Hi everyone!
The game has now been out for a bit under a month and we have released the first big patch yesterday. This year has been hard work, but also incredibly fun to finally get to release the game we have worked on for so long be successful. As you probably know us swedes like vacations and it's now time for us to get some rest for a month and return full of energy to work on the game again.

This means that you will likely not see as much presence on the forum during this time as you are used to, so I figured I'd give a heads up.

After vacation we will be working on 1.2 patch or 1.1.1 if a hotfix is needed. AI and balance will be priority but we also have some nice ideas for increasing difficulty and replayability and such for players who have already mastered the game. More info on that in august.

Enjoy your summers and many thanks from the team for supporting us!

p.s fun statistics about HOI4: about 30% of games played are using minor nations. This is really great to hear because one of my goals when designing HOI4 was to make minors fun and playable.


(ARMORIOS playing Germany, although his invasion ended in flames for him it looked neat :) )

Known issues:
- Using "observer" mode from console in single player will break AI behavior. It should be fine for its intended purpose in multiplayer after having lost still as long as you observe players.

Enjoy!

Hi everyone and hope you are enjoying Hearts of Iron! The team has been busy working on the 1.1 path that we have decided to name "Red Ball Express" (since we thought it was a cool idea from Stellaris team to use names, we will be doing the same for major patches). The idea is to have the patch out before we go on vacation in July, so expect it one of the last days of June with a open beta patch some days before to make sure it goes smoothly.

I'll be presenting some of the more important stuff we have done so far, but we have of course also fixed minor bugs, optimization, crashes and the like. Next week will have a diary with the full patch log and I'll talk about the other stuff we have done also.

Access to allied territory
One of the biggest talked about issue has been the fact that as long as you fight the same enemy you automatically gain military access, even from other factions. This was kind of a bandaid for an old issue, and we never liked it either... so we have been listening and working on a solution. The way things work now is that you will be requiring military access as expected and the game will also alert you if you end up in a position where you are trying to move into occupied area you don't have access to (as this for democracies would liberate those nations you will need to ask for permissions, which ai will give you). We are still testing our solution, so there might be further changes still.

Peace conferences
We fixed a serious issue where instead of taking turns in a peace deal when there were 2 major contributors it would instead end up so that the 2nd of those gets to push through almost all changes in the peace deal. This could lead to some really weird peace deals. Now you will instead get to take turns (as well as do a little more per turn if you are close in points). Hopefully this should make peaces feel a lot more sane and rewarding.

Invasions and Naval bombers
When it comes to invasions and ease of reinforcing invasions into Germany we have now made Naval Bombers able to attack troop transports (before only fleets could stop them, which isn't a great option for Germany when facing the royal navy obviously), so you only really want to do invasions with sufficient control over the skies. AI has also been tweaked to prefer several larger invasions at once to pose more of a threat to players and bleed less troops in smaller invasions. I've also been looking at general balance around naval bomber and other air war being a bit too bloody, but I'll give you an update on that next week instead because it's not done.

AI
When it comes to further AI improvements, I'll hand over the mic to SteelVolt:

This path we have taken a look at some things in the AI where relatively small effort would give a rather big payoff. A lot of this focus was around mistakes Germany was making, such as building too many dock yards and thus lagging behind in the production of military factories. Another thing we discovered that Germany did was to start using the Austrian division designs after the Anschluss, due to looking at the latest date edited. Both of these have been taken care of, but we have also looked at how to make them not rush the maginot line without making large changes that could break other cases.

Aside from this I have been working on keeping the AI up to date with some rule changes we have made for this patch, such as the "enemy of my enemy access" rule.

I am also very happy to be able to introduce a new feature today. When working on how to improve the warfare AI I realized that it would be very beneficial if there could be different modes of plan execution. While something along these lines had already been discussed, the intention was to have it in a later patch as we expected it to take some time. But as the AI needed at least something basic like this I added three modes, and to test them I added some buttons in the order group interface for it.
As it turned out, it worked so well that we are making the feature available for players as early as patch 1.1!



The three modes are as follows:
Careful: The units will not attack heavily fortified locations (what counts as heavily fortified is set in defines, so modders can tweak this) and will not attack provinces that has a score below 50 on a scale that goes to 255. This means that if a part of a front has level 6 manned forts, that part will not advance at all unless micromanaged. It also means that they are significantly less likely to push into provinces that would end up very exposed or extending the front line.

Balanced: This is the default mode, and it works exactly as it does already in the game.

Rush: The units will aggressively advance into provinces that are part of the order. This mode is ideal to quickly crush weaker enemies that would be unable to mount a proper counter attack anyway.

I hope you enjoy this new feature. Defines have been added for score limits for the different modes, as well as fort levels for the careful mode. Please note that this only applies to how land battle plans are carried out.
Of course, there are also various minor tweaks here and there

See you next week everyone when I'll talk about other changes in the patch!

Oh, and if you missed the three day war, the multiplayer skirmish featuring Enter Elysium, Quill18, Marbozir and Arumba, then you can check it out here.
