Hello everyone!

Patch 1.10.2 of the "Collie" update is now live and should be downloading through Steam and Microsoft Store as we speak. The new checksum is f82d.
This update brings a number of bug fixes and balance changes to the 1.10.1 release of last month (see changelog below for details).

Saves made with 1.10.1 are expected to be fully compatible with 1.10.2 and you can continue your previous game without risk.

Should you still have an older saved game (from 1.9 "Husky" or 1.8 "Fork"), it will not be compatible with 1.10.2, even if the game does not report it as such. This is sadly an issue we could not fix in this patch without painful side effects (... Read more

Hello everyone!

Release 1.10.1 "Collie" is now live with its new features and bugfixes. The patch should be downloading through Steam as we speak. The expected checksum is dd56.

If you wonder if you missed patch 1.10.0, don't worry, you didn't! It was only released internally and to our beta testers, but the timetable allowed us to skip ahead and go live with 1.10.1 directly which includes a few fixes for issues found during beta.

Please note that 1.10 will not be save game compatible with 1.9.3. If you want to finish off any ongoing ironman games, please remain on 1.9.3 for now. Here are instructions on how you revert patch levels[forum.paradoxplaza.com].

As always please make sure that any mods you are using are updated for 1.10, or... Read more

Today's Dev Diary by Podcat[pdxint.at]


Hi everyone! This week is Hearts of Iron IVs 4th anniversary. I’ve got some cool data to share with you, new armor and radio packs as well as patch for you to celebrate! All of this releases tomorrow :)

A Look Back & Cool Numbers

It's crazy how Hearts of Iron keeps growing. I personally started with playing HOI2, and worked on HOI3 as a coder and game director on HOI4, and while people still call it a niche experience for WW2 buffs, it has also grown to be so much more (or us WW2 nerds are more numerous than we think :D). Around La Résistance release we clocked a new record on monthly players of 899k (the 1... Read more

Hi Everyone,

We've just released a tiny patch to resolve a security issue tied to the way LUA libraries were loaded for mods.
