Is Waterpark Simulator Cross-Platform?
Cross-platform multiplayer has not been announced or marked on the official store pages.
As of August 13, 2026, official pages confirm online co-op on Steam, PS5 and Xbox Series X|S, but they do not confirm cross-play between those platforms. That means the correct status is “not announced,” not a claim that cross-play is permanently impossible.
What to do
If your group wants to play now, use the same platform family and confirm the lobby appears before purchasing extra copies. Store capability lists describe online play on each platform, but none of the researched official pages carries a cross-play label or announcement.
What the sources support
Steam, PlayStation and Xbox are all official 1.0 platforms with 2–4 online co-op. The absence of a cross-play marker supports only an unresolved status; it does not prove a technical restriction.
Version notes and limits
This can change after a platform update. Recheck the official game site and store capability labels before relying on the status for a purchase.
