Hearts of Iron IV β a WWII grand strategy where you rewrite history
Hearts of Iron IV is a real-time grand strategy game by Sweden's Paradox Development Studio, released on June 6, 2016. You take command of any nation on Earth across 1936β1948 and lead it through World War II: build factories, design divisions, forge alliances, run diplomatic schemes and push frontlines across a vast world map. There's no fixed script β Germany can lose in 1939, the USSR can collapse from internal opposition, and a small neutral country can rise into a superpower. Every campaign writes its own alternate history.
This page gathers Steam keys for the game itself, for editions that bundle it with a set of DLC, and for standalone DLC. You receive an activation code, enter it in Steam, and the content lands in your library. All items are for the CIS region.
What the base game gives you
The base Hearts of Iron IV is the core without the major paid expansions, yet it still holds hundreds of hours. Inside: the full world map split into provinces and strategic regions; a national focus system that sets each country's political and military path; production chains from raw resources to tanks, planes and ships; a combat model spanning land fronts, air and navy; ideology mechanics (democracy, fascism, communism, non-aligned) and multiplayer. The base alone is enough to fight the war as any major power β Germany, the USSR, the USA, Britain or Japan.
Editions: General Edition and the all-in-one start
If you'd rather not assemble a collection piece by piece, take an edition. An edition already includes Hearts of Iron IV itself plus a selection of DLC in a single key β a convenient way to start with extra content without buying the base separately. It's the best pick for a new player who wants the game and some of the key DLC mechanics in one order. Each item in the "Game & Editions" tab spells out exactly what's inside.
Major expansions: where the game truly opens up
The strength of Hearts of Iron IV lies in its expansions, each deepening a region or a system. The key sets in this catalog:
- La RΓ©sistance (2020) β espionage, intelligence agencies, covert operations and reworked focuses for France, Spain and Portugal.
- Battle for the Bosporus (2020) β a country pack for Turkey, Greece and Bulgaria with new Balkan focus trees.
- No Step Back (2021) β a big Eastern Front expansion: USSR and Poland reworks, a tank designer and an officer corps system.
- By Blood Alone (2022) β an aircraft designer plus focus trees for Italy, Ethiopia and Switzerland.
- Arms Against Tyranny (2023) β the Nordics (Finland, Sweden and more) and military industrial organizations.
- Trial of Allegiance (2024) β South America: Brazil, Argentina, Chile and their paths through the war.
- Graveyard of Empires (2025) β Central and South Asia: Afghanistan, Iran, Iraq and India.
- No Compromise, No Surrender (2025) β the Pacific theatre: Japan, China and the Philippines with a doctrine rework.
π΄ Keep in mind: all of these are add-ons. They don't launch as a standalone game and attach to an already-installed base Hearts of Iron IV. If you don't own the game yet, grab the base or an edition first.
Cosmetics and music
A separate category covers vehicle skin packs (Axis Armor, Allied Armor, Eastern Front Planes, Prototype Vehicles) and music packs (Allied Speeches Pack, Songs of the Eastern Front, Radio Pack). These are cosmetics and soundtracks: they change unit looks and add tracks, but they don't add nations or mechanics and aren't a separate copy of the game. They too need the base installed.
How to activate a key in Steam
The flow is simple: open the Steam client, go to the "Games" menu β "Activate a Product on Steamβ¦", enter the code and confirm. The game or DLC appears in your library. Mind the region β every key is for the CIS, so activate it on a Steam account registered in a CIS country (Russia, Kazakhstan, Belarus and so on). The game has native Windows, Linux and macOS builds and runs on Steam Deck β after activation Steam picks the right version for you.
Who it's for
Hearts of Iron IV is for players who like the long game: planning an economy years ahead, reading the frontline, timing the decisive offensive. The learning curve is steep, but the depth is nearly bottomless, and an active modding and multiplayer community keeps it alive years after release. If that's your kind of game, check out Paradox's other grand strategies too: Europa Universalis IV for the age of great powers, Crusader Kings III for medieval dynasties and Victoria 3 for the industrial 19th century.
