HOI4 Dev Diary - The Intelligence Agency

Hi everyone! Today we will start going through the Espionage features announced at PdxCon in greater detail. First off is the hub of everything - Your Intelligence Agency.


The Agency
The Agency is something you need to construct on game start if you plan to involve yourself in the shadow war that will be running now. We recommend at least an investment in defence eventually to help protect yourself even if you do not plan to dedicate resources to offensive operations. Notice that I said ‘construct’? The Agency will take up several of your factories for a while to be created. Civilian factories is the closest we have to a money budget so we felt this was the most appropriate cost to use. When you decide to make the agency you are free to name it (a historical name will be suggested) and you can also pick from a mix of historical logos as well as generic made up ones (surprise - a lot of agencies did not advertise themselves to heavily).

In the Agency you can recruit Operatives (more about them and what they can do in a future diary), work on cryptology (also a topic of a future diary) and upgrade the different branches of the agency as well as update training or develop new gadgets to help your Operatives.


Branch Upgrades
Just like the creation of an agency it will cost you some industry time to develop its capabilities. The time is always the same, but the cost itself can vary with how powerful the option is.

Lets have some examples of the many options:
  • Naval Department - This is one of the basic branches that improves your intelligence gathering in that field. It will ensure that you get the most out of any naval intel you get.
  • Passive Defense - This boosts your agencies counterintelligence rating which together with Operatives help you defend against enemy Operatives.
  • Invisible Ink - Improved ways of sneaking intel back through letters or other ways through writing. It means your Operatives will be generating more intel when active somewhere.
  • Suicide Pills - Captured Operatives will now have a final way out limiting leaks of intel to the enemy
  • Diplomatic Training - Operatives learn to operate among high society and politics and would no longer dream of ordering their Martinis stirred. This one helps with missions such as diplomatic pressure and control of foreign trade (yup.. future diary)
  • Cryptology Department - this sets up a department of math wizards and crossword puzzlers. Why shall be covered in a future diary ;)

The Spy Master
If you have enough upgrades and are in a faction you can become the faction’s Spy Master.

This is the logical path for people who want to lean heavily into espionage to get the most of it. There can only be one spy master per faction and the main advantage of being a spy master is that it will let you run a lot more Operatives (how many depending on the size of your faction). We felt it was mostly historical that only the really big nations truly invested in this, but the most important reason was balance. A lot of spy systems in games fall down on the fact that people can spam you with agents so you either end up super annoyed or the system needs to be toned down to where it’s no longer impactful and fun. In a historical HOI game given this rule, we have then set us up with 3 potentially powerful agencies: Allies, Axis and Comintern.


See you all next week when we take a look at further espionage topics :)
Rejected Titles
  • HOI4 - Mirai Nikki
  • This dev diary will auto-destruct after being read, please stand back.
  • Popping pills & blowings stuff up with government funds!
  • Renamed to iAgency for the Mac version
  • The Department of Ungentlemanly Warfare (™)
  • There is no department called Military Intelligence because we don’t do oxymorons
  • We didn’t manage to make the icon for Commando Training be a man being hit in the nuts, but based on our research 50% of the training seems to have been this.

Will majors that had important Intelligence Agencies get some kind of advantage through their focus tree to advance in the construction of their agency. The United Kingdom and the USSR had important Intelligence networks but those 5 CIV might be needed elsewhere
 
Yay now I can play I spy with the Germans.
I spy with my little eye 5 divisions of heavy tank. Not getting around the Maginot this time.
 
Given this seems to be based on controlled factories, does it mean that Governments in Exile won't have access?

We havent quite decided but as it stands now you need to have invested before you lose to keep the agency going because you wont really have the industry to start one after going exile (unless you are someone big like france etc)

mhm 5 to 8 civilian factories for only 30 days seems nothing, atleast for Germany or USA. Since you have atleast one hundred civs, as Germany maybe even much more, depends on how the occupations system changes.

Here again you talked about the three big faction of Axis, Allies and Comintern, but I still ask, what about the Co-Prosperity Sphere under Japan? They are quite limited in their civ count.
Japan will probably be a bit behind (as is historical) given their position. A player can turn that around tho I think

Will any country start with an already developed agency? Will there be any modifier to reflect the historical USA's insight into Japanese intel?
Nobody starts with an agency. USA will have more industry and Japan probably wont so it will naturally have a crypto advantage. Historically the japanese didnt take that stuff as seriously at all and didnt really form a espionage agency like the allies from what I know.

Can you elaborate on the whole Spy Master thing? What does it entail? Would it be complex enouhg that a player might be chosen in a multiplayer game to take care of it much like Air Controller?
If you max out everything and have 10 or so agents it can take some headspace. Nowhere near the other parts of the game but a bit considerign the economy feeding into it (future stuff....). Making it a formal thing like people often do with air in MP was something we figured people would be familiar with and let people pick exactly how much they wanted to invest of their resources and time.

Will cryptography be removed from research and moved into intelligence agency completely? If so, how will Engineering research change?
Some of those techs are going away, some we might keep to help bonus some stuff in crypto. There is a later diary about all this.

How much can Minor countries get involved in espionage, as they have a small factory-pool in the early game and need way more time to develop a good espionage?
They are likely to get involve less. Espionage can be a force multiplier but if you are small your main objective must be to get that force first

Will neutral countries be able to sell/give their Intel to others? Would be useful as USA.
No, but its an interesting idea!
 
I think game needs a money mechanic badly.

It can be done by having civilian factories producing money. More civs more money. Of course contruction still be the same.

Because using civilian 'factories' to establish departments sound silly.

If the Hindenburg wasn't destroyed therefor alt-history is enabled can Rommel defect to the British, he was thinking about doing it.

Maybe you guys should seriously consider revamping the economy in the game and include actual money. It would give you an opportunity to make Fascist/Communist/Democratic countries play differently from each other.
 
Passive Defense - This boosts your agencies counterintelligence rating which together with Operatives help you defend against enemy Operatives.
Looks like we should hope to live up to the highest standards of the KGB- er, NKVD. <if you get my reference.> :D

Naval Department - This is one of the basic branches that improves your intelligence gathering in that field. It will ensure that you get the most out of any naval intel you get.

Cut off one head, two more shall take its place. Hail Hydra. :D

Alan Turing will be happy with this.

In a historical HOI game given this rule, we have then set us up with 3 potentially powerful agencies: Allies, Axis and Comintern.
@podcat, so I presume if there are more than 3 factions in a game (Allies, Comintern, Chinese United Front, Central Powers, Hispanic Alliance, etc.), then there would be multiple powerful agencies as well? Or are these powerful agencies limited to just the typical 3 factions?

Overall, can't wait to try all the Espionage mechanics. Well done, Paradox! :)

In what way does that affect anything?
Say 1 civ produces $1 per day. Well, now you simply replace the cost of 5 factories for 30 days with $5 per day for 30 days... What did you gain by this?
 
I can't wait to play my "shadow" Canada, only building planes and investing massively into spying ! :rolleyes:

And France... Oh France... Will be so great ! Never been hyped as I am now for an HoI4 expansion !

You can decouple economic output from being so automatically the same as industrial output. Your revenue from each factory could vary. You could stockpile cash reserves.

Unrelated, but when did they change the button icons?

So if there are more factions they will be smaller, limiting how many agents you have. So it balances out.

@podcat When will the weekly hoi4 streams start, showing of the expansion?
Turns out after the office move that we dont have our streamign studio working yet. we are looking into options and I will let you know when we know :)
 
Will intelligence agencies interact somehow with military operations? I will be nice if you could get info of where the enemy is preparing an offensive, like the soviets getting info on the Kursk offensive and being able to prepare for it. And you could spread misinformation that an offensive is being prepared somewhere else, and the AI could choose to believe or disregard info, such as Stalin thinking that operation Barbarossa was british misinformation to provoke war between Germany and the USSR.
