Steam multiplayer guide
Trying to play with a friend? Use a Steam invite for a private game, or make the lobby Public and share its Lobby ID.
Looking for the Session ID? The game calls it a Lobby ID. The host uses Copy Lobby ID, and the other player joins with Search by ID.
Choose the right route
Want a private game? Use Invite Only and send a Steam invite. Joining with an ID? Set the session to Public and share the Lobby ID only with the people you want to join.
01 · Invite Only
Private lobbies are invite-only. Choose this route when everyone is already on your Steam friends list. The host needs to be inside the world before sending the invite.
Changed the session type? Restart the session before trying again.
02 · Public + ID
Can’t find one of these buttons? A later game update may have changed the menu label.
Public and Invite Only sessions both support Steam invites or the in-game Find Steam Friends option. Wait until the host is inside the world before sending or accepting the invite.
Black screen, lobby not found or timeout
Start with the quick resets below. Stop when both players can see and join the same lobby.
Update the game on both PCs before testing the lobby again.
Close the game completely, restart the Steam client, then reopen the game.
If the relay status is red, use the game’s Discord link to open its common-bugs guide.
Have the host load into the new world, then send a new invite or Lobby ID.
Is Find Steam Friends empty? Some players say the Steam Overlay setting affected this menu for them. This workaround comes from player reports and may not help every setup.
Keep your save files and avoid third-party connection tools. None of these steps requires either.
What changed in recent patches
Increased the maximum lobby size from 4 to 8 and attempted to fix a black screen when joining.
Added the Steam Relay status on the main menu so players can spot a failed relay connection.
Changed connection timeouts. Game, Steam and network problems can still stop a lobby from connecting.
Updated MetaVoice and stopped FishNet from overriding your maximum FPS when joining a lobby.
Quick answers
The game calls it a Lobby ID. Once the host has loaded a Public world, choose Copy Lobby ID and send the code to your friend.
Ask the host for the Lobby ID. Open Join Multiplayer, enter the code, then choose Search by ID.
Use Invite Friend or a Steam invite for an Invite Only lobby. Joining with a Lobby ID requires a Public session in the current menu flow.
Up to eight players can join, according to the Patch 1.0.4 notes.
Recent patches addressed black screens, Steam Relay and connection timeouts, but a lobby can still fail because of a game, Steam or network problem. Work through the checks above in order.
