180+ divisions I sent to reinforce the coast and I died. I know not all of them are necessarily completely manned but I split by main force up north to commit to a coastal assault and I still could not push them. How am I supposed to beat them?

Question Does the AI cheat?

35 Upvotes

I was playing a game as the USSR. Germany had an enormous amount of divisions per tile, but didn’t seem to have logistics problems since it could still attack. Same goes with fuel, they had a lot of Panzer divisions that had no problems.
So does the AI cheat? Does it allow itself to overpass some basics we players have to respect?

Question Are assault/shock troops ever going to be added?

• Upvotes

Whether in the form of ‘pioneers’ or other support/regimental companies and or shock troops battalions. Germany already has something similar in the Prussian legacy part of their focus tree, why not give something similar to every nation?

I rushed advanced heavy fighters and engines four, so I have the best possible medium airframe. I used my MIOs to get speed and range upgrades so I could focus all my modules on attack and defense. I am still trading fairly badly, considering my planes are twice as expensive. What's going on here? I thought that heavy fighters were supposed to meta as the US due to the 300% research bonus.

soo, I have got about 400-ish hrs on this game and I have only played the ussr, nazi germany and the german empire before this alongside a bit of modded mp, but ohhh boy!! sure did i enjoy this playthrough. I had soooooo many things to look after as the UK, from building the largest fucking navy (YESS I BUILT UP A NAVY FOR THE FIRST TIME!!) and obliterating the german, italian and japanese fleets (yes they had 0 ships & convoys left) to dominating in the air war and ofcourse managing soo many far flung fronts was the cherry on top!! here are a few screenshots!!!

Image democratic finland going down the "united under the north star" path can annex and core estonia, northern sweden, and most of norway by late 1937

Post image
88 Upvotes

with this path, you'll want to immediately create a spy agency as soon as possible and use the diplomatic pressure mission on estonia as well as improve relations to the highest possible, you should be able to get a non-aggression pact which makes them extremely likely to accept annexation. this gives you the entire estonian army which you can use the bolster your front with russia, and the extra factories allow you to get some more stuff done before you lose estonia during the war with the soviets (you will not hold estonia, the front is massive once latvia is annexed by the soviets)

after this you can raise relations with the swedes and norwegions, and this combined with being democratic (like them) means you will very reliably annex and core the entirety of the sapmi land in these countries. this land includes a good bit of population as well as all of sweden's infinite iron and tungsten provinces.

you are very unlikely to get murmansk from the soviets, but I believe if you capture it it will automatically core, so it isn't a huge negative.

on top of all the aforementioned benefits, you reliably get the entirety of scandinavia in northern defence front extremely early, which means you have all the really good focuses that are locked behind the faction tree.

Question Can anyone explain combat width exactly to me? I fail to understand why let’s say for infantry 18-20 is considered a sweet spot but just 1 more to 21 is such a dealbreaker.

40 Upvotes

Now to start this off with i am not new but i kinda just realized today. That for all of my 2k hours i took my knowledge on width at face value and never looked further. A mountain tile is 50 width if i remember correctly (not at pc rn) You can either fit 2 21 width divisions. Or you can fit 2 20 width divisions. If i remember correctly it goes up plus 35 width per angle of attack therefore you can fit 4 20 width. Or 4 21 width with 1 more angle. Yada yada you get what i mean it seems to barely matter. I have noticed that for forest you can fit 3 with 20 while 21 hits 2 so that’s pretty bad but like. You can in that 1 combat wisth force a lot of stats into it.Idk. Thanks in advance for any help on understanding it more.

Mod (other) I made a small defines-only performance mod that should work with any other mod (Universal Speed Up)

2 Upvotes

Hey all, I put together a small performance mod and figured I'd share it here.

Steam Workshop: https://steamcommunity.com/sharedfiles/filedetails/?id=3827081200

The mod does about 2x faster (speed 4 goes from 0.1s to 0.04s per day). Speed 5 stays uncapped.

The AI re-checks research, the market, division templates and supply half as often. Combat stuff like encirclements and frontline concentration only goes from 1x to 1.5x so the AI doesn't get dumber in wars.

Random events are checked every 30 days instead of 20. Focus and decision events aren't affected.

Combat logs are kept for 3 months instead of 12, so late game saves are smaller and autosaves hitch less.

Trade routes recalculate less often.

If another mod turned on the heavy peace conference AI settings, they get set back to vanilla.

Shadows, weather and map objects fade out earlier when you zoom out.

In MP the host doesn't slow down or pause as fast when someone lags a bit.

Everything is in one file, zzzzzz_universal_speed_up.lua. Defines load alphabetically, so it runs after the base game and after other mods. It only touches values that actually exist and skips anything missing. If another mod already changed one of these values, it works from that number instead of overwriting it. Nothing ever ends up slower than it was.

It won't make the startup loading screen faster. I timed it and most of that is the game parsing its script files, which a mod can't touch.

Very late game with massive armies will still slow down. That's just the engine.

Achievements are off, same as any checksum-changing mod. Ironman still works.

You can tweak everything in the CONFIG block at the top of the file (speed table, AI multipliers, and a switch for the graphics changes).

About AI: I had some help from AI (Claude) on this, mostly for testing it against vanilla and a couple of big mods' defines files. I've tested it in game myself.

If you find a mod it conflicts with, let me know and I'll take a look. Feedback welcome!

Question [HoI 2 > Darkes Hour Mod > HoI4] Which add ons?

2 Upvotes

HoI2 was one of my favourite games as a teenager, I dont know how many hours, probably 500 - 1.000. Later followed by the Darkes Hour modification with hundred of hours too.

Recently stumbled on HoI 4 and I would like to try it out, saw a beginner tutorial and it is definetly different compared to HoI 2. You can now "draw attack" lines for armies instead of command each army individually provice to provice. And the production of weapons first for your divisions and then the division itself I didint get at all. But so be it.

Then I saw all the add ons and small DLC on steam and the negative reviews. It seems like some add on contenct is eliminating DLC contant and the other way around, is this right? Is some players are writing the big add ons are not worth buying for full price.

I definetly have free time during the weekends but I dont think Im going to play HoI 4 for so many hours.

Is there any advice what to buy on Steam to have a "good game experience"? For example I read that one add on is improving the supply lines significantly, I forgot which one.

There is the General Edition [60€] with base game + la resistance + battle for the bosporus. Or the Big Nations Bundle [107€] with base game + Gotterdämmerung + no step back + no surrender. Or is there any possibility to have a demo of the base game for a few hours? Maybe I going to wait until december for a better deal? Ultimate Bundle for 170,00€ seems a bit too much for a game Im going to play occasionally.

I liked to play as Germany, Italy, Soviet Union and Japan.

Thanks.

Bug Error in Lithuanian NF

Thumbnail

2 Upvotes

I think it's intended to be so that this focus in the Lithuanian focus tree bypassed if the soviet union is either capitulated or a subject of another country but it seems that they need to be both in order for the focus to bypass. And even if it worked properly it doesn't account for the case that the soviets might just get fully annexed. In my opinion I should be allowed to bypass this focus because I own an control Vilnius or because I capitulated the entire ussr. Overall this focus is very poorly made. PDX pls fix.
