Do this first
The quick route
- Have one person start and host the session.
- Open Session Details and copy the current Join Code.
- Share the Join Code and required Session Password privately.
- Enter both in Big Walk; platform friend status is not required for this route.
- If joining fails, confirm that the first two version numbers match.
Which platforms can play together?
The publisher's FAQ lists Windows and Mac, PlayStation 5, and Nintendo Switch 2, and confirms that these supported systems can share a session.
- Windows via Steam
- Mac via Steam or the Mac App Store
- PlayStation 5
- Nintendo Switch 2
The simplest route for a mixed-platform group
Use a Join Code instead of relying on a platform friends list. Big Walk generates a short, unique code whenever the host starts a session. Version 1.4.9 also made Session Passwords required, so guests need both current values.
What crossplay does not mean
Crossplay does not add Xbox support and it does not move ownership of a journey. The official FAQ says no other platforms are planned at this time, and the host remains keeper of the save. Use the same host to continue that journey later.
