-------------------------About Me-------------------------

My name is Hammo and I stream on Twitch! I play a variety of RTS and strategy games, but my favourite game by far is Hearts of Iron IV.

I love this game and it's complexity, strategy and historical focus, but these are also reasons people can find it hard to get into Hoi4. The endless spreadsheets, statistics, buffs and debuffs can be overwhelming without someone to show you the ropes, which is where this channel comes in!

I will be creating and posting beginners guides, tutorials, walkthroughs, tips and tricks videos, just about everything I can to get you playing and enjoying Hearts of Iron IV as much as I do!

The new DLC "By Blood Alone" has significantly lower the production cost of transport planes. A single air wing of transport planes can supply an entire region by itself.

Hammo, have watched numerous vids on supply, and not one of them has addressed, or explained, how to get supply up when you go overseas, such as the USA to Europe-China. They insist you build a naval base, and yet when you check supply, many times it is not even being delivered to the naval base you built. Also, when going to an existing supply hub in a foreign territory, it is always controlled by another nation, so you can NOT click on the hub and upgrade railways back, you must manually upgrade the railways back to the naval base, but there in lies the you can NOT choose which naval base for your country to send supply to, you might have to upgrade railways across the continent to where it is being supplied, and there is no promise that base is where supplies will be sent to in the future. This means you have spent loads to build the railway, and now it is not viable for supply from your country as the AI has switched where it is going. Any thoughts?

Your guide for hoi4 has finally got me into the game after owning it for years. Attempting a few starts over that time but pretty much abandoned it. So glad i watched your content as its finally got me playing this amazing game. Thank you!!!

Quick tip, if u got a good economy like Germany, u can just upgrade small parts manually so u can do a whole railway in faster amount of time instead of putting 15 factories on 30 railways taking 2 months just put 100 factories on the same 30 railways just seperated and let it take 4 days

[MrJbstiles]

This helped me a ton. Really enjoying your tutorial videos.

[remyrollo]

I really enjoyed this video thank you!

[emicomel]

Very very helpful. thank you, good sir!

[farkasszabo]

Nice explanation! Could we say in a nutshell that trains bring the supply to the supply hubs, and trucks take it from the supply hubs to the divisions?

[Thumper]

What about transport planes set to supply drop? How does that work?

[lenord]

Very helpful information, thank you. Just one suggestion: could you please slow your presentation a bit to reduce the need to go back and listen to parts.

[AnimeQuickyz]

I clicked on the supply hub but it didnt show me the upgrade thing. Is it patched?

[taner]

hey man, is there any reason not to increase supply priority to the double trucks?

[BigBossXCV]

I don't understand why for istance if the supply hub is 1/15 (so it's not overloaded) the units next to it keep having low supply anyways

[mesterb]

Thank you!
Got a small question
Im doing most of the things you said, also have BBA but on war the front always have low supplies! I focus on taking enemies supplies and cities but in some cases they still suffers. Any tip to prevent this?

And also support airplanes are still worth it?

[MistaFadora]

Next time say the controls, u just saying to spread them out didnt really help, i still dont know how to do it.

[dsx]

The fact that the supply line always starts in the capital (and can't be distributed to more locations) is so stupid and unrealistic, I can't even....
