Quick answer
[Official] Yes, Big Walk autosaves group progress on the host's game. The host is the keeper of the save, so the same host must start a returning session when the group wants to continue from the same point.
How saving works in Big Walk
- Choose a host who is likely to attend future sessions, because that player's game keeps the group save.
- Have the host start the session and load into the world before guests connect.
- Play normally; Big Walk saves the group's progress automatically on the host's game.
- For the next session, have the same host start the saved journey before the group joins.
Can you transfer a Big Walk save to another host?
[Official] The reviewed FAQ identifies the host as the keeper of the save and does not document a way to transfer that save to another player. Do not assume that starting a session with a different host will continue the original host's progress.
What happens when the host leaves?
[Official] When the host stops the session, every guest is disconnected. To continue the same journey later, the original host needs to host again before the other players reconnect.
