Is Hearts of Iron IV Cross Platform? Crossplay Guide 2026

Hearts of Iron IV doesn’t offer full cross-platform play like you might expect. While the game supports multiplayer among PC, Mac, and Linux users, everyone needs to be on the same store platform. This means Steam users can only play with other Steam users, regardless of their operating system.

The Cross-Platform Situation Explained

Hearts of Iron IV comes from Paradox Development Studio and is playable on PC, macOS, and Linux. At first glance, this seems like great cross-platform support — and to some extent, it is. A Windows player on Steam can host a game and invite a Mac or Linux friend who’s also on Steam. That’s the silver lining.

However, here’s the downside: cross-store multiplayer isn’t possible. If you’ve got Hearts of Iron IV through Game Pass or the Windows Store, you can’t play with someone who has it on Steam. The store platform acts as a barrier, and Paradox hasn’t introduced any way to connect these different player bases.

With around 21,236 active players, most folks are on Steam. This limitation mainly impacts Game Pass users who might have friends on a different platform.

Which Platforms Can Play Together?

Platform	Cross-Platform Compatible?	Notes
PC (Steam)	Yes — with Mac/Linux (Steam only)	Can play with Steam users on any OS
macOS (Steam)	Yes — with PC/Linux (Steam only)	Can play with Steam users on any OS
Linux (Steam)	Yes — with PC/Mac (Steam only)	Can play with Steam users on any OS
PC (Game Pass / Windows Store)	No — cannot play with Steam users	Restricted to same-store players only

Key Limitations to Know

• Same store required: All players must have the game on the same platform storefront.
• Same game version required: Everyone in a multiplayer session must be running the exact same version of Hearts of Iron IV. Different patches or DLC can prevent players from joining.
• No console version: Hearts of Iron IV isn’t available on PlayStation or Xbox, so console crossplay isn’t an issue.
• No cross-save: There’s no official cross-save feature between different platforms or storefronts.

How to Play Multiplayer in Hearts of Iron IV

1. Launch Hearts of Iron IV on Steam.
2. From the main menu, select Multiplayer.
3. Choose to host a game or browse existing lobbies.
4. Invite friends via the Steam friend list or share the lobby link directly.
5. Make sure all players are on the same game version before starting.

As long as everyone is on Steam — whether they’re on Windows, Mac, or Linux — the session should run smoothly without any extra setup.
