Big Walk is a multiplayer game to its core: you cannot play it alone, and you are not meant to. Here is everything the official FAQ confirms about how playing together actually works.
Quick answers
| Question | Answer |
|---|---|
| How many players? | 2–12 online |
| Single-player mode? | No |
| Matchmaking? | No — you invite people you know |
| Crossplay? | Yes, full crossplay on all platforms |
| Local / couch co-op? | No — not possible |
| How do I join friends? | Join Code or friends list |
| How does saving work? | The host's game autosaves |
How hosting works
Sessions in Big Walk are host-based. One player hosts the world, and everyone else joins that player's game.
When starting, the host picks a world version sized for the group — tuned for 2, 3, or 4+ players — and the world adapts to that size. So a duo and a full group of twelve are walking through versions of the island shaped for them.
Saving is just as simple: the host's game saves automatically. There's no manual save and nothing for guests to manage — when the group returns, you rejoin the host's world and carry on. (This is the complete answer to "how do I save in Big Walk" — see the beginner FAQ for more.)
Join Codes and the friends list
There are two ways in:
- Join Code — the host shares a code, and anyone with it can join the session.
- Friends list — join friends directly through your platform's friends list.
There is no matchmaking with strangers, by design. Big Walk is built around talking — proximity voice chat is the heart of the game — and that works best with people you actually know.
Crossplay
Big Walk has full crossplay between all platforms: Steam (PC and Mac), Mac App Store, PS5 and Nintendo Switch 2. Any mix of those can share a single session — the host's platform doesn't restrict who can join.
Why there is no local co-op
No couch co-op — and it's deliberate. The official FAQ explains that playing in the same room isn't possible: the game is built around proximity voice chat, so sitting side by side you would simply hear each other's real voices instead of the game's spatial audio. Each player needs their own device and copy.
Voice chat and troubleshooting
Proximity voice chat means your friends sound close when they're close and fade as you wander apart — and tools like walkie-talkies extend that range across the island. A few known issues from the official FAQ:
- Voice too quiet? Some players get quiet voice chat — it's a known issue, so check your voice settings first.
- On PS5? There's a dedicated voice-chat mute toggle on PS5.
- Performance problems? Lower the Render Scale in settings.
Getting started
Grab the game on Steam or your platform's store, decide who hosts, share the Join Code — and start walking. If your group is wondering how much time to set aside, see how long Big Walk takes.
