Prepare the session
Use the official ceiling of four and update everyone before troubleshooting a failed join. Version 1.0.005 specifically added a version-mismatch message for multiplayer, which makes inconsistent builds the first documented check.
The store also exposes multiplayer and online co-op categories. It does not explain a dedicated-server workflow or promise that a guest's mission completion transfers to another save.
Keep unknown networking details unknown
Community threads prove players ask about dedicated servers and progression in a friend's game. Until the developer documents those behaviors or a controlled test records them, this site does not turn assumptions into features.
