Direct answer
Current developer guidance states that Solarpunk does not currently support full crossplay.
That means the safe answer for purchase-intent users is no full cross-platform multiplayer support has been verified across Steam, Xbox, PlayStation 5, and Nintendo Switch 2.
Crossplay matrix
| Combination | Status | Evidence | Last verified |
|---|---|---|---|
| Steam ↔ Xbox | Not supported | Developer expectation-setting says no full crossplay | 2026-06-11 |
| Steam ↔ PS5 | Not supported | Developer expectation-setting says no full crossplay | 2026-06-11 |
| Steam ↔ Switch 2 | Not supported | Developer expectation-setting says no full crossplay | 2026-06-11 |
| Xbox console ↔ Xbox PC app | Not verified | Xbox Play Anywhere is confirmed, but that is not enough to declare full multiplayer compatibility | 2026-06-11 |
| PS5 ↔ Switch 2 | Not supported | Developer expectation-setting says no full crossplay | 2026-06-11 |
What is supported instead
The lack of full crossplay does not mean the game lacks multiplayer.
Official sources currently support these multiplayer facts:
- solo play exists
- online co-op exists
- PS5 and Nintendo Switch 2 listings currently indicate up to four online players
- each player has a separate inventory
- each player can build their own Airship
- multiplayer is host-based
- no public dedicated servers are currently expected
So the user-facing distinction should be:
- multiplayer: yes
- full crossplay: no
Xbox Play Anywhere is not the same thing as crossplay
This is the most common confusion to avoid.
Xbox Play Anywhere can describe purchase/access flexibility inside Microsoft's ecosystem, but it should not be rewritten as:
- full PC-to-console crossplay
- Steam-to-Xbox compatibility
- general cross-platform support
Those are separate claims and require separate evidence.
How to phrase the answer safely
For high-confidence copy, use wording like:
Solarpunk supports online co-op, but current developer information says it does not support full crossplay.
That sentence is short, commercially useful, and aligned with the current evidence set.
What could change later
Crossplay status is volatile compared with evergreen gameplay basics. If the developers add new compatibility support after launch, this page should be updated with a new verification date and a revised matrix instead of relying on older summaries.
