Downloadable content
For music, cosmetic packs or e-books see Downloadable content 2.

Downloadable content (DLC) is content built by Paradox Development Studio (PDS) as an extension or add-on to Hearts of Iron IV. They are modular in nature,[1] which means that a player can choose to play with or without a given DLC by checking them out at the launch menu. An expansion DLC is normally accompanied by a free patch that gives players most of the new content as not to hinder the playability of the game. As such, most DLCs are seen as optional content for players who wish to have a better gaming experience in exchange for some monetary support.
Multiplayer games also benefit from this compatibility, that is to say, if the host has a gameplay DLC (expansions and flavor packs) the player does not, the game acts as if the player has it.

Base game editions[edit | edit source]
The base game is required for any and all DLC relating to the game. While cosmetic/music DLCs can be used with any game version, content DLCs can't be used prior to the version they were released with.

Country packs[edit | edit source]
Country packs are expansions of a smaller scale. Unlike regular expansions which focus on adding new gameplay mechanics country packs' main focal point is on adding more flavor to the game (in addition to the accompanying free patch).

Music, cosmetics and E-books[edit | edit source]
- Main article: Downloadable content 2
Additional content is available for the game in the form of music and cosmetic packs, as well as e-books for reading outside of the game.
Summary[edit | edit source]
- ↑ New flavour countries generally receive a National Focus tree, ideas (such as political advisors and design companies), unique generals and admirals, 2D pictures and 3D models of their equipment, unique decisions and events, and music inspired by these cultures. Voice overs (activated when a player clicks on units) are added if they are not in the base game.
- ↑ Reworked countries already have unique content in the base game (or an earlier DLC), but here they receive additional alt-historical branches in their National Focus tree, additional decisions and events, and (except for the UK) a unique mechanic to model the politics of that country.
