Hearts of Iron IV Dev Tracker

Hello, and welcome back to another Dev Diary for Hearts of Iron 4. As we close in on wrapping up this major operation, code-named Barbarossa, before winter falls (the first snow fell in Stockholm this weekend, I am sure it’ll be fine), today we will talk about the new achievements that will be added with the release of No Step Back.

As far as the process is concerned, we usually have an open list of achievement suggestions during the whole DLC development cycle. Near the end of the cycle, we take a vote on what achievements we want to see in the game (after eliminating any that would be technically impossible) and start the process of implementing them and ordering art.

For No Step Back, we started with a list of 49 suggestions, and whittled it down to 20 Achievements:

Hello everyone, it's your favourite (and only) tech lead, The French Paradox!

In this diary I'll tell you more about our tech, give some insights into the programmer's job, what we've been up to for the past year (and some change) and offer you a chance to ask any question you may have about tech.

Saying old platforms goodbye

First, with the upcoming 1.11 patch we will be retiring some old Linux and Mac platforms that aren't maintained by their own developers anymore.
This means that starting next update the minimum OS version to run HoI will be Ubuntu 18.04 (on Linux) and macOS 10.11 (El Capitan) on Mac.
There shouldn't be much to worry about though, as the previous versions are older than HoI itself at this point and our telemetry shows almost all of you have upgraded long ago.
For those on Windows who l... Read more

Greetings, HoI fans.

I'm not much of a forum goer, so most of you probably never heard of me, but I am the Art Lead on Hearts of Iron 4.

Today I bring you a rather special Dev Diary. This was prepared for you all by our 2D artist on HoI4 and should give you a glimpse into the work that goes into each new loading screen. We hope that you will all find this to be an interesting and enjoyable read.

Without further ado, I now hand over to the artist.

So where does an artist start?

First and foremost, to have a tool to gather the most crucial thing to build an epic looking loading screen is a reference board. The tool that our artist uses is called PureRef. It keeps track of your images and is easy to organize and customize.

Hello, and welcome back to another Dev Diary for No Step back and 1.11 Barbarossa. Today we will be pulling back the veil a bit and show you how modders can affect and use the new features coming in 1.11.

For those of you who do not get unreasonably excited by hearing about new script commands and changes to databases, the long and short of it is this: We made some fundamental changes to the way the game handles some things, which will probably require your favorite mods to spend some time updating. On the flip side, those changes also allow for some exciting possibilities down the line. If you came here hoping for a release date, we must ask you for just a little more patience. We promise the announcement is very close - but not today.

Probably the biggest change is in how we handle people on the backend (or ... Read more

Hi all, and welcome back to today’s developer diary!

It can be very easy to get super-focused on details when looking at individual systems or parts of features - something we often tend to do when writing developer diaries. Each week, we’re going to give you an overview of a core system that we’ve so far introduced in parts, and will include all of the changes we’ve made to that system over the course of development, since we first looked at it.

In addition to this, we’ll also take a look at some changes coming to the AI in No Step Back, so if that’s more your jam, feel free to skip to the end ;D
We’ll begin with an overview of the Officer Corps:

Welcome to this AAR dev diary!
Join me as I take on the task of surviving as Poland against both the Soviets and the Germans in the upcoming No Step Back expansion. This diary will function as a sort of compilation of the new features. Normal caveat is that there might be bugs here, and balance are prone to change. It's also a pretty screenshot heavy diary.

Without further ado, let's start.

1936 - The year of housekeeping​ First off let's start with some housekeeping and strategy. I know that Germany will attack first and I can’t properly defend against both the USSR and Germany. My plan is to give up eastern Poland when the USSR demands it to buy myself time and take out Germany, then swing around and take back my lost land.

Therefore I’ll focus my industry buildup on western Poland since I plan on losing eastern ... Read more

Greetings all,
Today we have two important topics to cover, for which we have reinstated @podcat with a battlefield commission, in order to detail our latest efforts to combat the width meta. In addition, Comrades @Bratyn and @Wrongwraith return for a dive into changes to the Soviet Exiles branch of the focus tree, based partly on community feedback.

Combat Meta
Hi everyone, @podcat here for a little guest appearance to tell you some more about the combat changes coming with Barbarossa. Back in the Combat and Stats Changes diary we outlined our quest to break down the 40 width meta and try to combat an “overall best division”.
In there we outlined several changes such as varying terrain width without easy multipliers to exploit (meaning you can still make optimums for particular terrains but not all), as well as reduce... Read more

Greetings all!

Today’s dev diary contains the details of a few smaller features coming to the table in No Step Back. In addition, I’ll get ahead of the curve here and point out that there will be no diary next week - we’ll be back the week after with more to see.

Scorched Earth
One of the enduring tactical practices of the Soviet defense during the German invasion, was the use of scorched earth. In No Step Back, you’ll be able to spend Command Power on ordering the strategic disabling of railways in the event of a tactical retreat.


(All visuals WIP!)

Enacted on a state level, every railway present receives full damage, and is immediately flagged, making sure that... Read more

Hello there, C0RAX again.

It’s time again to reveal some more secret information that was hinted at in the last dev diary. Specifically this week will be revolving around the final part of railways and trains. So without any more need for introduction here are our stars of the show today.

The railway guns.

So to start off I'll go through how you get a railway gun on the map because it’s a little different to normal land units. First of all you are going to want to research railway guns which comes after armored trains



Then you can find it in your production tab just like building normal equipment. But unlike other equipment you build, these production lines are limited to 5 factories and the railway gun won't be added to your stockpile.
