HOI4 Dev Diary - Operations

Welcome to another dev diary for La Resistance. Today we are back talking espionage, namely Operations. These are like big impact missions that may require multiple agents as well as resources and preparation time. I also have some other stuff to cover.

Update on the new launcher
As some of you may have noticed the launcher release got a big bumpier than we had liked. While we had fixed several issues since the stellaris launcher it seemed that HOI4 had a share of unique issues also :/ I’ve looked at telemetry and it seems like mod use is mostly back to pre-launcher-release so it seems most players are back on board with mods, but there are still reports of issues. We released a 1.8.1 hotfix for some issues at the end of last week and we are working on a few things on the game side since. I have been chatting with the team working on the launcher and they will have a launcher bugfix patch out next week (the new launcher updates without us having to update the game or bump version number). While they are mainly looking at bugs at the moment, they are also working on some UI improvements for mod navigation that should be ready during next month.

Operations
Operations all require at least one agent to perform, and some require more than one (in fact some powerful ones require more than you might have as a non-spymaster, making their access more limited). They also all need some level of network to have been built up in preparation.

Operations all need preparation before they can be launched. This is usually produced equipment, agents or a cost in industry over time. We use this last one as an abstract representation of funneling economy into bribes, making or creating counterfeit cash etc where military equipment makes no sense.

In this example we are using the local resistance to saboutage resource extraction and we need to supply the operation with 250 support equipment
You can here also set the operation to just launch when ready if you do not care about timing, or if you want it to keep repeating.

Once preparation is done an operation can have multiple phases. The most common is 3 - Infiltration, performing the job and exfiltration. We have a pretty cool system for this where phases can be mixed and matched and have different costs associated with them. For example if your operatives need to paradrop into location at night it may require transport planes, but if its a neutral border perhaps only some economic bribing is needed to slip in. Operations can take quite a while to perform and will lock up your operatives during this. Operatives can also have traits that affect both chance of better outcomes as well as making them cheaper/faster.
The more times you perform an operation against a target the more difficult it gets. This kind of auto balancing simulates that the enemy will plug holes in their security based on how you have previously broken through.

There are two main types of operations: Gatekeeper ones that give you infiltrated assets, which in turn allow you access to other, more powerful operations.


Infiltration
These are all gatekeeper operations with added benefits.

(note that this resistance contact ones lets you specify a target state. Some operations target nations, some take states and others strategic regions)

Infiltrate Army - Gets you an asset inside the enemy armed forces. Gets you more info on their armies, techs etc.

Infiltrate Navy - Gets you an asset inside the enemy naval command. Gets you more info on their fleets, ships, techs etc.

Infiltrate Air Force
- Gets you an asset inside the enemy air force. Gets you extra intel on their air forces, air techs etc.

Infiltrate Civilian Government
- Gets you an asset in the enemies government. Gives more intel on their production, buildings etc.

Make Resistance Contacts - Get a local contact in the underground resistance. This helps boost resistance growth.

Other operations
Several of these require some form of infiltration to be in place first. Often they will need resistance networks, a certain amount network cover and other limiters also.

Steal Blueprints - Depending on the outcome and what kind of infiltration you have done you can get research speed bonuses, ahead of time or full unlocks of technologies.

Targeted Sabotage - Use your contacts in local resistance and strengthen and focus sabotage in an area

Boost Resistance - Strengthen the local resistance

Capture Ciphers - The old “steal the enigma” trick ;) Capture clues to the enemies cryptos and gain progress on cracking them. Requires that you have a crypto department.

Coordinated Strike - Allow setting up air strikes and launching a surprise attack. This will let us simulate things like Pearl Harbor and the devastation that the germans wrought on soviet air forces on the start of Barbarossa. Your agents prepare an area that will see a strong intial strike. You need to set up your air force missions before and when the operation triggers the strike will happen (and war declared if you are a nation allowed to do this). It works for port strikes and strategic bombing.

Plant False Intel - This lets you create “fake troops” to trick the enemy. These troops will look like regular divisions to the enemy, although they will disappear into thin air if the enemy gains full intel or end up in combat with them. They don’t consume supplies and are not able to capture territory. Fake troops work an all of your non-allies, but a nation needs to be picked where to seed the false information. Bonus point if you do this and put Patton in charge of them ;)

Rescue captured operative - Its bound to happen that one of your Operatives get captured while out on mission. If this happens they will be leaking intel to the enemy, but you will have the option to mount a rescue operation and get them out to safety.

There are also some things we will wait until next week to reveal...

Historical operations
We also wanted to give you the opportunity to recreate some of the more famous operations in the war. While the generic operations already cover a lot of work done by, for example, allied agents working with the resistance in France and Yugoslavia, there were a few very famous ones that didn’t really fit. Most of these are less inspirations for spy movies and more about Daring Commando Raids (™).

For example, if Germany occupies the Telemark region in Norway, they can now take a decision to begin heavy water production. The decision runs for a fairly long time, and if it completes, the Germans get a bonus to nuclear research. Historically the heavy water was fairly useless for actually building a reactor or even a nuclear bomb, but we decided that if the Germans managed to get it, they would realize that and end up pursuing a better approach.

However, any country with an intelligence agency in a war with Germany can try to sabotage the production plant if there is a certain level of resistance in Telemark. This is to allow the German player to successfully defend by keeping resistance low in the area. Historically, the British had to execute several operations to deny the Germans the heavy water. The most successful was Operation Gunnerside, which completely demolished the plant through the use of explosives planted by a small Commando unit, and which now serves as the basis for our Historical Operation.

There are a handful of other historically-inspired operations, including the German raids to capture or kill Tito and to liberate Mussolini.

See you next week when we talk... collaboration!

That's a great implementation of espionage feature. Thank you!

I'd like to remind, that (almost) every Russian player would be hyped to see soviet agent Maxim Isaev (Max Otto von Stierlitz). It would be realy nice. He is a fictional character, I know, but hey, it's HOI4 after all!
 
Perma sabotaged Romanian oil production ... RIP Axis fuel?

If that’s the case can us brits have James Bond added ;).

I would expect him to be extremely difficult to capture but of course if he does then he would escape eventually. Also he should get a boost to stats if working with a female spy.

Oh and he is of course unkillable.
 
Curious as to what the point of creating Phantom units in SP is. In MP, I get it, it might make it look like an area is heavily defended or troops are getting ready to attack there.
But what about SP? How will that work against a computer instead of a person? Seems like a MP only feature tbh.

it will mess up the AI, in most RTS games the AI is unaffected by the fog of war, otherwise its doesnt seem a "target" and stay stand. plus the current situation where AI blindly atack is already a big problem to be solved.
 
They need to add province features like Dams, Bridges, Railroads, Highways, etc. to the game first I would think.

Could just abstract it out to "infrastructure" damage.

Probably, yes. Thats what the resistance is doing anyway, even though they focus more on factories than infrastructure.
Factories are way more important targets than reducing infrastructure from 5 to 3

You say that, but picture late game MP where the axis needs every drop of oil they need. Lowering infra from 10 to say 8 on romanian oil hurts.

Sure but Infrastructure is repaired quicker than Factories, at least it feels to me like they do
 
This new espionage system is looking better and better all the time. Looks like we'll actually have to specialize and use limited resource strategically as opposed to just dumping spies everywhere and hoping some of them actually accomplish something before they inevitably die. Also, this:
 
If we have historical game enabled, will the British and Polish be able to crack the enigma code? Something that happened fairly early on and really affected the course of the war should be somewhat included.

Maybe let them get lots of ciphers at once?

What does getting all the ciphers do anyways?

Yeah you can abstract everything to an extreme extent and simplify everything...but I don't think that's interesting or fun. Also, I want a The Eagle Has Landed assassination of Winston Churchill please. :)

They should definitely have some kind of advantage or potential advantage in code breaking. The Americans too. The Allies cracked the German and Japanese codes and knew what they were going to do. At the Battle of Midway for example. It was a big factor in their success.

Edit: Just thought of another Operation to add. The planned Japanese strike on the Panama Canal with I-400 Class submarine launched aircraft. The really big I-400 class submarines need to be added to the game first of course. Also, there's an annoyance that needs to be fixed with the Panama Canal province. You can't land on the left side of it. Which means you have to go all the way around to the other side or declare war on poor little Panama.

The Finnish Signals Intelligence was also very skilled during WWII. A lot of Soviet messages sent by radio were detected and opened. Most of the Finnish Signals Intelligence material, equipment and personnel were secretly sent to Sweden when Finland made armistice with the Soviet Union, in Operation Stella Polaris https://en.wikipedia.org/wiki/Operation_Stella_Polaris
Nothing was left to to Soviets to find, if they would have occupied Finland.

Later some Finnish signals specialist served in the West, at least in the Swedish FRA, American CIA and the French intelligence.
 
Wasnt a Focus Tree for Portugal planned? Because on the DLC´s Steam Page this Part of the DLC isnt there anymore.
Portuguese focus tree was definitely planned, it was included in the features when the DLC was formally announced at PDXcon.

If it's not listed as a feature on Steam anymore, that's... interesting.
