning advisors will be, and moving it to the council will grant you War Support. Some of the decisions in the other systems will depend on it, and others will affect it, so keeping an eye on it will be vital to your survival.

Now let’s keep going down the slope. These two focuses will kickstart the rearmament of Switzerland, giving you a National Spirit that will be helpful for you no matter which path you choose and can be upgraded later.​



Switzerland had committed to defending their country both physically and spiritually in 1935; we saw the beginning on the physical part with the rearmament focuses, and now it’s time to recommit to the spiritual bit. This will unlock the Spirit of Helvetia National Spirit, in its passive mode.​



As you progress through the Historical path, it will change to a defensive stance, an aggressive stance if you go alt-history or it might just stay in the passive stance. Each one also has an “at war” variation, and different modifiers for the six of them.
This is fine…


In case you’re wondering who this Helvetia person is, I must take you back to the Helvetic History Hole(tm): Back in Roman Empire times, a tribe called the Helvetii lived in what we now know as the Swiss Plateau, so people since have used the adjective “helvetic” to define confederations, republics and organizations in and around this area, specially after Napoleon created the “Helvetic Republic''. Due to the multilingual nature of Switzerland, its official name in Latin is Confoederatio Helvetica (Yes, that’s where the font name comes from) and its internet domain is “.CH”. From this root, in the 17th century Helvetia is popularized, the personification of Switzerland and the Swiss people, featured in coins, statues, stamps and World War II Grand Strategy games. That’s who Helvetia is.

Ok, so far, I haven’t given you much of a chance to deviate from history, and that’s because up to this point, this is a nation very committed to Democracy, Neutrality and Grassroots Defense, and even the alt-history paths will stem from the desire to keep these. Here is where the slope starts to open up:​


Historically, Switzerland fortified their borders with its three biggest neighbors, and the three countries it shares languages with, and with good reason, they all wanted to walk through Switzerland towards their enemy, and thought their shared language would serve as an excuse to annex it, or a possible door to friendly relations and taking them from neutrals to allies. Naturally though, fortifying against a country can be seen as suspicious, and that’s why this triggers the start of a very important system: Absolute Neutrality.​


As a small neutral nation, you want to keep a balance between all countries around you so none of them feel like you’re favoring one over the other, otherwise, they could use it as a way to argue that you’ve broken your neutrality, and prompt them to invade. This system keeps track of your biggest neighbors’ opinion of you, and allows you to appease them or antagonize them; most actions will have repercussions to the other countries' perception of you. If one of the countries considers you in grave violation of your neutrality, and has a very negative opinion of you, it’ll trigger a timer, at the end of which they’ll get a wargoal against you and likely invade Switzerland, so you better scramble and do anything in your power to calm them, or it’s game over.​


This system is pretty flexible and can keep track of up to 4 majors around Switzerland, and even adjusts if one or more are in a faction. Also, many focuses will have negative and positive effects on this system, and others will require you to reach a certain opinion of them before starting them, so it’s integrated into how you play as Switzerland.​


After Ban the Swiss Nazi Party (Which does what it says on the tin, plus some negative opinion modifiers), we have the Armed Neutrality branch. This is the central defensive branch of the Swiss tree, and unlocks another system we need to talk about: The Swiss Citizen Militias.


Going back to the Helvetic History Hole now. Because of Switzerland’s political system, there’s no centralized government powerful enough to conscript a large standing army, but on account of where Switzerland is located, it needs to have the ability to defend itself, or at least deter other countries from invading. This is why historically, the Swiss Army relied on training their population and giving them the required equipment to keep at home, so when needed, they would take up arms and form local militias. This means that they could have up to 20% of their population ready to be deployed in as quickly as 24 hours to stand up to any invaders. This is why Historical Switzerland’s military needed its own system.​


Switzerland will start with a unique Recruitment Law giving it 10% recruitable population, and no negative effects, that’s because the enlisted population is still participating in the economy. The downside is that you cannot train regular troops, only some mountaineers, to represent their small professional army, whose purpose was holding out for 24 hours until the civilian militias were ready.​


To make up the bulk of the army, you can train Militias (Italy’s DD also explains this new battalion type). There is a cap to how many divisions you can train, it’s a locked template and on top of that, the Dormant Citizen Militias National Spirit makes them very weak, but that’s ok, you can deal with these issues by earning, and spending Military Readiness.​


You can find this system in the Decisions panel, and it lets you use Political Power, Command Power and other resources to gain Military Readiness, and then you can spend it to improve the Militias Template, increase the amount you can train, expand the Military Readiness cap, even increase your military production; but most importantly deploying your Citizen Militias, which removes Dormant Citizen Militia and adds Active Citizen Militia, allowing them to perform at their true level, but giving your economy some penalties, which grow the longer you keep them active.​


Back to the Focus tree, under Armed Neutrality you’ll find three branches; The Promote Guisan Branch, the Frontier Defense Plan Branch and a shared one in between. The Frontier Defense Plan was Switzerland’s old strategy of fortifying the borders, and not giving any ground to the enemy, so this sub-branch focuses on improving divisions, and fortifying the borders. Historically, this plan was abandoned when Guisan was promoted to General and Commander-In-Chief.​


Another of the many quirks of the Swiss military and political systems, is that their military ranks only go up to Corps Commander, and there can only be a single General (Who also acts as Commander-In-Chief) when the country is at risk of, or at war. Only 4 people have been assigned this role, and the last was our guy Henri Guisan in 1939, who brought the strategy the Promote Henri Guisan sub-branch focuses on. Broadly speaking, the Réduit National approach consisted in letting the enemy advance through the Swiss Plateau and systematically retreat the armed forces to well fortyfied and supplied forts along the alps. Once there, they could maintain their extremely favorable positions and wreak havoc on the enemy, stuck on the exposed Swiss Plateau. The expectation was not necessarily to liberate the rest of the country, but to make it clear taking Switzerland wouldn’t be easy, and thus deterring any invaders. This is why this sub-branch focuses on making it easier for you to hold out in the mountains for as long as possible, and even adds the Gotthard Pass victory point, which becomes the capital once Bern is lost.​

Ok, that’s the Armed Neutrality branch done, now on to the rest!

Switzerland’s neutrality and proximity to the conflict made it a prime stage for espionage, for both the Allies and Axis, so of course, the Swiss government also needed to keep up with it, often collaborating with the Allies, and, sometimes unknowingly, with the Soviet Union through the Lucy Spy ring. On the historical part of this focus tree, you have two ways of getting a free Intelligence Agency:

Federal Police Intelligence establishes the agency of the same name, an extension of the existing Federal Police, and gives you a National Spirit with a bonus to counter intelligence, and opens the door SpAb to further counteract foreign intelligence efforts, and other fun militaristic alt-history stuff I won’t talk about today.​


On the other side we have Buero Ha, which focuses on building spy networks in other countries and opens up a bunch of defensive, cultural and resistance oriented focuses. Ha History Hole: The Swiss government couldn’t risk other countries finding out they were gathering intelligence on them, so to keep it under wraps and have a measure of deniability, they established a covert pseudo-independent intelligence office; Hans Hausamann’s Büro Ha (The “Ha” part comes from his name). It was an office in a hotel in Teufen with a couple of desks, and they gathered and reported on intelligence from different sources, including the Lucy Spy Ring, which deserves its own historical rabbit hole but not today.​


And that, in very broad strokes, is the Swiss Focus Tree, but there’s still some important things to talk about.

I’ve babbled on about Switzerland’s unique political system in real life, but now it’s time to explain how it’s being represented in HoI4: Switzerland will start with 3 assigned political advisors, and these represent the ‘leading’ Federal Councilors (Out of the 7 on the real council), plus a President of the Confederation. Each advisor has one of the new traits unique to Switzerland, most of which correspond to the advisor’s role and/or political position during the period. Each year, starting from 1937, you’ll get an event prompting you to elect a new president from your active advisors, this advisor will be removed, and retired forever, but for the next year you’ll get a powerful decision based on the trait they had when they were advisors. After that you better assign a new advisor quickly, or you’ll suffer the consequences of an empty seat. In total there will be at least 25 Political Advisors to choose from with at least 10 different traits, that I hope will make for an engaging and unique system, and a key to the Alternate paths through its interactions with the Balance of Power. More about that on my next Dev Diary.​


At this point you’ve probably noticed that the map has changed a bit in and around the Alps, let me explain what we’ve done: The most important change is that we reshuffled the states in Switzerland, it now has five states: The Swiss Plateau, Western Swiss Alps, Eastern Swiss Alps, Ticino and Jura Mountains (Fun fact, this is where the term Jurassic comes from), there’s also some new Victory Points. On top of that, Austria did get something after all, Voralberg, a new state I might talk about in the next Dev Diary.​


The other change you might’ve noticed is that a lot of the provinces along the alps now have impassable borders, helping represent how much of an obstacle the alps were in moving troops and attacking (Unless you happen to have elephants), and showcasing one of Switzerland’s bargaining chips during this period: the Saint Gotthard Pass. This route was vital as a fast passage between Germany and Italy, and the possibility of its destruction was a major deterrent against Invasion. HoI4’s Switzerland now has 2 out of the 3 connections through the alps, making it a more tempting prize for anyone playing one of its neighbors; German command even considered invading Switzerland as a way of retreating from Italy in the late stages of the war.


And that’s about it. If these 2800+ words didn’t at least pique your interest in the Swiss Focus tree, well… We do have one extra card up our sleeve:

Switzerland will feature the first dog in a Focus Icon, also featured as a National Spirit: Brandy the St Bernard. The focus Spirit of Saint Bernard will give bonuses for Field Hospitals, slightly ahistorical, but worth it.​


Hope this Dev Diary helped you understand all the ways the real Switzerland was and continues to be fascinating, and how it serves as a great base for unique gameplay for Hearts of Iron IV, or at the very least provided some mild entertainment and a nice dog picture.

And if you won’t have to wait too long for another super interesting country, because next week, it’s Ethiopia time! A country that has always been pivotal to World War II, now gets to have its moment to shine in Hearts of Iron IV.​

Greetings Generals

The long tradition of HoI anniversary surprises, while slightly delayed, has not been forgotten.

Today, we have the pleasure of announcing to you the next milestone in the Hearts of Iron story: By Blood Alone. Over the coming months, we’ll be revealing more on what each of these features consists of, but for now enjoy a snapshot of the future for Hearts of Iron.

In By Blood Alone, you will chart the course of Mussolini’s regime in Italy or subvert Italy’s historical path in one of many new alt-historical paths in the new Italian focus tree, driven by the constant involvement in war from the beginning to the end of the game.

Choose to take on the task of resisting the Italian colonial occupation as Ethiopia in their new, expansive focus tree. Will you go into exile only to return stronger than ever when the greater conflict ignites, or can you beat the ultimate challenge and evict Italian troops from your land before forging a new path for your country in the prosperous Horn of Africa?

Experience the true meaning of ‘building tall’ by balancing your precarious situation as Switzerland, sandwiched between an ever-growing array of totalitarian regimes. Will you succumb to their pressure, or stand as a shining beacon of democratic ideals in the face of greater odds?

Alongside a number of changes to the air warfare system, take advantage of a comprehensive Plane Designer feature, as well as numerous quality of life improvements and new functionality for owners of La Resistance and the intel system. Accompanying the plane designer, we’ll be adding a whopping 67 new 3d plane models including a wide array of new Italian planes as well as going back and adding models to many important planes currently lacking them.

In By Blood Alone, you will be able to make use of a variety of new demands in the overhauled peace conference feature. Demand the demilitarization of states, the dismantling of military industry in defeated foes, civilian factory war reparations, and access to resource rights in addition to the expected array of peace conference actions. Of course, we can’t forget that navies played an important part of post-war negotiations - augment your victory by partitioning the navies of defeated foes, and put these behemoths of the sea to good use as you look towards the next conflict.

Divisional Commanders will now be the bread and butter of your future officer candidates. Grow their skills passively as they perform their duties in command of divisions, reward their actions in combat with country-unique medals, and see their persistent achievements follow them as they are promoted to higher positions over the course of a game.

Encounter up to 20 new unit models and associated SFX, 12 new radio-integrated music tracks, and new diplomatic actions as well as many more quality of life and functional improvements to HoI in By Blood Alone.

As mentioned above, we’ll be delving much deeper into what each of these features will consist of in the coming weeks and months leading up to release. Stay tuned for more information!

Hearts of Iron IV - PDXMidgeman

Hello there, C0RAX here. Welcome aboard to my dev corner, in this thread I'll be going over the core introduction of the planned changes to naval gameplay.

Why? The Live System:
  • Good ship design is unintuitive.
  • Combat revolves around exploiting oversights
  • Ahistorical meta



Goals
  • Clearer design process
  • Meta based upon good structure and multiple key values
  • Making historic choices in naval design and composition work well in game

Rebalance Overview
  • Tech Tree
  • Ship Designer
  • Hit profiles
  • Spotting
  • Fleet composition
Tech tree

The most obvious change is our first port of call today, this is the tech tree. There are a number of changes here that will be explained in further detail further to the aft of the dev corner.



So firstly the naval tech tree has been split into 2, the naval tab contains hulls and tech directly linked to hulls. Let's take a look at what that looks like.




As you can see it's much more concise than before, armor techs have been combined so each level will unlock both heavy and cruiser armours and are not linked to any specific hulls. SH armor still remains part of the super heavy battleship.

Moving on to the new “Naval Support” tab.




Here you will see quite a difference from the old tech tree. Gone are the secondary battery techs as they are now research via the medium gun techs



Additionally the naval shell upgrades are now part of the gun lines acting as an intermediary tech between new modules. But don't worry about having to research more techs, XP reductions are gone but base research times are down.



Dual Purpose Guns

And let's finally address that big elephant in the room… Dual purpose guns now branch off the light gun line. They are a 1939 onward tech, with the UK,USA,Japan & France starting with the Basic dual purpose Battery Researched and historic ships starting equipped with dual purpose Batteries and dual purpose Secondaries. Dual purpose guns lack the piercing of regular guns but make up for it by also providing AA.




The current values for the dual purpose batteries are not final and are currently aligned with their non AA equivalents.



Finally we have the 1944 Advanced medium dual purpose battery which packs a punch both to ships and planes, which should you reach it could wreak havoc for enemy aircraft and destroyers alike.



Hit profiles & damage ("well the front fell off")

Quick primer on hit profile in case you don't know what they are. A Hit profile is the calculation used to determine how easy it is to hit a ship. This hit profile is then divided by the accuracy of the weapon type a ship is firing (10 * (Hitprofile/weaponaccuracy)^2).

Any other effects that affect hit chances such as weather/time of day are applied to the final value. Currently the live game calculation for a hit profile is the ( (visibility * 100) / speed) .

So a ship with a high hit profile will be easier to hit than one with a small hit profile.

A change to the hit profile calculation is aimed to reduce the impact of speed on hit chance and should flatten the effect of speed for much slower ships. The current but not final working formula is:

( (visibility * 100) / ( (speed/2) + 15) )

In addition to this there have been some other changes for hit chance

New hit chance modifiers that affect hit chance in the same way that weather affects hit chance. The new modifiers replace existing stat modifiers for modules/tech.
  • Radar and fire control increase light and heavy guns hit chance
  • homing torpedoes now increase torpedo hit chance
  • Base critical chance is reduced




Spotting
  • Spotting is now min capped at 0.01% progress per hour, so you will always spot a task force after 10,000 hours (417 days)
  • Random chance to instantly spot (encounter) equal to your hourly progress, so if you have a 4% hourly progress you also have a 4% chance to “encounter” a task force.
  • Sub and surface detections for a task force are now listed in the task force information tooltip.



Fleet Composition

First joining an ongoing battle was very painful and making strike forces much less useful this should be much less of an issue with much lower and shorter lived penalties for positioning.



Additionally SUPREMACY_PER_SHIP_BASE has been reduced from 100>75 so that IC and manpower have a greater impact on naval supremacy.

Ship Designer

The ship designer has some of the most major changes to existing ships and modules. Let's go through them by groupings..

Firstly I want to say that you can no longer have both medium cruiser and light cruiser guns on the same design, fitting both will invalidate the design. This will eliminate one of the largest exploits in current ship design and should prevent ships being unintentionally protected by screening.

Now we will get into some gritty details of the current value changes for the rebalance.

(RED=changed values, BLUE=New values and BLACK=unchanged)

Changes to speed,reliability and Production cost.







Changes to speed for hulls




On speed it should be much harder to get 40kt ships now - faster ships hover around ~35kt with slower ships being in the 30kt range. Some older ships and submarines remain well below 30kt and will need upgrading if you want their speed to match modern ships.

Submarine Visibility



Now these are the normal changes to modules and ships, but that's not all we have some new modifiers that are replacing or adding to existing modules too.

Fire control/Radar





Torpedoes



Armor

In addition to the new modifiers below for armor a review of armor values and piercing is planned, but I don’t have a completed set of changes for that yet so you will have to wait for future announcements on how that looks.




As always If you have any questions feel free to ask here.

Hearts of Iron IV - PDXMidgeman


Hey Everyone! I am back this week to talk to you a bit about some changes we are making to air management and combat. The first thing I want to get out of the way is that this is not a “Man the Guns” style rework of combat and management systems. Our focus on air changes have mostly revolved around quality of life and balance changes to existing systems, while largely maintaining the structures people are familiar with (with a couple of exceptions). So, let's get into it!

Starting off with a QoL change I am very happy about: Simplified Wing Deployment. Anyone who has experience with managing air wings probably has some complaints about how deploying wings works. The live system requires three clicks in the best case (four if you include choosing a base) to deploy a single wing into an empty airbase. In the worst case this requires more clicks and doing some math for creating a large wing that can later be divided evenly. Now, we are adding quick deploy buttons to the air base UI to allow deployment of a wing in a single click. We are also keeping the old deployment menu for more advanced deployment options. Also, in this menu, we have simplified the flow for deploying single and multiple wings at once.

WIP UI design of simplified wing deployment tools. Note the art style here is not indicative of a change in art direction for our UI. In the first image we see the setup that can be done to select fast deploy options from any air base.



In the second Image we see the newer version of quick deploy within the advanced deployment menu. You now have a set of filters to only show planes of a specific type, and you can now set the reinforce preference on all of the wings you are about to deploy, or individual ones.


One of the most visible changes to air management, and hopefully a big quality of life improvement for most people, is the addition of Air Groups. The first thing I want to say is this is not Army Groups or Fleets. For now, and the foreseeable future, we are not adding Air Marshals or any sort of mechanical impact to using Air Groups. Air Groups are an organizational structure and nothing more. What it will do is enable the grouping and selection of multiple air wings across multiple locations bases for easier management. These groups will be displayed when in the air map mode so that you do not have to hunt down your wings on the map when you want to interact with them.

A very much WIP view of our current air groups


Of the changes we are making, one of the most notable is moving to standardized/fixed wing sizes. This change comes with a loss of flexibility in some situations and makes managing smaller numbers of airplanes a bit more complicated. However, I think that real air combat in HoI4 is measured in thousands of airplanes and not dozens. We are currently looking at 100 sized wings for most aircraft, with size 10 wings for a few specific equipment types(scout plans, CV planes, ect). This allows us to streamline wing deployment and some other management stuff such as not having AI take up weird percentages of air bases. It also makes balance easier and fixes a few exploit cases. This may take some getting used to but I feel it improves the overall experience of managing large numbers of aircraft.

The final change I want to discuss today is an addition to the combat system. We are adding a new mechanic for intercepting planes in regions enroute to their target. In most cases, engaging planes in their target region will still be most effective. But in others, such as when range is a factor, the region being crossed has a bunch of engagement and spotting bonuses, and in a few other cases leaning into combat in an intermediary region can be a good idea.

Beyond these more concrete changes we are doing a balance pass on existing air combat mechanics. A lot of this is still too WIP to discuss, but I would like to highlight one of our objectives which is decoupling agility and speed with more impact given to speed in later air superiority fighter designs, but more on that at a later date.

As always, I wish you all the best and don't hesitate to tell us how these changes make you feel. Until next time o7

Hearts of Iron IV - PDX Katten

Patch 1.11.11 "Barbarossa"

Balance:
- Adjusted the ship refitting cost calculation. The base cost is now a percentage of the hull cost, and the cost for any module changes are added on top of that. The same is true for tanks.
- Removed path connecting advanced light tank chassis to modern tank chassis research

Stability & Performance:
- Fixed rare OOS happening when players joined an MP game after playing a different game

Modding:
- Hot-reloading AI strategy plans will not crash the game.

Database:
- Changed the starting British Motorized Division template to use motorized - sorry, motorised - recon
- Added some bypass conditions to Czech focuses
- Unlocked fuel tank module for French cruiser submarines

Bugfix:
- Only display the ship refitting speed and cost modifiers when MtG is active.
- Added Bypass to "Demmand Lithuanian Annexation" if Poland already controls all Lithuanian states except for Memel
- Fixed units being unable to convert a move order to a retreat order when attacked
- Fixed CTD that could happen during railway gun positioning.

And we shall have peace...

Hi folks,

It’s been a while since our last update on future plans for HoI, but we’re about ready to show you some of the work we’ve been doing. Before we begin, I’d like to indicate that there’ll be some differences in how we do this. As I’ve previously stated, we want to begin discussion around features and implementation details a little earlier in the process than usual. This means a couple of things.

Firstly, while we’ll be showing off some individual features, we’re not yet ready to give an overview of the entire scope of our next release yet. This will, of course, be coming in the near (ish) future.

Secondly, you’ll be getting an early look at what we’ve been working on, and this comes with all the caveats you might expect: lots of WIP design, interface, and gameplay.

Lastly, for the time being we’ll be producing these ‘design corner’ style diaries every two weeks, rather than weekly. This is likely to change as we get closer to being complete.

Before I hand over, I’ll give you a quick run down of the directive for the feature we’re looking at today: Peace Conferences. Our primary objectives are to:

  • Create a system that appropriately rewards participation.
  • Allow for conflict and conflict resolution within the scope of the conference.
  • Create a limited ‘economy’ within conferences, where you may have to sacrifice your overall aims in order to secure immediate concerns.
  • Produce more ‘realistic’ outcomes where the AI is concerned

And with that, I’ll hand over to @Yaboi_bobby to dive into the deeper details!


Hey everyone, over the past months we have been working to overhaul the peace conference system. It is no secret that in HoI4 the peace conference system has a number of issues with how it functions. Combining that with the fact that it is a surprisingly hard interface to learn how to use, it is rightly one of our most disliked and complained about features. We have taken a large step away from how the system currently works and I am excited to show what the future holds for peace conferences.

The first major departure we made from the old system was shifting from absolute claiming of territory to contestable claiming of territory. In the old PC system once somebody claimed a state, that was it. That claim would be locked in and no one would be able to interact with it further. Now, players may contest other players' interactions in the conference. This doesn't come without cost. Contesting claimed territory will come with a point tax, and every time a contest happens the price of interacting with that state climbs further. This effectively creates a bidding war between all parties invested in a given state. This change should have some interesting outcomes, allow mid and low level participants to have more agency, and give players the tools needed to go after the states that are most important to them for things like achievements and forming new tags.

Contestable bids help solve some problems, but without further changes many still persist. One of the most obvious issues was how the old system handled turn order. The old system would order countries by participation, and then go in order based upon the number of points held by participants. Where it gets weird is the fact that the order of the list would get updated after each nation’s turn. This meant that often the top two participants could have enough points when a turn ended that they would simply exchange turns between them and end up completely controlling the conference. This was in some ways a good method to allow two big faction leaders to have majority control after the end of a historical WW2, but is bad in virtually every other case.

We did a lot of thinking about turn order and how to structure the turn in general. Slowly we came to the conclusion that any system with a visible turn order, no matter how it was structured, would put people at disadvantage or advantage depending on turn order. This led to the creation of what we have been calling the “Blind Bid” system.

The main concept of the “Blind Bid” system is that everyone acts simultaneously. The way this functions is that, each turn, every conference participant uses their points to make bids. When every player has finished making their bids, all of the bids are evaluated at once. Bids have a fixed cost much like the current claims do, but now with more modifiers. In any instance where two participants made a bid on the same state, that state is marked as contested and the players involved have the majority of their points spent on the bid refunded. Each time a state is contested, it increases in cost for all subsequent rounds. This effect stacks on a state each turn in which a contested bid happens. The other side of this is uncontested bids. Each turn a bid goes uncontested, it increases in cost for everyone else except for the person who made the bid. This acts to, over the course of several turns, lock in bids as they become too expensive to realistically contest.

At this point you may be thinking “Yeah OK, but I get points each turn, how does the conference end?” This leads us to the final major change: limited points. This is pretty self explanatory. Each participant will get a fixed amount of points over the course of the conference based upon war participation score. The way we do this is by distributing a percentage of those points every turn until all points are distributed. Most of the work here comes down to rebalancing war participation and finding what we consider a good point ceiling for a conference. Limited points will mean, in some cases, that loser nations survive more intact than they did previously, but this should not be a common case. In general, we think this creates a fun and somewhat tense conference experience.

Beyond the big three changes listed so far we have a number of smaller tweaks, adjustments, and rebalance to overall cost of interactions and participation. However, that topic is not worth going into at this point as it is still very much WiP. So with that I will conclude the first overview of the peace conference rework. We look forward to your feedback, hot takes, and hopefully excitement. Until next time o7
