Host for the intended group
Choose a host
One player starts a hosted game. Have that player choose the documented invite-only setting instead of a publicly joinable session.
Invite the intended players
Send the game invitation to the friends you want in the session. Have them accept/join from the matching platform client; do not assume a different storefront can join because both clients run on PC.
Verify the group in the lobby
Confirm that the intended players arrive. If the host is playing alone, invite-only hosting is the recorded solo-lobby route; it still uses the hosting system.

Check accounts, permission and any password prompt
- Sign in to the account used by the game. The September patch now gives a failure message when a joining player is not signed in.
- If a crossplay permission prompt appears, the update says the choice is respected during joins. A permission setting is not proof that Steam and the Xbox ecosystem share every lobby.
- If joining asks for a password, obtain it from the host. The September patch explicitly fixes submitting a lobby password through the on-screen keyboard.
- The sources do not establish that invite-only and password protection are the same option, or that every private invitation needs a password.
Official player-count descriptions differ between Steam and Xbox. Do not treat the promotional 50/30-player wording as a tested private-lobby limit.

Who can join or remain
Invite-only is the documented host choice for keeping a session from public joining. The update also confirms host identity verification, account crossplay privileges and kick messages. It does not supply the current exact location of a host’s kick control.
If an invited player fails to enter, use the connection checklist to separate sign-in, permission, timeout and host-connection problems. Repeated invitations do not establish that an incompatible store pair can join.
If the goal is two players sharing one screen, check the split-screen status before buying controllers or extra access.
Before sharing a lobby with another store version, compare the crossplay matrix and its evidence scope. For a trip without internet, use offline preparation; an invite-only lobby still uses online services.
