HOI4 Dev Diary - Man the Guns and PdxCon

Hi everyone! We are now back from PdxCon which was an amazing experience. If any of you were there, thanks a lot for coming! I had a lot of fun and interesting conversations with HOI fans and we had a very cool challenge to as Poland inflict as much casualties as possible on Germany in 1939 in just 30 minutes. The winner (all glory to @Zwireq, AKA Zwirbaum) pulled off 1.8 million using clever tactics and a strong cavalry army! What better way to save Poland than to turn the false myth of the polish cavalry charging German tanks around :)

The myth itself is something based on reality where polish cavalry performed a successful charge early on in the war vs German infantry at the battle of Krojanty. Something the German propaganda machine tried to falsely portray as the poles being unprepared for meeting modern German armor (there were no tanks there). The myth apparently lived on a long time, notably taught in schools and promoted in soviet propaganda… that said, in Hearts of Iron IV at pdxcon the polish hussars did ride out and win!

We also announced the next big expansion for HOI: Man the Guns.

Man the Guns will focus on naval warfare primarily but also redoing UK and USA and giving them more fun options. There will also be other new focuses but those are secret for now. We will also be adding fuel to the game which a lot of people were very excited to hear about at pdxcon :)

The UK and US revamps we plan to handle the same way we did Germany and Japan, e.g the changed trees and historical path in the 1.6 'Ironclad' update and the new alt-history paths (despite my perhaps not so subtle hints people have figured out that there is going to be the possibility of a 2nd american civil war among other cool things).

As for the themes we decided to go with naval for several reasons. One, that it fits very well with USA (and they were on the top of our list of nations we felt needed more fun gameplay). Secondly we have already done big changes to both land and air in previous expansions and updates so it was time for the 3rd type of warfare to get its time in the spotlights. Its also currently in my opinion the weakest part of HOI and something we really want to make shine.

We are currently very early in development so things may change, but here are some things mentioned we are aiming to do (in expansion or free update or mixed):
- Ship design and the ability to refit older ships and keep things up to date
- Naval Terrain: different seas will behave differently and suit different ships and fleet compositions
- Revamped naval combat
- Fleets split up into task forces for better control
- New naval spotting system
- Ability to control naval routes and block areas you dont want units to travel through
- Fuel, obviously going to be a massive balance job for us and a big gameplay change for you :)
- Gameplay rules, particularly to help multiplayer groups out when it comes to manage their games
- of course other stuff as well. to be revealed in the future.

We don't have a release date yet, and most of the above is still subject to change because we are are still early. I really wanted to talk as much as possible about what we are up to at pdxcon though :) Hopefully I will see more of you next year there!

We also announced that HOI4 has hit 1 million sales (wooot), and to celebrate that we have decided to make an anniversary edition that comes with a super cool alt history diorama - Italian soldiers raising the flag over the rubble of Big Ben, Iwo Jima style ;). I felt italy invading London was one of the more hearts of iron things there was when it comes to alt-history :)

We had the first version for PdxCon in the booth fresh from the maker, and you can see it there in the picture above. The anniversary edition is actually possible to preorder already! Just follow this link.

As have been mentioned elsewhere this doesn't mean we are ready to start up regular diaries yet. You guys are not really fans of filler stuff, so we are going to have to wait a little longer for diaries to start up regularly again. I will let you know as soon as we feel ready to start showing things off proper.

Under the terms of the Treaty of Versailles, Germany was forbidden to build submarines. Everything changed in 1935 after the establishment of the Nazi regime and with the signing of the Anglo-German Maritime agreement, in which submarines were recognized as obsolete weapons, which lifted all prohibitions on their production. In June, Hitler chose Karl Doenitz, commander of all submarines of the future of the Third Reich.
During its relatively short existence (about nine and a half years), the German submarine fleet managed to write itself in military history as the largest and deadliest submarine fleet of all time. German submarines, the dreaded captains of seagoing vessels from the North Cape to the Cape of Good Hope and from the Caribbean sea to the Straits of Malacca
German submariners were characterized by courage and professionalism. Among the ACE submariners of the Third Reich, the most famous were the captains Otto Krechmer, Wolfgang Lute (each with 47 sunk ships) and Erich Topp – 36.
As part of the Kriegsmarine fought 1154 submarines built at German shipyards (including the u-a submarine, which was originally built in Germany for the Turkish Navy). Of the 1,154 submarines, 57 were built before the war and 1,097 were built after 1 September 1939. The average rate of commissioning of German submarines during the Second world war was 1 new submarine every two days
During the Second world war, German submarines sunk 3083 merchant ships with a total tonnage of 145,8570 tons.The most productive submarine is the U-48, which sank 52 vessels with a total tonnage of 307935 tons
Officially, Spain was neutral, but unofficially was on the side of the Nazi coalition. In 1940-42 Spanish ports became filling stations for German submarines.Also, German submarines were supplied in the ports of Argentina, will all this be reflected in the new addition?
 
Well that's one possible good piece of news at least. If the China warlord thing can't be fixed, could you have a look at the carrier plane/naval warfare bug that was introduced in 1.5.3 at least. Thanks

I would assume that will be fixed in the course of the naval combat rework.
 
@podcat Could we have a dedicated dev diary on that recently announced HOI4 board game :) ?
 
Is there any posible that should be a change in doctrine system, in specific over land?

Additional Effects ver.English MOD has an interesting aprouch as a basic view of a way to have a more flexible doctrine system divided in offnsive doctrine, defensive doctrine and general planning. The problem is the lock/unlock tactics from tech in doc techtree make a hole problem. theres isnt even a single command for force a specific tech to ve intant eveloped to solve the problem.

If this were avaible lock/unlock tactics from law tabs, even as a modder capacity for test is very posible to have a better usage of tactics and defense phase of global wars that many players were looking for. I dont think it would be a masive block of new code needed to have this feaure even if in vanilla game wasnt used.

Im very happy with the tigers changes and the final usage of fuel for next dlc. Is the right path.
 
It's licenced product and is AFAIK not developed by PDS in any way/or form - so best way is to contact board game developer directly
I posted on their forum suggesting they write a DD and publish it here :) .
 
This. I would have torn my hair out if someone had walked in my office and wrecked a project plan doing a revert this far along.

It only means that your process is inflexible.

And that you can afford that. When you have a small number of serious clients that pay a lot instead of many clients that pay little/nothing, the process magically becomes much more flexible, for example.

Moreover, there are sometimes cases where maintenance of an old build and development of the new build goes in parallel by different teams - and not only for putting down fires, but on ongoing basis.

It is understandable why PDX wouldn't do that, but no need to portray it as something that is set is stone.

I was taught this myth as fact around '97 in a British state school. I actually believed it was still true until reading this post as the misinformation has never been corrected.

Heck, even some non-communist Poles propagated the myth, albiet they did in a manner which portrayed it as an example of courage and heroism in the face of bad odds instead of as a "lol, Poles are stupid". Sometimes, a myth is such that everyone can find some interest in it's propagation.
 
Since this is a naval focused DLC, will we be getting admirals with traits or multi class navies?
 
Oh wow! I'm so excited to see what your take on "Naval Terrain" will be. I'm excited about this! Also, please have an adjustable gauge for naval spotting system(scout planes, etc.) which affects spotting chance and attack damage or something, that played a big role in how battle of midway was won.
