Yes, Astroneer supports crossplay, but only partially.
Partially — Astroneer supports limited crossplay, so only some platforms play together. Cross-progression is not supported, so your saves stay tied to the platform you play on.
Astroneer is available on the following platforms:
| Feature | Supported | Details |
|---|---|---|
| Crossplay | Partial | Only some platforms play together — see the details below. |
| Cross-Progression | No | Saves and unlocks stay tied to each platform. |
| Split Screen / Couch Co-op | No | Online multiplayer only — no shared-screen play. |
No — Astroneer does not support cross-progression. Saves and unlocks stay tied to the platform where you earned them.
Astroneer has no cross-save: your saves live on the platform you play on and do not transfer between Steam, Xbox, PlayStation or Switch. The Nintendo Switch edition is the most isolated of all — it has no crossplay and no dedicated-server support, so Switch players can only play with other Switch players.
No — Astroneer does not offer split screen or couch co-op. To play together, each player needs their own system running the game.
There is no local co-op or split screen in Astroneer. Every multiplayer session is online, so each player needs their own copy and device; two people cannot share one screen or one console.
Astroneer's crossplay depends on how you play. Native, invite-based co-op only works between Xbox and the Microsoft Store (PC) version through Xbox Live. To connect Steam, PlayStation and Xbox players together you need an official dedicated server rented from a Microsoft-preferred partner such as Nitrado or GPortal — those official servers are the only ones that enable crossplay, along with achievements and cosmetics. Xbox and the Microsoft Store version can only join these authorised servers, not a self-hosted one; Steam and PlayStation can self-host, but that does not bridge Xbox.
Astroneer plays perfectly well solo and offline — you can explore and terraform whole planets on your own with no internet connection. Co-op is an optional layer on top, for up to four players in a standard session, or up to eight on a dedicated server.
Partially. Xbox and the Microsoft Store (PC) version play together natively, and Steam, PlayStation and Xbox players can be mixed on a dedicated server. The Nintendo Switch version has no crossplay.
Yes, but not natively — a Steam player and an Xbox player can only share a game through an official rented dedicated server (such as Nitrado or GPortal). Xbox cannot join a self-hosted server.
Only through a rented, authorised dedicated server. PlayStation cannot play with other platforms in a normal invite-based session, and it cannot connect to an unofficial self-hosted server.
No. Astroneer does not support cross-save or cross-progression. Your saves are tied to the platform you play on and do not carry between Steam, Xbox, PlayStation or Switch.
No. There is no split screen or local co-op. All co-op is online, so each player needs their own device and copy of the game.
