Big Walk Crossplay: Platforms and Join Codes
Confirm crossplay support, compatible platforms, and the verified joining flow.
Quick answer: is Big Walk crossplay?
Yes. Big Walk supports crossplay across its supported versions on Windows and Mac, PlayStation 5, and Nintendo Switch 2. Players can join a host through the platform friend list when available or use the host's short Join Code across systems.
The supported-platform and connection details below were checked on August 11, 2026. They are dynamic product information, not a promise about future platforms.
Supported platforms
| Platform | Supported version | Crossplay | Joining note |
|---|---|---|---|
| Windows | Steam | Yes | Platform friends or Join Code |
| macOS | Steam | Yes | Platform friends or Join Code |
| macOS | Mac App Store | Yes | Use a Join Code; this version does not use Game Center friend games |
| PlayStation 5 | PlayStation Store | Yes | Platform friends or Join Code |
| Nintendo Switch 2 | Nintendo eShop | Yes | Platform friends or Join Code |
The official FAQ says no other platforms are planned at the current check date. This page does not speculate about Xbox, earlier Nintendo hardware, or later ports.
Host and Join Code flow
- The host starts the session and waits until their character has loaded into the world.
- Friends on the same platform service should see the active host game in the friend-games menu.
- For cross-platform groups—or players who are not platform friends—the host shares the short Join Code generated for that session.
- Before the session starts, the code appears in the corner of the host menu. After starting, the host can find it under Session Details.
- Anyone who knows the code can attempt to join, so use a session password when the group needs access control. Do not expose the code or password on a stream.
Version matching requirement
A Big Walk version has three numbers, such as 1.2.3. According to the official FAQ, the first two numbers must match for players to connect. The third number may differ.
If a crossplay group cannot join, compare those first two version numbers before changing network settings. Update any out-of-range installation, then try the normal friend or Join Code flow again.
If the host does not appear
- Confirm the host is actually inside the world, not still in a menu.
- On the same platform service, verify that the players are registered as friends.
- On Mac App Store, skip the friend-list expectation and use the Join Code.
- Check any connection warning shown to the host in the lower-left corner.
- Confirm every device has an internet connection and an accurate system clock.
- If the group still cannot connect, fully close Big Walk on the host and joining devices, reopen it, and try again.
These are the current official checks. The reviewed sources do not establish a universal crossplay error code or a single cause for every failed connection.
