Is Oxygen Not Included Cross Platform? Crossplay Guide 2026

No, Oxygen Not Included doesn’t support cross-platform play. This colony survival simulation from Klei Entertainment is a single-player experience that doesn’t feature multiplayer functionality, making crossplay irrelevant for this title.

Oxygen Not Included Cross-Platform Support Explained

Oxygen Not Included operates as a purely single-player colony management game where you guide duplicants through the challenges of space survival. Since the game doesn’t include any multiplayer modes, cooperative play, or online features, cross-platform compatibility simply doesn’t apply to this title.

The game is available on PC (Windows), macOS, and Linux through Steam, but these versions exist as standalone single-player experiences. You won’t find lobby systems, friend invitations, or any networking features because Klei Entertainment designed Oxygen Not Included as a solo strategic challenge focused on resource management and base building.

While some players might hope for future multiplayer additions, Klei Entertainment has never announced plans to introduce cooperative or competitive modes to Oxygen Not Included. The game’s complex systems and real-time pausable gameplay are specifically tailored for individual play sessions rather than shared experiences.

Which Platforms Can Play Together?

Since Oxygen Not Included is single-player only, here’s the platform availability breakdown:

Platform	Crossplay Supported	Notes
PC (Windows)	N/A – Single-player only	Available via Steam
macOS	N/A – Single-player only	Available via Steam
Linux	N/A – Single-player only	Available via Steam

Why Oxygen Not Included Doesn’t Have Crossplay

Oxygen Not Included doesn’t need crossplay because it’s fundamentally designed as a single-player experience. The game revolves around managing your colony of duplicants, researching technologies, and surviving environmental challenges. These activities work best when you have full control over the game’s pace and decision-making.

The game features a pausable real-time system that lets you halt the action to plan your next moves, examine complex systems, or respond to emergencies. This mechanic wouldn’t translate well to multiplayer scenarios where multiple players would need to coordinate pausing and unpausing the game world.

Additionally, Oxygen Not Included’s intricate systems like gas physics, temperature management, and resource allocation require careful individual attention. Adding multiplayer functionality would fundamentally change the game’s core design philosophy and potentially compromise the strategic depth that makes it appealing to its dedicated player base of over 10,000 active users.

Cross-Platform Save and Mod Compatibility

While crossplay isn’t applicable, you might wonder about save file compatibility across different operating systems. Steam Cloud saves work across Windows, macOS, and Linux versions of Oxygen Not Included, allowing you to continue your colonies on different computers running different operating systems.

Your save files will sync automatically through Steam Cloud if you have this feature enabled. This means you can start a colony on your Windows PC and continue playing it on your Mac laptop without losing progress. The game maintains full save compatibility across all supported platforms.

Modding support also works consistently across platforms through the Steam Workshop. Popular mods like Quality of Life upgrades, automation improvements, and new building options function identically whether you’re playing on Windows, macOS, or Linux. The modding community has created hundreds of compatible modifications that enhance the base game experience regardless of your operating system.

Limitations to Keep in Mind

The biggest limitation is obviously the lack of any multiplayer functionality. If you’re looking for a colony sim that you can play with friends, Oxygen Not Included won’t meet those needs. You’ll need to look at alternatives like RimWorld with multiplayer mods or dedicated cooperative survival games.

Performance can vary between platforms, particularly on older Mac hardware or certain Linux distributions. The game’s complex simulation systems can be demanding, especially in late-game colonies with hundreds of duplicants and intricate automation systems. Make sure your system meets the recommended requirements regardless of platform.

Some quality-of-life features like certain keyboard shortcuts or input methods might behave slightly differently across operating systems. However, these differences are minor and don’t significantly impact the core gameplay experience. The Steam version provides the most consistent experience across all supported platforms.

Can I play Oxygen Not Included with friends online?

No, Oxygen Not Included is strictly a single-player game with no multiplayer, cooperative, or online features. You can’t join friends’ games or invite others to help manage your colony. The game is designed as a solo strategic experience where you alone control your duplicants and make all colony management decisions.

Will my save files work if I switch between PC and Mac?

Yes, Steam Cloud saves ensure your progress transfers seamlessly between Windows, macOS, and Linux versions of Oxygen Not Included. As long as you’re logged into the same Steam account and have Steam Cloud enabled, you can continue your colonies on any supported platform without losing progress or having to start over.

Do mods work the same way across different operating systems?

Yes, mods downloaded through the Steam Workshop function identically across Windows, macOS, and Linux versions of Oxygen Not Included. The modding system is platform-agnostic, so popular gameplay modifications, quality-of-life improvements, and new content additions will work consistently regardless of which operating system you’re using to play the game.
